Vacuum Packaging
Our Vacuum Bags
Not all vacuum bags are equal — and using the wrong bag for the wrong job produces poor results. Here's everything you need to choose correctly.
The Single Most Important Thing to Know
You must use embossed (textured, ribbed) bags with LAVA external vacuum sealers. The channel pattern allows the vacuum pump to draw air from the entire bag. Smooth bags block the channels — the machine cannot achieve a full vacuum and the seal will fail. Smooth bags are only for chamber vacuum machines.
Embossed vs Smooth — When to Use Each
Embossed Bags (Textured)
Use with LAVA external sealers
- Meat, fish, poultry
- Hard cheese
- Vegetables and fruit
- Dry goods (nuts, coffee, rice)
- Game meat portions
- Most household applications
Smooth Bags
Chamber machines only
- Liquids and sauces
- Commercial food processing
- Smooth presentation requirements
Do not use smooth bags with LAVA external sealers
Size Guide
| Bag Size | Best For | Approx Portion Size |
|---|---|---|
| 15×25 cm | Cheese portions, small steaks, fish fillets | 150–300g |
| 20×30 cm | Standard portions — most common size | 300–600g |
| 25×40 cm | Larger steaks, game cuts, chicken pieces | 600g–1.5kg |
| 30×60 cm | Whole fish, full roasts, bulk portions | 1.5–5kg |
| Custom (rolls) | Any size — cut to the exact length needed | Any |
LAVA Bag Quality — What Makes Them Different
BPA-Free
All LAVA bags are 100% BPA-free. Safe for food contact, freezer storage and boiling (sous vide).
5-Layer Construction
PA/PE multi-layer structure — the outer nylon layer protects against puncture, the inner polyethylene layer is food-safe and creates the seal.
Freezer-Safe
Rated for temperatures down to -40°C. Will not become brittle or crack in the freezer, even after years.
Microwave & Boilable
Safe for sous vide (up to 90°C). Can be used in the microwave with the seal opened for ventilation.
Reusable for Dry Goods
Bags used for dry goods (nuts, coffee, rice) can be washed and reused. Do not reuse bags that contained raw meat, fish or cooked food.
Precision-Cut Edges
Straight-cut edges that seal cleanly and evenly with the LAVA sealing strip — no uneven sealing from inconsistent bag edges.
Vacuum Rolls — When to Use Them
LAVA vacuum rolls let you cut bags to any custom length. This is especially useful for:
- Irregularly shaped items — a whole fish, a boneless leg of lamb, an odd-shaped game cut
- Very long items — a full pork belly, a side of salmon
- Minimising waste — cut exactly the length you need instead of using a pre-sized bag that's too large
Rolls are also more economical per square centimetre of bag material — useful if you seal large quantities regularly.
