What are the distinctive advantages of PE bagsPolyethylene is odorless, non-toxic, waxy-like, has excellent low temperature resistance (using temperature up to -70~-100℃), has good chemical stability, can withstand the corrosion of most acids and alkalis (not resistant to acids with oxidation properties), is insoluble in general solvents at room temperature, has low water absorption, and has excellent electrical insulation performance; but polyethylene is very sensitive to environmental stress (chemical and mechanical effects) and has poor thermal aging resistance.The properties of polyethylene vary by variety and mainly depend on the molecular structure and density. Different production methods can obtain products of different densities (0.91~0.96g/cm3).Polyethylene can be processed by the molding method of general thermoplastics.
In addition, the plastic wrap of PE material can also be called PE bags. Please note that the plastic wrap that is in direct contact with food must be made of PE material (in addition, it is generally PVC), which is safer for the human body.
Resolving method: The transparency, stretchability and viscosity of PVC plastic wrap are stronger than that of PE plastic wrap.When PVC plastic wrap is burned with fire, the flame will turn black and smoke will emit, and it will have a pungent smell, and will not drip oil. It will automatically go out after leaving the fire source.When PE plastic wrap burns, the flame is yellow, odorless, and will drip oil, and it can continue to burn after leaving the fire source.
PE bags are widely used in the packaging of: electronics, plastics, garments, toys, hardware products, and can serve as protection.
The surface avoids scratching.
1) When placing an order, if you install a light product, you can make it thinner, which can save costs;
If you install heavy products such as hardware, you should make them thicker, as thinner they will easily scratch.
2) If you want to inject the air hole, you must indicate the number of holes and the location of the holes to be drilled;
