CO2 lasers to achieve high-speed drilling on the packaging

Food packaging is often specifically designed structure, the purpose is to pass a moisture, oxygen or light to keep the product fresh. However, for consumers, sturdy, tightly sealed packaging may also be difficult to open. Therefore, sometimes the packaging manufacturers will scribe or punch holes in the packaging, making them easier to open. For a large number of ice cream cones manufacturers, now CO2 lasers have become high-speed precision punching indispensable packaging technology. Packaging challenge in this particular application, fill the cone ice cream cones are packaged in a material, this material is made from 70-80 micron thick sheet made of paper coated on one side with a layer of about an aluminum film 20 microns thick. In order to facilitate opening of the packaging, manufacturers punched through the paper layer while leaving the aluminum layer is completely not been touched. Reserved aluminum layer is required, it can maintain the stability of packaging machinery, while avoiding moisture and oxygen threatening to isolate packaging function. When a large-scale packaging manufacturers dessert initial development drilling process, clearly stated that any new approach should appeal to several important criteria. First, the drilling process must be able to be integrated with existing production lines together in the existing production line, box by the conveyor belt 3 per second transfer rate. Secondly, the drilling process should add only a very small unit cost to the product. Finally, this new process does not cause the paper discoloration or obvious debris, because it makes consumers of food have a negative experience. The package vendor immediately understand a conventional mechanical method does not meet all of these restrictions. In particular, none of the traditional paper cutting tools can accomplish this level of precision operations on the high-speed conveyor belt. So the company turned to laser systems development products - laser cleaning systems, to seek a solution. CO2 laser solution consists of laser cleaning system developed from the punching system will package a Coherent GEM-100 and focusing optics and two-dimensional galvanometer scanning system fit together tightly. GEM-100 is a continuous laser output power of 100W, while it is adjustable pulse width, 60% to 80% duty cycle of the pulse width modulation in order to create a dotted line in the product, rather than a continuous real scribing . In the processing chain, the paper is flat triangle. Laser cutting out a smooth curve, but with two additional "guides" (to help in the right spot at the start of precision tear) at each end of the line. Curve in this sheet is rolled into a final conical and cylindrical with a glue stick After this drilling formation becomes a straight line. Conveyor speed is about 1 m / sec and remains unchanged, the scanner will compensate for this movement, and cut when the product moving. Since the laser power is fixed (only laser duty cycle is varied, the peak power is constant), the scanning speed was the only variable effect. If you cut too deep or too shallow, you can change the scan speed to re-optimize the process.
