Reusable single or multi-layer material, with gas barrier properties and resistance to moisture, as well as processes for its production

摘要

Single or multi-layer material, with barrier properties against humidity and gases and, possibly, against light, which is recyclable, i.e. its components can be fully reused In the production of further material with the similar properties. Basically the material is produced from cellulose pulp or, rather, from sheets of paper or cardboard which are impregnated with a gel forming hydrocoloid sol or with a mixture of hydrocoloids, after which the cellulose-hydrocoloid compound is dehydrated and cooled down. The resulting material can be used, among other applications, in the production of packages to contain goods or other substances, coatings for construction, such as roofs and the like.
