Rolls
Rolls allow the user to independently cut bags of the desired length. They are often included in the delivery set of the vacuum sealer, especially in household and semi-professional models. The advantage of the roll is that it allows creating bags of any size — from small ones for spices to large ones for big pieces of meat or fish. Having them in the set allows you to start working immediately without the need to purchase separate bags.
Control
Control panel device of the vacuum sealer.
—
Button-based. A classic control system of the vacuum sealer using physical buttons on the body. This solution is considered reliable and intuitively understandable, especially for users who prefer simplicity and tactile feedback. Each function (vacuuming, sealing, stopping, etc.) has a separate button, which simplifies operation and reduces the likelihood of errors.
—
Touch-based. A modern format for controlling the vacuum sealer using a touch-sensitive panel. Instead of physical buttons, flat touch zones with backlight or pictograms are used. This interface makes the device more stylish, easy to clean, and modern in appearance.
Material
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.
