The Same Width — 10cm More Length for Longer Products
The 20 x 30cm is the most popular bag in the range for a simple reason: it fits the widest range of everyday products. A standard chicken breast, a fish fillet, a meal portion, most cuts of meat, the 30cm length covers them all with a comfortable seal area above the product.
Built for Products That Need Extra Length
There is a specific group of products, though, where the 30cm bag is just short enough to be inconvenient. A large free-range chicken breast at its longest can reach 28-30cm, that is against the limit of the 20x30cm's usable length after both welds. A large barramundi fillet, a long trout fillet, or a wide flathead fillet can easily reach 35-37cm. Full-length asparagus bundles from the garden or a farmers market. Two smaller portions are sealed end-to-end to save on bag count. A thick marinated pork tenderloin at full length.
For all of these, the 20 x 40cm solves the problem with 10cm of extra length and no change to width. The bag is 20cm wide, the same as the top-seller, so it fits the same machines, the same roll width, and the same product footprint. The only difference is the room it provides for longer products.
The usable internal length after both end welds is approximately 37cm. Products up to 35cm in length fit with a comfortable seal clearance above the product opening.
Same R-Vac Construction
The fleece-layer construction, material specs, and temperature ratings are identical to every R-Vac bag. Swiss-made PA/PE multilayer, 70-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
Large chicken breasts at full length, long fish fillets such as barramundi, trout, and large flathead, full-length asparagus bundles, two smaller portions sealed end-to-end, long pork tenderloins, whole corn cobs at full husk length, and any product between 30cm and 35cm that sits awkwardly in a standard 30cm bag.
Machine Compatibility
Compatible with all LAVA vacuum packaging machines and all other external vacuum sealers on the market.
