An easily separable laminated/perforated film (10) for packaging to seal the contents has two films bonded together, one film (1) having many perforations (1a) into which is pressed a second film (4) which has been extruded and at the pressing stage is still soft. Portions (1b) of this film thus enter perforations (1a) to form a connection which can be separated as required in use. A base film (16) is bonded by adhesive (12) to the back of film (4). |
