The new envelopes, which have started to land on UK doorsteps , protect deliveries without using any plastic content — unlike envelopes lined with bubble wrap which had been used previously.

Amazon said its customers want rightsized, recyclable packaging that minimises waste and ensures damage-free delivery.

When this is not an option, it optimises the type, material, and weight of the packaging to increase circularity, avoid waste, and reduce carbon emissions — without sacrificing safety or functionality.

This latest design was created to keep products securely in place, while at the same time absorbing stress put on the package during its journey to customers’ homes.

Due to the lightweight lining, the package itself is said to be much lighter than equivalent-sized cardboard boxes, avoiding 44g of packaging per shipment, on average.

The e-commerce giant said the packs are also easy to fill without wasted space due to their greater flexibility, and the fact they don’t require additional padding materials to be added, such as recyclable paper dunnage.

“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,” said Thais Blumer, European head of sustainable packaging for Amazon.

“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.”

The new paper-padded envelope gets its strength from the specially engineered lightweight paper used for the outer package paired with a corrugate inner lining that provides resilience and protection, despite only being a few millimetres thick.

The flexible design of this lining also features multiple ridges, allowing the packaging to fold around its contents in a way that makes it simple and quick to pack.

By preventing goods from shifting inside the package, the envelope safeguards products in transit, until they arrive safely at customers’ homes.

“Together with Amazon, we spent several months testing our designs, evaluating various padding options such as honeycomb and embossed bubble paper. Ultimately, open-flute padding — a flat paper sheet attached to a sheet of ridged paper — proved to be the best solution,” Pedro Cuesta, a packaging engineer from Mondi, explained.
