Films comprising alpha-olefin polymers, such as normally solid polypropylene consisting essentially of recurring propylene units and having a substantial crystalline polypropylene content, and in particular isotactic polypropylene, are rendered easily thermoweldable and/or impervious to gases and vapors, and also given improved resistance to sticking against the welding bars of automatic and semi-...

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 a...

1. A mask for copying documents, made from a single sheet of material folded in such a manner as to form a lower backing surface (15) and an upper, overlay, surface (20), the fold forming a spring hinge (11), characterized by the fact that the upper surface (20) is flat and the fold such that, as the material curves back upon itself, a linear gripper strip is formed between the upper and lower sur...

Articles coated with multilayers of a composition of polytetrafluoroethylene plus a specified proportion of copolymers of perfluorinated polyvinyl ether and tetrafluoroethylene, to which is optionally added a heat stable polymer with a glass-transition temperature greater than or equal to 130 DEG C., are found to have improved durability. The proportion of the copolymer in each layer varies such ...
