Packaging must be as easy to open as possible, must satisfy the specific requirements of the product and must be appealing to the consumer.

Consumers are attaching increasing importance to packaging for high-quality snacks containing natural ingredients. Regardless of whether cheese or sausages are involved – the product packaging must be as easy to open as possible, must satisfy the specific requirements of the product and must be appealing to the consumer. For sausage snacks, packaging solutions are frequently employed that are based on PVdC. But now there is also a PVdC-free solution with easy opening, produced on the Poly-clip System Sealing and Clipping Machines.

But how do you snack on a clipped sausage? How do you get the sausage out of its skin without cutting the clip off? The sausage casing must be such that you can open it just with your hand. For this there are a number of approaches, which are frequently based on the use of PVdC. The disadvantage of these, however, is that PVdC plastics pollute the environment on both manufacture and disposal, and during waste incineration give off dioxins, which are injurious to health.

New packaging designs are based on the use of heat sealable composite films consisting of PE (polyethylene) and PA (polyamide). The PE outer layer with easy-peel is required for heat sealing with an overlapping seam. The inner PA layer provides the calibre stability. Easy opening is already allowed for in the manufacture of the flat film. For one thing, one edge of the flat film is provided at regular intervals with defined tear notches, which create tabs for tearing the film. Secondly, the plastic used must be oriented, so the film tears in a straight line around the sausage. Meanwhile, some film manufacturers already include composite films of this type in their product range.

The production of the new easy opening packaging on the TSCA 160/120 from Poly-clip System creates a win-win situation for manufacturers and consumers alike. Manufacturers can produce snack-type products with maximum cost efficiency and long-term security of investment. Consumers for their part get a product which contains no hidden risks, so they can ‘snack healthily’ as and when they please.
