China Cross Link POF Shrink Wrapping Film Suppliers - Factory-Direct High Strength and Enhanced Shrinkage Rate

In our factory in China, we utilize advanced radiation cross-linking technology during the production of our shrink film. This innovative process transforms the polymer chain of the resin from a linear structure into a mesh-like configuration, resulting in enhanced properties for our packaging solutions, One of the key benefits of our shrink film is its exceptional shrinkage rate, reaching up to 80%. This high shrinkage rate ensures that the film adheres closely to the product, providing superior packaging performance. Additionally, our film boasts improved strength and toughness, making it an ideal choice for robust packaging needs, The thermal sealing performance has also seen significant improvement, ensuring that seals are tighter and eliminating any drawing phenomena in sealed areas. Furthermore, our shrink film is designed with enhanced heat and cold resistance, allowing it to perform effectively across a wider range of temperatures. As a leading supplier in the industry, our products are tailored to meet diverse packaging requirements while maintaining exceptional quality

Frequently Asked Questions
Q1 What is Cross-Linked POF Shrink Film and how does it differ from regular POF film?
Cross-linked POF (Polyolefin) shrink film undergoes a special irradiation or chemical cross-linking process that creates molecular bonds between polymer chains. This results in significantly higher tensile strength, superior tear resistance, better seal integrity, and more consistent shrinkage performance compared to standard POF film — making it ideal for demanding packaging applications.
Q2 What gauges (thicknesses) are available for this Cross-Linked POF Shrink Film?
The film is available in five standard gauges: 12μm, 15μm, 19μm, 25μm, and 30μm. Each gauge offers different mechanical and optical properties, allowing customers to select the most suitable thickness based on their product weight, packaging requirements, and desired shrinkage characteristics.
Q3 At what temperatures does this shrink film perform best?
The film demonstrates excellent shrinkage performance across a range of temperatures. Free shrinkage increases progressively from 100°C through to 130°C, reaching up to 81% (TD) and 81% (MD) at 130°C. Shrink tension peaks at around 120°C. This wide operating range makes it compatible with most standard heat tunnel and hot wire sealing equipment.
Q4 Is this POF shrink film suitable for automatic packaging machines?
Yes. This cross-linked POF shrink film is specifically engineered for use on automatic packaging machines. Its consistent thickness, stable coefficient of friction (COF), and reliable sealing strength ensure smooth, uninterrupted operation on high-speed L-bar sealers, side-seal machines, and other automated shrink packaging equipment.
Q5 What industries and products is this shrink film most commonly used for?
This film is widely used across multiple industries. It is especially popular in high-end cosmetics packaging, consumer electronics, food and beverage, pharmaceuticals, stationery, and gift products. Its low haze, high clarity, and excellent gloss make it the preferred choice for brands that require premium presentation and shelf appeal.
Q6 Is this Cross-Linked POF Shrink Film environmentally friendly and recyclable?
Yes. The film is designed with sustainability in mind. It is recyclable and supports circular economy principles by reducing plastic waste. Its lightweight nature also contributes to lower transportation emissions and a reduced overall carbon footprint, making it a responsible choice for brands committed to environmental sustainability goals.
