Expanded Polypropylene (PPE) boxes are transforming cold-chain shipping. Unlike disposable foam or cardboard, EPP is a super-tough, reusable foam. It bounces back from hits, stays insulating for years, and handles hundreds of shipments. For temperature-sensitive goods like vaccines or fresh seafood, this means fewer spoiled products, lower waste, and savings over time.
What Makes EPP Special?
EPP’s secret is its tiny air-trapping bubbles. This structure slows heat transfer both ways – keeping cold items cold and warm items stable. No chemical binders mean EPP is food-safe and odorless, ideal for sushi or medicines. It’s also ultra-lightweight, saving transport fuel and costs.
Built for Sustainability
A single EPP box replaces hundreds of single-use shippers, slashing landfill waste. When it finally wears out? It’s 100% recyclable into new boxes, with no downgrading. Plus, EPP uses eco-friendly blowing agents, helping brands hit green targets.
