Transparent Vacuum Plastic Sealer Pack Bag

In the packaging field, our PA/RCPP composite flexible packaging is initiating a revolution. Polyamide (PA) and cast polypropylene (RCPP) collaborate to construct a packaging system that transcends tradition.

The PA layer, like a loyal guardian, relies on top – notch barrier technology to keep oxygen, water vapor, and odors at bay. For food products, this means that delicious flavors can be maintained on the shelves for a long time. For example, in meat packaging, it can effectively inhibit fat oxidation and maintain the freshness of the meat. Moreover, the strong mechanical strength and puncture resistance of PA are sufficient to withstand the bumps and collisions during transportation. Even after a long journey, the products can remain intact.

The RCPP layer endows the packaging with flexibility. Its soft texture enables the packaging to closely fit various oddly – shaped products, just like a tailor – made “skin” for the products, greatly improving packaging efficiency. In the heat – sealing process, the advantages of RCPP are fully demonstrated. It can form a firm seal in a short time, eliminating the risk of leakage. Besides, its chemical stability builds a solid defense line for product safety, and there will be no adverse reactions when in contact with products. Additionally, RCPP has an outstanding feature of high – temperature resistance for cooking. In high – temperature cooking environments, RCPP can stably maintain its structure and performance without deformation or rupture. This characteristic makes the PA/RCPP composite flexible packaging an ideal choice for high – temperature sterilized food packaging, such as various canned foods and ready – to – eat dishes that require high – temperature cooking. After high – temperature cooking, the packaging remains intact, effectively isolating external pollution and retaining the nutrition and flavor of the food to the greatest extent.
