CoolSeal Boxes

Utilizing state-of-art technology, our CoolSeal boxes and sheet goods are 100% sustainable and 100% recyclable.

The sealed edge technology that we utilize in our Seafood Cold Chain Packaging means its waterproof, hygienic and certified for direct food contact. Our packaging stands out from the competition for being lightweight, durable and robust. Our leakproof designs can withstand the volume of liquid and moisture from the seafood, keeping the product fresh and protected for longer periods of time.

3/4 Bushel Corrugated  Plastic Crop Boxes

Featured Product: CSA Produce Packaging

Our new produce packaging come standard, made with green polypropylene (PP5) and marked with smear-proof yellow UV ink. We hot air weld the box together and seal the edges for added durability, hygienics and insulation to keep your produce fresh!

The boxes are sold in bundles of 25, and are available in two convenient sizes: small (½ bushel) and large (¾ bushel.) As crop box manufactures we know the importance of efficiency, so we ship our CSA boxes flat for easy storage and include clear labeling for fast assembly in the field. Our CSA packaging is stackable, with locking tabs that universally fit both sizes, making for easy palletization.
