The operator manually inserts the tube into the open bag opening and secures it, then starts the cycle; the machine first seals the bag by wrapping around the tube, and then retracts the tube. This is the most common design used in household and semi-industrial models.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Valve-type design<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The device does not come with a tube that can be inserted into the bag; instead, it features a recessed vacuum port on the body. When used with specialized vacuum bags equipped with one-way valves, simply align the valve on the bag with the port and press firmly to seal. The vacuum pump extracts air through the one-way valve, and the valve closes automatically when the bag is removed. If the bag features a combination of a zipper and a one-way valve, heat sealing is not required.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1005\" height=\"426\" src=\"http:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-12.png\" alt=\"\" class=\"wp-image-5170\" style=\"aspect-ratio:2.359291321253026;width:736px;height:auto\" srcset=\"https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-12.png 1005w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-12-300x127.png 300w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-12-768x326.png 768w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-12-18x8.png 18w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-12-600x254.png 600w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-12-150x64.png 150w\" sizes=\"auto, (max-width: 1005px) 100vw, 1005px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">YGPACK recommends: For commercial and food production applications, chamber-type machines outperform both types of nozzle-based models in terms of vacuum level, packaging material costs, and production capacity.
