Saving the planet one pack at a time. Packaging that protects the planet and rids the planet of polystyrene.
Sustainable insulated packaging that replaces polystyrene
Designed to protect chilled and temperature-sensitive goods, Woolpack replaces expanded polystyrene with a circular, fibre-based alternative that performs across the cold chain.
Woolpack is Planet Protector Group’s high-performance insulated packaging made from 100% sheep wool sealed in food-grade film.
Independently tested for cold chain performance, WOOLPACK maintains stable internal temperatures while reducing environmental impact.

Awarded in the Packaging Materials and Components category, Lobster Protector is a breakthrough in sustainable seafood transport.
It is the world’s first fully plastic-free insulated shipper for live seafood, engineered to outperform EPS. A home-compostable wool liner provides reliable thermal performance, while the outer carton is made from 50% recycled corrugated fibreboard with a water-resistant, brandable finish.
A recyclable fibreboard insert manages moisture and CO₂ build-up to maintain carton strength during transit. Ventilation openings support airflow, and the liner is made from 100% sheep waste wool once destined for landfill, proving high performance and circular design can go hand in hand.
Recycling is simple with our program. You can return used packaging materials to us, and we will ensure they are processed responsibly. Visit our Recycle With Us page for more details.
Wool fibers effectively absorb moisture from the air, reducing humidity and condensation to maintain stable temperatures. Encased in a food-grade film, these fibers can breathe, creating a natural cooling system. When used with ice packs, Woolpack insulation has been proven to keep contents packed at 1°C chilled below 5°C for at least 48 hours. Pharma Protector and Pharma+ packaging have been scientifically proven to maintain pharmaceuticals within the critical 2°C – 8°C range for 24 to over 72 hours. Longer durations can be achieved with customized wool thicknesses and configurations.
After obtaining raw wool, it is naturally washed and scoured using only boiling hot water and soap. The wool is then manufactured into insulation material according to required specifications, cut into lengths, and sealed within recyclable or compostable film.
Yes, the natural washing and scouring process is free from chemical additives, ensuring the wool is sterilized without introducing toxic components. Sealing the liner inside recyclable or compostable film prevents fibers from contacting your products directly. There is no risk of Woolpack imparting a wool smell or tainting your products.
While Planet Protector has not conducted independent testing for frozen goods, multiple customers have tested and currently use the product for such purposes. As different products freeze differently, it’s recommended to conduct your own testing on samples before integrating Woolpack into your frozen supply chain.
Yes, wool’s elasticity and crimp factor provide cushioning and impact resistance, protecting goods during transit.
Yes, printing is available for the standard box range, allowing customers to incorporate their own branding. The minimum order quantity for printed boxes is 1,000 units. For smaller clients, using custom stickers on the unprinted portion of the standard box design is an alternative.
Woolpack cartons are delivered flat-packed. Liners arrive compressed in bundles; it’s recommended to open them one hour before packing to allow them to return to their original thickness. Deliveries are primarily sent on pallets, but small bundles can be couriered if preferred.
Yes, Planet Protector offers a Woolpack information flyer to educate your customers, explaining what Woolpack is and how to dispose of its components without using landfill.
The wool in Woolpack liners is cleaned of all contaminants with high-pressure hot water and soap and is encased in a food-grade film, so there are no biosecurity issues when shipping products in Woolpack. Generally, you do not need to declare the composition of your packaging, only the contents of what you are shipping. If concerned, it’s advisable to contact the destination country’s postal regulations directly before sending packages.
