the invention relates to a continuous band for producing bags for fruit and vegetable products , formed from a continuous plastic sheet which has been die - cut to produce a series of small holes which are closed using mesh or net fragments fixed along the periphery of said holes by means of heat - sealing , gluing or any other conventional means . according to the invention , the area of the continuous sheet intended to contain the handle is provided with a transverse patch of pre - determined hardness in order to reinforce the area used to hold the bag once it has been filled , such that the thickness of the band - forming plastic sheet can be significantly reduced , specifically by a value of the order of 40 %, without affecting the performance of the bag in terms of mechanical strength since the area in which the greatest strains are concentrated corresponds exactly to the area containing the handle .
