Breathability can be defined as the moisture vapour transmission price (MVTR) and it represents the amount of water vapour that passes via a film or a shape over a sure period of time. Coating of lotryl on stable substrates like fabric or non woven may be used to make robust flexible membranes and covers. Breathable films are fashioned with the aid of a aggregate of polymers and mineral fillers. The films have a micro porous structure that is crucial for vapor transmission. The polymers which are specifically utilized are polyethylene, polypropylene, polyurethane, and others which contain polyether block amide, thermoplastic polyester elastomers, co-polyester, and co-polyamide. These films are used in a wide range of end-user industries including building & construction, pharmaceuticals, medical, industrial, food packaging & processing, and personal care & hygiene. In food packaging, the film enables superior circulation of vital gases from the atmosphere keeping the food content fresh and also avoiding accumulation of pungent odors. In case of industrial applications, breathable films are employed to manufacture protective clothing for hazardous environments.
As per MarketsandMarkets, the global market size of breathable films, which was US$2.10 bln in 2015, is projected to reach US$3.21 bln by 2021, at a CAGR of 7.5% between 2016 and 2021. Increasing demand for premium hygiene products in developing countries along with rising per capita GDP, high birth rate, and rising awareness regarding health & hygiene are the factors driving the breathable films market during the forecast period. Hygiene accounted for the maximum share of the market, in terms of value as well as volume, in 2015. Breathable films are used in disposable baby diapers, disposable sanitary napkins, and disposable incontinency adult diapers. These films are used as backsheet materials which provide improved comfort, better skin breathability, and help reduce skin rashes and sores. High birth rate is the major factor driving the baby diapers market, whereas increasing ageing population is fueling the adult diapers market growth. The increasing demand for premium diapers will drive the breathable films market during the forecast period. Polyethylene breathable films account for the maximum share, in terms of value, of the overall market due to its excellent customizability and mechanical properties. There is rising demand for high performance and efficient breathable films, which is expected to drive the market for this segment.
