Kitbest Biodegradable Bin Bags Liner 120pcs (20L) – Compostable Food Waste Caddy Liners, 50 x 60cm

If you’re trying to make small, daily changes to your kitchen waste routine, compostable bin liners can be a surprisingly practical step. The Kitbest Biodegradable Bin Bags Liner set is aimed at food waste caddies and smaller indoor bins, with a 20-litre capacity and liners sized 50 x 60cm. On paper, it’s a straightforward “line your bin, then deal with the waste” approach—nothing fancy, but that simplicity is often what you want.

That said, it’s worth being a bit realistic: compostable/biodegradable bags don’t turn all waste into compost by magic. Their usefulness depends on where and how you dispose of them. If you’re already set up for proper composting, these liners should slot into your routine with minimal fuss.

Key takeaways

These are small-bin liners for everyday indoor use, particularly food waste. The material is described as compostable and biodegradable and made from corn starch, with the brand also positioning them as non-toxic and suitable for regular waste handling. They come as 120 bags (6 rolls, 20 bags per roll), so you’re not constantly running out.

The bag format is designed to be easy to tear off thanks to a break point design. There’s also an emphasis on thicker, more robust liners intended to help reduce punctures, leaks, and tears—handy when you’re dealing with damp food scraps.

Where they fit best is the “mid-level” practical buyer who wants compostable liners without going too niche or overcomplicated. If you need something for general household rubbish that you’ll treat as standard refuse, you may still prefer conventional bin bags for convenience.

What to know before you buy

Start with the basics: these are 20-litre liners and the size is 50 x 60cm. That means they’re most likely to suit typical kitchen caddy and smaller pedal bins, rather than large outdoor bins.

The product description also mentions an octagonal design at the base, intended to help with corners and a fuller load. In real life, that sort of bottom shaping can make the liner sit better in bins with more structured sides. It won’t remove the need to check fit, but it may reduce the “bag bunching” you sometimes get with flatter liners.

You’ll also want to think about your composting setup. If you can only dispose of waste through regular landfill routes, you might not get the benefit you’re aiming for, even if the bags are compostable by design.

The essentials for everyday use

For a typical micro-routine: line your food waste caddy, add your scraps during the day, then lift and tie off when you’re ready to empty it. Because the liners are intended for food waste use and are described as thicker, they’re meant to handle the normal messiness of kitchen scraps better than very thin bags.

There’s a lot of focus on tear-off convenience and durability. The break point design is there so you can pull off a single liner without it tearing unpredictably. The description also suggests the liners are less prone to punctures and leaks, which is the sort of thing you notice quickly if you’ve ever had damp rubbish seep through a cheap liner.

No product is perfect, though: if your bin has an unusual shape or you overfill it, any liner can struggle. In other words, it’s best when you use the right capacity and don’t try to cram in more than you should.

Where it shines (and where it may not)

These liners are a good match if you’re specifically lining kitchen/indoor bins for food waste and you care about compostable, biodegradable materials. They’re described as suitable for indoor spaces like the kitchen, bathroom, living room, bedroom, and office, and the list of suggested uses includes things like nappies, pet waste cleanup, cat litter, and recycling waste.

It might not be for you if you mainly need large, heavy-duty bags for general outdoor refuse, or if your disposal route doesn’t support composting. You may also want to skip if your bin is larger or the shape doesn’t suit 50 x 60cm liners—because while the brand mentions a fit for many pedal bins, “most” still leaves room for exceptions.

Worth considering if you already buy compostable liners and you want a multi-pack that reduces restocking frequency.

In the box / pack overview

You get 120 biodegradable bin bags in total, supplied as 6 rolls with 20 bags per roll. That roll format can be handy for keeping everything together under the sink or near your caddy.
