Comparison Gorenje VS120W vs Sencor SVS 3010 GY

The width of the seam created by the vacuum sealer's welding slat.

The wider the seam, the more reliable the package is, the lower the likelihood that the welding line will turn out to be a “weak spot”. On the other hand, a large width requires a powerful heater and significantly affects the price of the device. In general, for domestic use, a value of 2 – 2.5 mm is considered quite sufficient; but in heavy industrial models used for long-term storage, values of 10 mm and even more can occur.

For additional reliability, the seam can be made double (see "Features").

Rated power consumption of the device. Usually, the characteristics indicate the average power in normal operation; peak values can be much higher, but this mode does not last long.

On the one hand, the efficiency and speed of vacuuming directly depend on the power consumption, on the other hand, the consumption of electricity. And heavy high consumption industrial-grade devices may require a three-phase connection (see "Power supply").

Special bags designed for single-use vacuum packaging of products. They are made from a multi-layer material, usually a combination of polyethylene and nylon, and come in various sizes (e.g., 15×20 cm, 20×30 cm, 25×35 cm, etc.). Disposable bags are suitable for packaging meat, fish, vegetables, fruits, bulk products, and prepared meals. Once sealed, the bag cannot be reused for vacuuming, as resealing compromises its airtightness and may lead to air leakage.

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.
