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.

The present invention relates to a thermoplastic resin composition containing a base polymer containing a propylene-based polymer (A) in which a melting endotherm (ΔH-D) is 0 J/g or more and 60 J/g or less, and a melting point (Tm-D) is not observed or is 0° C. or higher and 120° C. or lower; and a propylene-based polymer (C) in which a melting endotherm (ΔH-D) is 20 J/g or more and 120 J/g or less, and a melting point (Tm-D) is higher than 120° C., the content of the propylene-based polymer (C) being 0.5 parts by mass or more and 100 parts by mass or less relative to 100 parts by mass of the content of the propylene-based polymer (A).

The present invention relates to drinking straws that are made from biodegradable material or bioplastics. The process to manufacture the present invention can use waste lipid wax byproducts. The present invention can incorporate chemical modification of corn or hemp fiber waste, and is comprised of wax byproduct, xanthan gum, carnauba wax and stearic acid. Stearin, hardener and plasticizers are mixed with corn or soy wax. A binder ingredient can be added to the waxes and fiber mixture, resulting in a smooth and hard, durable and biodegradable material with a high melting point. This material is then processed using an extrusion method, whereby the mixed ingredients are forced through an opening in a perforated plate or die with a design specific to form a straw, and then cut into a specific size by blades. The extruder consists of a large, rotating screw tightly fitting within a stationary barrel, at the end of which is the die. Extrusion enables mass production of food via a continuous, efficient system that ensures uniformity of the final product.
