Laser processing of tear lines on PE plastic packaging bags

With the popularity of plastic packaging, the market share of PE plastic packaging film continues to expand. Its products are widely used in industrial packaging (such as household appliances, machinery, chemicals, and building materials), packaging (such as corn stalks, silage alfalfa, etc.), and household and supermarket packaging (food, fruits, vegetables, etc.). It has the functions of protecting commodities, facilitating circulation, facilitating consumption, and promoting sales.

In today's society, consumer groups are diversified and consumer demands are diversified. For example, for patients with obsessive-compulsive disorder, items must be torn neatly, otherwise they will explode on the spot, especially for patients with extreme obsessive-compulsive disorder. Therefore, in order to better meet the consumer experience, more and more food, daily chemicals, cosmetics and other industries have designed easy-to-tear packaging on product packaging, which we can find when we go to supermarkets, convenience stores and other retail stores to buy things.

A new type of laser marking technology developed after the application of laser welding, laser heat treatment, laser cutting, laser drilling and other application technologies is a new type of marking method that is non-contact, pollution-free and wear-free.

Laser marking is a marking method that uses a high-energy density laser beam to act on the surface of an object, causing physical and chemical changes on the surface of the object to obtain a visible pattern. The high-energy laser is focused on the surface of the material, causing the material to evaporate rapidly and form pits. As the beam moves on the surface of the material, the laser is broken and processed into a pattern on the surface of the material by controlling the laser.
