Custom Side Gusset Bag Options
Choose the gusset width, size, barrier material, printing and closure to build the right side gusset bag for your product.
Side Gusset, Stand-Up and Flat-Bottom
Side gusset is our core format — the other shapes stay available so one artwork can cover your whole range.
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 on the front panel so roasted coffee can release CO2 without oxygen entering — protects aroma and shelf life.
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.
Custom Printing and Surface Finishes
Gravure printing with Pantone matching — matte, glossy, soft-touch, spot UV or a natural kraft look.
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.
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.
