Explanation of the Sealed Bag Industry

1. Sealed bags are very common in daily life and industrial production. They are made of various materials, such as polyethylene (PE), polypropylene (PP), etc. In daily life, common food sealed bags can effectively preserve food, prevent food from spoiling and getting a mixed taste; document sealed bags can protect important documents from dust and moisture. In the industrial field, sealed bags are also used to package electronic components, precision instruments, etc., playing the role of moisture-proof, dust-proof, and anti-oxidation. With the enhancement of environmental awareness, biodegradable sealed bags have gradually entered the market. Nowadays, the design of sealed bags is becoming more and more diverse, with different opening methods such as zipper type and press type to meet the needs of different users.

Ultrasonic welding installs the "twin engines" of efficiency and quality for the production of sealed bags.

2. Ultrasonic welding is an efficient connection technology that plays an important role in the production of sealed bags. This welding method is fast, has high strength, and the welded parts have good sealing performance. On the production line of sealed bags, ultrasonic welding equipment can quickly and accurately complete the welding process of sealed bags, greatly improving production efficiency. Moreover, no auxiliary materials such as glue are needed during the welding process, which is more environmentally friendly.
