Green Freshness / Hard Box
Send cooled goods greenly
With our plastic free fresh / hard box, we would like to help you bring your sustainable and environmentally conscious image to your customers' doorstep!
Our cellulose cold box is a sustainable, plastic-free, three-part system packaging with 100% cellulose insulation, which is fully and environmentally friendly 100% recycled in waste paper after use. At the same time, this environmentally friendly insulated box offers excellent insulating capabilities, is easy to handle, ecologically and practically superior to most alternatives - and is also very attractively priced. We have designed our green cooler for applications where a clean carton and quick, easy assembly of the insulated packaging are desired.
Accordingly, our Hard Box is an ecological refrigerated packaging that has been placed as a direct, sustainable alternative to the conventional Stryoporbox. With this insulated box, environmentally conscious senders of refrigerated products have the opportunity not only to conserve resources, but also to convey a green and ecological image - since the end customer sees directly that he has received packaging made of paper. The marketing effect can even be enhanced by printing on the carton or using paper tape with a company print. With different wall and insulation thicknesses as well as the use of cooling elements, you can ensure that both your chilled and frozen products arrive within the desired temperature window. We have been able to prove in various climate chamber tests as well as in practice that your chilled goods still arrive well chilled at the customer's even after more than 48 hours.
How do my cooled goods arrive safely?
With different wall and insulation thicknesses and the use of cooling elements, you can ensure that both your chilled and frozen products arrive within the desired temperature window. We have been able to prove in various climate chamber tests as well as in practice that your temperature-sensitive goods still arrive well cooled at the customer's even after more than 48 hours.
If you are interested in our sustainable insulation solution, we would be happy to support you with a test package - because temperature-sensitive goods have very different self-insulating properties due to different moisture content or material densities, for example, a test can help you make the right choice of insulation solution.
The experts at J.N. Lüning & Co. will be happy to advise you!
