Retort Canning Bags are stretched during processing. After the plastic is stretched, the strength can be increased accordingly, and a plastic material such as nylon or metallocene polyethylene can be added in the middle to make it have a composite strength exceeding that of a general plastic package. It does not have delamination peeling, good flexibility and excellent heat sealing performance.
