// What It Is

The traditional coffee bag, done well

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

High-quality protection at a competitive cost

It’s the price-conscious choice that still delivers on barrier, branding and shelf appeal — which is why it stays a roaster favourite.

01

The most affordable format

A single rear seal keeps construction simple, so it lands at a lower price point than box bottom bags or stand up pouches.

02

Strong K-seal base

The angled K-seal takes stress off the seals and helps the bag stand, making it suitable for heavier products.

03

Printable on all four sides

Front, back and both gussets carry your graphics, story and product information in up to 8 colours.

04

Eco options stay cheaper

Even in recyclable or compostable film it holds a lower price point than the same material in a box bottom bag or pouch.

// Options & Add-Ons

Configure it to your product

Start with a stock bag or spec a custom run — here’s what the side gusset does well, and one honest limitation to know.

One-way degassing valve

A round valve lets CO₂ escape from freshly roasted beans without letting oxygen in, keeping coffee fresh for longer.

Tin tie or roll-down close

Close the top by folding or rolling and securing with a tin tie or tape — simple, tactile and on-brand for artisan coffee.

Rear-corner seal

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.

Spot matt varnish

PET side gusset bags can carry a durable spot matt varnish so your design stands out on the shelf.

Good to know: no zip

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.

Sizes for retail & wholesale

Sized by coffee weight from 250g up to 1kg, plus larger wholesale formats — 250g is the most popular UK retail size.

Side gusset bags, answered

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 and compostable materials.

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.

Yes. They can be made in recyclable mono-material PE, PCR film with a post-consumer recycled core, or home and industrial compostable film, as well as kraft and high-barrier structures — and stay more affordable than the same materials in other formats. See our materials comparison.
