Any product will have a certain service life, and it will appear on the day of aging, so this is only a matter of time, and if the early generation ages, the quality of the product will inevitably be affected to some extent, and the stretch film is the same. So in order to prevent this problem, we must use polyurethane. End this type of problem ahead of time. What is the basic phenomenon of aging when there is a problem?
The appearance of aging will vary depending on the raw materials produced by the stretch film. The aging is mainly caused by the pollution of light, heat, wind, rain and soil during use. As time goes by, it will change its structure and molecules, and thus aging. The appearance of the aged film is directly related to the raw material. After aging, the surface becomes viscous, hardened, embrittled, discolored, spots and colored, especially odorous. However, the appearance of the stretched film did not change much, but as time went by, the color became pale.
Stretch film Aging can seriously affect packaging and agricultural products, so the aging film must be replaced in time. Different types of resins and additives can be selected depending on the properties, shape and weight of the packaged goods. It can produce stretched films with different thicknesses, different shrinkage rates, different tensile strengths and different impact strengths, which fully meet the various requirements of commodity packaging.
Since the aging of the stretched film is the direct cause of the decrease in life, when we encounter problems, we must solve it in time, without delay. Of course, in order to avoid aging, we need to take precautionary measures in advance, which may affect the quality of the product. Avoid in advance.
