Problems solved by technology

But all these methods have the disadvantage that when the adhesive is applied on one entire side, the tack level is not high enough since the film must still be able to unroll when packaging the goods
While this packaging material tends to increase tack, especially at the end of the packaging cycle, it suffers from problems with the various parts of the packaging material sticking to each other as it is wound onto the reel during the manufacturing process

Embodiment Construction

[0031] The materials and methods of the present invention will now be discussed with reference to Figures 1-12. Like numbers and names in the drawings indicate like elements.

[0032] Fig. 1 is a perspective view of a packaging material according to an embodiment of the present invention. The packaging material 3 prepared in Figures 1-4 comprises at least two packaging parts 1, 2 having a predetermined length. The packaging material 3 can be made of polyolefin, such as polyethylene or other suitable polymeric material, which is about 40 to 120 microns thick and 50 to 400 cm wide. In addition, the packaging material 3 can also be transparent or colored. However, the materials used for the wrapping parts 1, 2 are by no means limited to the materials mentioned above, but may include netting or other suitable wrapping materials, whether natural or man-made. The length and width of each packaging portion 1, 2 should be sufficient to cover at least the circumference or perimeter ...

Abstract

Method and material for wrapping items using a wrapping material made up of separate wrapping portions of a predetermined length. The wrapping portions are attached and released at their ends using a Z-lock system including a discrete laminate. The discrete laminate of the Z-lock system holds the wrapping portions together during manufacturing but can also easily release or separate the wrapping portions at a desired point in the wrapping process. The separating of the wrapping portions exposes an adhesive that is use to securely bond at least one wrapping portion to the item being wrapped at the end of a wrapping cycle.

Description

[0001] This international application claims priority to U.S. Application No. 10 / 884,966, filed July 7, 2004, and entitled "Packaging Materials Employing a Z-Lock System and Methods of Making and Using the Same," filed in 2002 A continuation-in-part of US Application No. 10 / 326,418, filed December 23, the subject matter of which is incorporated by reference in its entirety. technical field [0002] The present invention relates to packaging materials and methods of using and assembling such packaging materials comprising a Z-lock system which releasably connects predetermined lengths of separate packaging parts, each of which is held at its transverse ends together and apart. Each packaging section constitutes at least one complete packaging cycle. A complete roll of packaging material comprises several packaging parts which are held and separated at their transverse ends. The transverse ends of each packaging portion form a zigzag, creating a Z-lock system. The Z-Lock syst...
