Trustworthy China Pet Bottle

Pet Preform come in a variety of sizes, shapes and colors. They range from opaque to translucent or transparent, so different measurement techniques are required depending on the type of sample.

Opaque pet preforms are opaque and are preferably measured using a diffuse d/8 ball reflector.

Translucent preforms allow light to pass through, but only diffuse, so it is not possible to clearly distinguish objects on the other side. Both the reflection and transmission measurement modes work well depending on the translucency of the sample. Based on experience,

– If your customer will view the path length of the sample, you can see the slight detail of the thumb or finger through the preform, and then the transmission is the preferred method of measurement.

– If you don’t see the details, the reflection is preferred.

The path length is defined as the thickness of the sample from the point where the light enters the sample to the thickness of the sample.

Transparent preforms allow light to pass through with little or no interruption or distortion so that objects on the other side can be clearly seen. These pet preforms can only be measured using a gearbox gauge.
