Recycled Wool Fiber Core with Food-Safe Biodegradable Cover

Flat-packed, compressed delivery

Our insulation liners and pouches are supplied flat-packed, resulting in significant savings in storage, handling, and transport when compared to the same volume of polystyrene boxes. Additionally, the recycled wool insulation core is delivered in a compressed format, minimizing warehouse footprint and reducing inbound logistics cost.

Unlike polystyrene, which is restricted to fixed dimensions and limited performance profiles, Fandaro’s home-compostable wool insulation can be custom-cut to fit your specific box formats and temperature requirements. This ensures precise thermal performance, reduced shipping waste, and optimized packing efficiency across your cold-chain workflow.

Flexible Packaging Options

How to use:
Place one liner to cover the base, one side and top of your box, place the other liner to cover three sides of your box. Add your products and cooling elements, then fold the liner over the top before sealing the carton. This creates a continuous insulated barrier, helping maintain temperature and providing impact protection throughout transit.

Our insulation liners can be purchased individually or as part of a complete packaging system, including home-compostable insulated pouches. We offer a range of standardized sizes and custom-cut solutions to support both growing and established businesses.

Biodegradable Recycled Wool Insulation Liners

What makes our insulation linings sustainable?

Our insulation liners are produced by mechanically recycling clean, unused wool fibers sourced from the textile and apparel supply chain. During processing, the fibers are carded into a lofty, lightweight batt containing micro air pockets that deliver excellent thermal and acoustic insulation.

The manufacturing process requires very low energy, making the material significantly more sustainable than conventional cold-chain packaging. Instead of producing insulation from new raw materials such as polystyrene or petrochemical foams, we upcycle wool fibers that would otherwise be discarded as industrial waste.

By transforming under-utilized natural fibers into 100% home-compostable insulated packaging, we reduce reliance on scarce virgin resources and help keep valuable textile materials circulating within the economy, rather than sending them to landfill.

Packaging insulation for time-temperature sensitive goods

Our insulation liners and pallet covers provide protection from temperature fluctuations and external damage when it is necessary to maintain a constant temperature during shipment. Parcel sending is more popular than ever before. With our 24+ hour upcycled wool box insulation linings you can send frozen food, petfood, pharmaceuticals or any chilled product to your customers with any standard parcel delivery service at an all time low cost.

Recycled Natural Fiber Insulation

All of our insulation liners are made from recycled wool fibers, ensuring that no virgin materials are required in production. By upcycling high-quality fiber offcuts from the textile and apparel industry, we prevent valuable natural materials from being sent to landfill and extend their useful life in a high-performance application.

The liners are enclosed in a biodegradable, food-safe protective film, making the entire product 100% home-compostable after use. This design eliminates the need for polystyrene and other petrochemical-based plastics, while delivering stable, natural thermal performance for cold-chain shipping.

Many customers choose to reuse the liners before composting — for insulating plants in winter, lining pet beds, protecting stored items, or other practical household and workshop uses. We also encourage the donation of used liners to local animal shelters, where wool provides excellent warmth and comfort.

Our recycling and forming processes require very low energy and we do not use synthetic binders, resins, or petrochemical adhesives. By choosing Fandaro, you help reduce textile waste, lower supply chain impact, and replace single-use plastic packaging with a circular, biodegradable alternative.

INVESTMENT IN SUSTAINABILITY

Circular economy

Cost-effective parcel insulation

By choosing our home-compostable insulation liners made from recycled wool fibers, your company directly reduces reliance on petrochemical-based packaging and helps prevent valuable textile materials from being discarded as waste. Instead of ending up in landfill, these fibers are reintroduced into a functional, high-performance application, extending their useful life and supporting a more circular packaging system.

Cost-effective parcel insulation

Unlike rigid foam packaging, wool insulation actively regulates humidity and slows thermal exchange, creating a stable micro-climate inside the package. This means temperature changes happen gradually, providing valuable buffer time during courier handling, transport delays, or doorstep waiting.

The natural loft and resilience of the wool fiber batt also provides built-in shock absorption, reducing the risk of bruising, crushing, or surface damage to packaged products — particularly fruit, delicate cuts of meat, prepared meals, and pharmaceutical cartons.

The liners maintain their insulating performance even when exposed to moisture or condensation, unlike paper-only or cellulose-based alternatives that lose efficiency when damp. This makes them particularly suitable for frozen shipments and long-duration cold-chain routes.

Packaging and delivery

Eco-friendly Recycled Nonwovens

We supply our recycled wool insulation liners in compressed, flat-packed bundles, delivered across the EU and the UK. This packing format significantly reduces inbound transport volume, meaning more units per pallet and fewer shipments required.

Flat-packed storage also allows your facility to hold larger quantities in less space, improving warehouse efficiency and ensuring packing materials are available on demand, without interrupting fulfillment operations. Compared to rigid foam packaging, our liners minimize both storage footprint and handling effort, reducing overall logistics cost and carbon impact across your supply chain.

Eco-friendly Recycled Nonwovens

We mechanically recycle clean, unused wool fibers and form them into a stable nonwoven insulation batt within a single integrated production process. This allows us to control density, loft, thermal resistance, and material consistency batch after batch — ensuring reliable performance in real cold-chain logistics environments.

While sustainability is a key advantage, the primary value of our insulation lies in its functional performance: wool fibers naturally retain insulation even under moisture, provide gradual thermal buffering during transit, and offer built-in impact cushioning to protect delicate products.

Innovative packaging must perform, not just claim to be green. Our home-compostable wool insulation is engineered for thermal stability, durability, and moisture resilience, helping ensure products arrive fresh, safe, and intact, regardless of the shipping conditions.
