Designing and packaging letters
Correct preparation for smooth processing

Anchor Navigation

Correctly placing the postage paid impression, the recipient and sender addresses, and appropriate packaging ensure optimal and efficient processing as well as reliable delivery to the recipient.

Follow our recommendations for designing your consignment and packing it the ideal way. This protects the content from damage and attracts attention from the recipient while raising curiosity. The packaging guidelines are based on the standards set out by the printing industry.

Plastic packaging and the environment
A better life cycle assessment than paper packaging

Using classic plastic packaging to package goods is currently a hotly debated practice. We are seeing more and more market and public demand for environmentally friendly alternatives, or indeed for deliveries that don’t use any packaging at all. At the same time, recipients expect their parcels to be delivered in mint condition whatever the weather. This is a challenge to all senders.

The life cycle assessment for certain types of plastic packaging is better than for paper packaging. You can find more information, including on Swiss Post’s role when it comes to packaging mail items, in these documents:

Goods in letters

Do you want to send goods such as keys or USB sticks as letters? Always choose secure packaging such as bubble wrap or cardboard envelopes.

Send the goods with additional security as a letter with delivery tracking (A Mail Plus) or as a signed-for letter (registered mail).
