VMPET Extruding with PE
2024-10-11
The composite extrusion technology of VMPET (metallized polyester film) and PE (polyethylene) is a commonly used process in the manufacturing of packaging materials. The following is a detailed introduction to VMPET extrusion with PE:
1. Material characteristics
VMPET (Metallized Polyester Film): This is a thin film of metallic aluminum deposited on the surface of a polyester film using vacuum aluminum plating technology. It has excellent barrier properties, heat sealing properties, chemical resistance, and mechanical properties, and has a bright and beautiful appearance. It is widely used in packaging for industries such as food, medicine, and cosmetics.
PE (polyethylene): PE is a thermoplastic with good chemical stability, low temperature resistance, and processability. In the field of packaging, PE film is commonly used to make various packaging bags, containers, etc.
2. Composite extrusion technology
The composite extrusion of VMPET and PE is the process of co extruding two materials through an extruder to tightly bond them together. This composite film combines the barrier properties of VMPET and the processability of PE, and has a wider range of application prospects. Composite extrusion technology can ensure good adhesion between two materials and improve the overall performance of the product.
3. Application Fields
Food packaging: The composite film of VMPET and PE has good barrier and heat sealing properties, which can effectively protect food from external pollution and extend shelf life.
Pharmaceutical packaging: In the pharmaceutical field, this composite film is also commonly used to make packaging materials for drugs to ensure their stability and safety.
Other fields: In addition, the composite film of VMPET and PE can also be used for packaging in cosmetics, daily chemical products and other fields.
