A split bin bag in a busy kitchen is a hygiene incident, a slip hazard and twenty minutes of a chef's time. Choosing bags by price alone is how that happens. This guide explains the three things that matter (duty, size and format), how colour fits into waste separation, and what the workplace recycling rules in England now require.
1. Duty: how strong does the bag need to be?
Bin bag strength is described as light, medium or heavy duty (and sometimes by gauge, the film thickness). Kitchen waste is wet, heavy and often sharp (tins, bones, skewers), so heavy duty is the safe default for any food business. Light duty bags belong in office paper bins and washrooms, not under a prep bench. Betapro's black bin bags are heavy-duty, tear-resistant film for exactly this reason.
2. Size: match the bag to the bin
Standard UK kitchen and office bins take a bag in the 70–100 litre range; wheelie bins need 240L liners; small pedal bins take 20–30L. A bag that is too small pulls off the rim when it fills; one that is too big wastes film and is harder to tie. Measure the bin's rim circumference and height, and choose a bag whose flat width is just over half the circumference.
3. Format: rolls or loose bags?
- Bags on a roll tear off cleanly one at a time, fit in a dispenser or cupboard, and are easy to count. Best for sites with many bins and a roll by each one. Betapro offers 20-bag rolls and 50-bag rolls.
- Loose or flat-packed bags in a box suit a single central bin store and very large bags.
For a kitchen with four or five bins, 50-bag rolls (fewer changes) beat 20-bag rolls; for offices and hotel housekeeping trolleys, 20-bag rolls are easier to carry.
Colours and waste streams
Colour-coding bags makes waste separation visible: black for general waste, clear for dry mixed recycling, and a distinct colour (often green or brown) for food waste. Even if your waste contractor accepts black bags for everything, staff separate correctly far more reliably when each stream has its own colour and labelled bin.
Simpler Recycling: what changed for businesses in England
From 31 March 2025, workplaces in England with 10 or more employees must separate dry recyclables (paper, card, plastic, metal, glass) and food waste from general waste for collection. Smaller businesses follow from 2027. For a kitchen that means at least three streams in the kitchen and the bin store, three bag types, and a waste contractor who collects them separately. Clear bags for recycling make contamination obvious at the bin store; black bags should now only hold true residual waste.
How many bags will you use?
A takeaway kitchen filling two 90L bins a day uses roughly 60 bags a week, plus recycling and food-waste liners. A 500-bag case lasts about two months for general waste alone. Multi-site operators and cleaning contractors buy by the pallet; ask for a quote and we will size it to your bin count.

Frequently asked questions
What size bin bag fits a standard kitchen bin? Most 70–90L commercial bins take a standard refuse sack; measure the rim to be sure.
Are black bin bags recyclable? The bags themselves are LDPE and can be recycled where soft plastics are collected; what matters more is that only residual waste goes in them.
Do I need food waste bins if I am a small takeaway? In England, businesses with 10 or more employees must separate food waste now; smaller sites follow from 2027. Check your local authority or waste contractor for the current requirement.
