BioPak have added a starch-based biodegradable packaging material to their portfolio of bioplastic options that provides manufacturers and brand owners the option of compostable packaging. The biodegradable packaging material is made from annually renewable resources.
BioPak have introduced a compostable extruded bioplastic sheet to the Australian market. These bioplastic sheets are manufactured from Bioplast GS2189, a blend of starch and PLA. Products made of Bioplast GS 2189 are completely biodegradable and compostable depending on their thickness.
The material is registered by DIN CERTCO to be biodegradable and non-toxic for the composting process (according to EN 13432). Depending on the duration and type of application, products made of Bioplast GS 2189 can be used for contact with food. All raw materials used for Bioplast GS 2189 are in compliance with relevant foodcontact directives. The bioplastic sheet is available in gauges ranging from 150 microns to 500 microns.
Recent trials using the Bioplast sheet on a Multivac form fill and seal machine, in combination with a heat sealed PLA lidding film, were successful. The compostable trays were blast frozen to minus 35 degrees Celsius without any sign of cracking or lid delaminating, a common problem with other materials.
The bioplastic sheet is:
- Completely biodegradable
- Has a rigidity comparable to PS
- Can be coloured with master batches
- Hot sealable
- RF sealable
- Has high surface gloss
- Non MAP meat and poultry trays
- Seafood trays
- Fruit and vegetable trays
- Yoghurt pots
- Seedling trays
- Business cards
- Access cards
- Point of sale displays
- Die cut boxes
- Vacuum formed packaging
