Points for attention in selecting aluminum foil bags as high-temperature cooking bags
If you want to choose the aluminum foil bag as the high-temperature aluminum foil cooking bag, you should first choose the aluminum foil used in the cooking package, and pay attention to three points:1. The surface cleanliness of aluminum foil should be high, without oil and dust, and the surface tension should be high, which should reach more than 72mN/m. A simple method is to test with distilled water. The distilled water should be completely soaked on the surface of aluminum foil. If the surface of aluminum foil is heavily oiled, the composite fastness of aluminum foil and other materials will be affected, especially after the packaging bag is cooked at high temperature, delamination and peeling will occur.2. The number of pinholes in aluminum foil should be less. Aluminum foil should be a good barrier material, but if it has pinholes, its barrier will be greatly reduced. Gas and light will penetrate directly and quickly, and the content will soon deteriorate. Generally speakin...
