Sustainable food packaging: a UK buyer's guide

Switching to sustainable food packaging is no longer a nice-to-have for UK hospitality and foodservice. Customers expect it, and regulation is moving fast. This guide walks through the practical choices, so you can move away from problem plastics without compromising on performance or budget.

Why it matters now in the UK

The UK's Plastic Packaging Tax applies to plastic packaging with less than 30% recycled content, and Extended Producer Responsibility (EPR) is shifting the cost of packaging waste onto the businesses that put it on the market. Together they make recyclable and recycled-content packaging the commercially sensible default, not just the ethical one.

For foodservice operators, the brand benefit is just as real: diners increasingly notice and reward visibly recyclable or compostable packaging.

The main sustainable materials

Kraft and corrugated board: widely kerbside-recyclable, strong, and easy to print. Ideal for boxes, sleeves and trays.

Bagasse (sugarcane fibre): a by-product of sugar production that is home- or industrially-compostable, sturdy, and microwave- and freezer-safe. Great for hot and wet food.

Greaseproof and food-grade papers: recyclable wraps, bags and liners for bakery, deli and fried food.

Recyclable plastics (rPET): where a clear, rigid container is essential, choosing recycled-content, widely-recyclable plastic keeps you on the right side of the tax.

Matching material to your food

Hot and saucy food needs grease resistance and rigidity: bagasse trays and clamshells or coated board perform best.

Cold grab-and-go often suits recyclable board with a window, or rPET where clarity sells the product.

Dry and ambient goods are the easiest win: kraft boxes, paper bags and cartons are all recyclable and brandable.

Avoiding greenwashing

Be precise about claims. 'Recyclable' means kerbside-recyclable in the UK; 'compostable' should specify home or industrial. Look for recognised certifications and keep evidence on file.

If you print on packaging, water-based or compostable inks and minimal lamination keep the item recyclable.

How to switch without disruption

Start with your highest-volume lines, where the tax and brand impact are biggest. Order samples, test them with your actual food, and confirm sizes before committing.

A supplier who stocks for short-notice orders and can custom-print to your brand makes the transition far smoother.

Frequently asked questions

What is the most sustainable food packaging in the UK?

For most UK foodservice, widely-recyclable fibre packaging (kraft and corrugated board) and compostable bagasse are the most sustainable mainstream choices. Use recyclable board and paper for dry and ambient food, and compostable bagasse for hot, wet or oily food where recycling is impractical.

Is sustainable packaging more expensive?

Not necessarily. Fibre-based packaging like kraft, corrugated and bagasse is outside the scope of the UK Plastic Packaging Tax, and right-sizing your packaging reduces material cost. Many businesses find the total cost is comparable once the tax and waste savings are included.

How do I avoid greenwashing with packaging claims?

Be specific and keep evidence. 'Recyclable' should mean kerbside-recyclable in the UK, and 'compostable' should state whether it is home or industrial, against a recognised standard. Avoid vague 'biodegradable' claims on their own.
