An adhesive composition of general use is described, and particularly suitable for welding plastic parts, in the form of a two-component composition. The first of the two components being a cyanoacrylate based glue, and the second of the two components includes a blend, in powder form, of a polymeric origin component and an organic origin component.

A silane-containing compound having a cyclic structure in a molecular structure; a modified hydrogenated petroleum resin in which a bromine value, a silicon element content, a weight average molecular weight, and a molecular weight distribution are specific values; a modified hydrogenated petroleum resin obtained by subjecting the modified hydrogenated petroleum resin to a condensation reaction; an adhesive composition including the modified hydrogenated petroleum resin; an asphalt composition containing the silane-containing compound or the modified hydrogenated petroleum resin.

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.

A packaging material including a polymeric film surrounding a plastic mass form material. In embodiments, methods include packaging sticky plastic mass form polymers within a polymeric film to prevent agglomeration. Processes include the use of a polymeric film composition that is compatible with the core plastic mass form. The polymeric film can be applied to the plastic mass form through continuous coextrusion, as a film through a hot melt form, fill, and seal process, or as a sealed film bag for inclusion of cooled and coated or uncoated solid sticky plastic material shapes.
