The focus application of easy-tear line laser scoring machine on plastic flexible packaging bags

Coptics Laser

Regarding the use of flexible plastic bags, what are the issues that consumers are most concerned about? The main focus of customer attention is whether it is easy to open ,why? First of all, since the flexible packaging bag is made of plastic film, plastic film has great elasticity and stretch properties,  it takes difficult to open. Secondly,  flexible packaging bags are widely used in the food industry. Some are  oil and seasonings, If you use too much force, the food will be taken out of the packaging bag, dirty consumers' hands, clothes, tables, floors, etc. Therefore, the opening of plastic flexible packaging bags has become a value-added point of product .



Installing laser equipment on the slitter or rewinder, and use laser technology to cut, scribe, perforate and layer-cut plastic film, aluminum foil, paper and other flexible packaging materials. Its processing method is to use the laser light beam to  draw a  line, dashed line, wavy line, and easy-to-tear line designed to be only a few microns depth on the packaging film.

Using the superiority of laser focusing, focusing can be as small as sub-micron, which has great advantages in the micro-processing of materials. When the laser energy is low, a higher energy density can be obtained, and the material can be processed efficiently.


The device successfully applies laser technology to flexible packaging film, which is easy to cut and tear. It can be installed on the slitter or rewinder. The system can realize the functions of cutting, coiling, coil tension control, deviation correction, retracting and unwinding, coiling and so on. 


Thus, the easy-tear line on the roll film before the bag is made, which destroys the outer film and retains the effect of blocking the inner film. This design does not damage the air-tight performance of the packaging material, but also has the function of regularly tearing the bag opening in the specified direction when it is torn.

Or adjust the output power of the system to control the cutting depth, and adjust the frequency to control the density of the dots to form dotted lines and dotted lines, which are easy to tear in straight lines. It is different from the appearance characteristics of other products and has a certain anti-counterfeiting effect.
