GB/T 33319-2016 Plastics—Polyethylene compounds for breathable film
Basic Information
Scope
This standard specifies the classification and naming, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of polyethylene (PE) breathable film special materials.
This standard applies to polyethylene breathable film special materials made from polyethylene resin as the base material, with the addition of mineral fillers and other additives, which are formed by melt blending. Note: The breathable film referred to in this standard is a film obtained by longitudinal stretching at a certain temperature after the polyethylene (PE) breathable film special materials are extruded and cast into film by a cast film extruder or blown into film. A certain number of micropores are formed inside it, enabling it to have a breathable function.
