Stretch film, also known as stretch film and wrapping film, is a commonly used packaging material:
Type
Transparent wrapping film Machine stretch film: Mainly used for automatic machine wrapping packaging, usually with high tensile strength and large width to meet the needs of high-speed packaging production lines. The thickness of machine stretch film is generally between 15-30 microns, and the stretch ratio can reach 200%-500%.
Industrial moving packaging wrapping film Hand stretch film: Suitable for manual wrapping packaging, with a relatively narrow width and a thickness generally between 10-20 microns. The stretch ratio of hand stretch film is usually between 150%-300%, which is convenient for manual operation and has good flexibility and self-adhesion.
Specifications
Rolling shutter shrink film Thickness: Common stretch film thickness ranges from 10-50 microns. The greater the thickness, the higher the strength and durability of the stretch film, but the cost also increases accordingly.
Rolling shutter shrink film Width:Transparent wrapping film The width is generally between 50-1500 mm. Stretch films of different widths are suitable for packaging items and packaging equipment of different sizes.
Length: The length usually ranges from 200 to 1000 meters. Long rolls of stretch film can reduce the number of times the film roll needs to be replaced and improve packaging efficiency.
Production process
Rolling shutter shrink film Blow molding: After the polyethylene raw material is heated and melted, it is extruded into a tube through an extruder, and then it is formed into a film by blowing and stretching. The stretch film produced by the blow molding method has good tensile properties and toughness, but the transparency is relatively low.
Transparent wrapping film Cast film method: The molten polyethylene raw material is cast onto a cooling roller through a cast film machine and quickly cooled and formed. The stretch film produced by the cast film method has high transparency and glossiness, good thickness uniformity, but relatively low tensile strength.
Features
High transparency: can clearly display the packaged items, easy to identify and view, make the packaging more beautiful and generous, and also facilitate the inventory and inspection of goods during storage and transportation.
