What is the difference between heat shrinking machine and vacuum packaging machine? Now let's analyze and discuss it! First, let's look at the different definitions of the two. The heat-shrinkable film packaging machine uses the shrinkable film to wrap the product or package outside, and after heating, the shrinkable film shrinks tightly to wrap the product or package, which can better display the appearance of the product, improve the exhibition performance of the product, and also increase its beauty and sense of value.

After being packaged by the heat shrinking packaging machine, the articles can be sealed, moisture-proof and pollution-proof, and can protect the goods from external impact, with a certain degree of cushioning. Especially when packaging fragile articles, it can prevent the containers from flying away when broken. In addition, it can reduce the possibility of products being dismantled and stolen.

Corresponding to the shrink packaging machine is the vacuum packaging machine, which includes: single-chamber, double-chamber, external extraction, inflatable and desktop vacuum packaging models. It is undeniable that vacuum packaging machines do have a trend of surpassing other similar packaging machines in some aspects, but all kinds of packaging equipment are actively innovative, and each machine has huge market potential. At present, China's packaging line still needs to rely on shrink packaging machines to achieve perfect "closure". The vacuum packaging machine can automatically draw out the air in the packaging bag and complete the sealing process after reaching the predetermined vacuum degree. It can also be refilled with nitrogen or other mixed gases, and then the sealing process is completed. Vacuum packaging machines are often used in the food industry, because after vacuum packaging, food can resist oxidation, thus achieving the purpose of long-term preservation.

Summary:

1. The heat shrinkable packaging machine is used to cover a layer of film on the outer packaging of the product to play a role of body-fitting beauty.

2. The vacuum packaging machine is used to pump out the air in the vacuum bag to keep fresh.
