Compostable Metalised Laminate

Generally speaking, compostable materials are not compatible with wet or oily products over a long period. In certain applications they can work for products with short shelf-life requirements (~4-6 weeks).

No they don’t. Our materials are certified compostable which means that they’ve passed thorough biodegradation testing to ensure they completely biodegrade into healthy organic matter.

Compostable materials are designed to be composted and unfortunately that means they cannot be mechanically recycled. Although commercial composting systems are not currently widely available on a kerbside basis this is changing rapidly and so too is the rate of home composting.

Composting is an essential part of a functioning circular economy. We’ve broken down all the basics in our How to Compost blog post.

All of Swisspac’s compostable films and laminates are certified compostable, including any valves and zippers. For further information please visit our Certifications page.

The time it takes a product to biodegrade depends on the conditions of the composting environment. Industrial or commercial compost facilities run at higher temperatures and certification protocol requires materials to biodegrade within six months. Home composts are more variable and depend on external factors such as temperature, humidity and how often they’re turned. Home compost certification requires materials to biodegrade within 12 months at a temperature around 30°C. For more information check out our certifications page.

This is a great question and the answer is nuanced. They don’t contain plastic as most people know it but they are made from bioplastic, which is technically a type of plastic. Grounded has a range of bioplastics that are made using our compostable Plantmade™ technology.
