biaxial stretching film
Molecular formula :
MW :
CAS :

nature : a specially treated plastic sheeting. The film is below the melting point, higher than the glass transition temperature, the thick film or films for vertical and horizontal two-way stretch, and then in a state of tension under heat treatment contraction stereotypes and the finished product. Stretch films are used to the raw material for polypropylene resins, polyethylene, polyamide, polyester, polystyrene, polyvinyl chloride, etc.. With BOPP film (BOPP), the largest output, with its transparent glass comparable, and with moisture, high mechanical strength, size and stability, light weight, non-toxic, printing or other good characteristics. Widely used in food, textiles, household goods packaging materials and composite film substrate, vacuum aluminum substrate, such as thin film capacitors.
