How to distinguish between food aluminum foil bags or aluminized bags? Aluminum foil bags and aluminum-coated bags are different, as they all have aluminum components, but aluminum-coated bags are just a single layer of aluminum, while aluminum foil bags are made of pure aluminum, both in terms of production cost and selling price are far lower than Aluminum-coated bags are higher. Aluminum foil bags and aluminum-coated bags have different characteristics, feel and materials. They have their own characteristics and target customer groups. Aluminum-coated bags should be softer, while aluminum foil bags should be It is a bit harder, because the aluminum thickness of pure aluminum bags, that is, aluminum foil bags, is much higher than that of aluminum-plated bags.Aluminum-coated bag packaging usually refers to aluminum-plastic composite vacuum packaging bags. This type of product is suitable for moisture-proof, light-proof, and vacuum packaging of large precision mechanical equipment, chemical raw materials, and pharmaceutical intermediates. Three-layer or four-layer structure is mostly used, and the aluminum-coated bag has good water and oxygen barrier functions. There are no restrictions, and packaging bags of different specifications and styles can be customized, and can be made into flat bags, three-dimensional bags, organ bags, zipper bags and other styles. Aluminum-coated bags need to beGBandASTMProducts comply with environmental protection requirements(Third party inspection report available), The product complies with the most stringent environmental protection standards for packaging materials in the European Union and North America.Aluminum foil bags are divided into pure aluminum bags and aluminum-coated bags, so how to distinguish aluminum-coated bags and pure aluminum bags in daily life?1. In terms of materials, the pure aluminum bag is pure aluminum with high purity and is a soft material; the aluminum-plated bag is mixed with composite materials and is a brittle material.Second, in terms of cost, the price of pure aluminum bags is higher than that of aluminum-plated bags.3. From the performance point of view, the pure aluminum bag has better moisture resistance than the aluminum-plated bag. The pure aluminum bag is completely protected from light, and the aluminum-plated bag has a shading effect.4. In terms of use, pure aluminum bags are more suitable for vacuuming, such as cooked food, meat and other products, and aluminum-coated bags are suitable for tea, powder, electronic accessories, etc.5. Face the bag to the light or sunlight. The light that can be seen through the bag is aluminum foil, and the invisible is pure aluminum foil
