78% Shrink Rate｜Perfect Fit with PETG Shrink Film

PETG Shrink Film – Key Aspects of the Shrinkage Rate Test include:

• Uniformity of Shrinkage – Evaluation of even shrinkage across the entire film surface to avoid wrinkles, distortion, or uneven label application.
• Dimensional Accuracy After Shrinking – Verification that the film maintains correct proportions and alignment for precise label positioning.
• Print/Graphic Registration Stability – For printed films, assessment of image alignment and sharpness after the shrink process.
• Heat Resistance & Controlled Contraction – Testing the film’s ability to shrink consistently under specified heat conditions without excessive deformation.

This test is essential for applications such as full-body labeling, contoured bottle decoration, and premium product packaging, where precise shrinkage performance directly impacts visual appeal and brand presentation.
