the present invention relates to hot - coextrudable hot - melt pressure - sensitive adhesives particularly suitable for the production of multilayer films intended for what are called “ repositionable ” packages that are opened and reclosed easily . the films used in these packages comprise at least three layers , namely an outer layer intended to be complexed thereafter , a sealing and separable layer , defining all or part of the internal surface of the package , and between them a hot - melt adhesive layer that joins them together . in this type of package , the adhesive plays an essential role insofar as , once the package has been opened by the end user , the quality of the reclosure and of the reopening will depend on the performance of the adhesive , which is of course a pressure - sensitive adhesive , that is to say an adhesive that adheres simply by manual pressure .
