Tubeless vacuum sealers

Tubeless

— tubeless models of vacuum sealers do not come with their own product chamber; instead, the open edge of the package needs to be inserted into the device during operation. This tubeless design allows for smaller and more cost-effective vacuum packers. However, it is not as efficient in pumping air compared to chamber models and cannot facilitate packaging in a gaseous environment. Corrugated packaging bags are necessary for tubeless devices to prevent bending issues. Generally, tubeless models are primarily designed for domestic use and are not suitable for long-term food preservation through vacuum sealing.
