Definitions

• the present invention relates to a flexible packaging of weldable material, such as plastic, for storing products, in particular for detergents and cleaners, with a simple opening system having at least one pre-cut, embossed or punched opening aid for tearing, by means of which the packaging simply manually along a defined, in particular straight line tear line can be torn open.
• Flexible packages are known in various designs from the prior art.
• there are flexible, full-surface, space-forming packaging in the form of bag packaging such as bottom bag, flat bag, sealed edge bag, space bag, stable bag or bag.
• the bag in this case forms a filling space in which at least one product in the closed state of the bag is completely enveloped by the bag.
• a closure seam e.g. formed a sealed seam, such as a hot or cold sealing seam, weld or adhesive seam.
• flat bags may have three or four sealing seams corresponding to three or four side edges, depending on the manner of manufacture.
• a tubular bag may include an upper and an opposite, lower outer seam, or an upper and a lower outer seam, and a hull seam, such as an overlapped or folded hull seam.
• the sealed or welded seams are difficult to tear, it is common in such pouches to facilitate tearing, for example, by a notch on one of the welds closing the package.
• This notch is intended to reduce the crack resistance of the weld seams so that the pouch packaging can be opened by tearing without the use of an additional tool such as a pair of scissors.
• the tearing process usually takes place along a tear line, along which the package is separated at least in sections into at least two parts and which leads at least in sections through the filling space of the packaging.
