Bubble bags are primarily made from high-pressure polyethylene bubble film through a cutting process, where the bubble film is cut to the required bag specifications and dimensions. They are then manufactured using specialized bubble film bag-making machines that employ heat sealing and cutting techniques. These bags are mainly used for cushioning packaging of electronic products, plastic products, metal products, ceramic products, glass products, and other items requiring protective cushioning during logistics and transportation. Currently, a variety of bubble bags are available on the market, such as kraft paper bubble bags and pearlescent film bubble bags.

Kraft paper bubble bags, also known as kraft paper envelope bags/courier bags, are made from kraft paper/PE. Their structure consists of an outer layer of kraft paper (white, colored, or natural) and an inner lining of bubble film.
Functions: The outer kraft paper layer (white, colored, or natural) has a smooth surface, making it easy to write on. It can be printed with different patterns, trademarks, and text according to customer requirements without infringing on intellectual property rights. The inner bubble film lining provides cushioning and shock absorption, protecting items from damage due to pressure, impact, or drops. No adhesives are used between the layers, making them completely harmless and environmentally friendly. The envelope opening features a self-adhesive strip design for safety and convenience.
Recommended uses: Mailing items such as CDs, DVDs, tapes, electronic components, integrated circuit boards, optical lenses, books, certificates, photo frames, gifts, watches, etc.
Pearlescent film bubble bags have an outer layer of pearlescent film and an inner lining of transparent PE bubbles, offering excellent cushioning and shock absorption to protect the contents from damage. The envelope opening comes with a self-adhesive strip, making packaging more time-efficient.
