The Mid-Size Gusseted Bag for Aromatic Dry Goods
The K-Vac is LAVA's metallised gusseted bag, built for a problem clear food bags cannot solve.
Smaller Portion Size
Better for single portions, small refills, sample quantities, and smaller batches of aromatic dry goods.
Mid-Range K-Vac Size
Twice the capacity of the 250ml, making it a practical middle size for household and small-batch storage.
Larger Storage Size
Useful when the 500ml is not enough and the product needs a larger pouch for bulk storage.
Why Metallised Foil Matters
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.
Mid-Size Stand-Up Gusset
The gusset lets the bag expand at the base and stand upright, holding a useful volume of loose product without tipping.
At 500ml this is the mid-range size, right for a larger batch of roasted beans, a bigger loose-leaf tea refill, or a household quantity of ground spice, rice, or sugar.
Thicker Film
The 500ml film is a step thicker than the 250ml, giving it stronger handling resistance.
Blocks Light
Metallised foil stops light exposure, helping protect colour, aroma, and flavour.
Preserves Fragrance
Built for products where aroma retention matters, including coffee, tea, hops, herbs, and spices.
Freezer Safe
Rated for years of cold and freezer storage when the product needs longer-term protection.
Larger Coffee Batches
Suitable for roasted beans, ground coffee, refills, and mid-size coffee portions where 250ml is too small.
Loose-Leaf Tea
Works well for bigger loose-leaf tea refills while blocking light and helping preserve aroma.
Dried Herbs and Spices
Ideal for household quantities of ground spice, dried herbs, seasoning blends, and aromatic dry ingredients.
Hops
Useful for aroma-sensitive hops where light blocking, airtight sealing, and cold storage compatibility are important.
Sugar and Rice
The 500ml size works for household quantities of sugar, rice, dry goods, and measured refill portions.
Mid-Range Dry Goods
A practical size when 250ml is too small but the 1000ml K-Vac is more than needed.
Film Strength and Machine Compatibility
At 124 microns the 500ml film is a step thicker than the 250ml, 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.
Best For
Larger coffee batches, loose-leaf tea, dried herbs and spices, hops, sugar, rice, and other aromatic or light-sensitive dry goods in mid-range 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.
