Wrapper with tear lines for print media access
The granted patent US12043466B2 introduces a laminate media wrapper designed for efficiently wrapping and sealing stacks of print media. The wrapper consists of a laminate structure with two layers, featuring multiple lines of weakness that facilitate easy opening. Specifically, the design includes a first line of weakness extending from the front edge, a second line running parallel to the front edge, and a third line positioned at a non-zero angle between the first and second lines. These lines are strategically placed to guide tearing, allowing for a controlled opening of the wrapper. The first layer is made of oriented polypropylene (OPP), while the second layer is composed of polyethylene terephthalate (PET), and they can be laminated using various adhesive methods.
Additionally, the patent outlines several features that enhance usability, such as printed indicia indicating where to initiate tearing and the option for the first line of weakness to be concealed beneath flaps of the wrapper. The design also allows for variations in the depth of the lines of weakness, which can influence the tearing behavior. The method for opening the wrapper involves gripping and pulling a flap to create an access point for the print media. Overall, the laminate media wrapper is engineered to provide both structural integrity and user-friendly access to the contents, making it a practical solution for packaging print media.
