What We Do


We have developed the technology to make sustainable plastic alternatives that you can trust, out of crustacean shell waste.

We are using our material to make sustainable packaging.

We had a passion for the plastic problem and felt that there was room in the market to offer a product that had not yet been done. In search of a product with a shorter breakdown time, we strayed away from what was already available. Our mission to find a more sustainable material base led us to crustacean shells, an abundant, nutrient rich waste source. Frozen food processing plants across the Asia-Pacific region cumulatively produce 8.1 million tons of crustacean waste per year, leading us to confidently say there is enough supply to meet growing demand.

This enabled Carapac to develop a packaging material derived from the chitosan contained in crustacean skeletons as a truly biodegradable alternative to plastic packaging. 

A packaging that fully breaks down within 90 days.



Carapac is focusing on fresh food packaging. The material has so many beneficial properties that can contribute to the plastic problem and food waste. 


As we developed our product, we spoke to 100s of farmers, horticultural groups, government representatives, and agricultural groups that exposed us to their struggles and shortcomings in the packaging market. 

Year on year Australia produces 4.1M plastic strawberry punnets alone.


As more and more people are hearing about us, we are receiving product requests from different industries.


From fresh food punnets, packaging pouches and clingwrap to requests such as cutlery bags, bin liners and poly bags.



Just when we thought we couldn’t love a bucket of prawns on a sunny day any more, we were wrong.

Waste Based

We aren't growing or producing a base material to produce Carapac. We are taking the waste from frozen food packaging plants and creating a product with many benefits.

Antifungal & Antibacterial

Crustacean shells embed anti-fungal properties, that when acting as packaging, prevent mould or fungi from growing on product.

Extends Fresh Food Shelf Life

Product shelf life can increase by up to 14 days depending on the product, having the potential to alleviate personal and commercial food waste

Shellfish Allergy Safe

The material is safe to use for those with a shellfish allergy as the protein component that causes the reaction is removed. ​


At the end of its packaging life cycle, Carapac products don't go into the trash. They can be planted right in your garden or pot plants and act as a slow release nitrogen fertilizer. Alternatively, they thrive in the green bin as well.

Ocean Safe

Should our material end up in the ocean, it will simply biodegrade within minutes. As it is made from a crustacean base and other natural additives, it does not harm animals should they ingest the material.


We call our material the first negative waste material, which is a step up from zero waste.

 We use a waste product and make it into valuable sustainable packaging and at the end of the packaging’s useful life one can use our material as a slow release fertiliser which is in itself valuable. Therefore we create a net negative waste in the overall waste system. and make a positive Impact in doing so.


Carapac products are not currently available for purchase yet but are working hard to get Carapac to you as soon as we can! 

We have spent the last year focusing on product development are scaling manufacturing. We are in conversations with manufacturers and will begin product testing over the next few months depending on the current global climate.
