Reusable Embossed Vacuum Zipper Bags
The Zipper — What It Actually Changes
This is where Z-Vac stands apart.
Vacuum seal once for full airtight storage. When you’re ready to use the contents, open the zipper, take what you need, and press it closed again — no cutting, no wasted bags.
Before first opening, the bag is 100% vacuum sealed. After opening, the double zipper gives you fast, secure access for everyday use, portion control, and less waste — without committing to single-use bags.
From Single-Use to Everyday Use
Seal it once. Access it whenever you need.
Z-Vac transforms a standard vacuum bag into a practical, reusable storage solution. Vacuum-seal for maximum protection, then open via the zipper as needed.
Perfect for foods you come back to again and again: portioned meat, cheese, snacks, or prepped ingredients.
Double Zipper Convenience
Open. Take what you need. Close again.
The integrated double zipper lets you access the contents without destroying the bag.
Before first opening, the bag is fully vacuum sealed and airtight. After opening, the zipper provides a secure, convenient closure for continued storage.
No scissors. No hassle. No unnecessary waste.
Same Vacuum Performance
This is still a real vacuum seal bag — not a compromise.
The embossed fleece structure ensures fast, consistent air extraction, while the welded seal creates a strong, airtight barrier for long-term storage.
You get the full benefit of vacuum sealing — with added flexibility.
Swiss-Made Multilayer Quality
Built to perform — not just to look good.
Z-Vac bags are made in Switzerland using premium PA/PE multilayer film, combining durability, food safety, and reliable sealing performance.
The same proven material and structure as the R-Vac range — enhanced with zipper convenience.
How It Works
Best Suited For
- Snacks & dry goods — nuts, coffee, dried fruit, jerky
- Cheese portions used over time
- Fridge leftovers accessed across multiple days
- Herbs, spices & pantry staples
- Any food you want to keep protected between uses
When to Choose a Standard Bag Instead
For long-term storage — especially meat, fish, or bulk packs you won’t reopen — a standard bag like R-Vac is the more economical, no-compromise choice.
Machine Compatibility
Compatible with all LAVA vacuum sealer machines and all other external vacuum sealers. Use your machine’s
standard vacuum and sealing cycle — just like a regular bag.
Z-Vac Vacuum Zipper Bags — 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 extraction
- Thinner material
- Not 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.
