How to control the physical mechanical properties of stretch film?
How to control the physical mechanical properties of stretch film? With the development of the logistics industry, stretch films have also been widely used. Stretch films are mainly used to stabilize, cover and protect products. The physical and mechanical properties of stretch films have been mentioned before, so let’s take a look below. How can we control it? The editor of Zhiteng stretch film manufacturer will introduce to you as follows: High transparency is conducive to the identification of goods; high longitudinal elongation is conducive to pre-stretching and saving material consumption; good puncture performance and transverse tear strength allow the stretched film to encounter sharp goods at high stretch magnification The corners or edges do not break; the high yield point makes the packaged goods more tight. The film produced by the casting method has high transparency, so it is not discussed here. As the number of C atoms of the comonomer of t...
