How to Choose Bubble Size: 10mm, 15mm or 25mm

Bubble “size” on our line is the bubble diameter: 10mm, 15mm, or 25mm. It is not the same as film thickness. Buyers who specify only “bubble wrap” often receive a default 15mm roll that is wrong for glass or for PCBs.

10mm — surface protection

Smaller bubbles sit closer together and mark polished or painted surfaces less. Use them for electronics housings, small spare parts, and items where scuffing is the complaint. Pair with antistatic film when ESD is in the spec.

15mm — the packing-cell default

Most e-commerce and general industrial wraps run 15mm. It is a compromise: enough air for mixed cartons without the bulk of 25mm. If you are standardising one SKU for a fulfilment centre, start here and exception the fragile lines.

25mm — drop energy and export

Larger bubbles absorb more impact before the film bottoms out. Glass, ceramics, and long sea-freight cartons usually need 25mm or a foam-plus-bubble stack. Do not use 25mm as a substitute for a proper foam cradle on very heavy items.

• •Also specify width (300–1200mm typical) and roll length.
• •Perforation helps retail wrapping; jumbo rolls suit converting pouches.
• •Antistatic is a grade, not a bubble size.

Send a damaged carton, not just a width

If goods arrive cracked, tell us whether the hit was a corner, a face, or crushing in a container. That decides size versus foam versus a converted pouch. Quotes from Peenya state the bubble size in millimetres, not marketing names.
