The correct way to open the stretch film

No degumming is required. When the stretch wrap film is removed, no glue or traces remain on the surface of the processed glass product, which can maintain the product's smoothness and appearance. The strength and toughness of the stretch film is better, which means that the stretch film can withstand the impact force of 6-8 kg, otherwise it will break through the stretch film and break the processed object. It must also have proper viscosity, which can be adhered to and firmly adhered to the protected glass body, and the stretch wrap film can be smoothly removed after the processing is completed, so as not to increase unnecessary brittleness and tearing. trouble. PE stretch film is mainly blended and extruded from several different grades of polyolefin resin. It has puncture resistance, super strength and high performance. It wraps the goods stacked on the pallet to make the packaging more stable and tidy. Strong waterproof effect, is widely used in foreign trade, papermaking, hardware, plastic chemicals, building materials, food and medicine industries. The PE slit stretch film is made of high-quality LLDPE as the base material, do not add high-quality tackifiers, and is heated, extruded, cast, and then cooled by chill rolls. It has strong toughness and high elasticity. , Tear resistance, high viscosity, thin thickness, cold resistance, heat resistance, pressure resistance, dustproof, waterproof, single-sided adhesive and double-sided adhesive. The stickiness, tension retention, permanent deformation, elastic recovery, puncture resistance, etc. in the standard must use special tests, and they must meet the standard. Second, the stretch wrap film needs to have good transparency during use. When testing, the light transmittance and haze test methods of transparent plastics can be used. Third, in order to reflect whether the stretch stretch film can be used in shipping or in an environment with high humidity, and to protect the product from moisture or moisture absorption, it is necessary to ensure that its tightness after winding meets the requirements.
