Six popular foreign food packaging materials

At present, six more popular and promising food packaging materials are popular in the world.

First, high-temperature sterilization plastic tank: Material composition PP-EVOH-PP, which is characterized by the sandwich EVOH as a material, extremely good air retention, preservation period and the same canned, stored at room temperature for two years, can be used to replace the current metal tank . This material is in the trial production stage in the United States and Japan and has a patent.

Second, dual-use microwave ovens, ovens plastic tray: the crystalline PET as a material, can be high temperature, used for microwave ovens and oven foods, discarded after use. This material has developed rapidly in the United States and is currently used by 60% of households. Japan is also rapidly developing this material.

Third, the bottle can be squeezed: PP-EVOH-PP material, manufactured by co-extrusion technology, air retention, good extrusion, used for hot filling, non-sterile food packaging, if the sauce, sauce and so on.

Fourth, K-OAK hot filling system: material composition for the low density polyethylene paper - aluminum foil - containing the separation of polymer, hot filling method for high temperature filling and high acid food packaging, storage period of more than one year.
