Our automatic vertical airless packaging machine is specially developed for liquid and viscous paste products. Different from conventional VFFS machines, it realizes airless packaging, leaving nearly zero air inside the finished pouch. Removing air from bags effectively slows down oxidation, greatly extending the shelf life of sauces, purees and fruit juices.
Equipped with matched rotary pump feeding system, this machine can stably feed high-viscosity materials like tomato paste and date paste without overflow. All material contact parts adopt food-grade 304 stainless steel, meeting food factory hygiene standards.
This airless packaging machine automatically completes film forming, airless filling, sealing and cutting in one continuous workflow. Operators can adjust filling volume, bag width and length easily on the touchscreen. It runs stably with low maintenance cost, perfect for medium & large food manufacturers who want longer shelf life for pouch-packed liquid and paste products.

✅ Application
✅ FAQ
- How does your airless packaging machine remove air inside the sauce pouch?
Our vertical airless filling & sealing structure eliminates trapped air during pouch forming and filling. Almost no air remains inside the finished bag, which prevents product oxidation.
- What shelf life improvement can I get with airless sauce packaging?
Without air inside pouches, oxidation is significantly reduced. Your paste or liquid products can achieve a much longer shelf life under the same storage condition, no need for extra preservatives.
- What types of material viscosity can this airless packaging machine handle?
It works for thin liquid such as fruit juice and high viscous paste including tomato paste, date paste, chili sauce and fruit puree. We can customize pump system according to your material.
- Can the airless function work for different pouch sizes?
Yes. Bag dimension is adjustable via touch screen. The airless packing feature remains effective when switching different bag sizes by changing forming mould.
- Is the machine food grade for sauce production?
All components touching the product are 304 stainless steel, fully compliant with food contact standards for food processing factories.
- Can I connect this airless packaging machine to my existing production line?
Yes. We customize pump pipeline and machine height to fit your factory’s current production layout.
- What is the production speed of this airless packaging machine?
Output depends on bag size and material property, ranging from 20–60 bags per minute. We will confirm the exact capacity after checking your product samples.
- Do you provide after-sales support for airless packaging equipment?
We offer 1-year machine warranty, lifetime online technical support, and video guidance for installation, commissioning and troubleshooting for overseas clients.
