Frequently Asked Questions (FAQ)
What are the main advantages of Cross-linked POF shrink film over standard film?
Cross-linked POF film undergoes an electronic irradiation process that strengthens its polymer chains. This results in significantly higher tensile strength, superior puncture resistance, stronger seal durability, and a broader operating window on automated packaging equipment.
Which industries benefit most from using Cross-linked POF film?
Due to its crystal clarity, high gloss, and robust tear resistance, it is ideal for cosmetics, consumer electronics, pharmaceuticals, food packaging, stationery, and premium retail products requiring flawless shelf appeal.
Can this shrink film operate on high-speed automated packaging machines?
Yes. With its stable coefficient of friction (COF) and high seal strength (tested via ASTM F88), this film is specifically engineered for smooth feeding, rapid sealing, and minimal downtime on high-speed automatic packaging lines.
What is the optimal shrinking temperature range for this film?
The film begins free shrinkage at 100°C and achieves up to 81% shrinkage rate at 130°C. The recommended heat tunnel setting typically ranges between 110°C and 130°C depending on package size, speed, and gauge thickness.
Is Cross-linked POF film environmentally friendly and recyclable?
Yes. The polyolefin film is 100% recyclable, non-toxic, and free from harmful chlorine-based substances. Its lightweight structure also helps reduce overall carbon emissions and freight footprint.
What gauges (thicknesses) are available for customization?
Standard gauges include 12um, 15um, 19um, 25um, and 30um. Custom specifications and roll dimensions can be tailored according to your specific packaging machines and product requirements.
