About the Z-Vac Vacuum Zipper Bags 20×30cm (50 Bags)

How it works
From vacuum bag to everyday storage
- 01
Fill the bag
Load the food as you would any vacuum bag.
- 02
Vacuum seal
Open end into the sealer, a normal vacuum and seal cycle.
- 03
Open above the zipper
When you first need the contents.
- 04
Zip it closed
Open and close it again between uses.

The weld holds the vacuum, the zipper the contents
Until you first open it, the bag is fully vacuum sealed by the heat seal. After that, the zipper is a secure closure for continued storage, not a vacuum: fast access, portion control and less waste.
Same vacuum
Still a real vacuum bag

The embossed fleece layer on one side draws the air out fast and evenly, and the weld makes a strong, airtight barrier. It is the Swiss-made PA/PE multilayer film of the R-Vac bags, with a zipper added.
Ordinary zip bags

Best for
Food you come back to
Snacks and dry goods
Nuts, coffee, dried fruit and jerky.
Cheese
Portions you use over a week or two.
Leftovers
Fridge food you go back to over several days.
Pantry staples
Herbs, spices and anything you open often.

When a standard bag is better
For meat, fish or bulk packs you won't reopen, a standard R-Vac bag is the more economical choice. For cooks over 70 °C longer than 2 hours, use H-Vac cooking bags.
Sizes
One size, or made to order
Z-Vac comes in 20×30cm as a standard product. Custom sizes are made from 50,000 units: contact LAVA Australia for sizes and pricing.

04 · FAQ
Common questions
Does the zipper hold the vacuum, or is it just for closing the bag?
The vacuum is created and held by the heat seal — not the zipper.
The zipper is for convenient access: open, take what you need, and close it again without cutting the bag.
Before first opening, the bag is fully vacuum sealed. After opening, the zipper keeps contents securely stored between uses.
Can I use Z-Vac bags for sous vide cooking?
Yes — suitable for up to 95°C for up to 2 hours.
The zipper does not affect vacuum performance or cooking results.
For longer cooks above 70°C (over 2 hours), LAVA recommends dedicated H-Vac cooking bags.
Do these work with non-LAVA vacuum sealers?
Yes. Z-Vac bags are compatible with all external vacuum sealers.
The embossed fleece structure ensures consistent air extraction across all brands.
Is this the only size available?
Yes — currently available in 20×30cm as a standard product.
Custom sizes can be produced from 50,000 units.
Contact LAVA Australia for details on volume orders, sizing, and pricing.
What is the difference between Z-Vac and standard zip bags?
Standard zip bags are not designed for vacuum sealing:
No channel structure for air extractionThinner materialNot suitable for long-term freezer storage or cooking
LAVA Z-Vac combines a true vacuum-compatible embossed structure with a zipper closure.
That means you get a genuine pump-created vacuum, not just a pressed airtight seal — plus the convenience of easy reuse.
