METHOD AND APPARATUS FOR PRODUCING LAMINATED COMPOSITE MATERIAL |
摘要 |
A device and method for forming a moving web of laminated composite material having weakened zones therein from a moving continuous web of relatively extensible plastic film material, having identical sets of graphics printed on nominally constant length repeat length portions thereof which are subject to length variation from a constant design repeat length distance, and a moving continuous web of relatively nonextensible paper material. A method and device for forming a three-layered composite material having weakened zones therein is also described. Carton blanks and liquid tight cartons having tear away tab portions formed from such three-layered composite material are also described. |
