Lactips: French startup create milk protein-based plastic substitute for use in packaging

French startup Lactips has developed a plastic substitute in the form of pellets made from cow’s milk protein which can be used to make 100% natural packaging for detergents, and cleaning products.

The water-soluble thermoplastic pellets made from milk protein, casein, are fully biodegradable. The Saint-Étienne-based startup developed the pellets as a cleaner alternative to oil-based products.

Lactips aims to set up a new recycling industry for milk that is unfit for human consumption. As a cleaner industrial product, Lactips says it helps its customers to market less polluting products and help them reduce their environmental impact by no longer using petro-plastic.

The biodegradable pellets can be used by businesses to market green and better products like dishwasher or washing machine tabs, or chlorine tablets for swimming pools.

Although Lactips’ pellets are intended for use in manufacturing films to cover inedible products, the company is keen to work hand-in-hand with manufacturers to develop packaging for food packaging.

Lactips say: “Lactips provides a new and innovative technology that can be used to develop intelligent and edible packaging. Our products will be safer for consumers and better for the environment.”
