specializing in the production of stretch film, adhesive tape, packing tape, etc
Stretch wrapping film is widely used in life, and uses high-performance resins and accessories. Generally speaking, the stretch film produced by Tongling Xinnuo Packaging Factory, under normal temperature conditions, uses the mechanical stretching device or the deformation stress generated by forcibly stretching the machine stretch film by hand to wrap the goods tightly to facilitate transportation. A form of packaging for storage.
Stretch film is a very popular form of packaging internationally. In the manufacturing process, the stretch film is extruded with imported resin and advanced cast film. The stretch wrap film has the characteristics of excellent tensile properties, tear resistance, strong penetration resistance, high transparency, good self-adhesive properties, high retraction rate, tight packaging, and no looseness. It can be widely used in chemical raw materials, food, mechanical and electrical products, light textile products and other single items or on pallet packaging and other bundled packaging.
When the stretch wrap film is used, how to cut the stretch wrap film has also become an aspect that everyone pays attention to. First of all, sawing can be divided into manual sawing and sawing machine cutting. The main tool for manual sawing is a manual hacksaw. There are two types of hacksaws: movable and fixed, both of which are composed of a saw bow and a saw blade.
After that, the pressure test of the wrapping film mainly includes the pressure test of the film product and the pressure test of the membrane channel system. The pressure test of the film product is to check the compressive strength and tightness of the film product itself, usually based on the nominal pressure of the corresponding film product. The multiple or the specified value corresponding to the membrane channel grade and membrane diameter is used as the test face pressure value. Finally, we should also pay attention to checking the compressive strength and tightness of various interfaces after various membrane products are formed into a system by various connection methods.
