Shrink packaging is a very common pack type, not only in food but in a vast range of products. Concerning food however, products such as agricultural or bakery can be easily and economically packed, with or without trays, with this method.
During the shrink packing process, film first creates a rather loose envelope around the product through thermosealing and then it shrinks undergoing a higher temperature.
In order though the above shrink pack be professional and attractive, shrink film should have some specific qualities.
Kapelis Packaging distributes shrink films produced by Syfan, a world class manufacturer in quite competitive prices! These films are certified for food contact polyolefins which, after the necessary process, can give a variety of characteristics, such as:
> Mono or multi-layered structure
> Antifogue properties
> Antistatic properties
> Hot needle perforation in order the venting holes not to widen during shrinkage
> Variable shrinkage power (‘weak’ or ‘strong’), according to product’s toughness
> Strong shrink memory (film continues to shrink after packing). It Concerns products that continue to lose volume, for example due to dehydration.
> Very good up to hermetic sealing
> Sealing even in relatively low temperatures (for sensitive products and/ or high packing speeds)
> Corona treatment to retain print ink
> “Heavy duty” films for heavy products that demand strong films
Offered shrink films are unanimus in their properties along their whole surface and towards all directions. This means uniformity of shrinkage along both film axes (machine direction and transversal direction), durability in fast machines and better sealing.
Furthermore, due to special irradiation, film molecules are cross-linked in most types giving stronger and non-seal burned films.
The above shrink films are delivered either single or center folded.
Kapelis Packaging also suggests the value for money shrink machines.
