What is the laser cutting process for PE bags/PE films?

PE heat shrink film is widely used in the whole-piece collective packaging of products such as tobacco and alcohol, cans, mineral water, various beverages, cloth, etc. It has the advantages of good flexibility, strong impact resistance and tear resistance, not easy to be damaged, not afraid of moisture, and large shrinkage rate. It is used to wrap the goods stacked on the pallet to make the packaging more stable and neat, and more waterproof. It is widely used in foreign trade export, papermaking, hardware, plastics, chemicals, building materials, food and medicine, and tobacco packaging industries.

Guangzhou Laisai Laser is an enterprise that proposes laser to replace mechanical processing technology in the film packaging industry. It is designed and developed specifically for film tear line and quantitative air permeability design. Compared with traditional mechanical gear punching, it is faster, the aperture and hole spacing are adjustable and more uniform, and it can realize the marking of tear holes (lines) in any direction and any shape. Laser technology is an instant high-temperature treatment that melts the area around the hole for protection, thus completely solving the problem of breakage after heat shrinkage. It also feels very smooth, giving customers a new sensory experience.
