Compostable, high-heat stable, food-contact safe, easy to process
During May 2019, nature2need launched its new bio-compound Bioblend LT25B, a cPLA that is compostable in industrial compost conditions according to EN 13432 (for Europe) and ASTM D 6400 (for North-America). The Bioblend grade is a blend of different bio-polymers, modified with mineral fillers. Main base polymer of the compound is PLA. The compound is very easy to process with industry-relevant cycle times on standard equipment and injection moulds. A quick, in-line annealing process, right after demoulding, is suitable to get all parts heat-stable up to 110 °C (HDT-B). nature2need´s right choice of different bio-polymers, natural additives that work as nucleating agents and natural, highly-effective compatibilizers guarantuee a quick and efficient material crystallization to meet high-heat requirements. The material is food-contact safe.
Bioblend LT25B targets to replace traditional, fossil-based plastics that are used in single-use and season-use items, like cutlery, food-containers, drinking cups, etc. Single-use applications made with non biodegradable materials are already or will be banned in a lot of countries very soon. There are a few alternatives to traditional, single-use or season-use plastics parts on the market, most of them are either very expensive or are not performing well. Especially thermal stability at temperatures around 70 – 100 °C is a problem with most of the eco-friendly alternatives. Products made with Bioblend LT25B compounds can be re-used a lot of times, a camping holiday or a season of dish-washer cycles are no problem, even for thin-walled parts.
“The spoons, knives and forks we molded with our material are sturdy, high-temperature resistant, they come with a surprisingly high perceived quality; bright-white with a very glossy surface. A much better product than the ones we all know made with traditional, oil-based plastics like PS. The cPLA material is completely compostable and – on top of this – offers significant reduction in carbon footprint.” says Dr. Karsten Brast, CEO of the nature2need Group. “Low cost and high-quality levels will make it easier to convince everybody out there to finally change to sustainable products!”
