Physical and mechanical properties of plastic PET film-film supplier
Since the plastic film is subject to mechanical forces during printing and compounding, the film material must have a certain degree of mechanical strength and flexibility. The physical and mechanical properties of plastic film mainly include tensile strength, elongation at break, tear strength, impact strength, etc. In addition, the firmness of the aluminized layer on the aluminized film should also meet the requirements. Indicates the amount of water vapor transmitted by plastic film materials under certain conditions, such as the water per square meter of plastic film with a thickness of 25 μm in 24 hours at a relative humidity of 90% and a temperature of 30°C The quality of steam, to a certain extent, represents the moisture resistance of the film material. The moisture permeability of various film materials is different, which also determines its application range; the oxygen permeability of various film materials is also different.
