Polyethylene film is also called pe film, which refers to a film produced with pe particles. It has moisture resistance and low moisture permeability. According to different manufacturing methods and control methods, products with different properties such as low density, medium density and high density polyethylene and cross-linked polyethylene can be manufactured.
Low-density polyethylene:
The density is about 0.92g/cubic centimeter. The low-density polyethylene film has good transparency and heat-seal performance, can be waterproof, moisture-proof, low tensile strength, high stretch rate, easy to wrinkle, film below 0.03mm, tension control It is small, and the tension in various places must be relatively constant, especially when heated, it is easier to deform, causing difficulty in color registration.
Medium density polyethylene:
Its density is about 0.93-0.94g/cubic centimeter, and its performance is between high density and low density polyethylene.
High-density polyethylene:
The density is between 0.94-0.965g/cm3. The heat resistance and mechanical strength of high-density polyethylene film is better than that of low-density polyethylene film. The stretch rate is relatively small. The thickness of the film is generally above 0.03mm, but the transparency is poor. , Adopting front printing, mainly suitable for vest bags, garbage bags and lining bags.
XLPE:
Compared with other polyethylene films, this pe film has higher heat resistance, tensile strength, heat shrinkage and barrier properties, and its use is further expanding.
Generally speaking, as the density increases, the mechanical properties and barrier properties will increase accordingly, and heat resistance is good. Polyethylene of the same density has different properties due to different film forming processes, and crystallinity Low, high transparency, low turbidity, but the molecular arrangement tends to be more irregular, so the barrier is small, the transmittance is large, the elongation is low, and the tear resistance is poor.
