As used herein, the term "active" is defined as being able to act on, interact with, or react with a selected material (for example, moisture or oxygen) according to the disclosed concept. Examples of these effects or interactions include absorption, adsorption or release of selected materials.

As used herein, the term "active agent" is defined as a material that (1) is immiscible with the matrix polymer and will not melt when mixed with the matrix polymer and the channeling agent and heated, that is, it has higher than One of the melting points of the matrix polymer or the channeling agent, and (2) acting on, interacting or reacting with the selected material. The term "active agent" can include, but is not limited to, materials that absorb, adsorb or release selected material(s). One of the microparticle forms of the active agent is referred to herein as the "particulate active agent". One of the mineral forms of the active agent is referred to herein as the "mineral active agent". The active agent according to the disclosed concept may be a particulate active agent, but (unless otherwise claimed) the currently disclosed technology should not be considered limited to particulate active agents. However, the currently disclosed technology is particularly suitable for entrained polymers formed from a mineral active material (for example, molecular sieve or silicone).

As used herein, the term "matrix polymer" is a polymer that optionally has a gas transmission rate of a selected material that is substantially lower, lower than, or substantially equal to the gas transmission rate of the channeling agent to the selected material . For example, this transmission rate will be the water vapor transmission rate in an embodiment where the selected material is moisture and the active agent is a water-absorbing desiccant. The main function of the matrix polymer is to provide structure for the entrained polymer. Suitable matrix polymers may include thermoplastic polymers, for example, polyolefins (such as polypropylene and polyethylene), polyisoprene, polybutadiene, polybutene, polysiloxane, polycarbonate, polyamide , Ethylene-vinyl acetate copolymer, ethylene-methacrylate copolymer, polyvinyl chloride, polystyrene, polyester, polyanhydride, polyacrylonitrile, polycure, polyacrylate, acrylic, polyurethane, and polycondensation Aldehydes, or their copolymers or mixtures.

Examples of currently disclosed technology

In one embodiment, the currently disclosed technology includes an injection molded polymer material or composition. In one aspect, the component is formed in the shape of a ball and/or a solid object. The currently disclosed technology contrasts with a non-molded object in the shape of a strip or a film. And as In contrast to a molded part described herein, a strip or film is usually formed of extruded material on a die (not a die). Strips or films are usually formed of very thin polymer materials. Therefore, a molded part is thicker, heavier, and/or denser than a strip or film. Optionally, in any embodiment, the injection molded polymer portion or component is three-dimensional, wherein its smallest dimension is at least 2 mm, optionally at least 4 mm.

In one aspect, the currently disclosed technology is an injection molded polymer component or material containing oil and/or an oil-based product (such as probiotics) and formed into a ball and/or a solid object shape. Packaging or container. One benefit of the currently disclosed technology is that the injection molded polymer component can help stir the mixture in the package or container when shaken and/or will likely be easier to automate handling than an extruded strip or film.

A film or strip will likely provide a moisture absorption faster than a molded desiccant portion. Although this may be desired in some applications, for others (where a long shelf life is required and a desiccant film/strip "uses up" too quickly due to rapid moisture absorption), a film or strip may not be preferable. For example, a solid, molded component is less likely to run out or "run out" too quickly.

In one embodiment, the polymer material or component may be or may include an entrained polymer composition having at least one matrix polymer material and an active agent. In another embodiment, the entrained polymer composition includes at least one matrix polymer material, an active agent, and a channeling agent.

In any embodiment, the matrix polymer material may include a matrix polymer and an optional additive.

Suitable matrix polymers may include thermoplastic polymers, for example, polyolefins (such as polypropylene and polyethylene), polyisoprene, polybutadiene, polybutene, polysiloxane, polycarbonate, polyamide , Ethylene-vinyl acetate copolymer, ethylene-methacrylate copolymer, polychloride Ethylene, polystyrene, polyester, polyanhydride, polyacrylonitrile, polysulfide, polyacrylate, acrylic acid, polyurethane and polyacetal or their copolymers or mixtures.

The additive can be a filler, a colorant, a plasticizer or a stabilizer.

Suitable channeling agents may include polyethylene glycol (polyglycol), such as polyethylene glycol (PEG), ethylene vinyl alcohol (EVOH), polyvinyl alcohol (PVOH), glycerol polyamine, polyurethane, and polycarboxylic acid (Contains polyacrylic acid or polymethacrylic acid). Alternatively, the channeling agent may be, for example, a water-insoluble polymer, such as propylene oxide polymerized monobutyl ether, such as Polyglykol B01/240 produced by CLARIANT. In other embodiments, the channeling agent may be propylene oxide polymerized monobutyl ether (such as Polyglykol B01/20 produced by CLARIANT), propylene oxide polymer (such as Polyglykol D01/240 produced by CLARIANT), ethylene vinyl acetate , Nylon 6, Nylon 66 or any combination of the above.

Suitable active agents according to the disclosed concept include absorbent materials, such as dry compounds. If the active agent is a desiccant, any suitable desiccant can be used for a given application. Generally, physical absorption desiccants are better for many applications. These may include molecular sieves, silica gel, clay, and starch. Alternatively, the desiccant may be a chemical compound that forms water-containing crystals, or a compound that reacts with water to form a new compound.

Optionally, in any embodiment, the active agent may be an oxygen scavenger.

It is believed that the higher the concentration of the active agent in the mixture, the greater the absorption, adsorption or release capacity of the final composition (as the case may be). However, too high a concentration of the active agent may make the entrained polymer more brittle, and make the molten mixture of the active agent, matrix polymer material, and channeling agent more difficult to thermoform, extrude, or injection mold.

In one embodiment, the loading level of the active agent can range from 10% to 80%, including any weight ratio covered by the total weight of the entrained polymer. Subrange or value.

In another optional embodiment, the active agent loading is from 20% to 80%, optionally from 20% to 60%, optionally from 20% to 50%, optionally from 20% to 40%, Optionally from 30% to 80%, optionally from 30% to 60%, optionally from 30% to 50%, optionally from 30% to 40%, optionally from 40% to 80%, Optionally from 40% to 60%, optionally from 40% to 50%.

Optionally, the matrix polymer can range from 10% to 50%, including any sub-ranges or values encompassed by the weight ratio of the entrained polymer. In an optional embodiment, the matrix polymer is not less than 20% by weight relative to the total weight of the entrained polymer, optionally not less than 30% by weight, and optionally not less than 40% by weight. In another optional embodiment, the matrix polymer is not more than 40% by weight relative to the total weight of the entrained polymer, optionally not more than 30% by weight. In another optional embodiment, the matrix polymer can range from 15% to 40% by weight of the entrained polymer, optionally 20% to 35% by weight, optionally 25% to 30% by weight.
