BAGS AND ROLLS WITH RIBS FOR OBTAINING A HIGHER RESISTANCE AND MICRO PERFORATION FOR REMOVING ODOURS AND/OR VAPOUR FOR ALL TYPE OF PACKINGS AND USES, MADE OF 100 COMPOSTABLE BIOPOLYMER OR POLYETHYLENE.

摘要

The present invention is related to the industrial and commercial sector where bags and rolls with ribs are required for obtaining a higher resistance and micro perforation for removing odours and/or vapour for all type of packings or uses. The ribs may be manufactured lengthwise the film in a calliper different from that of the bag or roll, with different numbers of ribs, depending on the needs. The micro perforations are performed in the film extrusion for avoiding malodours and/or vapour. The invention is intended to reduce the callipers of bags and increase the number of bags per kilo, increasing the resistance thereof and removing maloudours and moisture, thus reducing the volume of rubbish and pollution in the environment. The bags may be manufactured in a 100% compostable biopolymer which complies with the International Standard ASTM-6400, and bioplastics of natural origin, which may be naturally degraded or in a compost, polyethylene may also be used for the manufacture thereo f.
