What are the performance requirements for high-temperature steaming bags?

We all know that high-temperature cooking bags are usually stored at room temperature and require a longer storage period, with a shelf life generally exceeding one year. Therefore, there are high requirements for the packaging and composite quality of these bags. In this way, the processing structure requirements for high-temperature cooking bags are relatively high. So, what are the basic processing structures?

Our factory's technical experts state that compared to general packaging bags, the main processing structures of high-temperature steaming bags are:

The basic processing structure of high-temperature cooking bags: According to the user's requirements, the type of contents, and the flow form, the product structure of high-temperature cooking bags is generally divided into three categories: two-layer film, three-layer film, and four layer film structures. The two-layer membrane is generally BOPA/CPP PET/CPP； The three-layer membrane structure consists of PET/AL/CPP BOPA/AL/CPP； The four layer membrane structure is PET/BOPA/AL/CPP, PET/AL/BOPA/CPP。 Therefore, his processing structure is very rich and can meet the needs of consumers for various products.
