The World’s First Seamless Aluminum Hermetic Tin Cans

Published on October 14, 2025
words by Victoria K.

Hermetic cans are nothing new and have been around since the 1800s. Originally, these hermetic tin cans were made of tin or tin-plated steel and they were mainly used for canning and preserving foods. The air-tight hermetic closure of these tins prevents the outside environment to affect the canned good, significantly increasing its shelf life. According to the U.S. Department of Agriculture, canned foods can remain fresh for decades as long as the hermetic tin itself is in good condition. Because of this, it’s no surprise that canned foods are popular among the military, preppers, and regular ever-day people alike.

In today’s world, hermetic tins are still commonly used for storing and preserving fresh food products. Think for instance about herbs, nuts, coffee, tea, and supplement powders. All these goods need to be stored away in an airtight and dry environment to sustain their original quality. Whereas this on itself is no surprise, what is remarkable is that most hermetic tin cans on today’s market are still made of tin-plated iron – just like they have been for the past hundreds of years. This while the majority of other metal packaging materials have upgraded and changed mostly from tin, steel, and iron towards aluminum. Whereas seamless aluminum tins are common in nearly any industry, it’s still difficult to find a full aluminum seamless hermetic tin can today. Luckily, this is all about the change!

With the introduction of uCan-Packaging’s seamless aluminum hermetic tin cans, a new world opens up for companies who are looking for a premium and environmentally friendly hermetic tin. These are the world’s first hermetic tin cans that are crafted out of 100% recyclable aluminum and feature a sleek and seamless design.
