The products of POF Manufacturer and other plastic products have same problem, that is aging. We can conduct a simple analysis of the aging mechanism of Polyolefin Shrink Film, try to avoid in use, make the polyolefin film get better use.
Because of the material of POF shrink film, the main chain of acrylic pressure sensitive adhesive is saturated chain. The general heat energy is difficult to break the main chain, the aging mechanism is mainly ultraviolet light aging, and the aging of substrate is mainly ultraviolet light aging. The show on the PE substrate at 80 DEG 30W under UV aging and tensile strength after 1 weeks of testing, the temperature has little effect on aging performance, and the ultraviolet light had great impact, but in the dual role of heat and ultraviolet light, the synergistic effects of aging.
Therefore, when using shrink film products, it is best to avoid high temperature, ultraviolet light, so that the use of shrink film can get better application effect.
