34cm Wide — Exactly the Limit of a Standard Machine, Exactly the Right Size for a Pizza
The standard LAVA vacuum sealer bar, on the V.300 and V.333 range, is 34cm. This bag is 34cm wide. That means the bag opening spans the entire sealing strip from edge to edge, with no excess film folding over the bar on either side.
Best on a 36cm+ Bar
On a 34cm bar, the bag must be centred carefully every cycle. On a 36cm bar such as the V.350, there is enough side clearance to position the bag more quickly and reliably.
Designed Around Standard Pizza Base Sizes
That is useful because the 34cm width is precisely what a standard 30-33cm pizza base needs. A 30cm pizza fits within the bag with 2cm on either side, enough to position the crust away from the bag walls while the vacuum draws the film tightly around the base. A 33cm pizza sits with less than 1cm on each side, snug, but with no wasted film. For a home cook or a small food business vacuum sealing pizza dough or par-baked pizza bases for freezer storage, the 34 x 50cm produces a close-fitting, properly sized pack without using a bag that is wider than necessary.
Pizza Bases
A 30-33cm pizza base fits the 34cm width closely, giving enough room around the crust without moving into an oversized bag.
Flatbreads and Focaccia
A large wide focaccia or flatbread at 30-32cm width fits cleanly without using a wider industrial-format bag.
Large Flat Fish
A large whole flat fish such as flounder or sole at 30-33cm body width and 40-45cm body length suits this wider, flatter format.
Wide Flat Cuts
A wide brisket flat, large bone-in pork chop, or any wide flat product that fits a 34cm bag width and needs 47cm of usable length.
Why Positioning Matters
When a bag is exactly as wide as the seal bar, there is no margin for off-centre positioning. If the bag drifts 5mm to one side during placement, one edge of the bag will not be fully welded. On a 36cm bar such as the V.350, the bag has 1cm of clearance on each side, enough margin to position quickly in a production run. On a 34cm bar such as the V.300 and V.333, the bag must be positioned centrally every cycle. For occasional home use this is manageable. For repeated production cycles, the V.350 eliminates that precision requirement.
Same R-Vac Construction
The fleece-layer construction and material specs are identical to every R-Vac bag. Swiss-made PA/PE multilayer, 90-micron, plasticizer-free, dishwasher-safe, rated for multi-year freezer storage and up to 95°C. Any vacuum sealer with a 34cm or wider seal bar handles this bag.
Best For
Pizza bases at 30-33cm diameter, focaccia and wide flatbreads, large whole flat fish, wide flat cuts, and any product that is 30-34cm wide and between 38cm and 44cm in length.
Machine Compatibility
Compatible with the V.350 Premium L, which is recommended, and all wider LAVA cryovac machines. Also compatible with V.300 and V.333 with careful centred positioning.
R-Vac 34 x 50cm — Common Questions
Can I use this bag on my V.300 or V.333?
What is the difference between this bag and the 35 x 60cm pizza bag?
What is the difference between this bag and the 30 x 50cm?
Can I use this bag for sous vide?
Yes, up to 95°C for up to 2 hours. The 34cm width suits wide flat proteins, a large chicken breast, a wide fish fillet, that benefit from lying flat in the water bath. For extended cooks above 70°C lasting more than 2 hours, use H-Vac cooking bags rated for long high-temperature cooking.
