Disposable hygiene products properties

PHAs are moisture-resistant and have gas barrier properties similar to the best coated Aims. They have potential use as plastic moisture barriers. Possible markets include mulch Aims, food and agricultural packaging, drink cartons, feminine hygiene products, disposable diapers, and disposable kitchen items, such as plastic Aims which are difficult to separate for recycling. Coatings may be applied with PHA as an amorphous latex which can be either reconstituted from the crystalline form of the polymer or obtained directly from a bacterial suspension by enzymatically dissolving the other cellular components. In the latter case, it... 

Emulsions provide the full range of cost performance properties meeting the various requirements of disposable and permanent non-woven fabrics, e.g. J-cloths, disposable nappies/diapers, feminine hygiene products... 

The properties of the copolymer can be tailored to make it suitable either for molded articles such as shampoo bottles, or thin films for plastic envelopes or carrier bags. However, the polymer is costly, a container made of Biopol being about seven times more expensive than polyethylene. This polymer is now in production and used for packaging, agricultural products, and disposable items of personal hygiene. 

Their physical properties are similar to those of conventional plastics, but they are biodegradable in different environments. Living micro-organisms transform Mater Bi products into water, carbon dioxide or methane. Mater Bi can be used in a wide range of applications such as packaging, disposable items, personal care and hygiene, agriculture and floriculture. 

PLA fibers, because of their natural wicking properties, are finding utility in the diaper and feminine hygiene markets, both in spun bond top sheets and acquisition/distribution layers. Again the ability to replace petroleum-based fibers with enhanced performance with a natural-based fiber has strong consumer appeal. An additional benefit is that since PLA fibers are fully compostable the products can be disposed of by composting if the infrastructure for disposal is in place.
