A tackifier composition comprising at least one thermoplastic hydrocarbon resin and an antioxidant composition is provided; wherein a portion of the volatile organic compounds in the thermoplastic hydrocarbon resin has been removed; wherein the antioxidant composition comprises at least one primary antioxidant and at least one secondary antioxidant; and wherein the levels of individual volatile organic compound monitored in the tackifier composition are less than about 0.5 ppm as measured by GC/MS headspace analysis. Processes for producing the tackifier composition are also provided as well as adhesives comprising the tackifier compositions.

An adhesive composition contains an acid anhydride group-containing oil or fat (A) and a curing agent (B) having a reactive group reactive with an acid anhydride group. A laminate is obtained by placing an adhesive layer between a first substrate and a second substrate, and the adhesive layer includes the aforementioned adhesive composition. A package is obtained by forming a bag from a laminate obtained by placing an adhesive layer between a first substrate and a second substrate, and the adhesive layer includes the aforementioned adhesive composition.

A hot melt adhesive uses a blend of polymers having controlled stereoerror and comprises a stereoblock polypropylene comprising a first block having an isotactic index of between about 50% and about 95% and a second block having an isotactic index of between about 5% and 50%, wherein the difference between the isotactic indeces of the first block and the second block is at least about 10%. The hot melt adhesive exhibits improved peel and tack properties without compromising shear strength and vice versa.
