Abstract: A method for forming a composition that includes mixing an antimicrobially active botanical oil (e.g., thymol, carvacrol, etc.) and a modified starch polymer within a melt blending device (e.g., extruder) is provided. Unlike the problems associated with proteins, the use of starch polymers allows for a greater degree of flexibility in the processing conditions and is still able to achieve good properties in the resulting composition. The present inventors have also discovered that a plasticizer may be employed to facilitate melt processing of the starch, as well as to enhance the ability of the botanical oil to flow into the internal structure of the starch where it can be retained in a stable manner. The composition is also typically generally free of solvents. In this manner, the starch will not generally disperse before use and prematurely release the botanical oil. Due to the water sensitivity of the modified starch, however, it may be subsequently dispersed by moisture when it is desired to release the botanical oil.

Abstract: A film that is both elastic and water-sensitive (e.g., water-soluble, water-dispersible, etc.) in that it loses its integrity over time in the presence of water is provided. To achieve these dual attributes, the film contains an olefinic elastomer and a water-soluble polymer. Although these polymers are normally chemically incompatible due to their different polarities, the present inventors have discovered that phase separation may be minimized by selectively controlling certain aspects of the film, such as the nature of the polyolefin, water-soluble polymer, and other film components, the relative amount of the film components, and so forth. For example, certain water-soluble polymers may be selected that have a low molecular weight and viscosity to enhance their melt compatibility with nonpolar polyolefins. This, in turn, may result in a film that is generally free of separate phases, which would otherwise limit the ability of the water-soluble polymer to contact water and disperse.

Abstract: A meit-extruded substrate (e.g., fiim, nonwoven web, etc.) that contains a thermoplastic starch formed from a starch and plasticizer is provided. The starch and plasticizer are melt blended together in the presence of a weak organic acid (e.g., lactic acid, formic acid, acetic acid, etc.). By selectively controlling certain parameters of the melt blending process (e.g., extrusion temperature, content of the components, etc.), the present inventors have discovered that the starch may be hydrolyzed in a highly efficient manner to form compositions having a comparably lower weight average molecular weight, polydispersity index, and viscosity, which are particularly suitable for use in the formation of melt-extruded substrates.

Abstract: A film that contains a thermoplastic polyurethane and water-soluble polymer is provided. The film is both elastic and water-sensitive (e.g., water-soluble, water- dispersible, etc.) in that it loses its integrity over time in the presence of water. The dual attributes of elasticity and water-sensitivity may be achieved by reducing the tendency of the thermoplastic polyurethane and water-soluble polymer to form separate phases. Namely, phase separation may cause the elastomer to act as a barrier and limit the ability of the water-soluble polymer to contact water and thereby disperse. To minimize such phase separation, a variety of aspects of the film construction may be selectively controlled, such as the nature of the thermoplastic polyurethane and water-soluble polymer, the relative amount of each component, and so forth. For example, thermoplastic polyurethanes are polar in nature and thus may be generally compatible with water-soluble polymers (e.g., polyvinyl alcohol), which are also polar in nature. Further, water-soluble polymers having a relatively low molecular weight and viscosity typically possess better melt compatibility with polar thermoplastic polyurethanes. By carefully controlling the nature of the polymers used to form the film, the present inventors have discovered that a film may be formed that is generally free of distinct phases.

Abstract: A biodegradable and renewable film that may be employed in a wide variety of applications is provided. The film is formed from a thermoplastic composition that contains at least one starch and at least one plant protein. Even at a high renewable material content, the present inventors have discovered that films may be readily formed from plant proteins and starches by selectively controlling the individual amount of the starch and plant proteins, the nature of the starch and plant proteins, and other components used in the film. Balancing the amount of starches and plant proteins within a certain range, for instance, can reduce the likelihood of plant protein aggregation and enhance the ability of the composition to be melt processed. The composition also contains at least one plasticizer that improves the thermoplastic nature of the protein and starch components. The selection of the plasticizer may also help reduce the tendency of the plant protein to aggregate during melt processing. For example, a relatively acidic plasticizer (e.g., carboxylic acid) may be employed in certain embodiments to minimize the formation of disulfide bonds in a gluten protein, and thereby decrease its tendency to aggregate.

Abstract: A film that is both biodegradable and flushable, and yet can still act as a barrier to water or other fluids during use, is provided. More particularly, the film contains a water-dispersible core layer that helps the film to lose its integrity after being flushed, as well as a water-barrier skin layer that helps maintain the integrity of the film during use. The nature and relative concentration of the components in the water-barrier layer are selectively controlled to achieve a combination of different functions. That is, the majority of the polymers employed in the water- barrier layer are biodegradable polymers that can be degraded by microorganisms while in an aqueous environment (e.g., septic tank, water treatment facility, etc.). To even further enhance the overall renewability of the layer, a relatively high amount of the biodegradable polymers are starch polymers, which are also renewable. The starch polymers can also minimize the degree of stickiness in the film, which can sometimes result from certain types of synthetic polymers. Even at a high starch content, the present inventors have discovered that films may still be readily formed by using synthetic biodegradable polyesters in combination with the starch to facilitate melt processing.

Abstract: A thermoplastic starch for use in a melt-processed composition (e.g., fiber, nonwoven web, etc.) is provided. The thermoplastic starch contains an enzymatically debranched starch and a plasticizer. By selectively controlling certain parameters of the enzymatic modification process (e.g., temperature, enzyme and starch concentrations, reaction time, isolation method, etc.), the present inventors have discovered that a native starch may be hydrolyzed in a highly efficient manner to form compositions having a comparably lower weight average molecular weight and viscosity, which are particularly suitable for use in the formation of thermoplastic starches for use in melt processing applications.
