METHOD AND APPARATUS OF LASER SCORED PACKAGING

摘要

PROBLEM TO BE SOLVED: To provide a package with increased tensile strength so as to avoid breaking during the conventional vertical-form-fill-and-seal process, and a high likelihood that the tear will propagate and an outer edge and a vertical seal of the package includes an ablated portion to provide a user an easy-to-start tear area to open the package.

SOLUTION: The package formed via a vertical-form-fill-and-seal process includes a web material with edge portions sealed to create a vertical sleeve. The package also includes a first sealed end and a second sealed end at either end of the vertical sleeve to create a sealed package. The package includes a laser scribed ablation pattern extending across the web material with ablated portions having an about 1 to about 3 mm length separated by non-ablated portions of about 0.25 and about 0.75 mm length.
