Process for making a planar substrate, one face of which having anti-slip properties, and the other having adhesive properties, and such obtained substrate

摘要

Process for continuous production of an adhesive nonslip planar substrate, characterised in that it consists: - in unwinding a flexible planar substrate (2) under low mechanical tension; - in coating, at room temperature, one of the two main faces of the said substrate (2) with a coating composition (3) consisting of a thermoplastic resin (27) containing added hollow microspheres (28) the outer coat (29) of which is made of a polymer which is also thermoplastic and the core (30) of which contains a volatile fluid; - in heating the substrate (2) thus coated; - then, in subjecting the substrate on the other opposed main face to coating with a natural or synthetic adhesive (15); - and, finally, after drying of the said adhesive, in storing the product thus obtained. The invention also relates to the nonslip adhesive papers thus obtained. Application: packaging. IMAGE
