Abstract
There are disclosed polyolefinic films carrying two coatings, the first coating consisting of amino compounds and the second of a mixture of vinyl or vinylidene polymers or copolymers, epoxy resins and microcrystalline waxes, and which films, by virtue of the coatings, are readily thermoweldable, impervious to gases and vapors, and have improved resistance to sticking to the bars of conventional automatic and semi-automatic welding machines. A process for preparing the new polyolefinic films is also disclosed.
