ABSTRACT:
The present invention relates to an easily separable laminated/perforated film for packings, that can seal the contents under transportation and storage situations and can be formed to the situation for communicating the container interior with the external side when it is to be used.
This laminated/perforated film is the film which has bonded both the films in simulation by providing many perforations onto a formed film and by pressing another film which has been extruded from a film forming machine and which is still in a fused state against this perforated film, and this simulation bonding is to be achieved when the film in the fused state has invaded into the perforations of another film.
