METHOD FOR PRODUCING PLASTIC BAGS AND BAGS MADE USING SUCH A METHOD

摘要

During a stage in the production cycle of the plastic bags, for example during the stage in which they are customized by means of printing, the top part of the initially visible faces (103, 203) of each bag (3) - which part is designed to engage with the opening and gripping members - is coated externally with thin layers (1, 1') of varnish having a high coefficient of friction in order to ensure that the opposite faces of the bag are gripped correctly by the said gripping members.
