Abstract: Amorphous propylene-ethylene copolymers are described herein that can include high amounts of ethylene and exhibit desirable softening points and needle penetrations. The desirable combinations of softening points and needle penetrations in these propylene-ethylene copolymers allow them to have a broad operating window. Due their broad operating window, the propylene-ethylene copolymers can be utilized in a wide array of applications and products, including hot melt adhesives.

Abstract: A hot melt adhesive made from a blend of a polypropylene-based polymer, a polyolefin elastomer, and an amorphous polyolefin. These adhesives exhibit excellent molten and pre-set flow allowing them to wet out substrates yet develop properties needed to form and maintain strong bonds making them useful for hygiene, construction, and packaging applications.

Abstract: A flexible carrier for carrying a plurality of containers, such as soft drink and other beverage containers, is formed from a polymer composition which provides the carrier with improved recovery, tensile strength and tear resistance. The polymer composition includes about 40-60% by weight of a low density ethylene polymer having a density of about 0.910-0.950 grams/cm3 and about 40-60% by weight of a post-consumer recycled product blend of low density polyethylene polymer and linear low density polyethylene polymer.
