Difference between packaging effect of vacuum packaging machine and shrinkage packaging effect
March 08, 2023
The vacuum packaging machine is a device specially designed for the food industry. It can vacuumize the products in the packaging bag and then inflate or directly seal the packaging. In recent years, with the development of industry, many products in other industries have also begun to use vacuum packaging machines to vacuumize some parts and components, and also use the principle of vacuumizing and blocking air to moistureproof their products.
Many customers can't clearly distinguish the vacuum packaging from the heat shrinkable packaging of the shrinking machine. It seems that they are all bag packaging machines. That's right. The shrinking machine is also a packaging process that uses the principle that the film shrinks when it meets the heat when the product is put into the shrinking machine after the film bag is made. The bag-making process at the front end can be realized by using automatic sealing and cutting machine, or manually bagging and then transporting to the shrinking machine for packaging. The shrinking machine can be used in combination with many automatic production lines such as sealing and cutting machines, and will play a powerful role in realizing modern production mode for enterprises. For the vacuum packaging machine, it can only be used alone and cannot be equipped with an assembly line. The front section can only be completed with manual assistance. The biggest difference is that the shrink machine can complete the packaging of the product after the bag is shrunk, but it does not have the function of vacuumizing. It can be a fully closed package or an open cuff package at both ends.
When purchasing vacuum packaging machines, customers should make clear the essential differences between the two equipment, and know the nature, size and packaging efficiency of their products.
