GB/T 19787-2025 "Encasement material, polyolefin thermal cissing film"

GB/T 19787-2025 is a national standard for polyolefin thermal cissing films. It stipulates the classification, requirements, test methods and inspection rules of thermal cissing films made of polyethylene (PE) and polypropylene (PP) through biaxial stretching. The standard specifies the specific indicators of key physical and Mechanical Properties such as Appearance, Dimensional deviation, tensile strength, fracture elongation, tear resistance, thermal cissing rate, etc., and distinguishes according to thickness and type (ordinary type/crosslinking type), which is the authoritative technical basis for guiding its production, inspection and acceptance.
