About the H-Vac Vacuum Cooking Bags
H-Vac cooking bags
The cooking bag, where standard bags stop
Standard LAVA bags are rated to 95 °C for up to 2 hours, which covers most sous vide. H-Vac is for the cooks beyond that: long, hot sous vide, reheating in boiling water and vacuum cooking in a pressure cooker, from −30 °C in the freezer to 121 °C.

- 70 °C
- Up to 72 hours

Standard bag or cooking bag?

R-Vac, RS-Vac, E-Vac and ES-Vac: the right bag for most sous vide, and cheaper per bag. See the R-Vac bags.
H-Vac cooking bags
Longer, hotter cooks
Over 70 °C for more than 2 hours, boiling-water reheating or the pressure cooker.
Where the H-Vac makes sense:
Short rib
72 °C for 48–72 hours, where standard weld seams can weaken over time.
Brisket
68 °C for 36–48 hours, low and slow.
Pork belly
70 °C for 24–36 hours, with the bag holding throughout.
Duck confit
82 °C for 10–12 hours, a demanding hot cook.
Why it works
Juices held back, seal made first
- 01
Slow draw
The patented fleece layer moves liquid slowly towards the open end.
- 02
Made for long cooks
Proteins release more moisture and fat at high temperatures over many hours.
- 03
Time to seal
The sealer closes the bag before liquid reaches the weld.
Seal, freeze and cook from frozen in the same bag; at service, reheat sealed portions in boiling water, a common restaurant technique. Swiss-made PA/PE multilayer, plasticiser-free, BPA-free and microplastic-free, freezer-safe for years, dishwasher-safe and reusable. It works with every external vacuum sealer, including all LAVA vacuum sealers, and with a sous vide stick.
Sizes
Which size for which cook
| Size | Usable length | For |
|---|---|---|
| 15×30cm | About 27cm | Single fillets, small chicken portions, thin cuts |
| 20×30cm | About 27cm | Chicken breasts, fish fillets, pork chops, meal portions |
| 25×35cm | About 32cm | Duck breasts, thick steaks, wider portions |
| 30×40cm | About 37cm | Short rib, pork belly, brisket flat, bone-in cuts |
Leave room at the top
For long cooks, choose a bag that leaves 3–5cm clear above the product at the open end. If the product presses against the seal area, the weld is at risk during the cook. 50 bags a pack; custom sizes from 5,000 units.
For cooks under 2 hours below 95 °C, a standard R-Vac bag performs just as well and costs less. Use H-Vac when the 95 °C, 2-hour limit isn't enough.

04 · FAQ
Common questions
What is the difference between the H-Vac and the standard R-Vac bag?
Temperature resistance and weld integrity under extended heat. Both are Swiss-made PA/PE multilayer fleece-layer bags with identical food safety, BPA-free, and plasticizer-free specifications. TheR-Vac is rated to 95°C for up to 2 hours — right for the vast majority of sous vide cooks. The H-Vac retains full weld integrity at 85°C for up to 72 hours, at 100°C for up to 2 hours, and at 121°C for up to 30 minutes. If your cook stays under 95°C and under 2 hours, the R-Vac is the right bag. If it goes longer or hotter, use the H-Vac.
Can I use H-Vac bags for boiling?
Yes. The H-Vac is rated to 100°C for up to 2 hours, it handles direct boiling water immersion. This makes it suitable for reheating vacuum-sealed portions in boiling water at the time of service, a common technique in restaurant settings.
What about freezer storage?
Yes. The H-Vac is rated for multi-year freezer storage at -30°C, the same as the standard R-Vac bags. You can seal, freeze, and cook from frozen in the same bag.
Can I use these with my existing vacuum sealer?
Yes. The H-Vac works with all external vacuum sealers on the market, including all LAVAvacuum sealers.
Can I cook long-duration sous vide in a standard R-Vac bag?
Yes. The H-Vac works with all external vacuum sealers on the market, including all LAVA vacuum sealers.
Are custom sizes available?
Yes. Custom H-Vac bags are available from 5,000 units. Contact LAVA Australia to discuss dimensions and pricing.
