R-Vac: Strong bags. Real performance. No weak points.
LAVA vacuum seal bags are built for reliable sealing, longer shelf life, and consistent results — whether at home or in demanding environments.
Most vacuum seal bags are stamped after production — weakening the material exactly where it needs to be strongest.
LAVA bags are different.
Made in Switzerland using a patented multilayer system, the structure is integrated into the film itself — not stamped in.
🔴 No thinning. No weak spots. Just true, consistent 90-micron strength across the entire bag.
Exclusively available in Australia through LAVA.
Compatible with all chamber and external vacuum sealers, these bags are designed for secure sealing and long-term storage — from portion control to bulk packaging.
Looking for more flexibility? Pair them with our vacuum seal rolls for custom sizing, or explore the full range of bag types to find the right solution for your application.
Why LAVA Bags Perform Better
| Feature | Standard Stamped Bags | LAVA R-Vac Multi-Layer Bags |
|---|---|---|
| Structure | Pressed into the foil | Integrated into the film |
| Material Strength | Weakened at contact points | Consistent across the entire bag |
| Thickness | Uneven — thinner where stamped | True, uniform 90 microns |
| Durability | Higher risk of failure | Reliable, long-term use |
| Performance | Inconsistent sealing | Strong, dependable results |
🔴 The difference is simple:
Stamped channelled bags look thick — but they’re weakest where it matters most.
LAVA R-Vac bags deliver true strength across the entire material — no weak spots, no compromises.

Why the R-Vac Is the Standard Choice
The R‑Vac is the best-selling bag in the LAVA range and the go-to choice for everyday use, whether sealing meat, fish, vegetables, meal prep, or sous vide.
At the core is LAVA’s patented fleece layer. Unlike standard embossed bags that can collapse under pressure, the fleece structure stays open. Air is removed evenly and efficiently, giving you a strong, consistent vacuum every time.
It also handles moisture better. Meat juices and marinades move slowly through the fine channels, giving the machine time to seal before liquid reaches the weld.
Durable & high quality PA/PE multilayer film
No plasticizers, tasteless and odourless
Made for long-term freezer storage
