Vacuum packing with laminated aluminum foil is often used for export purposes because it provides high protection for the product being shipped. Here are some reasons why:
Protection against moisture: Vacuum packing with laminated aluminum foil creates a barrier against moisture, which can cause damage or spoilage to certain products. The risk of moisture damage is greatly reduced by eliminating air and sealing the product.
Protection against oxygen: Oxygen can cause oxidation, which can damage certain products such as steel products, food, and pharmaceuticals. Vacuum packing with laminated aluminum foil reduces the amount of oxygen in the package, slowing the oxidation process.
Protection against the light: Some products are sensitive to light and can be damaged by exposure to UV rays. Laminated aluminum foil helps block out light, reducing the risk of damage.
Longer shelf life: By protecting the product against moisture, oxygen, and light, vacuum packing with laminated aluminum foil can help extend the product's shelf life. This can be particularly important for products that are being shipped long distances.
Overall, vacuum packing with laminated aluminum foil is a cost-effective way to protect products during shipping, reduce the risk of damage, and extend their shelf life. It is particularly useful for products that are sensitive to moisture, oxygen, or light.
