Abstract
The process for the manufacture of a tubular semimanufactured article made from plastic (synthetic resin) for the fabrication of sacks comprises at least one tubular extrudate made from a thermoplastic film, said extrudate reinforced with narrow strands or tapes made from plastic or the like and extruded around the circumference and/or along the length thereof, and a second tubular covering or jacket extrudate made from a thermoplastic film which is applied onto said first reinforced plastic film, whereupon the assembly is bonded together in a soft and warm condition. In this connection, said second tubular plastic film is applied in the form of at least one individual, preferably continuously delivered, film run or web, said film run being welded or bonded together at its edges, thus forming the tubular covering or jacket film.
