BIOPLASTICS
The company supplies biodegradable plastics, as well as plastics from renewable raw materials (bio-based plastics, even if they are not biodegradable).
Biodegradability is a material’s ability to break down through the action of microorganisms. The process and timescale depend on the material and environmental conditions.
Vilkritis can offer its customers all the types of bio-plastics listed in the table. After receiving a technical assignment from the customer and assessing the requirements of the individual project and the desired characteristics of the final product, the laboratory carries out tests and provides recommendations regarding the amount of colour concentrate, the temperature of the production process, and other parameters. Contact us for technical information and documentation for your selected raw material.

| Biodegradability | Non-bio-based (petroleum-based) | Partially bio-based | Bio-based |
|---|---|---|---|
| BIODEGRADABLE | PBAT, PCL, PBS, PES, PEA, PBSA, PVOH | Starch-based polymers, PBS, TPS, bio-based TPE | PLA, PHA, TPS, PBS |
| NON-BIODEGRADABLE | PE, PP, PA, PS, PET, PVC, PUR, PC, ABS, and others | Bio-derived PET, bio-based PC, bio-based PUR, bio-based TPE, bio-based copolyesters | Bio-based PE, bio-based PP, bio-based EVA, and others |
The table gives examples of plastics families. The proportion of bio-based raw materials and the biodegradation conditions depend on the specific grade, blend composition and product.
PLA
The bioplastics family includes PLA, PHA, TPS and PBS. PLA (polylactic acid) is a plastic produced from renewable plant-based raw materials and used in a range of products and manufacturing processes. Depending on the selected grade, PLA can be used for rotational moulding, film blowing, blow moulding, sheet and profile extrusion, injection moulding, film casting, foam sheet and film production, thermoforming, and fibre strip production. When selecting PLA for thin films or other products, the desired clarity, flexibility and strength are considered. When looking for a moisture-resistant plastic, it is important to assess the properties of the specific PLA grade and the conditions in which the product will be used.
