The Mecpack line of automatic "L"-sealers includes also some EXTRA-LARGE models, Mecpack BIG e Mecpack XL, that distinguish themselves for their state-of-the-art technology and for the high performances in any application fields with products of large size. They work full automatically: the only thing the operator has to do is just to put the products on the in-feed conveyor because a system of photocells controls the whole wrapping process by itself.
