// Bag Format · Side Gusset Bags
The classic coffee silhouette. A traditional K-seal gusseted bag with excellent barrier protection at the most competitive price point — still the go-to for tea and coffee roasters. Buy stock from our Melbourne warehouse from a single carton, or print your own from 2,000 units.
// What It Is
Side gusset bags are the most traditional packaging choice for tea and coffee. Gussets on each side work as extra panels that expand to hold more product, adding volume and strength, while a sturdy K-seal base takes the strain off the seals.
The K-seal’s 30-degree angle helps the bag carry heavier goods and stand well, so it protects the product while keeping cost down. The rear seal can be centred, or set at the rear corner to leave the back panel clear for labels and graphics with no seam down the middle.
// Why Roasters Pick It
It’s the price-conscious choice that still delivers on barrier, branding and shelf appeal — which is why it stays a roaster favourite.
01
A single rear seal keeps construction simple, so it lands at a lower price point than box bottom bags or stand up pouches.
02
The angled K-seal takes stress off the seals and helps the bag stand, making it suitable for heavier products.
03
Front, back and both gussets carry your graphics, story and product information in up to 8 colours.
04
Even in recyclable film it holds a lower price point than the same material in a box bottom bag or pouch.
// Options & Add-Ons
Start with a stock bag or spec a custom run — here’s what the side gusset does well, and one honest limitation to know.
A round valve lets CO₂ escape from freshly roasted beans without letting oxygen in, keeping coffee fresh for longer.
Close the top by folding or rolling and securing with a tin tie or tape — simple, tactile and on-brand for artisan coffee.
Move the seal band to the rear corner to keep the whole back panel clear for labels and graphics, with no seam running down the middle.
PET side gusset bags can carry a durable spot matt varnish so your design stands out on the shelf.
The single rear seal means side gusset bags can’t take a resealable zip. If you need one, a quad seal bag is the close alternative.
Sized by coffee weight from 250g up to 1kg, plus larger wholesale formats — 250g is the most popular UK retail size.

// FAQ
A side gusset bag is the traditional coffee and tea bag shape, with a gusset folded into each side that expands to hold more product. A sturdy K-seal base takes stress off the seals, helps it stand and lets it carry heavier goods. It’s printable on all four sides.
Its construction is simpler — a single rear seal rather than the multiple sealed corners of a quad seal or box bottom bag — so it comes in at a lower price point, including in recyclable monomaterial.
No. The single rear seal means a side gusset bag can’t take a resealable zip — it’s closed by rolling or folding the top and securing it with a tin tie or tape. If you need a zip, a quad seal bag is the closest alternative.
Yes. A round one-way degassing valve can be fitted so CO₂ escapes from freshly roasted beans without letting oxygen in, keeping the coffee fresh for longer.
