Gusseted and Light-Blocking — Built for Coffee, Tea and Spices
The K-Vac is LAVA's metallised gusseted bag, built for aromatic dry goods that need protection from air, moisture, aroma loss, and light exposure.
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.
Stand-Up Gusseted Format
The gusset is the other half of the design. The bag expands at the base, so it stands upright and holds a useful volume of loose product without tipping.
At 250ml this is the single-portion size, right for a batch of roasted beans, a refill of loose-leaf tea, or a measured quantity of ground spice.
Coffee Beans and Ground Coffee
Suitable for roasted beans, ground coffee, small batches, refills, and single-portion storage where aroma retention matters.
Loose-Leaf Tea
Keeps tea protected from light and air while the stand-up gusset makes the bag easier to fill and store.
Dried Herbs and Spices
Ideal for measured quantities of ground spice, dried herbs, seasoning blends, and aromatic dry ingredients.
Hops and Aromatic Ingredients
Useful for hops and other aroma-sensitive ingredients where light blocking and airtight storage are important.
Sugar, Rice and Dry Goods
The 250ml capacity works well for small dry-good portions, refills, sample batches, and measured quantities.
Cold and Freezer Storage
The film is rated for years of cold and freezer storage, making it useful beyond standard pantry storage.
Machine Compatibility and Sealing
The film is a PET / metallised PET / PE multilayer at 102 microns, 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 use these for exactly this purpose, with reviews noting coffee and hops storage and clean seals on a standard LAVA machine.
Best For
Coffee beans and ground coffee, loose-leaf tea, dried herbs and spices, hops, sugar, rice, and other aromatic or light-sensitive dry goods in single-portion 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.
