In many European countries, resealable flow packs have been a preferred packaging concept for sliced meat, sausage and cheese products for many years. In Germany as well, the relevance of flow packs is steadily growing in many fields of application. This includes the packaging of salad, baked goods, cereal, snacks, sausages, frozen fish and shellfish – and most re-cently, even ground meat. Consumers respond positively to the material-efficient and lightweight bags, which is why many manufacturers and packers are considering this packaging concept more and more as an alter-native.
And for this packaging system as well, the demand for recyclable alterna-tives is also on the rise. It is particularly concepts based on polymers that are classified as recyclable and can be returned to existing material streams that are now receiving an increasing amount of attention.
A powerful film portfolio “on the cutting edge”The solution provider of choice and the first point of contact when it comes to high-performance films for the food industry is Südpack. The leading film manufacturer already offers an extensive range of high-performance structures that are individually designed to meet the requirements of the product to be packaged as well as the packaging technology in use. The best example is the innovative product family Pure-Line, which in addition to re-cyclable mono-materials based on PP, now also includes solutions made of PE. Depending on the products to be packaged, the high-performance films can be equipped with different barrier properties in order to provide opti-mal product protection. Despite their reduced material thickness, flow packs based on Pure-Line films provide a high level of stability that is compa-rable to conventional packaging systems.
The Pure-Line films have been tested on horizontal and vertical flow pack lines from the leading manufacturers of packaging machines. They have also been specifically designed for high output rates and maximum material yield. Moreover, the films are distinguished by a broad sealing range, which results in a high level of process and packaging safety. At the same time, the formation of a sealing layer ensures the simple and efficient in-line applica-tion of common zipper systems.
