CoolSeal's lightweight boxes are 100% recyclable and environmentally friendly.

We heat seal the edges in order to increase strength, improve insulation, eliminate potential contamination in open flutes, and to provide easy and efficient storage and transportation.

The strong, fiber-free packing boxes have an easy-to-erect design that ships flat, and compared to EPS they have similar internal volume with much smaller outer dimensions. The result is more pounds of product per pallet.



We manufacture standard leakproof boxes ranging in size from 5lb(3kg) to 50lb. Our standard leakproof box base has a ‘fold-over-end’ design making it completely watertight. An added benefit to a completely waterproof material with sealed edges that eliminates the risk of bacterial contamination in open flutes.

Certified for airfreight you can be sure your product will reach its destination by the fastest means possible in excellent condition. Your freight provider will no longer need to be concerned with leakage from your packages. Popular with any retailer interested in reducing waste disposal cost and supporting their Green initiative.
