What materials can be used to make holes in lasers?

One is a composite film, which is usually equipped with a one-way air valve or laser punching, and is mainly used for coffee bean packaging bags or microwave heating in food packaging (main functions: internal ventilation, ventilation, dehumidification, etc.).

The other is a single film, that is, a polyethylene breathable film, which makes full use of the breathable properties of polyethylene and is mainly used for beverage, fruit and vegetable packaging, etc. (Main function: Assisted by single film exhaust, it is beneficial to product shaping and ensure the beauty of the product)

The easy-tear line laser marking machine (easy-tear line laser marking machine) is a special equipment with ultra-fine air holes, which meets the requirements of dotted line holes, air holes, easy-tear openings, and heat-sealed laser marking. The minimum aperture is 0.1~0.3mm, which is effectively waterproof and breathable. It can achieve labels in any direction (not limited to straight lines) and any shape. It has the characteristics of high speed, stable performance, safety and reliability. It is generally used in conjunction with related equipment such as cutting machines, bag making machines, and hand-closing machines. In order to meet the needs of modern commodity packaging, it solves the shortcomings of traditional paper easy-tear lines, especially for the design of easy-tear quantitative air holes. The marking speed is fast, the equipment is easy to operate, the performance is stable, and the service life is long. Large aperture, small aperture, and uniform aperture can achieve tear marking in any direction and any shape.
