With an approximate volume of one million tons, shrink collation is the larger application field after stretch film. Its functionality is constantly evolving from the simple bundling media of the early application to more sophisticated three layer films permitting significant weight reduction. The downgauging trends of these films is remarkable: the industry use today a film more than 50% thinner than the one they used five years ago. The application is also rising the technical bar toward stiffer and optically improved features, as the bundle is becoming an instrumental communication vehicle, carrying the billboard effect to promote and give visibility to the product Brand.These development dynamics associated to the collation film industry proven to be the main drivers to the development of the P.O.D. line concept, five layer lines specifically engineered for high capacity non-barrier films.
