Frequently Asked Questions
Q
What thickness options are available for Low Temperature POF shrink film?
Low Temperature POF shrink film is available in multiple gauge options: 12um, 15um, 19um, 25um, and 30um. Each thickness is designed to meet different packaging requirements, offering flexibility for various product sizes and protection levels.
Q
What is the shrinkage rate of Low Temperature POF film at different temperatures?
The free shrinkage rate varies by temperature. At 100℃, TD shrinkage is 38% and MD is 43%. At 110℃, TD is 52% and MD is 55%. At 120℃, TD is 64% and MD is 66%. At 130℃, TD reaches 71% and MD reaches 73%, providing excellent shrink performance across a wide temperature range.
Q
Is Low Temperature POF film compatible with all types of packaging machines?
Yes. Low Temperature POF film is suitable for use on any packing machine. Its wide shrinkage temperature range and excellent thermal sealing performance make it highly adaptable to both semi-automatic and fully automated packaging systems.
Q
How does Low Temperature POF film compare to standard POF shrink film in terms of optical performance?
Low Temperature POF film offers outstanding optical properties. For example, at 12um gauge, it achieves a clarity of 98.5%, a gloss of 88.0% at 45°, and a haze of only 2.1%. These values ensure high transparency and a premium visual appearance for packaged products.
Q
What industries can benefit from using Low Temperature POF shrink film?
Low Temperature POF shrink film is versatile and can be used across a wide range of industries, including food and beverage, cosmetics, pharmaceuticals, electronics, stationery, and consumer goods. Its clarity, seal strength, and low shrinkage force make it ideal for high-value retail packaging.
Q
What ASTM standards are used to test Low Temperature POF film properties?
The film is tested according to multiple ASTM standards: tensile and elongation properties are tested per ASTM D882; tear resistance per D1922; seal strength per F88; coefficient of friction per D1894; optical properties (haze, clarity, gloss) per D1003, D1746, and D2457; free shrinkage per D2732; and shrink tension per D2838.
