Royal Mail 5cm bubble wrap rule for sending parcels
Royal Mail 5cm bubble wrap rule for parcels

Royal Mail has issued guidance for anyone sending parcels, recommending that fragile items be wrapped in bubble wrap at least 5cm thick.

On its website, Royal Mail advises that when packing fragile items such as glass, china, or resin, you should use bubble wrap at least 5cm thick to protect the item. Start by wrapping any extremities, like the limbs of figurines, then carefully wrap the rest of the item.

Packing and labeling your parcel

Customers should also place their items in a strong, rigid container that is ideally the correct size. If the box is slightly too large, you will need to add more bubble wrap or packing foam to prevent the item from moving around inside.

Once packed, seal the container securely and label the parcel with the full name, address, and postcode, including a return address. Attach the correct postage for the service you need.

Royal Mail notes that fragile items shouldn't touch each other or the sides of the container, so fill any empty space with cushioning material such as bubble wrap or polystyrene chips, available from most Post Office branches. If needed, add a “FRAGILE” sticker.

General advice for other parcels

In general advice for wrapping and packaging mail, Royal Mail urges people to use padded envelopes for sharp edges or odd shapes and to ensure any outer containers are strong enough for their contents.

Write a return address on the item and include a contact name, address, and telephone number inside the parcel. Seal the package securely with nylon or vinyl tape along all edges and openings, flattening any sharp edges from staples or metal fastenings and covering them with tape.

Prohibited and restricted items

Royal Mail advises customers to check its prohibited and restricted items list and Country Guides to confirm whether their item can be posted, and to review any specific requirements, including guidance on wrapping and packaging.

Prohibited and restricted items include, but are not limited to: aerosols, alcohol, batteries, crackers, electronic items, lighters, liquids, matches, medicines, nail varnish, paints, perfumes, and perishables.
