ABSTRACT:
The present invention relates to a method of automatically forming, filling, and closing reclosable packaging bags based on a film of flexible material, e.g. a thermoplastic material, provided with added-on strips and in particular complementary male and female slideway closure strips, the method comprising the steps consisting in: providing a feed of flexible film; providing a feed of strips; and fixing the strips on the film by heat sealing; wherein: the step of feeding strips consists in providing a tape of flexible material carrying the complementary strips; and the step of fixing consists in heat sealing the tape onto the film prior to feeding the resulting assembly to the tube-forming neck of an automatic machine for forming, filling, and closing packaging bags. The invention also relates to machines for implementing the method and to the resulting bags.
