A method of encapsulating content with calcium alginate membrane to form a capsule. The method includes embedding sodium alginate into a traditional gelatin ribbon used in gelatin encapsulation, adding calcium to a fill material, encapsulating the fill material, and then denaturing the gelatin in the shell. An exemplary use of this method is to form throwable paintballs; however, other products could be formed using this process. A paintball formed by this process is also disclosed.

The present invention relates to: an ink-receiving layer composition for a decorative member, the composition comprising an acrylic emulsion, a metal salt, and organic particles or inorganic particles; a decorative member comprising a base layer, a printing layer formed on the base layer, and an ink-receiving layer disposed between the base layer and the printing layer and formed of a composition comprising an acrylic emulsion, a metal salt, and inorganic particles; and a method for manufacturing a decorative member, the method comprising a step for preparing a base layer in a flat state, a step for coating a composition comprising an acrylic emulsion, a metal salt, and organic particles or inorganic particles on the base layer, a step for drying or UV curing the coated composition to form an ink-receiving layer, and a step for forming a printing layer on the ink-receiving layer.

The present disclosure relates to a modified environment-friendly corn starch adhesive, comprising the following components in parts by weight: 30 parts of corn starch, 300-400 parts of water, 0.2-3 parts of oxidant, and 80-120 parts of polyvinyl alcohol, 1-5 parts of cross-linking agent, 3-5 parts of calcium chloride, 0.1-3 parts of urea, 0.2-0.5 parts of defoamer, and an appropriate amount of sodium hydroxide (to adjust pH), the cross-linking agent is a modified boric acid cross-linking agent prepared by reacting boric acid with epichlorohydrin, water and citric acid at 80-100° C. The surface of the modified boric acid cross-linking agent is bonded with a large number of epoxy groups and carboxyl groups, which can react with the carboxyl and aldehyde groups of the oxidized starch. These reactions can form synergistic effect with boric acid, which together improve the bonding efficiency and improve the adhesive strength of the colloid.

A biodegradable and substantially water-soluble thermoplastic polyvinyl alcohol-based diverting agent is provided which comprises pellets of a specified polyvinyl alcohol optionally with certain specified additives, which pellets are made in an extruder and cut to a specified size.

An icephobic coating composition forms a coating layer that melts ice and snow upon contract and remains durable after several exposures to winter storms. The icephobic coating composition includes about 2.5% to about 12.5% by weight of latex polymer solids; about 30% to about 70% by weight of an inorganic halide salt; about 15% to about 50% by weight water; and about 1% to about 15% by weight of an organic co-solvent selected from glycerin, glycols, and glycol ethers. An alternative icephobic coating composition includes about 1% to about 20% by weight of a solution polymer instead of a latex polymer, and about 10% to about 40% by weight of a VOC-exempt organic solvent instead of the foregoing water and co-solvent.
