Why use laser equipment in packaging production?

鈼廘asers used in the packaging industry are used to: 

鈼廝erforate plastic film or packaging.

鈼廋ut plastic film to slice or contour cut it.

鈼廝artially cut plastic film to create easy-to-open packaging.

Why laser perforation?

Laser perforation is the process of punching many small holes in a plastic film. The purposes of perforating a plastic film and then processing (converting) it into packaging are as follows:

鈼?Improved packaging performance breathability, as the packaging atmosphere can be controlled by regulating the gas exchange in the package.

鈼?Regulation can be used to improve the quality of the product and extend the shelf life of the product. Another application is the ability to compress large packages so that they occupy a smaller volume.

鈼廘aser is used to perform perforations due to its high precision and low setup costs. Costs can be reduced as no tools or any contact with the material that would cause wear are required.

The picture shows laser perforations of different hole sizes. From the smallest hole diameter of 0.076 mm to the largest of 0.378 mm

Easy to open packages with laser drilling

鈼?Providing easy-to-open packages is a competitive advantage. Using lasers, it is possible to achieve just the right processing depth in the package.

鈼?The ability to accurately determine the depth of the notch makes it possible to cut through certain layers in the laminate without the second layer being disturbed. The cutting can be done according to the respective package and purpose.
