Abstract
The present invention is directed to a film comprising a base film which has been coated on at least one side with a coating that enhances gas and/or moisture barrier properties, wherein the base film comprises a fiber material and at least 60% by weight of said fiber material is microfibrillated cellulose, and the thickness of the coating is from 0.05 to 20 μm. The invention is also directed to products using said film. Such products are in particular packages suitable for sensitive objects that need to be packaged in a controlled or modified atmosphere. The film is also useful for other purposes, such as in the manufacture of balloons.
