Wool fibres are incredibly effective at absorbing moisture from the air, which minimises humidity and condensation to maintain stable temperatures. The food grade film which the wool is enclosed in is microperforated to allow the wool fibres to breathe. This creates the natural cooling system. When used with ice packs to establish the required cool temperatures for packaging food, 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 keep pharmaceuticals within the critical 2°C - 8°C from 24 hours to more than 72 hours. Longer temperatures can be achieved with customised wool thicknesses and configurations. Please contact us for more information.
After the raw wool is obtained, it is naturally washed, scoured (using only boiling hot water and soap) and felted to make the insulation material to our required specifications. This liner is then cut into lengths and sealed within the recyclable or compostable food-grade wrap.
The natural washing and scouring process that we use is free from any chemical additives, ensuring that the wool is sterilised without introducing any toxic components to the product. Wrapping and sealing the liner inside a recyclable or compostable food grade wrap prevents the fibres coming into direct contact with your products. There is absolutely no danger that Woolpack will make your products smell like wool or taint any products in your carton!
Planet Protector is proud to offer a 100% Australia/New Zealand wool composition in all our products. The wool we recover is a waste product from the textile industry otherwise destined for landfill.
Woolpack wool is fire retardant. It will smoulder, not flame when exposed to fire.
Planet Protector has not performed independent testing for frozen goods. However, multiple customers have conducted their own testing and are currently using the product for frozen goods. As different products freeze differently depending on a number of factors, we highly suggest you do your own testing on samples prior to integrating it into your frozen supply chain.
Yes! Added benefits of wool are its elasticity and its crimp factor, which offer cushioning to goods in transit. It will provide crash protection to your packages.
The wool felt in Woolpack liners is cleaned of all contaminants with high-pressure hot water and soap (and encased in a food- grade film), so from a biosecurity standpoint, there are no issues with you sending your product in Woolpack. Generally, you do not need to declare the composition of your packaging, only the contents of what you are shipping. If you are still concerned about the postal regulations in the country to which you are shipping, we suggest you contact them directly prior to sending any packages.
Absolutely yes! We offer printing for our standard box range, which we find is the most accessible way for customers to incorporate their own branding into the package. Minimum order quantity for printed boxes is 1000 units. If you are a smaller client, another option is to procure your own sticker to put on our branded boxes. We have purposefully left the majority of the standard box design unprinted to allow for your own sticker branding to be added.
We are happy to provide you with a Woolpack informational flyer to educate your customers! This will explain to your clients what the Woolpack is and how to properly dispose of the components without using landfill.
Woolpack cartons come flat packed. Our liners arrive compressed in bundles, which you need to open one hour prior to your packing. This allows the liners to “bounce back” to their original thickness. We primarily send our items in pallets but can courier small bundles to you if you wish.
The gel solution is made from polyacrylate and sodium benzoate, and is non-toxic. This is safe to put down any domestic or commercial plumbing system with running water. The outer is a kerbside recyclable HDPE plastic suitable for any domestic or commercial recycling bins.
