The Large Gusseted Bag for Aromatic Dry Goods
The K-Vac is LAVA's metallised gusseted bag, built for dry goods that need protection from light, aroma loss, air, and moisture.
Mid-Range Size
Useful for household quantities, medium refills, and dry goods where a smaller pouch is enough.
Large Household Size
Twice the 500ml size, suited to larger coffee, tea, spice, grain, flour, and sugar storage.
Bulk-Size Format
Better when the 1000ml is not enough and the product needs true bulk storage.
Why Clear Bags Are Not Enough
Coffee, tea, dried herbs, and spices lose aroma and degrade when exposed to light. A clear vacuum bag protects against air and moisture but lets light through.
The K-Vac's metallised foil blocks light completely, so the contents keep their flavour and colour far longer.
Large Stand-Up Gusseted Format
The gusset lets the bag expand at the base and stand upright, holding a useful volume of loose product without tipping.
At 1000ml this is the large size. It suits a full bag of roasted beans, a generous loose-leaf tea or spice quantity, or grains, flour, and sugar in household bulk.
Light Barrier
Metallised foil blocks light to help preserve flavour, colour, and quality.
Aroma Barrier
Made for coffee, tea, herbs, spices, hops, and other aroma-sensitive dry goods.
Airtight Seal
Helps protect large household quantities from air and moisture exposure.
Strong Film
The 124-micron multilayer film is strong, tear-resistant, and suited to larger fills.
Full Bags of Coffee Beans
Suitable for roasted coffee beans and ground coffee where light blocking and aroma retention matter.
Loose-Leaf Tea
Gives generous tea quantities a stand-up pouch format with protection from light, air, and aroma loss.
Dried Herbs and Spices
Ideal for larger household quantities of ground spice, dried herbs, and aromatic seasoning blends.
Hops
Useful for hops and other aromatic ingredients that need airtight, light-blocking storage.
Sugar, Rice and Grains
Works for household bulk quantities of sugar, rice, grains, flour, and similar dry pantry goods.
Large Household Quantities
The right size when the 500ml is too small but the 2000ml is more than needed.
Film Strength and Machine Compatibility
At 124 microns the film is strong and tear-resistant, food safe, free of BPA and plasticizers, and rated for years of cold and freezer storage.
It seals on both chamber and external vacuum machines, so you do not need specialist equipment, though not every machine can weld aluminium composite foil, so check yours first.
Verified buyers confirm both points: one notes the bags are "perfect for my coffee," another that they "work great even with external vacuum sealers."
Best For
Full bags of coffee beans, loose-leaf tea, dried herbs and spices, hops, sugar, rice, grains, and other aromatic or light-sensitive dry goods in large household quantities.
Machine Compatibility
Compatible with both chamber vacuum packers and external vacuum sealers, including the LAVA machine range. Confirm your machine is rated to seal aluminium composite foils before ordering.

These are smooth bags. No idea how, but they work great even with external vacuum sealers.
