Frequently Asked Questions
Q
What is Cross Link POF shrink film and how does it differ from standard POF film?
Cross Link POF (Polyolefin) shrink film is a specially engineered film where polymer chains are chemically cross-linked, resulting in significantly higher tensile strength, better tear resistance, and superior optical clarity compared to standard POF film. It also offers firmer, more consistent sealing performance across a wider temperature range.
Q
What gauge thicknesses are available for this shrink film?
This Cross Link POF shrink film is available in five standard gauge thicknesses: 12um, 15um, 19um, 25um, and 30um. Each gauge offers different tensile, tear, seal strength, and shrinkage properties to suit various packaging requirements and product types.
Q
What industries and products is this shrink film most suitable for?
This film is widely used across multiple industries. It is particularly well-suited for high-end cosmetics packaging and electronics due to its outstanding optical properties (low haze, high clarity, and excellent gloss). It is also used in food packaging, gift wrapping, stationery, and any application where a clean, attractive finished appearance is required.
Q
At what temperatures does this film achieve optimal shrinkage performance?
The film achieves progressive shrinkage from 100°C up to 130°C. Free shrinkage values range from approximately 23–32% at 100°C up to 81% in both TD and MD directions at 130°C. For most automatic packaging machine applications, a tunnel temperature between 110°C and 130°C is recommended for optimal results.
Q
Is this Cross Link POF 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 lower transportation emissions and a reduced overall carbon footprint compared to heavier packaging alternatives.
Q
Can custom packaging solutions be made using this shrink film?
Absolutely. Custom packaging can be created by combining this shrink film with an automatic packaging machine. This allows for tailored packaging solutions designed to fit your specific product dimensions and presentation needs, making your products more visually attractive on the shelf.
