Description
Technical field
The present invention relates to a kind of thin and soft transparent membrane.
Background technology
Along with expanding economy and
the structure of rural undertakingadjustment,
chinathe market demand of all trades and professions to plastic sheeting constantly rises.
Within 2005, the annual whole plastic sheeting production and supply enterprises in whole nation total cumulative output value of industry reaches 79,910,504,000 yuan, increases by 29% than last year, accumulative business unit number 1223, annual accumulative
product sales revenue77,417,653,000 yuan, increase by 25.89% than same period last year, accumulated profit total value reaches 2,384,871,000 yuan.The whole industry per capita sales rate is 488,266.94 yuan.
The whole plastic sheeting production and supply enterprises in the whole nation first half of the year in 2006 total cumulative output value of industry reaches 43,959,811,000 yuan, increase by 17.31% than same period last year, accumulative business unit number 1299, accumulative product sales revenue 44,040,148,000 yuan, 22.11% is increased than same period last year, accumulated profit total value reaches 1,213,127,000 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 output of Chinese Plastics film accounts for
plastic product20% of total make is increase of production one of classification faster in plastic product.From the application of Chinese plastic sheeting (thickness is 0.06mm ~ 0.26mm), consumption is maximum, kind is maximum, most widely used is packaging industry, and its consumption accounts for 2/3, is secondly
agriculturalaccount for 30%, then to have be exactly functional membrane, as
microporous barrier, screened film,
geomembranedeng.Nearly all synthesis in theory
resinall may film forming, but there is economic implications, become commodity, consumption is maximum is polychlorostyrene
ethene(PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET),
polystyrene(PS), ethene/
vinyl acetate(EVA),
polyamide(PA) resin such as.Be suitable for if add in resin matrix
additives for plastics, just can prepare required various functional films.Production method on plastic film industry has rolling process and extrusion molding, and wherein extrusion molding is divided into again and extrudes blown film, extrudes curtain coating, extrudes stretching (also known as post forming) etc., and current extrusion molding is most widely used general, especially for
polyolefinthe processing of film, and rolling process is mainly used in
polyvinyl chloride filmproduction.
Chinese Plastics film industry is in a flourish stage, it is reported, the demand of Chinese Plastics film every year by with more than 9% speed increment.And constantly emerge in large numbers along with various new material, new installation and new process, the plastic sheeting of China will be impelled towards diversification of varieties, customizations and possess multi-functional
complex filmfuture development.

In a preferred embodiment of the present invention, described cast polypropylene is polypropylene of aluminizing.
In a preferred embodiment of the present invention, described crystal type saturated polyester accounts for 40% of the overall component of thin and soft transparent membrane, described aluminum polyester accounts for 30% of the overall component of thin and soft transparent membrane, and described cast polypropylene accounts for 30% of the overall component of thin and soft transparent membrane.
A kind of thin and soft transparent membrane of the present invention, has
physicsstability,
machineryintensity, air-tightness are better, diaphaneity and the higher advantage of glossiness.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Wherein, described thin and soft transparent membrane comprises the crystal type saturated polyester of the superiors, the aluminum polyester of interlayer and undermost cast polypropylene and combines, described crystal type saturated polyester is polyethylene terephthalate, described crystal type saturated polyester accounts for the 37%-41% of the overall component of thin and soft transparent membrane, described aluminum polyester accounts for the 30%-31% of the overall component of thin and soft transparent membrane, described cast polypropylene accounts for the 24%-40% of the overall component of thin and soft transparent membrane, and described cast polypropylene is polypropylene of aluminizing.
Further illustrate, described crystal type saturated polyester accounts for 40% of the overall component of thin and soft transparent membrane, and described aluminum polyester accounts for 30% of the overall component of thin and soft transparent membrane, and described cast polypropylene accounts for 30% of the overall component of thin and soft transparent membrane.
Further illustrating, polyethylene terephthalate, exchanged by dimethyl terephthalate and glycol ester or first synthesize bishydroxyethyl terephthalate with terephthalic acid and ethylene glycol esterification, and then it is obtained to carry out polycondensation reaction.Belong to crystal type saturated polyester, be milky or poly-mer that is light yellow, highly crystalline, surface smoothing has light.Be milky or poly-mer that is light yellow, highly crystalline, surface smoothing is glossy.In wider range of temperatures, have excellent physical and mechanical properties, Long-Time Service temperature can reach 120 DEG C, and electrical insulating property is excellent, even under high-temperature high-frequency, its electrical property is still better, but corona resistance is poor, creep resistance, fatigue durability, rub resistance, dimensional stability are all fine.PET has ester bond, can decompose under strong acid, highly basic and water vapor acting, organic solvent-resistant, good weatherability.Shortcoming is that crystalline rate is slow, and forming work difficulty, molding temperature is high, and the production cycle is long, and impact property is poor.Generally improve its processability and physical property by methods such as strengthening, fill, be blended, obvious with glass fiber-reinforcing effect, improve resin rigidity, resistance to effect of heat, resistance to chemical reagents, electric property and weather resisting property.But still the slow disadvantage of crystallization rate need be improved, can take to add the means such as nucleating agent and crystallization promoter.Add fire retardant and anti-flaming dripping agent can improve PET flame resistance and flame resistance.
Further illustrating, cast polypropylene excellent transparency, thickness is even, and vertical and horizontal performance is even, is generally used as the inner layer material of laminated film.The thickness of common CP P film is generally between 25 ~ 50 μm, and better with diaphaneity after OPP compound, surface-brightening, feel is strong, and general gift packaging bag all adopts this kind of material.This film also has good heat sealability.The thickness of boiling level CPP film is generally between 60 ~ 80 μm, and the thermophilic digestion of ability 121 DEG C, 30 min, fuel resistance, air-tightness are better, and heat seal strength is higher, and general meat Package internal layer all adopts the CPP film of boiling level.The invention provides a kind of thin and soft transparent membrane, have
physicsstability,
machineryintensity, air-tightness are better, diaphaneity and the higher advantage of glossiness.
The specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention, and the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
