Recyclability and sustainability are important growing trends in consumer packaging. the desire for longer product shelf-life and support for recycling are two factors that drive these trends. When advanced packaging materials are used, packaging goes a long way towards meeting these desires.
One key supplier in the quest for recyclability is Klockner Pentaplast, which produce a rigid and flexible films portfolio that that are essential in protecting many products and brand identities in the food, beverage, and pharmaceutical sectors. German company Folienprint uses Klocker’s cost-effective eklipse shrink-label film which has a light transmission rate of under 1.00%. This protects the product, and has a high-shrink percentage that enables a more free design with contoured bottles and eliminates the need for high-barrier primary containers. Low-light transmission is very important because any ambient light, even display case lighting, can start to degrade photo-sensitive vitamins and proteins in products such as dairy, juice, coconut milk, and other beverages, reducing its shelf-life and creating potential adverse flavors.
Recyclers typically strive to attain high-PET container recycling yields, but many times shrink sleeves that cannot be adequately removed from PET flakes can contaminate recovered products and lower recycling yields.
Klockner’s Pentalabel ClearFloat is used by Folienprint, and with a density of 0.95%, ClearFloat shrink labels rise to the surface in a recycling float/sink separation tank. These films were engineered to meet guidelines set by the European PET Bottle Platform and the Association of Plastic Recyclers.
The properties of new families of films like these create increased recycling rate opportunities while at the same time allowing graphics that build brand appeal.
