Paper or Plastic? Carrier Bags for UK Food Businesses

For most UK food businesses the practical answer is paper. A charge applies to single-use plastic carrier bags, paper bags carry food loads perfectly well when they're specced correctly, and customers now read a kraft paper bag as the normal, expected way a takeaway arrives. Two decisions actually matter here: handle type and weight rating. An under-specced bag that fails on the walk home undoes everything the kitchen got right.

Here's the landscape, then the practical spec.

The bag charge, in one paragraph

The UK nations require most retailers — food businesses included — to charge for single-use plastic carrier bags. The scheme details, amounts and record-keeping duties differ between England, Scotland, Wales and Northern Ireland, and they change from time to time. So don't take the specifics from a blog post: check gov.uk (or the relevant devolved government site) for the current rules where you trade. The strategic point is stable, though. The charge exists to push single-use plastic out of circulation, and the direction of travel across all four nations runs one way. Build your bag line around paper now and you never revisit this. The same logic applies across your whole packaging line, as covered in our plain-English overview of the single-use plastics rules.

Paper, plastic and compostable: the real options

Kraft paper bags are the mainstream choice. Brown kraft is strong for its weight, prints beautifully if you ever brand it, is widely recycled from home collections, and — not a small thing — sits outside the plastic bag charge regime. The weaknesses are rain resistance, which is limited, and the handles: a badly specced paper bag fails there rather than at the body.

Plastic bags still have a defensible niche in "bag for life" thickness — reusable, charge-compliant in a different category, and rain-proof. For a takeaway handing out hundreds of bags a week, though, the per-bag cost and the optics both argue against plastic as the default.

Compostable bags (typically starch-based) look and feel like thin plastic but are certified to break down in composting conditions. They suit businesses whose whole packaging story is compostable — bagasse plates, fibre cups, the lot. Two honest caveats. Certification is usually for industrial composting rather than a home heap. And their strength under heavy, hot, damp loads sits below kraft paper of equivalent cost.

Handle types, and when each earns its place

Diagram coming soonFour carrier bag handle types side by side — flat folded-paper handle, twisted handle, no-handle counter bag, and SOS block-bottom — each labelled with its strength and the order type it suits.

Two of these deserve a note. The SOS (self-opening satchel) block-bottom bag stands open and square on the counter, and packers love it because boxes drop straight in level — half the battle for leak prevention. The no-handle counter bag is the most under-used money-saver in cafés. A croissant doesn't need a handled bag, and the price difference across a year of pastries adds up.

Weight ratings: spec for your heaviest normal order

Bag strength comes from paper weight (gsm), construction and handle attachment. Rather than memorising gsm charts, spec against your actual orders:

• Light (sandwich, pastry, one drink) — standard kraft with flat handles is ample.
• Medium (two boxed mains, sides, a drink) — this is where cheap bags fail. Look for heavier kraft and twisted or well-bonded flat handles.
• Heavy (family order: four mains, rice, sides, drinks, sauces) — twisted-handle bags in heavy kraft, or double-bag as standing policy. A family order can easily reach several kilograms, and you should assume the customer will carry it by the handles for ten minutes.

Then test it honestly. Pack your heaviest common order, pick the bag up by the handles and carry it around the block. Add a wet element too — condensation from a cold drink against the bag wall — because damp is what actually kills paper handles. If it survives that, it survives your customers.

Heat and steam matter as well. Hot boxes soften a paper bag from the inside. Venting the food properly (see how to keep takeaway food hot without going soggy) protects the bag as well as the food.

Sizing and the packing test

A bag should fit the order snugly. Oversized bags let boxes slide and tip — the number one cause of "it leaked" complaints that were really "it travelled on its side" complaints. Most operators land on two sizes: a medium for one-to-two-item orders and a large for family orders, with the counter bag as a third, cheap line for hand-held items. Match your bag footprint to your box footprint. If you standardised on numbered kraft boxes, check the bag base fits your No.2 flat.

What this costs, and what it signals

Bags are one of the cheapest lines in your packaging spend and one of the most visible. Your bag is what walks down the high street with your logo-shaped reputation inside it, and it's the last thing the customer touches before eating. A sturdy kraft bag with clean handles reads as care. A stretched, failing bag reads as corner-cutting — the same signalling logic that applies to napkins, covered in our napkins and serviettes buying guide.
