Polyester high-pressure composite bags

If your food has frozen requirements, you can choose this product. PET has excellent physical and chemical properties, dimensional stability, transparency, and recyclability. It can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration, screen protection, optical grade mirror surface protection, and other fields. PE - Polyethylene. It is a thermoplastic resin obtained by polymerizing ethylene. Polyethylene is odorless, non-toxic, feels like wax, has excellent low-temperature resistance (can be used at temperatures as low as -100 to -70°C), good chemical stability, can withstand most acid and alkali erosion (not resistant to acids with oxidative properties). It is insoluble in general solvents at room temperature, has low water absorption, and excellent electrical insulation properties. Composite material vacuum bags are usually made up of multiple layers of different materials, such as nylon, polyester, polypropylene, etc. These materials are bonded together through adhesives or heat fusion technology to form a cohesive unit. The advantage of composite material vacuum bags lies in their excellent barrier performance, effectively isolating oxygen, moisture, and other external factors, thereby preserving the freshness and quality of the products. We control the details of our products from the choice of materials to the manufacturing details, such as edge banding tear notches. Customers can customize printed models or different sizes of products according to their own product needs. We offer the best options for the tightness and thickness of the product to keep food fresher and long time storage.
