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 has an extensive rigid and flexible films portfolio that plays a major role in protecting many products and brand identities in the food, beverage, pharmaceutical, financial card, flooring, and industrial sectors. German company Folienprint uses Klocker’s cost-effective eklipse shrink-label film which has a light transmission rate of under 1.00%, which protects the product, and has a high-shrink percentage that enables freer design when using contoured bottles and eliminates the need for high-barrier primary containers. Low-light transmission is important because any ambient light, even display case lighting can begin to degrade photo-sensitive vitamins and proteins in products such as dairy, juice, coconut milk, and other beverages.
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 technical properties of new families of films like these create opportunities for increased recycling rates while at the same time allowing graphics that build brand appeal.
