Eco Friendly Padded Envelopes

What Are Enviroflute Padded Envelopes?

Enviroflute padded envelopes are paper-based padded mailers designed to give cushioned protection to small items in transit without the plastic bubble lining used in standard padded envelopes. The envelope arrives flat, opens easily, and seals with an Easy Peel closure that uses Deadlock Adhesion so the seal cannot be peeled back without showing it. Once sealed, the padded lining shields the contents from the impact of being stacked, sorted and moved through the courier and Royal Mail networks.

Enviroflute is branded as the world’s most environmentally friendly padded envelope, so it is an eco-friendly, practical replacement for plastic-lined padded mailers in most business uses. The outer envelope is white, giving a clean, professional finish without needing a printed wrap or additional sleeve.

Eco Padded Envelope Sizes

Enviroflute envelopes are sized to match common padded mailers used across the industry. The size labels refer to the internal dimensions of the envelope; the external dimensions are approximately 20mm larger in both directions to allow for the padded lining.

Size A is the smallest in the range, suited to small items such as jewellery, fixings, USB sticks and small electronics. Packed in 200s.

Size C suits paperback books, larger jewellery, cosmetics, tubes of cream and similar small parcels. Packed in 200s.

Size D suits hardback books, branded packaging boxes for smaller products, A5 documents and items of a similar footprint. Packed in 200s.

Size E suits larger books, vinyl records, framed prints and items of a similar size. Packed in 200s.

Size F is the largest standard size in the range, suited to A4 documents, photo books, larger cosmetics sets and packaged homeware. Packed in 100s.

Common Uses for Eco Padded Envelopes

Eco padded envelopes are used across e-commerce and direct-to-consumer despatch for any small, lightweight item that needs cushioned protection but does not need a full cardboard box. Online jewellery, cosmetics, skincare, beauty, fixings and small-electronics retailers use them as their standard mailer for product sizes that fit. Independent book retailers and second-hand booksellers use them for paperback and hardback orders, where the padding protects corners and edges from the bruising caused by sorting machinery and stacking in delivery vans.

Subscription box and gifting brands use them when an item is small enough that a full box would be over-specified, particularly where the white outer envelope can be paired with a printed product card or branded sticker for a presentation finish. The padded lining also resists damp ingress to a useful degree, which matters for items that may sit on a doorstep before being collected.

Why Use Eco Padded Envelopes Instead of Standard Jiffy Bags?

A standard jiffy bag or bubble mailer uses a plastic bubble lining inside a paper or polythene outer, which means the envelope cannot be recycled through normal household paper recycling and the plastic component takes a long time to break down if it ends up in landfill or the wider environment. Enviroflute uses a paper-based padding inside a paper outer, so the whole envelope can go into household paper recycling after use.

Beyond the recycling story, the practical performance is very similar. Enviroflute envelopes give cushioned protection against drops, knocks and the bruising of automated sorting in the same way a plastic-lined padded mailer does. The Easy Peel closure with Deadlock Adhesion also gives a more professional, tamper-evident seal than the self-seal strips used on many cheaper jiffy bags. For businesses looking to remove plastic from their packaging supply chain without compromising on protection, Enviroflute is one of the cleanest switches available.

Eco Padded Envelope FAQs

Q: Are Enviroflute padded envelopes recyclable?


Yes. Both the outer envelope and the inner padding are paper-based, so the whole envelope can be recycled through standard household paper recycling. There is no plastic bubble lining to separate out before recycling.

Q: What size padded envelope do I need?



Size A suits small items such as jewellery and fixings; Size C fits paperback books and small cosmetics; Size D fits hardback books and A5 documents; Size E suits larger books and vinyl records; and Size F fits A4 documents and larger items. The size labels are internal dimensions, with the external dimensions approximately 20mm larger in both directions. If you are not sure which fits, request a sample first to check.

Q: Is there a Size B?

No. Enviroflute padded envelopes are supplied in sizes A, C, D, E and F, skipping B. The available range is consistent with the size tiers used by other padded mailer suppliers.

Q: Can the envelopes be used through Royal Mail and standard couriers?


Yes. The envelopes are designed for transit through the normal Royal Mail and courier delivery networks. The padded lining absorbs the bruising bumps, drops and scrapes typical of automated sorting, and the Easy Peel closure with Deadlock Adhesion provides a secure, tamper-evident seal in transit.
