ABSTRACT:
The present invention relates to a thermoplastic composition comprising at least one crystalline water sensitive polymer and at least one amorphous water sensitive polymer. The thermoplastic composition may optionally further comprise additional ingredients such as other polymers, tackifying resins, plasticizers, waxes, and mixtures thereof. The thermoplastic compositions are useful in a variety of applications wherein water or moisture sensitive thermoplastic materials are employed such as various packaging adhesive applications including case and carton sealing, remoistenable adhesives, repulpable/recyclable adhesives and multiwall bag applications. The present invention is also useful for moisture activatable reinforcement strings and opening tapes for corrugated containers, as well as for a variety of nonwoven applications such as body fluid impermeable barriers, core stabilization adhesives, and construction adhesives.
