Unit.
The whole nation whole plastic sheeting production and supply of the first half of the year in 2006 enterprise total cumulative output value of industry reaches 43,959,
811000 yuan, 17.31% is increased than same period last year, add up business unit's number 1299, add up product sales revenue 44,040,148
Thousand yuan, 22.11% is increased than same period last year, accumulated profit total value reaches 1,213,127 thousand yuan.The sales rate per capita of the whole industry is
889,069.85 yuan.All in all, the management state of national plastic sheeting production and supply enterprise is good.
The yield of Chinese Plastics film accounts for the 20% of plastic products total output, is that increase of production is faster in plastic products
One of classification.From Chinese plastic sheeting（Thickness is 0.06mm~0.26mm）Application field see, consumption is maximum, kind at most,
Most widely used is packaging industry, and its consumption accounts for 2/3, next to that agricultural accounts for 30%, then it is exactly functional membrane to have, such as microporous barrier,
Screened film, geomembrane etc..In theory nearly all synthetic resin all may film forming, but with economic implications, as commodity, use
Amount maximum is polyvinyl chloride（PVC）, polyethylene（PE）, polypropylene（PP）, polyethylene terephthalate（PET）, polyphenyl
Ethene（PS）, ethylene/acetic acid ethene（EVA）, polyamide（PA）Deng resin.If adding suitable plastics in resin matrix to help
Agent, it is possible to prepare required various functions film.Production method on plastic film industry has rolling process and extrusion molding,

General, especially for the processing of polyolefin film, and rolling process is mainly used in the production of some polyvinyl chloride films.
Chinese Plastics film industry is in a booming stage, it is reported that, the demand of Chinese Plastics film is every
Year will be increased with more than 9% speed.And as various new materials, new equipment and new technology are constantly emerged in large numbers, China will be promoted
Plastic sheeting is towards diversification of varieties, customizations and possesses multi-functional composite membrane direction and develops.

With the advantage of comfortableness.
Specific embodiment
Presently preferred embodiments of the present invention is described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly being defined so as to be made to protection scope of the present invention.
Wherein, described temperature-sensitive waterproof moisture-permeable film includes basement membrane and filling perforation material, and the basement membrane includes nanofiber parent
Water layer and polyurethanes, the nanofiber hydrophilic layer are made up of hydrophilic polymers through electrostatic spinning, described base
Film accounts for the 51%-58% of temperature-sensitive waterproof moisture-permeable film totality component, and described filling perforation material accounts for temperature-sensitive waterproof moisture-permeable film and totally divides
The 42%-49% of amount, the height at the hydrophilic aspect peak of nanofiber is 0.6 μm -10 μm, and thickness is 10 μm -50 μm, draws and splits by force
Degree position 1.5N/cm, elongation is 50%-300%.
Further illustrate, the filling perforation material is shape memory polyurethane, described basement membrane accounts for temperature-sensitive waterproof moisture-permeable film
The 56% of overall component, described filling perforation material accounts for the 44% of temperature-sensitive waterproof moisture-permeable film totality component.
Further illustrating, nanofiber hydrophilic layer is that a kind of nanometer for synthesizing compounding containing many nano-components is applied
