What is the air-thight?
The closed cell structure of the EPP, as well as ensuring excellent isothermal quality, it confers excellent insulating
qualities against odors and liquids. Nothing can go through the structure of the Polibox® containers, which, thanks
to the interlocking lids, they also are an excellent solution for large handlings. In case of Crystal containers, the
inner surface is "Crystallized", perfectly smooth and waterproof, compliant with law UNI 12571.
