1. Precision Control: Laser perforation with tear lines ensures precise control over the position and shape of holes in packaging materials, suitable for products that require highly precise packaging.

2. Tearability: Laser perforation enhances the tearability of the material, making the packaging easy to open, providing convenience for users.

3. Efficient Production: Laser perforation is a relatively efficient processing method, capable of producing large quantities of perforated packaging in a short amount of time, improving production efficiency.

4. Personalized Design: Laser perforation with tear lines allows for personalized design, enabling the customization of holes with different shapes and patterns based on product requirements, enhancing the attractiveness of the packaging.

5. No Contamination: Compared to traditional perforation methods, laser perforation involves no physical contact or additional materials, avoiding the introduction of contaminants. This makes it suitable for applications where packaging hygiene is crucial.

In terms of applications, laser perforation with tear lines is commonly used in food packaging, pharmaceutical packaging, cosmetic packaging, and other fields. For example, it may be applied to beverage cans and pouch-packaged food in the food industry to improve packaging usability and market competitiveness.
