20210345803 · 2021-11-11 ·

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.

20210339449 · 2021-11-04 ·

A polyolefin multilayer microporous film includes a first layer containing ultra-high molecular weight polypropylene and high density polyethylene, formed on each side of a second layer containing ultra-high molecular weight polyethylene and high density polyethylene. In the first layer, 30% to 60% thereof is a region in which the polypropylene content is less than 20% as determined by AFM-IR from the displacement of an AFM cantilever measured between when laser is irradiated at 1465 cm-1 and when laser is irradiated at 1376 cm-1. For regions wherein the polypropylene content is 20% or higher, the mean of the maximum diameters is 0.1 μm to 10 μm. At 90° C., the film has an elongation at puncture of 0.40 mm/μm or greater.
