Short answer: most bubble mailers aren't easily recyclable in the UK — because they're made of two materials bonded together that the recycling system can't separate. Here's what that means in practice, and the simpler alternative.
Why bubble mailers are a recycling problem
A bubble-lined mailer feels like one thing, but it's two: an outer layer — paper or plastic — bonded to an inner layer of plastic bubble cushioning. That combination is what makes it protective, and it's also what makes it difficult to recycle.
UK kerbside recycling is built around single materials: paper goes with paper, plastic film goes with plastic film (where it's collected at all). A bubble mailer doesn't fit either stream cleanly. If it has a paper outer, the bonded plastic bubble layer contaminates the paper stream. If it's all plastic, it's a flexible plastic — a material that most UK household kerbside collections still don't take.
The result is that the vast majority of bubble mailers either can't go in your kerbside bin, or shouldn't, because they cause problems further down the line.
What the UK's recyclability rules say
Since 2025, the UK has assessed packaging recyclability through a system called the Recyclability Assessment Methodology, or RAM, which underpins how Extended Producer Responsibility (EPR) fees are calculated.
One of RAM's key principles is how it treats packaging made of more than one material. If the components can be separated by hand, they're assessed separately. If they can only be separated by machinery or tools — or not at all — they're assessed together, as a single composite item.
This matters for bubble mailers because most of them bond the layers permanently. You can't peel the bubble lining cleanly out of a standard bubble mailer, so under RAM it's assessed as a composite — and a paper-and-plastic composite is treated as one of the harder-to-recycle, higher-cost categories, not as recyclable paper.
"But can't you just separate the layers?"
A small number of newer "recycle-ready" designs are deliberately engineered so the outer and the bubble lining can be pulled apart by hand, allowing each part to be recycled in its own stream. These do exist — but they're the exception, not the norm, and they come with a catch: they only work if the person receiving the parcel actually separates the two layers and puts each in the correct bin. In practice, many don't, and the mailer ends up in general waste or contaminating a recycling stream anyway.
For the overwhelming majority of bubble mailers on the market, there's nothing to separate — the layers are bonded, and the whole thing is a composite.
The simpler answer: a single-material mailer
The recycling problem with bubble mailers comes entirely from combining two materials. Remove the plastic bubble layer, and the problem disappears.
A mono-material paper mailing bag is made from one material: paper. There's no plastic lining to separate, no composite to assess, and nothing for your customer to pull apart. It goes in the same kerbside paper recycling as cardboard — one of the most widely collected materials in the UK, accepted by virtually every local authority.
Modern paper mailers use cushioned paper padding to protect semi-fragile items, so for many products they do the same job as a bubble mailer without the two-material penalty. For businesses, there's a cost angle too: because paper sits in a lower EPR fee category than plastic or composite, switching your mailers can reduce what you pay — which is why a lot of UK senders are making the move ahead of the 2026 fee changes.
So, are bubble mailers recyclable?
Most bubble mailers sold in the UK are not easily recyclable, because they bond two materials the recycling system can't separate. A few engineered exceptions exist but depend on the recipient separating them correctly. If recyclability matters to you — or you want to lower your EPR fees — a mono-material paper mailing bag avoids the problem altogether.
Frequently asked questions
Usually not. A bubble mailer with a paper outer has a bonded plastic bubble layer that contaminates the paper recycling stream, and an all-plastic bubble mailer is a flexible plastic that most UK kerbside collections don't accept. Check your local council, but for most households a standard bubble mailer belongs in general waste rather than the kerbside bin.
It depends on the construction. If the paper outer and the plastic bubble layer are bonded and can't be separated by hand, the mailer is still a composite and isn't cleanly recyclable. A fully paper mailer — paper outer with paper cushioning and no plastic layer — is recyclable in the normal kerbside paper stream.
For most bonded bubble mailers there's no easy way at home, because you can't separate the layers. Some retailers and supermarket front-of-store collection points take flexible plastics, which may accept all-plastic mailers, but availability varies. The simpler route is to switch to a single-material mailer that recycles with your normal paper and card.
A mono-material paper mailing bag. Because it's one material with no plastic lining, there's nothing to separate, and it goes in the widely collected kerbside paper stream — which also places it in a lower EPR fee category than plastic or composite mailers.
Explore the full EPR packaging range
Every product below is chosen to help lower your EPR fees — by switching to a lower-fee material category, cutting weight, or keeping packaging a single recyclable stream. Start with the EPR-friendly packaging hub for how the fees work, or go straight to a product family:
- Mono-material mailing bags — paper mailers that replace two-material bubble-lined bags, assessed as a single paper component.
- Paper protective packaging & void fill — paper void fill, bubble wrap and honeycomb that replace plastic, recycled in one paper stream.
- Recyclable cardboard boxes — the lowest-fee mainstream material, with SMART fluting to cut weight without losing strength.
- Paper tape & closures — gummed paper tape that seals boxes and recycles with them as one fibre stream.
- Lightweight stretch film — thinner, stronger film that puts less plastic by weight on every pallet.
