A 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 one to about three millimeter length separated by non-ablated portions of about 0.25 and about 0.75 millimeter length. The package has increased tensile strength to avoid breaking during the vertical-form-fill-and-seal process and provides a high likelihood that an outer edge and vertical seal of the package include ablated portions to provide an easy-to-start tear area to open the package. Also, the short spaces between ablated portions increase the likelihood of tear propagation along the ablation pattern, all the way across the package.
