How to choose the material for food packaging bags

耐低温性能：昆明食品塑料包装袋的外层通常采用具有耐低温性能的塑料，如聚乙烯（PE）或聚丙烯（PP）。这些塑料能够承受冷冻过程中产生的应力，保持结构和性能稳定。

Low temperature resistance: The outer layer of Kunming food plastic packaging bags is usually made of plastic with low temperature resistance, such as polyethylene (PE) or polypropylene (PP). These plastics can withstand the stress generated during the freezing process, maintaining structural and performance stability.
