Delivery inspection of high-temperature cooking bag (II)

When producing high-temperature cooking bags, in order to ensure the processing quality of high-temperature cooking bags, it is necessary not only to strictly control the production process, but also to ensure the safety of downstream customers. Therefore, inspection before delivery is essential. So what are the tests for high-temperature cooking bags before leaving the factory?

The technical experts of the high-temperature cooking bag manufacturer said that due to the limited experimental equipment of different manufacturers, the water vapor permeability, oxygen permeability, evaporation residue and other indicators were less tested, and the local quality inspection department was generally entrusted for quarterly supervision and inspection. However, the inspection items that can be done must be taken seriously, not only the product quality before cooking, but also the performance indicators after cooking.

The common test item is the test of peeling force, which is carried out according to the provisions of GB. The cut width is 15mm, the length is about 200mm, and the composite layer is pre-peeled for 50mm along the length direction. If the sample is not easy to peel, it can be soaked in ethyl acetate for about 20mm at one end, and still does not peel away from the base material, and the conclusion is that it cannot be peeled. During the test, the unstripped part and the tensile part are T-shaped, and the stable value during the stripping process is recorded. For BOPA, CPP and AL, the composite stripping force is greater than 4.5N. The combined peeling force of BOPA, AL and PET is greater than 3.5N. The peeling force drop after test cooking shall not exceed 1.0N.

The above is about the delivery inspection of high-temperature cooking bags. Jiangsu Genda Packaging Co., Ltd. specializes in producing various types of high-temperature cooking bags. If you plan to purchase, the quantity is large. After Z, I wish you all a happy life.
