    Abstract: The invention relates to a ball, comprising a biodegradable polymer and one or more additives, such as an electrostatic charge eliminating additive, a density increasing additive, a strength/hardness modifier and/or the like added to the polymer mass during the compounding step. The ball is manufactured by a process generally applicable to the manufacture of polymers, such as injection molding, into a substantially spherical shape and grinding and/or polishing it to its final shape by means of double-sided lapping, barrel tumbling and/or the like. The biodegradable polymer used in the ball is polybutylene succinate (PBS).

    Abstract: Disclosed are a protective starch-based film and its preparation method and application, belonging to the field of food packaging. According to the method for preparing the protective starch-based film, surfaces of zinc oxide nanoparticles are enabled to adsorb tannic acid and iron ions under the action of metal coordination by controlling the pH to obtain metallic polyphenol network coated zinc oxide nanoparticles, dispersion of the obtained nanoparticles is added to a starch gelatinization solution, and a melanin-like precursor is simultaneously added to form mixed liquid; and by controlling the pH of the mixed solution, π-π stacking, self-polymerization and metal coordination are induced, so that a stable protective starch-based film with a nano-reinforced interpenetrating network structure is formed. The method is simple, green, pollution-free and energy-saving, and the prepared starch-based degradable film has remarkable ultraviolet-shielding, mechanical and antibacterial properties, thus having wide application prospects in the field of food packaging.

    Abstract: Bioplastic compositions containing between 2 wt. % and 25 wt. % of at least one starch, between 40 wt. % and 65 wt. % of at least one plasticizer, and between 1 wt. % to 10 wt. % of at least one acid are used as insulation materials. A method of making a bioplastic composition includes the steps of heating a first aqueous mixture containing at least one plasticizer and at least one acid; adding at least one starch to the first aqueous mixture to produce a second aqueous mixture; heating and mixing the second aqueous mixture to produce a precipitate; and separating the precipitate from residual liquid of the second aqueous mixture to produce a bioplastic composition.
