Description:
TECNOBOND PP-TLA is a random-block polypropylene copolymer modified by maleic anhydride through a new continuous process with high grafting efficiency which guarantees a very low content of free maleic anhydride.

Applications:
TECNOBOND PP-TLA is particularly recommended as tie-layer adhesive in the co-extrusion processes, meltphase thermoforming, cast or blowing film or sheet. TECNOBOND PP-TLA provides outstanding adhesion in the rigid packaging between non—polar layers as PP and polar barrier materials as EVOH or PA. In barrier co-extrusion covalent bonds are formed at TECNOBOND PP-TLA interface with EVOH or PA while entanglements are in melt phase of PP and TECNOBOND PP-TLA.
