Developed in collaboration with Amazon, the mailers are made from Mondi kraft paper and open-flute material, and are 100% recyclable in paper waste streams.

Mondi said the packets, available in standard or customised sizes of up to 320mm internal width – the packet height can be adjusted to suit contents size –  are easily printable given the kraft paper construction.

“eCommerce customers are constantly looking for protective, sustainable packaging in which their products are safely delivered to their consumers,” said Nedim Nisic, Mondi group’s eCommerce director. 

“We have risen to this customer challenge with our new fully paper-based solution – the Protective Mailer. This solution can handle any product, both fragile and bulky, from small electronics to books to fashion accessories and much more.”

Mondi’s annual eCommerce report, released in March 2024, found that the majority (58%) of European consumers expect almost all of their parcels to be delivered in recyclable or compostable packaging.

Thais Blumer, Amazon’s European head of sustainable packaging, added: “Amazon stopped using traditional bubble-wrap padded envelopes in Europe several years ago, which presented a challenge to develop light, flexible and fully recyclable paper packaging that provides the same protection.

“Achieving both low weight and maximum protection with a 100% recyclable paper envelope was not an easy task, but these envelopes are easy to pack, simple for customers to recycle at home, and enable damage-free deliveries.”

Mondi employs 22,000 people in more than 30 countries worldwide, with revenues of €7.3bn (£6.1bn).
