China Pet Bottle Is More Worthy Of Choice

PET is the abbreviation of polyterephthalic acid. The forming principle of PET bottle is divided into two types, injection stretch blow molding and extrusion stretch blow molding. The former is more widely used in process.

The forming principle of the pet bottle is to expand the preform volume according to the contour of the mold by the blow molding machine under high temperature and high pressure conditions in the mold, thereby forming a hollow packaging container with a certain shape and cooling, and then cooling the mold release, with the growth of the blowing technology. The mold grows and the yield is extremely increased. It can process tens of thousands of pet bottles per hour, and all the computer program control system is changed, which increases the stability of the process. The important factors affecting the blow molding process of the PET bottle are temperature control. , heating environment, pre-blowing, etc. Pet Preform and pre-blowing should be noted that the preforming principle of preforms is similar to that of pet bottles. The difference is that the molds and equipment are different. The preforms are hollow specimens that are injected into the mold of the injection molding machine and then formed by high temperature and high pressure. The molecular weight viscosity should not be too low, otherwise it will be easily damaged during the blow molding process. The processing technology of the preform is more mature, and the production efficiency is almost 10 times that of the pet bottle. The influencing factor of the pre-blowing is mainly the flow rate, that is, the feed rate. Should not be too fast, should be the machine processing peak is lower 1/4, domestic equipment (injection molding machine, blow molding machine) are mostly manufactured in Germany and France, have preform supply system, temperature control system, host system, The heating system and the auxiliary manual control system are composed of five parts. With the advancement of the machine and equipment, the manual operation is very important, the program parameters are set, and the automatic production is very stable.

PET material has hygroscopic properties, so in the air, pet preforms or pet bottles will absorb moisture in the air, should be stored in a dry and ventilated place, pet bottles generally have poor heat resistance, mostly used for cold filling, but By changing the mold and changing the shape of the pet bottle, hot filling below 145 degrees Celsius can be achieved.

PET bottles are widely used in beverage packaging, pharmaceutical packaging, cosmetic packaging, glass beer bottles and liquor bottles due to their light weight (about 1/10 of the same volume of glass bottles), non-fragile, stable light transmission and non-toxicity. There have been repeated injuries and it is not easy to recycle. Foreign countries have already turned to PET bottles, and the market prospects for pet bottles are very good.

How To Choose High Quality Pet Preform

The use of Pet Preform is very common in our lives, with water buckets, cups, including PET water tanks. The storage of fresh food and the PET pot for cleaning clothes belong to the category of PET containers. The quality of pet preforms is closely related to our lives. The PET container is light in weight, not easy to be broken, and is not easily oxidized and corroded, and can be used continuously. However, the harmful substances doped in a good PET container in the production process will be relatively qualified and will not cause harm to the human body, so When we choose pet preforms, there are small tricks.
1. When buying a PET container, pay attention to the appearance of the PET container to see if it is damaged, especially if you look at the thickness of the PET container, and if there are black spots on the surface of the container.
2. Because the main material of the PET container is a variety of chemical compounds, the chemical composition will emit harmful substances in case of extreme conditions, and must be carefully selected when selecting. There is a small mark under each PET container, usually at the bottom of the PET container, a small triangle with 1 to 7 numbers in the small triangle. Each number represents a different material, and we can choose a PET container based on the number.
3. Smell the smell of the PET container. Generally, the taste of the PET container will be lighter than that of the poor quality PET container. The plastic taste of the bad quality container is relatively strong.
4. When choosing a PET container, you should pay attention to its color, look at the sun, view from the side, if it is turbid, it is better than the transparent one, which means that the chemical composition of this inclusion is relatively small.
The above is a little experience when choosing pet products. If you want to buy reliable pet products directly, then Jilian mold is your choice not to be missed. We produce high quality and reliable China Pet Bottle, and they are very affordable in price. If you are interested, please come to us. Leave a message.

China Pet Bottle That Makes You Satisfied

Pet Preform packaging has always been a large-volume production model, and pet preform manufacturers can only rely on large-scale production to win profits. Because the profit of a single pet preform is very low. At the same time, the pet bottle needs to be shaped by the mold, so if you need a personalized pet bottle you need to re-open the mold.

However, with the development of the market, high-end luxury goods consumption is increasingly sought after by the market. Young people are increasingly demanding personalized packaging. For example, last year’s personalized pet bottle label launched by Coca-Cola, printed on the pet bottle label with different labels such as “youth” and “happy” to cater to the individualized appeal of young people. Has won the pursuit of many young people. Nowadays, there is a growing demand for personalized customization of pet bottle packaging in China. In this regard, we believe that there are several professional private custom pet bottle companies that are urgently needed to meet this demand in the market. This market will be special, no longer a large batch of pet bottle ordering orders, but focus on the production and sales of boutique, personalized pet bottle packaging.

Jilian Plastic Mould is a China Pet Bottle manufacturer who is willing to keep trying. We are also improving the performance of our products in terms of personalization. We welcome all interested customers to come and contact us, we will bring you satisfaction. Products and services.

Factors Affecting The Blow Molding Of Pet Preform

Pet Preform and their heating, pre-blowing (position, pressure and flow), stretching rods, high pressure blowing (pressure, position) and molds are factors in the process that affect the bottle making of the blow molding machine.

1.PET preform

PET preforms, also known as parisons, are injection molded of PET pellets. They require that the proportion of recycled materials should not exceed 10% and the number of recycling should not exceed two. PET preforms after injection molding or PET preforms after heating must be cooled for more than 48 hours, and the PET preforms used should not be stored for more than 6 months. Different production dates, especially long-length PET preforms cannot be mixed. The main reason is that the raw material type of the PET preform, the proportion of the secondary material mixed in and the residual stress in the PET preform are different, and these factors have a significant impact on the molding process of the blowing bottle, and should be treated according to the actual situation.

2. Heating

The heating of the PET preform is done by a heating furnace, which is manually set and automatically adjusted. The height of the heating furnace is preferably about 25 mm, and is about 19.6 mm from the conveying wheel. The PET preform continuously runs through the entire oven on the conveying wheel, so that the PET preform is more uniform in heat and can be formed better, which overcomes the shortcomings of the previous PET preform static heating and manual rotation and uneven heating. However, if the heating furnace is improperly adjusted, it will cause uneven distribution of the wall thickness of the blown bottle (such as light weight), bottle mouth enlargement, hard neck and other product defects, and even cause mechanical component torsion failure. The temperature of each area can be adjusted according to the molding condition of the product, and the opening condition of the oven tube should be considered. In addition, the setting of the oven output power also has a large effect on the heating of the PET preform, which controls the output of the entire oven heat. When it is not turned on for a long time, when it is turned on again, the initial output power should be set higher accordingly, and then gradually reduced to the normal state during normal production. The output power is generally about 80%, especially when the ambient temperature is below 5 °C. The effect is more significant.

The blowing production process has a certain relationship with the production environment temperature, and the ambient temperature is generally room temperature (about 22 ° C). If the temperature is too high, the product is prone to agglomeration and agglomeration; the temperature is too low, the product performance is unstable when the machine starts, and the specific operation should be adjusted according to actual conditions and experience.

3. Pre-blowing

The role of pre-blowing in the blowing process is to have the PET preform begin to take shape while the longitudinal strength of the stretch rod is increased by longitudinal stretching. The whole process is that the pre-blowing cam pushes the three-way valve to the pre-blowing position during the blowing process, and is completed by the one-way valve. The pre-blowing position, pressure and flow can all affect the quality of the bottle.

Position: The pre-blowing position is advanced, there will be defects such as skewing and thinning of the center point of the bottom of the bottle, uneven wall thickness of the foot, whitening, light weight, hard neck, and even bottom penetration; after the pre-blowing position is wrong, There will be defects such as light weight, center point thickening, and depression.

Air flow The pre-blowing flow is controlled by a one-way valve, generally 3-4 turns is appropriate. The gas flow is large, the bottom is heavy, the center point is thin and partial, the foot is white, and the wall thickness is uneven; the gas flow is small, the center point becomes thick, and the segmented piece exceeds the standard.

Pressure: The pre-blowing pressure is preferably 0.8-1 MPa. When the pressure is high, the upper and lower weight may be light, the center point is skewed, the wall thickness of the foot is uneven, and the white is whitish; when the pressure is low, the foot is not fully stretched, the bottom is heavy, and the center point is thick.

The molding of the foot and the center of the bottle has the greatest impact on the quality of the bottle. Improper adjustment often causes fatal defects such as bottle explosion (under normal experimental conditions) and leakage.

In the market, Jilian Plastics has become a leader in China Pet Bottle by virtue of its own excellent strength. If you happen to have this demand, you must not miss us. If you miss us, you will regret it.

Multi-channel Promotion Of China Pet Bottle

Pet Preform are one of the most widely used packaging products for the packaging of the beverage, food, and pharmaceutical markets. However, in the current buyer’s market, excessive product competition is fierce. How to improve the competitiveness of pet preform enterprises?

1. Open up the unpopular and undeveloped market

For medical PET bottle manufacturers, in the traditional packaging field, when competitors compete to consolidate the market, it is obviously beneficial to the development of the enterprise if it can open up some markets that are relatively unfettered by other competitors. On the one hand, there are fewer companies producing these unpopular markets, and it is more difficult for buyers to find suppliers. Therefore, PET bottle manufacturers can appropriately increase the price of PET bottles and increase the profit of products. On the other hand, these markets have less competition. Although there are not many orders in normal times, there are orders on one order, because there are fewer competitors and the transaction probability is often larger.

In the past eight years, disposable PET bottles have occupied a considerable market share, and the quality of PET bottles is also increasing. The importance of PET containers is becoming more prominent, not only in the beverage market, but also in the food, cosmetics and pharmaceutical industries. New filling technologies and the development of heat-resistant PET bottles have opened up new possibilities and options. PET bottles are popular in beverage, cosmetic and sanitary product packaging, while detergent packaging uses PEPET bottles.

Internationally, with the increase of population, the improvement of living standards and the westernization of consumption patterns, the demand for PET bottles in some Eastern European countries will increase. In Eastern Europe, the per capita consumption of bottled beverages is still far lower than in Western Europe, which means that its future growth potential is quite large, and the market demand for PET bottles will also increase.

2, multi-channel promotion of PET bottles

We believe that manufacturers need to keep abreast of the various ways in which mobile phones can promote PET bottles. However, we believe that in the current situation, the focus of PET bottle manufacturers should be on the traditional network computer. This is mainly because the emerging mobile client promotion has no mature model on the one hand, it requires more energy, and it will have more expenses. On the other hand, the PET bottle promotion platform of the traditional network is very mature, and the habits of customers will not change very quickly in the short term. In this way, the focus should be on the traditional network.

3. Improve the quality of PET bottles

When a product develops for a longer period of time, the market competition will become more intense. At this time, manufacturers need to start from all aspects to deal with the competition problem. First of all, in terms of quality, only by improving the quality of the product itself, can we get more opportunities. However, if a good product is not known, the sales volume cannot be improved, so it is also very important in publicity. In today’s market situation, high-quality, low-cost, environmentally-friendly and degradable products are the first choice for customers, and they are the goal of manufacturers.

Jilian Plastics produces high quality China Pet Bottle. We constantly improve our product production technology, and also provide perfect after-sales service for the vast number of consumers. If you have such a demand, please come to contact us.

Jilian Mold For You To Build A China Pet Bottle

Pet Preform are typically manufactured from hot runner molds. It is preferred to have a thermal insulator between the mold and the injection molding machine. The thickness of the preform is approximately 12 mm and the insulator must withstand high pressure. Ventilation must be sufficient to avoid local overheating or air traps, but the depth of the ventilation slots should not exceed 0.03 mm, otherwise flashing can easily occur.

Melting temperature

It can be measured by air jet method and the temperature can be set between 270 and 295 °C.

Enhanced green fluorescent PET can be set to 290-315 ° C

Injection speed

Usually, the injection speed is fast, which prevents early coagulation during the injection process. But the speed is too fast and the high shear rate makes the material brittle. Shooting is usually done in 4 seconds.

Back pressure

The lower the back pressure, the better the injection effect to avoid wear. Generally no more than 100 bar.

Residence time

Do not use excessive residence time to prevent molecular degradation. Try to avoid temperatures above 300 ° C if the downtime is less than 15 minutes. Only air jets are required; if it is more than 15 minutes, clean with viscous polyethylene and bring the temperature of the tub down to the temperature of the polyethylene until it is turned back on.

other people

(1) Recycled materials should not be excessive, otherwise it will easily cause “bridge” and affect plasticization.
(2) If the mold temperature is not well controlled or the material temperature is not properly controlled, it is easy to produce “frost” and opacity.

How Can China Pet Bottle Develop Smoothly?

Pet Preform, as the middle semi-finished products of plastic bottles, have received more and more attention and welcome in the market in recent years. For the food and beverage manufacturers in the past, the purchase of plastic products has been the first choice. The plastic bottle can be directly filled as a finished product and pulled into the workshop, which is more convenient. However, for these food and beverage manufacturers, as the scale of production expands, the benefits of preforms begin to emerge. The preform is semi-formed compared to the raw material, which is more convenient to process, and more convenient to process. It can cooperate with the assembly line to realize a line of injection blowing. Therefore, the advantages of preforms will be greatly improved. Of course, the quality of the preforms also needs to be taken seriously, and the quality cannot be affected by the price. So what are the current problems in the pet preform market? How to solve or improve?

First: In order to increase the price advantage of products and their own profits, some manufacturers have become the unspoken rules of merchants by doping secondary materials in the production process of preforms. Although the secondary raw materials are cheap, there are still various problems that will affect the safety of food packaging. Therefore, it is necessary to strengthen supervision.

Second: pet preforms are easier to standardize than blow molded bottles of different shapes, and the development of standards is more conducive to market development.

Only when the China Pet Bottle is professional and the manufacturers are fine, the development will be smoother. Jilian Plastics has witnessed the development opportunities of the modern industry and sincerely serves the consumers and the market. Welcome everyone. Come and contact us.

Pet Preform Cost Less

Nowadays, the production process of transparent pet bottle packaging is welcomed and loved in the packaging field of food, beverage and cosmetics by virtue of its increasingly transparent appearance.

In the past, glass bottles occupied the protagonist position in the food and beverage packaging market with their transparent appearance. With the advent and addition of transparent pet bottles such as PET and PP, the advantages of transparent Pet Preform at lower cost have begun to prevail in the market.

Indeed, transparent pet bottles allow customers to see the contents of the package at a glance, and it is clearly very important for today’s untrustworthy food consumption. However, the production of transparent pet bottles is not as good as ours. In order to increase the transparency of pet bottles, BPA needs to be added. BPA is also known as bisphenol A. We all know that bisphenol A is harmful to the human body. Although under certain conditions, the structure of the pet bottle is stable and will not affect the human body. However, as the transparency increases, the amount of bisphenol A used will increase, which will only be detrimental to the human body.

Therefore, under the same conditions, our consumers can choose the pet bottle or the glass bottle that is not so transparent, so that the use will be more assured.

Jilian Plastics produces China Pet Bottle that people can rest assured. We strictly follow the standards of production and production to ensure that our products can be safely used in various industries to bring convenience and establishment.

China Pet Bottle Makes You Satisfied

Appearance and characteristics of transparent Pet Preform: high rigidity, oval pet bottle. However, the manufacturing cost of the mold is high. Therefore, in order to ensure the rigidity of the pet bottle, in addition to selecting the material with high rigidity, the shape of the pet bottle is also designed to enhance the rigidity and load resistance of the pet bottle.

Showing good advantages and effects, pet bottles should have sufficient rigidity and aesthetic appearance. Ability to play a role in different industries. The most common shapes for pet bottles are round, square, oval, and so on. From the point of view of use, each has its own advantages and disadvantages. Round pet bottles have a high stiffness but are not aesthetically pleasing. The square pet bottle has a beautiful appearance, but it is not easy to control the uniform thickness of the pet bottle during molding. The pet bottle not only has a good appearance, but also has good product performance and advantages, ensuring that it can make an important contribution in use.

It should be noted that the shape of the pet bottle should be symmetrical. Minimize the extreme stretching points and parts. The transition of the friends uses arc transitions.

China Pet Bottle Welcome Choice

What should I pay attention to when purchasing Pet Preform? Next, follow the Jilian mold to understand:

1. The pet bottle has a uniform wall thickness and the most concentrated part of the consumer’s attention. The printed appearance should be flat and continuous; if the liquid pet bottle contains handles, grooves, ribs, etc.

2. The printing surface of the pet bottle should be designed so that it cannot cause inconvenience to the printing operation. The label surface should be flat. A “frame” can be designed on the outside of the pet bottle to accurately position the label.

3. When the appearance of the pet bottle is marked, it does not move, such as the middle of the pet bottle is relatively thin,

4. Change the shape of the pet bottle and increase the circumferential groove or rib of the outer surface of the pet bottle to improve the rigidity and bending resistance of the pet bottle. Longitudinal grooves or ribs eliminate the offset, sagging or deformation of the pet bottle under temporary load.

What should I pay attention to when purchasing pet bottles?

If the material is high density polyethylene or polypropylene.

5. When designing a squeeze pet bottle, the cross section of the pet bottle should be rectangular or elliptical. For low density polyethylene or other flexible pet bottles, the cross section is round, so that the content is easy to pet from pet. Extrusion inside the bottle.

6. When blow molding, it tends to be hardened first. Therefore, the wall thickness of this part is also larger. At the edge and the corner, the final contact of the parison is inflated, and the wall thickness of the portion is small. Therefore, the edge and the corner of the pet bottle should be designed to be rounded.
