Thermal box liners
At Dufaylite, we might not be in the business of supplying outer box packaging, but we’ve got the inside covered (literally). Thermal box liners, crafted from paper honeycomb board, are the go-to primary packaging solution, designed to snugly fit inside a carton. They’re not just about fitting in; they excel at keeping goods cool, fresh, and in perfect condition during transit. With first-rate insulation and robust strength, these liners ensure products arrive just as they should – fresh, intact, and at the right temperature.
To learn more about the paper honeycomb board that makes these thermal box liners exceptional, check out the Envirolite page.

Envirolite: Packaging done differently
STEP 1
We’ll start with a friendly chat to understand your needs. We’ll discuss your current food packaging, specific temperature targets, timeline, budget, annual order volumes, whether you require chilled or frozen products, and box sizes and volumes. No lock-ins, no hard sell (our honeycomb does that for us).
STEP 2
Next, one of our ‘Dufayliters’ – our green gurus – will visit your site to clarify your requirements and review your current packing processes. We’ll even take away your existing packaging to create a bespoke solution tailored to your needs.
STEP 3
We’ll return with your newly designed internal box liners and ask you to re-pack your perishable items, including our thermal temperature gauge. You send this back to us, and we monitor the temperature throughout the delivery process.
STEP 4
Finally, we’ll re-visit you with a detailed report outlining the findings of our temperature trial test. This assesses the performance of our eco friendly box liners working with your product.
