Thermoforming / Rigid

Thermoforming / Rigid Packaging Trays from sugar cane waste Sugar cane by-product becomes raw material for biodegradable (fruit) trays Although environmentally friendly packaging for fruit and vegetable products is growing in popularity, its share of the total market is still relatively small. The most important reason for this is the fact that its price/quality ratio is not yet competitive enough to replace the traditional packaging that dominates the market. In an effort to package more fruit and vegetable products in planet-safer packaging, Bio4Pack has recently brought onto the market a new range of trays, which are primed to compete with traditional packaging. The new trays are based on a waste by-product: the cellulose fibres remaining after sugar cane processing. Package instead of burning The processing of sugar cane produces a relatively large quantity of waste by-product (approx. 40 % of the whole plant) which, until recently, was almost exclusively used as fuel for the sugar cane processing industry. Now, however, technological developments have given it a new future as the raw material for paper and cardboard. Bio4Pack (Rheine, Germany), a pioneer in environmentally friendly packaging for fruit and vegetable produce, seized this opportunity to develop a new series of trays, which serve as an alternative to paper pulp trays and disposable plastic trays. The new trays offer a number of important benefits compared to paper pulp trays. They are relatively cheap, in comparison with other green trays. Furthermore, the lower CO 2 emissions associated with their production process make them an ecologically more responsible option, compared to trays produced from paper pulp. The material properties of the sugar cane by-product make it possible to produce an end product that is not aesthetically inferior to packaging manufactured from traditional raw materials. The trays are smooth, retain their shape, ideal for presenting products and are highly resource efficient: unlike trays made from paper pulp, no trees need to be cut down to source the materials used for their production. Last but not least, the trays made from sugar cane byproduct are completely biodegradable, Home & Industrial compostable and they comply with the well-known EN 13432 standard for biodegradability. After use, they can be discarded in the biological waste bin, the paper recycling bin or on the compost heap. This completes the product’s life cycle with minimal harm to the environment, because the trays produce less waste and lower CO 2 emissions, in addition to providing fertiliser for new sugar cane plants. Hence, this latest compostable product from Bio4Pack is truly a circular economy-based green initiative. MT www.bio4pack.com 14 bioplastics MAGAZINE [02/17] Vol. 12

Thermoforming / Rigid Packaging Ultra-high barrier films for thermoforming Plantic Technologies Ltd (Altona, Victoria, Australia) has achieved a unique place in the world market for bioplastics through proprietary technology that delivers biodegradable and renewable sourced alternatives to conventional plastics based on corn and non-genetically modified cassava. Plantic’s thermoformable rigid bottom webs are providing a new class in ultra-high barrier films with added environmental benefits. Unlike other bioplastics companies who utilize organic materials but whose polymers are still developed in refineries, Plantic's polymer as well as its raw material, are grown in a field. The entire process integrates the science of organic innovation with commercial and industrial productivity in a new way. The result is both a broad range of immediate performance and cost advantages, and long-term environmental and sustainability benefits. Plantic has a stable range of products which include thermoformable rigid and semi rigid bottom webs, skin and flexible packaging materials these are currently in use by some of the world’s leading manufactures who are looking for ultra-high barrier material and to satisfy the growing trend of consumers who are aware of the impact of their actions on the environment. A further milestone for the Australian based company was achieved in 2016 when the PLANTIC R material was given approval to display the Australian Recycling Label from Planet Ark for recycling the first in the region for a multilayer structure. Plantic R uses Plantics core technology Plantic HP sandwiched between two layers of PET, the Plantic HP has a ultra-high barrier function which gives the complete pack an OTR of less than 0.05 cm 3 /m 2 /24h (@ 16°C, 1 atm - pure oxygen (50%RH)). Plantic is consistently monitoring the growing trend in bio based materials and will be releasing new products during 2017. Plantic staff will be available to discuss your needs at Interpack 2017, be on the Kuraray booth during the entire exhibition.
