2. products with high surface hardness: due to their high surface hardness and hard protrusions, such products as those with bone and bone products are easy to puncture the packaging bag during vacuuming and transportation. therefore, the packaging bag of such products needs to have good puncture resistance and cushioning performance. pet / pa / PE or opet / opa / CPP vacuum bag can be selected. If the weight of the product is less than 500 g, you can try to use an opa / opa / PE packaging bag. this kind of bag has good product adaptability and better vacuum pumping effect without changing the shape of the product.
3. perishable products: low-temperature meat products and other perishable products that require low-temperature sterilization do not have high requirements on the strength of the packaging bag, but require excellent barrier properties. therefore, pure coextruded films such as pa / PE / evoh / pa / PE films can be selected, or dry recovery methods such as pa / PE films can be used, and k coating materials can also be used. High temperature products can be made of PVDC shrink bags or dry compound bags.
4. higher grade and high quality products: the seven-layer coextruded package has better barrier performance and can meet the requirements of the products listed in 1, 2 and 3 at the same time. its use makes your products more elegant and greatly prolongs the shelf life of the contents.
