Comparison Caso VC 350 vs Caso VC 300 Pro

The main material used in the construction of the body of vacuum sealer.

— Plastic. Plastic is inexpensive and quite practical, but noticeably inferior to metal in terms of strength, heat resistance and scratch resistance. Therefore, it is mainly used in devices that are not designed for large volumes of work and high loads — namely, manual and low-power desktop vacuum sealers.

— Metal. Metal cases are extremely strong and reliable, but they are more expensive and weigh more than plastic cases. Therefore, they are found mainly in powerful industrial models, for which strength and reliability are of decisive importance.

— Plastic / metal. Usually, in this case, plastic cases are meant, in which especially critical places are reinforced with metal inserts. This option is typical mainly for desktop models of intermediate and advanced levels. See above for details on plastic and metal; Here, we note that such a combination makes it possible to combine the advantages and, to some extent, mutually compensate for the shortcomings of both materials. So, the cases are not as expensive and heavy as all-metal ones, and at the same time more reliable than all-plastic ones.
