Polyolefin Shrink Film
Search
Cross-linked POF (Polyolefin) shrink film is a high-performance, multilayer co-extruded heat shrink packaging material that undergoes a cross-linking process to significantly enhance its physical and mechanical properties. It combines exceptional clarity, strength, and sealing characteristics, making it ideal for high-speed packaging lines and demanding packaging applications.
Available thickness: 10um, 12um, 15um, 19um, 25um.
Film width: can be customized as per packaged goods specification.
● Cross-linking Technology: Enhances tensile strength, impact resistance, and heat tolerance; improves shrink consistency and overall durability.
● Superior Clarity and Gloss: Presents products in a clean and attractive manner, ideal for retail display.
● High Shrinkage Rate: Uniform and balanced shrink in both MD (machine direction) and TD (transverse direction), providing tight and wrinkle-free packaging.
● Strong Seal Integrity: Excellent hot slip and cold resistance, ensuring firm seals even under challenging conditions.
● Wide Shrink Temperature Range: Adapts to various shrink tunnels or heat guns (typically 120–180°C).
● Puncture & Tear Resistance: Ideal for packaging items with sharp edges or irregular shapes.
● Eco-Friendly & Food Safe: Non-toxic, recyclable, and compliant with FDA and EU food contact regulations.
√ Retail Packaging: Toys, cosmetics, books, electronics, DVDs, promotional kits.
√ Food Packaging: Baked goods, snacks, frozen food, fruit trays (available in food-grade quality).
√ Industrial Packaging: Tools, automotive parts, electronics, household appliances.
√ Multi-pack Bundling: Bottled water, cans, cosmetics sets, and promotional combos.
