The difference between ordinary vacuum packaging bags and vacuum packaging bags that meet the requirements

Ordinary vacuum packaging bags and composite vacuum packaging bags are both packaging materials used to protect products such as food and medicine, and their differences mainly lie in materials and performance.
Ordinary vacuum packaging bags generally use single-layer plastic materials, such as polyethylene (PE), polypropylene (PP), etc., which have poor sealing and can only maintain a short-term vacuum effect. They are generally suitable for products with short storage periods and low preservation requirements, such as grilled skewers, sausages, or meat, seafood, etc. that require room temperature storage.
Composite vacuum packaging bags are usually made of composite film materials, which are diverse in materials such as polyester (PET), nylon (NY), aluminum foil, etc. The bonding and sealing properties of these materials are stronger than those of single plastic materials, and they can maintain a longer vacuum effect, which is beneficial for product preservation, moisture and oxygen resistance. They are suitable for application in more complex environments such as food processing, medical equipment, industrial products, etc. At the same time, composite vacuum packaging bags also have strong tear resistance, which can provide good protection for products.
In summary, composite vacuum packaging bags are stronger than ordinary vacuum packaging bags in terms of processing technology, material composition, and other aspects. They have more stable performance, longer shelf life, good moisture resistance, oxidation resistance, and other properties. However, the price of composite vacuum packaging bags is relatively high. Ordinary vacuum packaging bags are suitable for products that focus on low cost, have low requirements for storage time and preservation effect.
