Finland has developed new ultra-thin packaging materials

Xinhuanet Helsinki, April 7th  Finnish researchers have recently developed a new ultra-thin packaging material, which can be used for packaging of food and medical supplies. The light, thin and sealable performance are better than traditional Metallised film.

Researchers from Finland's National Technology Research Center recently reported that they have developed a new bio-based coating film with the thickness of only 25 nm (1 nm is one billionth of a meter), which is non porous, flexible and bendable, by using the atomic layer deposition technology that can deposit substances on the base layer by layer in the form of a single atomic film. This new packaging material has good impermeability, and is particularly suitable for packaging of food and medical products.

The researchers said that fruit juice, coffee, tea and some drugs have very strict requirements on packaging materials, which must have sealable, moisture resistance, oxidation resistance and other performances. At present, this kind of packaging materials usually use Metallised film as the isolation layer, but the packaging materials containing Metallised film are not only difficult to recycle, but also consume a lot of energy in their manufacturing process.

The researchers said that the research center will have deep research on this new packaging material with a view to putting it into practical production as soon as possible.
