A clear understanding of their strengths and weaknesses can help you avoid significant losses resulting from choosing the wrong model.<br>Advantages of Nozzle-Type Sealing Machines<br>Purchasing Cost: Starting price is lower than that of chamber-type equipment 60%\u201385%<br>Portability: Can be placed on any flat surface for use; no permanent installation required<br>Suitable for large packaging bags: The packaging bag is placed outside the machine, so its size is not limited by the chamber; suitable for packaging bulk goods and large cuts of meat longer than 60 centimeters. Dry, hard goods: Nuts, grains, coffee, dried herbs, etc.\u2014products that can withstand external atmospheric pressure and are not prone to deformation.<br>Advantages of Chamber-Type Vacuum Machines (Unmatched by Nozzle-Type Models)<br>Liquid ingredients, marinades, and broths: Only chamber-type equipment may be used.<br>Maximum vacuum level: Chamber-type machines can consistently achieve \u201395 to \u201399 kPa; for nozzle-type machines, the maximum vacuum level is limited by the strength of the packaging film and is approximately \u201365 kPa.<br>Cost of packaging film consumables: Chamber-type machines can use standard, unembossed PA\/PE composite film; nozzle-type machines must use embossed or channel-patterned packaging bags with higher stiffness, resulting in a per-bag cost that is 30%\u201350% higher.<br>Operational Stability: The position of the nozzle insertion is affected by the operator\u2019s technique, resulting in inconsistent sealing results; the performance of chamber-type machines is not affected by variations in manual operation. Mass Production: With nozzle-type machines, the exhaust nozzle must be inserted manually for each cycle, making it difficult to achieve large-scale automated production.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1001\" height=\"345\" src=\"http:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-10.png\" alt=\"\" class=\"wp-image-5166\" style=\"aspect-ratio:2.901535395624802;width:778px;height:auto\" srcset=\"https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-10.png 1001w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-10-300x103.png 300w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-10-768x265.png 768w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-10-18x6.png 18w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-10-600x207.png 600w, https:\/\/www.ygpack.cn\/wp-content\/uploads\/2026\/05\/image-10-150x52.png 150w\" sizes=\"auto, (max-width: 1001px) 100vw, 1001px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Nozzle-Type External Vacuum Sealer (sometimes referred to as a tube-insertion vacuum sealer)<\/p>","protected":false},"author":1,"featured_media":5165,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[31],"tags":[],"class_list":["post-4139","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-faq"],"_links":{"self":[{"href":"https:\/\/www.ygpack.cn\/en\/wp-json\/wp\/v2\/posts\/4139","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ygpack.cn\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.ygpack.cn\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.ygpack.cn\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ygpack.cn\/en\/wp-json\/wp\/v2\/comments?post=4139"}],"version-history":[{"count":3,"href":"https:\/\/www.ygpack.cn\/en\/wp-json\/wp\/v2\/posts\/4139\/revisions"}],"predecessor-version":[{"id":5167,"href":"https:\/\/www.ygpack.cn\/en\/wp-json\/wp\/v2\/posts\/4139\/revisions\/5167"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.ygpack.cn\/en\/wp-json\/wp\/v2\/media\/5165"}],"wp:attachment":[{"href":"https:\/\/www.ygpack.cn\/en\/wp-json\/wp\/v2\/media?parent=4139"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.ygpack.cn\/en\/wp-json\/wp\/v2\/categories?post=4139"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.ygpack.cn\/en\/wp-json\/wp\/v2\/tags?post=4139"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
