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.
Trapped air is the key. Air is trapped in the flutes with our Heat Sealing Technology, this manufacturing process allows us to seal the material and trap the cool air inside, making it a stronger, leakproof package with improved insulating properties.
The plastic corrugated material we use is lightweight and is strengthened through the process of heat sealing the edges.
This trapped air in the tray and the lid improves the insulating properties of the package by restricting the flow of temperature. Each CoolSeal box surrounds it's contents with a wall of trapped air for insulation and strength.
