Plastic bag for wrapping flowers and device for producing such bags

摘要

The object to be achieved here is to produce plastic bags for flowers in such a way that the bags can be easily torn open for use. To this end, at least one line of perforations is provided or the weld takes the form of a perforated seam. To achieve this, a device is used which is composed of a rotating shaft which has welding wire placed on it in a helical arrangement, for example; the contact surface (4) of the welding wire is interrupted at least once or exhibits elevations or recesses.
