Problems solved by technology

Single-layer polyethylene film has poor barrier properties to oxygen and other gases. When packaging fried foods and other foods, it is easy to cause contamination at the seal. General liquid packaging polyethylene film has poor sealing performance for this type of packaging and cannot meet the packaging process and requirements. The requirements for the storage period of packaging items, so it is necessary to use multi-layer polyethylene modified film or composite film with good barrier performance and inclusion sealing performance
