Advantages of laser die cutting machine in plastic film processing

Laser layer cutting refers to selectively cutting a certain film layer without affecting the functions of other film layers. For example, a certain degree of micro-cutting of the film layer can form an easy-to-open structure, but because the cut is small, it will not affect the appearance of the package. Although the mechanical scratching or mechanical punching method of plastic film is fast and fairly simple, these two methods cannot distinguish different film layers.

The results of mechanical scratching or mechanical punching are as follows:

鈶營f the scratch depth is too small, even the mechanical layer of the film cannot be completely divided;

鈶f the scratch depth is too large, the light-blocking layer and water vapor-blocking layer will be damaged. Therefore, people have been looking for a reliable processing technology that makes cutting more delicate and selective. It is optional to cut in different plastic film layers, which are all achieved by laser die cutting machines.

Easy-tear laser cutting machine is suitable for quantitative air permeable holes, easy-tear, heat-seal label laser labels in film industries such as food printing and packaging, beverage heat-seal labels, pharmaceutical outsourcing, daily cosmetics shrink film, etc. PE, PVC, PET, OPS and other film materials. It can be used with handheld devices, quality inspection machines, rewinding machines and other equipment.

鈶燯nlike mechanical processing methods, the laser does not directly contact the object during processing, so the article will not damage the object and the machine itself will not wear out. This non-contact processing method greatly improves the reliability during high-speed processing.

鈶he laser has the particularity and selectivity for the processing of different film materials, because the laser can cut without affecting other film layers, which greatly improves the safety of the product.

鈶here are two disadvantages of mechanical processing equipment that is easy to tear. First, it is very troublesome to frequently repair and replace molds, knives and maintenance rates. Secondly, the trend of the tear line after the customer tears it cannot be freely controlled. Many people easily tear the entire packaging bag when tearing, which is really a very bad user experience. But the layer cutting technology of the laser die cutting machine will not have the above situation. Our Laisei laser equipment can not only achieve the purpose of not destroying the packaging function, but also achieve the purpose of easy tearing. It is an easy-to-tear device.

CO2 one-to-two easy-tear line laser die-cutting machine, the equipment has no vibrating mirror structure, the light spot is finer, the light is continuously emitted, the efficiency is higher, and the speed is faster; it is suitable for the same-direction easy-tear line processing of single-layer and multi-layer film packaging. It is more convenient to cooperate with the production line structure.

In addition to being used as a shrink label, heat-shrinkable polyester film is also used for the outer packaging of daily necessities. Because it can not only protect the packaged items from impact, rain, moisture, and rust, but also win users through exquisite outer packaging, and also show the good image of the manufacturer. Nowadays, more and more packaging manufacturers use printed shrink film instead of traditional transparent film. Because printed shrink film can improve the appearance grade of the product, it is conducive to the advertising of the product, and can make the trademark brand leave a deep impression in the minds of consumers.

Laser technology is a new development in packaging technology in recent years. This new technology avoids the embarrassment of being unable to tear or leaking the entire torn content when tearing the package, making the application of flexible packaging more convenient. In addition, the dotted hole ventilation holes of laser die-cutting can adjust the aperture at will, and the direction and shape of the dotted hole can be set at will, especially for composite packaging of multi-layer materials, which can achieve semi-carving cutting, not only can realize the tearing function, but also can realize the waterproof and moisture-proof function.

Composite packaging bags often have better sealing, safety, light-shielding and anti-destruction properties for commodity packaging. Commodities using composite materials often have higher requirements for hygiene, temperature, humidity and light. However, the packaging of commodities must not only be "firm", but also consider the tearing property during use, so humanized tearing is very necessary. Composite packaging bags are easy to tear. Laser die-cutting and perforating machines can make dotted line perforations on one or more layers of composite packaging without destroying the integrity of the packaging's sealing properties. Laser perforation is difficult to achieve with traditional technology.
