About the RS-Vac Bags (Extra-Strong, 160 Microns)
RS-Vac bags
When a standard bag reaches its limit
Heavy duty vacuum seal bags for sharp edges, exposed bone, heavy handling and long freezer storage. The RS-Vac isn't a replacement for the everyday R-Vac; it is the upgrade for when a split bag is not an option.

Why thicker
Built for bones, fins and sharp edges
Puncture resistance
T-bones, ribs, bone-in lamb, whole fish with fins and spines, and hard-rind cheese press against the bag; 160 microns resist them through vacuuming, freezing, stacking and transport.
Long-term storage
Thicker film improves strength, the oxygen barrier and seal durability over time: for venison, bulk meat and seasonal freezer stock.
Liquids under control
The patented fleece layer slows juices and brine, so the seal is made before they reach the weld.
Tear-resistant
A dense structure for processing, handling, stacking and transport.
Before you buy
Can your sealer weld 160 microns?
Every LAVA vacuum sealer seals 160-micron film. Many consumer sealers stop at 90 to 120 microns: on an underpowered machine the bag isn't damaged, but the seal is weak or incomplete, which defeats the point of a heavy-duty bag. With another brand, check its maximum foil thickness first.
Compare
R-Vac or RS-Vac?
| R-Vac 90µm | RS-Vac 160µm | |
|---|---|---|
| Boneless meat, meal prep | Yes | Yes, more than needed |
| Sharp edges and bones | Not recommended | Yes |
| 12+ months in the freezer | Yes | Better |
| Sous vide | Yes | Yes |
| Machines | All external sealers | LAVA; check others |
| Cost | Lower | Higher |
The simple rule: RS-Vac for bone-in and demanding jobs, R-Vac for standard, boneless food. Both share the Swiss PA/PE multilayer film with the fleece layer, the same food safety and temperature ratings. Cutting your own lengths? The ES-Vac rolls are the same 160-micron film on a roll.

Sizes and specifications
The toughest bag in the LAVA range — built for when standard bags aren’t enough. At 160 microns, RS-Vac bags are around 75% thicker than the standard R-Vac (90 micron) , delivering maximum puncture resistance for sharp edges, exposed bone, and demanding long-term freezer storage. Ideal for hunters, fishers, bulk buyers, and anyone sealing high-value food where failure is not an option. Available in five practical sizes (16×25cm to 40×60cm) to suit everything from small portions to large cuts. MIX & VALUE pricing applies automatically from 2 packs — no code needed.

Example: 4 packs of R-Vac bags + 2 packs of E-Vac rolls = 6 packs, so all six get 10% off.Bulk cartons are fixed price and A-Vac dry-aging bags don't count.
04 · FAQ
Common questions
Can my vacuum sealer handle 160-micron bags?
All LAVA machines seal 160-micron foil without issue.
If you’re using another brand, check your machine’s maximum foil thickness specification first. Many consumer-grade sealers are limited to 90–120 microns.
If your machine is underpowered, the result won’t be damage — but a weak or incomplete seal, which defeats the purpose of using a heavy-duty bag.
What is the difference between the RS-Vac and R-Vac bags?
It comes down to thickness and protection.
RS-Vac: 160 microns — built for maximum puncture resistance and long-term storageR-Vac: 90 microns — ideal for everyday use at a lower cost
Both use the same Swiss-made PA/PE multilayer construction with patented fleece layer, and share identical food safety standards, temperature ratings, and machine compatibility.
Simple rule:
Use RS-Vac for bone-in or demanding applications.
Use R-Vac for standard, boneless products.
Are the RS-Vac bags reusable?
Yes — suitable for up to 95°C for up to 2 hours.
The thicker material does not affect sealing or vacuum performance.
For longer cooks above 70°C (over 2 hours), LAVA recommends dedicated H-Vac cooking bags.
Can I mix RS-Vac sizes in one order and still get MIX & VALUE pricing?
Yes. They are dishwasher-safe and reusable.
After cutting open, simply re-seal the remaining length — as long as there is enough material to position the bag correctly on the sealing bar.
Can I mix RS-Vac sizes in one order and still get MIX & VALUE pricing?
Yes. The discount is based on the total number of packs in your cart, not the size.
Mix any RS-Vac sizes and MIX & VALUE pricing applies automatically from 2 packs.
Do you have RS-Vac bags in custom sizes?
Yes — custom sizes are available from 2,000 units.
