Films, packages, and their manufacturing methods

Patent name Films, packages and their methods of manufacture Patent applicant UCB Company Principal Applicant Address Brussels, Belgium Inventor Jonathan Hewitt; Peter Mills Application (Patent) No. 02804724.9 Date of Application 2002.01.07 Certification Date Approval Notice No. 1556767 Auditing Announcement Date 2004.12.22 Instruction CD-ROM D0451 Main Classification Number B65D75/58 Classification No. B65D75/58; B65D65/02 Sub-item Original Application No. PRIORITY AGREEMENT Abstract The present invention discloses a flexible, oriented film (301), which is a substitute for a packaged tear film, having at least one tear line (307, 309) or pattern (preferably: weaker than the surrounding film) on the film (301) along the line and/or When the pattern initiates tearing, the film is substantially torn along the lines and/or the pattern, characterized in that the thickness (specification) of the lines (307, 309) or the pattern is substantially in the direction perpendicular to the film surface and the film The remaining parts are the same; and/or the orientation (degree and/or direction) of the film material along the lines and/or patterns is substantially different (preferably higher orientation) from the rest of the film . The means for forming the lines (307, 309) or pattern is preferably a laser (eg CO#-[2] infrared laser) whose power is set low enough so that the material is not burned along the lines or patterns, but Its power is sufficient to perform reorientation of the material along the line or pattern. The present invention also discloses a method of making the film (301) and the wrapper (721) (eg, a cigarette box), wherein the wrapper is wrapped by the film (601). SATIVALY CLAIMS 1. An optionally flexible polymer film having at least one line and/or pattern thereon, characterized by the orientation of the material in the line and/or pattern and the remaining material on the film. Basically different.
