Specs, explained
- Micron(Micrometre, um, mu)
- A unit of thickness equal to one thousandth of a millimetre, used to measure plastic films such as pallet wrap and mailing bags. Higher micron means a thicker, tougher film. More
- Kraft paper(Brown paper, Kraft wrapping paper)
- A strong, tear-resistant paper made by the kraft pulping process, usually brown. It is widely used for wrapping, void fill, mailers and paper tape. More
- Recyclable packaging(Recyclable materials, Kerbside recyclable packaging)
- Packaging that can be collected, reprocessed and made into new products. Recyclability depends on the material and on whether local facilities actually accept it. More
Poly mailers vs paper mailers
Two mailing-bag routes — one prioritises water resistance and cost, the other recyclability and feel.
Poly mailers
Waterproof, lightweight, lowest cost.
Best for: Weather protection and lowest postage
- Fully waterproof and tear-resistant
- Lightest option — keeps postage down
- Recycled-content versions available
- Recycle at soft-plastic points, not kerbside
Paper mailers
Kerbside recyclable, premium unboxing.
Best for: Plastic-free, brand-led despatch
- Kerbside recyclable
- Premium, natural feel
- Less water resistance than poly
- Slightly higher cost per unit
Common buyer questions
What packaging do I need for ecommerce orders?
A box or mailing bag sized to the product, void fill or bubble wrap so nothing moves, plus tape and a courier label. Right-sizing keeps postage and damage down.
Poly or paper mailing bags — which should I use?
Poly mailers are waterproof, lightest and cheapest; paper mailers are kerbside recyclable with a premium feel but less water resistance.
Can you supply plastic-free packaging?
Yes — paper mailers, kraft void fill, paper gummed tape and compostable food packaging. We keep eco claims specific and accurate.
Which boxes fit Royal Mail Large Letter?
Boxes within 353 × 250 × 25mm post as a Large Letter. Our PiP postal boxes are cut to sit inside those limits so you pay the cheaper rate.
