The key points of the design of laser adding an easy tear line on the biscuit packaging film roll

Packaging requirements: good barrier properties, strong shading, oil resistance, high strength, odorless and tasteless, and the packaging is scratchy.　　Design structure: BOPP/EXPE/VMPET/EXPE/S-CPP 　　Design reason: BOPP has good rigidity, good printability and low cost. VMPET has good barrier properties, prevents light, oxygen, and water. S-CPP has good low temperature heat sealability and oil resistance.　　In modern society, there are diversified consumer groups, as well as diversified consumer demands. For example, for people with obsessive-compulsive disorder, the tear of the product must be neat, otherwise it will explode in place, especially for people with super-severe obsessive-compulsive disorder. Therefore, in order to be more compatible with the user experience of consumers, more and more food, daily chemical, cosmetics and other industries will design easy tear lines/easy tears on the packaging of goods. When we go to supermarkets, convenience stores, etc. You can find it when you buy goods in retail locations.　　Manufacturing industry, especially machinery manufacturing, is a key industry related to the national economy and people’s livelihood. With the rapid development of laser technology, laser processing technology has become more and more widely used in the field of machinery manufacturing, becoming more and more important, and its influence is increasing. The application of laser technology in advanced manufacturing, such as rapid laser search, laser measurement, laser forming processing, welding, cutting, marking and heat treatment, will surely cause a comprehensive change in all fields of machinery manufacturing.　　 This device successfully applied laser technology to cut easy-tear lines on flexible packaging films. It can be installed on the slitter or rewinder. Utilize the functions of tension control, deviation correction, rewinding and unwinding of the slitter or rewinder; the beam generated by the laser will uniformly cut a thin line with a depth of only a few microns at the designed easy-to-tear line. So as to realize the easy-tear line on the roll film before bag making to destroy the outer film and retain the effect of blocking the inner film. It does not damage the air-tightness of the packaging material, but also has the function of regularly tearing the opening of the packaging bag in the specified direction when it is torn.　　 Label: Machine roll film
