  • Master Batches Enable the Biopolymer Industry

    The bioplastics industry is highly dynamic. The more established biopolymers such as polylactic acid, thermoplastic starch blends and the polyhydroxyalkonoate family (which is still in its early days), have received significant interest. Although they are bio-based, much attention is focused on the compostability and biodegradation of these biopolymers.  [more]

  • Chain Extenders Improve Processing of PLA Biopolymers

    As the number of environmentally conscious consumers continue to grow into a transformative global force, the market demand for biopolymers also continues to increase. This, in turn, puts pressure on materials suppliers and processors to find ways to increase productivity and quality of biopolymer products, while simultaneously reducing scrap and cutting costs. Biopolymers can be easy to extrude and mold, but they are naturally low in melt strength, and are prone to degradation during processing. Recently, certain additives called chain extenders have been used successfully to improve rheological properties, and it looks like this technology can be used to help these remarkable polymers reach their full potential.  [more]

  • Rigid PLA Packaging for Meat Products

    Since the sizes of meat counters in self-service supermarkets have been reduced to an absolute minimum the distribution of meat and poultry, fish and several types of convenient-food are sold in plastic trays under modified atmosphere to give the products a longer shelflife. New systems of distribution made packaging of fresh food, and in particular the packaging of poultry, meat and meat products, fish, and dairy products an absolute necessity. The demand for transparent food trays took off when consumers accepted packaging as necessary part of the product to keep it fresh before distribution. For the last twenty years the distribution of most fresh products sold in self-service corners in supermarkets has been common in plastic trays with sealed lidding on the top and attached labels to give the buyer necessary information. Consumers never thought about differences in plastic, necessary barriers or other particularities because they bought convenience, freshness and products safely packed under best conditions. Up to now transparent PLA trays have been no more than a niche sector in the fresh food packaging business. [more]

  • Rigid Packaging Made From PLA

    An important field of applications for bioplastics is rigid packaging. This includes trays and punnets for fruit and vegetables, or for mince, fresh and cured meat. Clamshell or hinged containers are being used for deli-food products. Another interesting field of application is disposable tableware. “In addition there are more and more customers asking for bioplastic trays for other applications”, says Jhon Bollen from Nedupack. “Although most of the products we sell are for food applications.” Nedupack Thermoforming B.V. is a packaging producer in The Netherlands.  [more]
