Frequently Asked Questions
Q What is Cross-Link POF Shrink Film and how does it differ from regular POF film?
Cross-Link POF (Polyolefin) Shrink Film is a high-performance packaging material that has been cross-linked to enhance its mechanical and optical properties. Compared to standard POF film, it offers higher tensile strength, better tear resistance, lower haze, and superior seal strength, making it ideal for premium packaging applications.
Q What gauges (thicknesses) are available for this shrink film?
This Cross-Link POF Shrink Film is available in five standard gauges: 12um, 15um, 19um, 25um, and 30um. Each gauge offers slightly different mechanical performance values to suit a wide range of packaging needs and product weights.
Q What industries is this shrink film most suitable for?
This film is widely used across various industries, with particular strength in high-end cosmetics, electronics, food, and consumer goods packaging. Its high clarity and gloss make it especially popular for premium retail products where visual presentation is important.
Q What shrinkage rates can be expected at different temperatures?
The free shrinkage rates increase with temperature. At 100°C, TD shrinkage is 23% and MD is 32%. At 130°C, both TD and MD reach up to 81%. This wide shrinkage range allows the film to conform tightly and uniformly around products of various shapes and sizes.
Q Is this shrink film compatible with automatic packaging machines?
Yes, this Cross-Link POF Shrink Film is designed for use on automatic packaging machines. Its consistent seal strength, stable COF (Coefficient of Friction), and reliable shrink performance ensure smooth operation on standard L-bar sealers and shrink tunnels.
Q Is this shrink film environmentally friendly and recyclable?
Yes. This film is designed with sustainability in mind — it is recyclable and supports circular economy principles. Its lightweight construction also contributes to reduced transportation emissions and a lower overall carbon footprint compared to heavier packaging alternatives.
