    摘要: An easy-opening feature in a flexible package is provided by forming a tear feature in the package material by slitting, perforating, or otherwise forming a stress riser in the material, and affixing a label to the package material so that the label adheres to the tear feature. The formation of the tear feature and affixing of the label are performed prior to wrapping a product in the package material and sealing the material, and preferably are performed while the package material is moving along a path in a packaging apparatus. The label in one embodiment includes a detachable middle portion that tears free of the rest of the label upon pulling the detachable portion, such that remaining portions of the label remain on the package adjacent the opening created by the tear feature.
