Difference Between Pognova Tabletop Vacuum Sealer EV20 EV30
The primary differences between the EV20 and EV30 desktop vacuum packaging machines lie in their sealing bar length, pump displacement, and electrical power. The EV30 outperforms the EV20 in all these parameters, featuring a 300mm sealing length as well as greater displacement and power output. Consequently, it offers superior vacuuming speed and accommodates a wider range of material sizes.

About Pognova Tabletop Vacuum Sealer EV20
The EV20 desktop vacuum packaging machine features a more compact design—smaller in both physical dimensions and weight. It accommodates sealing lengths of up to 250 mm and is equipped with a vacuum pump with an exhaust capacity of 4 m³/h. Compared to the EV30 model, it is better suited for smaller items and offers a slightly slower evacuation speed. Nevertheless, it delivers exceptional performance in terms of both sealing quality and vacuum level; while its specifications are relatively more modest, it offers superior value for money.
About Pognova Tabletop Vacuum Sealer EV30
The EV30 is another desktop-style vacuum packaging machine, featuring a larger physical footprint. Compared to the EV20, it offers enhanced performance capabilities; it accommodates sealing lengths of up to 300mm and boasts a pump displacement of 9 m³/h. Consequently, it supports a broader range of materials and delivers superior operational speed.
How To Choose The Right Model For You
First, you need to determine which sealing length range is suitable for the dimensions of the materials you typically package. Additionally, you must clarify whether you have specific requirements regarding packaging speed. After evaluating these key factors, you should select the appropriate machine model based on your budget. If you handle a wide variety of materials and have significant volume requirements, you should opt for the EV30; conversely, if your needs are more modest, the EV20 would be the suitable choice.

Suitable for use with flexible packaging materials such as composite films or aluminum-plastic laminates. It is designed for the vacuum packaging of solid, liquid, powdery, or paste-like items, including grains, food products, fruits, seeds, pharmaceuticals, chemical products, electronic components, precision instruments, and rare or precious metals. Once packaged, products are protected against oxidation, mold, insect infestation, spoilage, and moisture ingress; this preserves their quality and freshness, thereby extending their shelf life.
Generally, vacuum sealing can extend the shelf life of food by 3 to 5 times compared to conventional storage methods like plastic bags or containers. By removing oxygen, the machine inhibits the growth of aerobic bacteria and mold, while also preventing freezer burn.
Yes, but the method depends on the type of machine:
Chamber Vacuum Sealers: These are ideal for liquids (like soups or sauces) because the pressure inside and outside the bag remains equalized, preventing the liquid from being “sucked” out.
External Suction Sealers: These can be tricky. It is usually recommended to partially freeze the liquid first or use a “pulse” setting to stop the suction before moisture reaches the sealing bar.
While both remove air, they differ in presentation:
Standard Vacuum Sealing: The bag is evacuated of air and sealed, often resulting in a wrinkled appearance.
VSP (Skin Pack): Uses a thin, highly flexible film that gently drapes over the product like a “second skin.” This is commonly used for high-end meats and seafood because it prevents product deformation and offers a premium retail look.
Yes. Vacuum sealing is not a substitute for refrigeration or freezing. While it removes oxygen, anaerobic bacteria (which thrive in low-oxygen environments) can still grow at room temperature. Always store vacuum-sealed perishables in the fridge or freezer to ensure safety.
If a package “leaks” or loses its vacuum, it is usually due to one of three things:
Punctures: Sharp items like bones or hard plastic granules can create micro-tears.
Poor Seal Integrity: If the sealing bar was too hot (melting the bag) or too cool (not fusing it), the seal may fail.
Moisture/Contamination: If liquid or powder gets into the seal area during the process, it can prevent a perfect airtight bond.
