How to prevent POF shrink film from aging? 

As a POF shrink film manufacturer, I'm here to teach you how to prevent the aging of POF shrink film. Please see below:

POF packaging film is necessary to participate in stabilizer in order to slow down the aging phenomenon. The first thing used to prevent thermal aging is called heat stabilizer. The first thing used to prevent oxidative aging is called antioxidant. What is primarily used to prevent photoaging is called light stabilizers, which are collectively referred to as stabilizers. Because of its high safety, it is especially used in food packaging and high-definition rigid polyethylene products. It is also widely used in plastic doors and windows, water supply pipes and decorative materials to replace other highly toxic plastic heat stabilizers.

The POF shrink film is white powder with amorphous structure, with low branching degree, relative density of about 1.4, glass transition temperature of 77~90℃, and initial decomposition at about 170℃. It has poor stability to light and heat. When exposed to sunlight for a long time above 100℃, it will decompose and attack hydrogen chloride, and further actively catalyze the decomposition, causing discoloration, and its physical and mechanical functions will also decrease sensitively. In practical application, it is necessary to take part in heating before stabilizing agent. POF packaging film is widely used. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials and fibers.
