and PLA-coated paper cups and drinking straws from EcNow Tech and Shanghai Xinxin. Palsgaard says that all the polymer additives in
its Einar range are food-grade and food-approved – as they are sourced from sustainably produced vegetable oils.
Solutions on show at K2019 included anti-fogs and anti-statics. Its anti-fogs include Einar 1122, a water-based, solvent-free dispersion of food-grade additives. Ideal for stretched polyolefin and polyester films, it delivers anti-fogging performance at low coating concentrations and compares well with competing products, says the company. At the same time, its anti-statics include Einar
Derived from potato Kompuestos has developed a bioplastic made from potato starch that degrades in four weeks. The company says that the material, part of its
Biokomp range, aims to replace traditional super- market plastic bags for fruit or vegetables. This bioplastic, and three others in the range, have obtained the OK Compost label from TÜV Austria, to certify they are 100% biodegradable in a specific period. The four certificates obtained by the company
are divided into: two ‘OK Compost Home’ labels for bioplastics suitable for household composting; and two ‘OK Compost Industrial’ labels for those that are only degraded in industrial composting facilities. In order to be able to sell the products as
biodegradable or compostable, it is mandatory to obtain certificates accrediting the properties that are advertised, which may require between four and fourteen months depending on the level of compostability, said the company. Biokomp products are made from biodegrad-
able resins derived from different starches – from corn, potato and various cereals. The resins can be processed in standard processing equipment, as a drop-in for traditional petroleum-derived plastics. “Biokomp is a completely biodegradable and compostable alternative to traditional plastic,” said the company.
Adding value at K2019 At K2019, Total Corbion showed applications of its Luminy series of PLA bioplastics. A key focus of the display was its high heat resistant grades, which were demonstrated by serving hot drinks in thermo- formed Naturesse cups produced by Pacovis. Other exhibits included PLA-based Nespresso coffee capsules from ATI, thermoformed packaging items from Pack & Proper, Danone and Cuki Professional,

601, an amine-free solution for anti-static protec- tion in polyethylene (PE) applications. The company also showed Einar 201 – a gener- al-purpose mould release and de-nesting additive for PP applications – and dispersing aids including Einar 101, which disperses pigments more effec- tively than industry-standard waxes. “Anti-fogs, anti-statics and dispersing aids can be safe enough to eat,” said Christina Normann Christensen, product and application manager for non-food at Palsgaard. “Furthermore, using food-grade solutions doesn’t mean sacrificing on quality – in fact they commonly outperform fossil-based alternatives.”
