PVC Shrink Labels
- Shrink labels makes product presentable, boosts shelf impact and augments consumer responsiveness.
- Cast PVC Shrink Film (Shrink-label films) covers the entire body of product allowing printing of more information and intricate designs.
- The print quality is outstanding. Access to reverse print protects labels from scratches and wear while preserving a high-gloss finish.
- Shrink films goes well with peculiarly shaped containers that discern product on the shelf.
- Full-body shrink labels can display the product inside and allow to create easy opening, tamper-evident seals.
- Our films are manufactured in a controlled environment to the strictest manufacture standards.

closures - Suitable for Manual, Roll-fed & Shrink wrap-around labels
Comparing PET Shrink Film with PVC Shrink Film
- PET heat shrinkable sleeve film undergo higher TD shrinkage and are more sensitive to temperature. Since the shrinkage range is narrower, it will suddenly shrink when the temperature reaches 75-80℃. However, for PVC film, the shrinkage range is wider and the shrinkage speed is also slower.
- The MD stretching strength of PET films is higher than that PVC products, and the elongation rate is higher than PVC films.
- The COF (coefficient of friction) of PET heat shrinkable sleeve films is better than PVC, which is more convenient for printing and labeling
- The thickness homogeneity and printing properties of PET film are better than that of PVC.
Comparison for Printing Application
| Characteristic | PET | PVC |
|---|---|---|
| Maximum Shrinkage Rate (%) | 78 | 65 |
| Crispness | Good | Bad |
| Transparency | High | Normal |
| Shrinkage Temperature (°C) | 80 | 60 |
| Resistance to low temperatures | Better than standard | Standard |
| Density | 1.33 | 1.37 |
| Storage Stability | Good | Bad |
| Environmental consequence during disposal | Lower than that of PVC since during recycling, amount of PET can be lowered after treatment | During recycling, poisonous exhaust gas is generated when film is burnt |
Advice for Adhesives
- Recommended : 1,4-dioxane=100%
- The actual ratio and recipe should be set according to the distance between the gumming location and gluing location of the gluing machine. The customers can conduct an experiment to confirm the actual gluing effects.
- The recommended storage temperature should be no higher than 30℃
- The storage temperature for all of the base films and printed labels should be no higher than 30℃ before sleeve labeling. Else, it may cause broken labels.
Transportation of the film
- When carrying the base film, it should be handled gently. It can be placed only horizontally, not vertically
- The 2 ends of the film roll can’t touch the floor. When taking the film roll off of the pallet, it is recommended to put the roll horizontally on the floor and then remove the plywood. Make sure not to place the rolls vertically on the floor to remove the plywood – that will cause damage to the film or the film roll may be out of shape, which will affect the application of the films.
- The temperature during transportation should be no higher than 30℃
