Abstract

1. A process for the production of a tubular semimanufactured article made from plastic (synthetic resin) for the fabrication of sacks and other receptacles, said process comprising the steps of : extruding an inner tubular extrudate of a thermoplastic film ; applying to said extrudate reinforcing tapes or strands of a synthetic resin or other material around the circumference and/or along the length thereof ; extruding at least one second tubular extrudate of thermoplastic film around said first tubular extrudate and said reinforcement layer, characterized in that said strands of film (11), serving as reinforcement, are applied with large gaps between one another to said inner tubular film (10), and the assembly is covered by an outer tubular film (11') ; and, while said inner (10) and said outer tubular extrudate (10') are in a soft and warm condition, bonding them directly to one another through said gaps (101) in said reinforcement (11).
