摘要:
The invention relates to hot-coextrudable thermofusible self-adhesives that are particularly suitable for producing multi-layer films intended to be used for easy-to-open and easy-to-reclose repositionable packaging containers. Said adhesives comprise a mixture of a styrene block copolymer and a compatible tacky resin having a high melt viscosity and a traction resistance force at 1 m.s . included in the area located below the polynomial curve defined by y = - 2.82.10 .x + 5.92.10 .x 4.97.10 .x +2.15.10 .x 4.99.10 .x + 6.26.10 .x + 4.71.10 wherein the y ordinate represents the constraint which is expressed in MPa and x, abscissa, represents the deformation which is expressed in %.
