Triplast 170 x 245mm Bubble Padded Envelopes

These white bubble padded envelopes from Triplast are built for anyone who regularly posts parcels, whether that's selling online, sending gifts, or shipping small equipment. Each envelope has an internal size of 170 x 245mm and a bubble wrap lining bonded to the inside of a white paper exterior, giving your contents a cushioned layer of protection against knocks in transit. A peel and seal adhesive strip along the flap means envelopes can be sealed securely by hand, with no need for extra tape.

This listing covers a pack of 20 envelopes, a practical quantity for topping up packing supplies at home or in a small home-based business, and pairs well with a roll of bubble wrap for anything that needs a bit more padding before it goes in the envelope.

Frequently Asked Questions

What size items fit inside these envelopes?
The internal dimensions are 170 x 245mm, which comfortably fits A5-sized items such as paperbacks, small gift boxes, phone accessories, and similar small parcels.
How do you seal the envelope?
Each envelope has a peel and seal adhesive strip built into the flap. Simply peel off the backing strip and press the flap down to create a secure seal without needing tape.
Will these qualify for Royal Mail's Large Letter rate?
That depends on what you put inside. Royal Mail's Large Letter rate has a maximum thickness of 25mm, so slim contents may qualify, but anything bulkier will need to be sent as a Small Parcel. Check your contents against Royal Mail's current size guide before posting.
Are the envelopes padded on both sides or just the back?
The bubble wrap lining runs across the inside of the envelope, giving all-round cushioning rather than a single padded panel, so contents are protected on the main faces of the envelope.
Can I reuse the envelope for a return?
The peel and seal strip is a one-time adhesive, so once sealed the envelope can't be reliably resealed for a second use. For returns, a second envelope or some parcel tape over the original seal is recommended.
