PACKAGE, SUCH AS A BAG, WITH ORIENTED TEAR-OPENING

摘要

Product package, typically a sachet (1) with two side walls (2), a base (17) and an opening (13) through which it is filled before sealing, is made from a material such as a plastic that can be torn manually and has a notch (4) at the end of its tear line. Each of the sachet's two side walls has at least one reinforcing element (50) along the tear line, designed so that the force required to extend the tear line is less than that needed to tear the adjacent barrier. The notch (4) is located in the upper portion of the sachet, typically at a distance of less than 10 mm from the reinforcing element, and the side walls also have guides (61) that prevent the tear from going more than 20 mm from the line of the reinforcing element.
