Sustainable materials for injection molding

Sulapac materials for injection molding are sustainable alternatives for PS, ABS, PC and PP. They can be used for various applications including cosmetic packaging, kitchenware, and cutlery.

To maximise the functionality of your end product, there’s a range of material grades you can choose from with different flexural and tensile properties, heat resistance and density. In terms of look & feel, you can opt for a natural appearance with large wood chips or a smooth polished surface, or something in between!
