The difference between pure aluminium foil bags and aluminium plated bags
Aluminum foil bag packaging usually refers to the aluminum-plastic composite vacuum packaging bag, which is suitable for large precision machinery equipment, chemical raw materials, pharmaceutical intermediates moisture-proof, light avoidance, vacuum packaging. Three or four layers are adopted, and the utility model has the advantages of good water separation and oxygen separation function. Is not restricted, can bag quantity body is custom-built with different specifications, style, can be made into a bag, solid bag, organ bags, zipper bags and other styles. Products are subject to GB and ASTM standards, products comply with environmental requirements (can provide third party inspection report), products comply with the European Union and North America on the packaging materials the most stringent environmental standards.
Aluminum foil bags are divided into pure aluminum bags and aluminized bags, then how to distinguish between aluminum bags and pure aluminum bags in daily life? How many points are summarized?:First, from the material, pure aluminum bags are pure aluminum, high purity, is a soft material; aluminum plated bag mixed with composite materials, is brittle materials.Two, in terms of cost, the price of pure aluminum bags is higher than that of aluminized ones.
Three, from the performance point of view, pure aluminum bags moistureproof, cooling effect better than aluminum bag, pure aluminum bag completely avoid light, aluminized bag is shading effect.Four, from the use, the pure aluminum bag is more suitable for vacuum pumping, such as food, meat and other products, while the aluminum plated bag suitable for tea, powder, electronic and other pieces.Five, the inside of the bag facing the light or sunlight, can see through the bag of light is plated aluminum foil, invisible is pure aluminum foil
