02. Sizes and Gussets

Custom Sizes and Gusset Widths

Quoted as width × height × gusset width (for example 100 × 300 + 80 mm). Common fills: 100 g, 250 g, 500 g, 1 kg and 5 kg.

One-way degassing valve fitted to a coffee bag
03. Degassing Valves

One-Way Degassing Valve

Fitted on the front panel so roasted coffee can release CO2 without oxygen entering — protects aroma and shelf life.

Multilayer barrier film structure
04. Material and Barrier

Aroma-Barrier Material Structures

PET/AL/PE, PET/VMPET/PE and kraft/AL/PE laminates with aluminium foil or metallised layers for oxygen and moisture protection.

Gravure printed flexible packaging finishes
05. Printing and Finishes

Custom Printing and Surface Finishes

Gravure printing with Pantone matching — matte, glossy, soft-touch, spot UV or a natural kraft look.

Resealable zipper and tin-tie closures on kraft bags
06. Closures and Features

Closures and Opening Features

Resealable zipper, tin-tie, round hang hole, tear notch and clear window — combined to suit how your customers open and store the bag.

How side gusset sizes are quoted

Side gusset bags are specified as Width × Height × Gusset width — the gusset is the inward fold on the left and right edges. A 500 g coffee bag is typically around 100 × 300 + 80 mm.

Side gusset means the folds sit on both sides of the bag. A bottom gusset is a different construction — tell us which one your filling line needs and we will quote the matching structure.

Every side gusset bag is built to your gusset width, barrier level, printing and closures.
