PE/PP Co-extruded Film Manufacturers

PE/PP co-extruded film is made of nylon + high-pressure polyethylene. It has good adhesion, is environmentally friendly and clean. It has excellent low temperature resistance, good chemical stability, and can resist the erosion of most acids and alkalis.PE/PP co-extruded film is a type of multi-layer film that is produced through a co-extrusion process, which involves extruding two different polymers, polyethylene (PE) and polypropylene (PP), together to create a single film with distinct layers. Each layer serves a specific purpose and offers different properties. PP (Polypropylene) Layer: Polypropylene is another thermoplastic polymer that offers strength, stiffness, and excellent chemical resistance. It is often used to enhance the film's mechanical properties, like tensile strength and impact resistance. The PP layer can serve as an outer layer or a layer that provides structural integrity and durability to the film.The combination of these two materials allows for a balance of properties, where PE provides sealing and moisture resistance, while PP enhances strength and mechanical properties. The specific application and properties of the co-extruded film can vary based on the requirements of the packaging or product it is intended for.

How does PE/PP Co-extruded Film achieve sealing and closure of emulsion explosive packaging?

PE/PP co-extruded film achieves sealing and sealing of emulsion explosive packaging through the following factors:
Material properties: PE (polyethylene) and PP (polypropylene) are both thermoplastic materials with excellent sealing properties. They have a lower melting point and can melt and fuse together under heat and pressure. This enables the film to form a stable and airtight seal when applied to emulsion explosive packaging.
Co-extrusion technology: Co-extrusion is a process in which multiple layers of different materials are extruded simultaneously to form a single layer of film. For PE/PP coextruded films used in explosive packaging, the film typically consists of multiple layers of PE and PP. The PE layer provides good heat sealing capabilities while the PP layer provides strength and durability. The polymerization of the two materials in the film allows for a strong seal and closure.
Heat sealing: PE/PP co-extruded films are usually packaged using heat sealing devices. When the film is placed over the packaging and heated, the PE layers melt and fuse together, creating a seal between the film and packaging. Heat sealing ensures a secure and tamper-proof seal, preventing leakage or contamination of the emulsion explosive.
Additional functions: PE/PP coextruded films often have additional functions to enhance the sealing and containment properties of emulsion explosive packaging. This may include antistatic agents or slip agents to improve handling and overall performance of the film during sealing of the system.
Emulsion Explosives Packaging PE/PP Co-extruded Film combines the sealing ability of PE with the strength and robustness of PP to achieve effective sealing of emulsion explosives packaging. The use of a co-extrusion process and a heat-sealing device ensures that the film forms a stable and air-tight seal, maintaining the integrity of the packaging and preventing any potential risks.
