The present method for using a packaging material comprises the application of a coating for covering the defects at the surface thereof using an adhesive substance. This packaging material may include a layer of a polypropylene or cellophane film with a layer of aluminium foil bonded together using the adhesive substance, or several layers of paper with polypropylene, metallised polypropylene or pigmented polypropylene films bonded together using the adhesive substance, wherein one at least of said layers includes printings thereon. The coating may consist of a polypropylene, metallised polypropylene or pigmented polypropylene film with or without printings thereon. It may also consist of simple paper or of paper bonded by the adhesive substance to a polypropylene film with or without printings thereon. The adhesive substance used in this packaging material may consist of paraffin, wax or synthetic glue. This invention makes it possible to use a packaging material that comprises printing or other defects on its front surface, improves the resistance of said material and eliminates the need for methods which are used for destroying bad-quality packaging materials and result in environmental pollution. </p> |
