47cm Usable — The Right Length for Medium Fish, Tenderloins and Long Asparagus
Within the 20cm-wide R-Vac series the lengths run: 20cm, 30cm, 40cm, 50cm, 60cm, 80cm. The 20x50cm is the middle step, chosen when the 20x40cm's 37cm of usable length is too short but the 20x60cm's 57cm produces noticeable excess film at one end of the product.
The Middle-Length Option in the 20cm Series
This format gives enough room for products around 38-44cm long without forcing buyers into a 60cm bag that leaves unnecessary empty film above the product.
Medium Whole Fish
A whole bream, medium flathead, perch, or school snapper at 38-44cm in body length sits correctly in the 47cm of usable space, with clean clearance at the open end for the weld.
Full Pork Tenderloins
A large pork tenderloin at 40-45cm, sealed intact for roasting or for a long sous vide cook, fits the 20x50cm with room for a clean weld above the narrow tip of the fillet.
Full Asparagus Bundles
Fresh asparagus at market length, typically 40-45cm from tip to base, goes into the 20x50cm without trimming. The 20cm width handles a standard rubber-banded bunch cleanly.
Two Portions End-to-End
Two 20-22cm chicken breasts or two fish fillets placed head-to-toe in the same bag span approximately 40-44cm in length and sit within the 20x50cm's usable space.
Long Leeks at Full Length
A mature leek at full harvest length, 40-48cm from root to dark tip, fits the 20x50cm without being trimmed or folded. The 20cm width handles the full leek diameter without compression.
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 20cm or wider seal bar handles this bag, every machine in the LAVA vacuum packaging range qualifies.
Best For
Medium whole fish at 38-44cm body length, full pork tenderloins at the longer end, full-length asparagus bundles, double portions end-to-end, long leeks and full-length vegetables, and any product that is 20cm wide and between 38cm and 44cm in length.
Machine Compatibility
Compatible with all LAVA vacuum packaging machines and all other external vacuum sealers on the market.
R-Vac 20 x 50cm — Common Questions
What is the difference between the 20 x 50cm, the 20 x 40cm, and the 20 x 60cm?
Length only, all three are 20cm wide with identical Swiss-made PA/PE multilayer construction. The 20 x 40cm provides approximately 37cm of usable internal length, for large chicken breasts, long fish fillets and products up to 35cm. The 20 x 50cm provides approximately 47cm, for medium whole fish, full tenderloins, and asparagus at 38-44cm. The 20 x 60cm provides approximately 57cm, for whole salmon sides, game shanks and full-length cuts up to 55cm. Choose the size that gives your product 3-5cm of clearance above the open end before sealing.
Can I use this for sous vide?
Can I reuse these bags?
Yes. They are dishwasher-safe and reusable. Once cut open, a new seal can be made from the remaining material as long as enough length remains to position across the seal bar.
