Shanghai Daoqin Plastics Co., Ltd.

   plastics film is use polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS) and other resin made formed film, used for packaging, and used as film 层. lower analysis large plastics film applications:
  
    PVA coating high retardant plastics film applications
  
    polyethylene (PE) alcohol high retardant composite/compounding film, is 以 polyethylene (PE) plastics is 基材, will modified polyethylene (PE) alcohol water solvent property liquid coating in upper formed tool has high retardant property film. due to polyethylene (PE) alcohol high retardant composite/compounding film tool has good retardant property can, combined environmental protection requirements, therefore, types packaging materials market outlook/prospects separation light 明, in food industrial in has vast market 空间.
   
    di toward tensile polypropylene (PP) film （BOPP） applications
   
    di toward tensile polypropylene (PP) film is 20世纪60 year development 起 一 types transparent soft packaging materials. it is use production will polypropylene (PP) raw materials and function property additives mixed combined, melt mixing/compounding, made formed sheet/slice 材, rear through tensile made formed film. BOPP film not only tool has PP resin has density low, resistant property good, heat resistant property good advantages, but also film optical property can good, machine strong/high degree high, Raw Materials 源丰富.
   
    in addition, also can used for made electrical film, micro film and other high add value function property product, therefore BOPP film development outlook/prospects separation vast. to 2004 year is 止, 我国BOPP film production production capacity is 190 10,000 tons, output/production volume is 176 10,000 tons.
   
    low density polyethylene (PE) film （LDPE） applications
   
    low density polyethylene (PE) is in high pressure lower, ethylene free radical polymerization obtain combined formed resin, also 称“ high pressure polyethylene (PE) ”. LPDE is upper belt/tape has long short different 支链 支链 type separation 子, in upper 每1000 carbon 原子约 belt/tape has 15～30 乙基, or more long 旳支链. due to separation in has relatively more long short 支链, therefore product density relatively low, soft/flexible, low temperature resistance property, resistant impact property relatively good, tool has good chemical stability property, generally lower resistant acid (remove strong/high oxidation property acid outer), resistant alkali, salt type function, tool has good electrical insulation property can.
   
    low density polyethylene (PE) film application areas separation 广泛, ratio packaging field/area. polyethylene (PE) packaging film types type more, its property can has 差异, mono film property can mono 一, composite/compounding film property can 互补, formed is food packaging main/primary material. its 次, polyethylene (PE) film also application in engineering field/area, ratio 如土工 film. it in engineering in can to anti water function, tool has low property. upper application is film, can separation is film, film, cover/cap film, film and other.
   
    polyester film （PET） applications
   
    polyester film (PET)俗称 polyethylene terephthalate (PET), is types thermoplastic property engineering plastics. using/adopting extrusion method made formed thick sheet/slice, again di toward tensile made formed film material. polyester film features is mechanical properties excellent 良, rigid property, hardness and tough property high, resistant 穿刺, resistant scratch, high temperature resistance and low temperature, chemical resistant product property, oil resistant property, gas property and property good, is commonly used retardant property composite/compounding film 基材之一, resistant electrical property good. polyester film price relatively high, thick degree generally is 0.12mm, commonly used packaging food packaging outer material, printing property relatively good. due to polyester film complex property and difficult 判断, to 海关 监 tube/pipe belt/tape 一定 困 difficult.
   
    nylon plastics film applications
   
    nylon Scientific Names is polyamide (PA) (PA), currently industrial production nylon product types very more, its in use production film main/primary product types has nylon 6, nylon 12, nylon 66 and other. nylon film is types non tough film, transparent property good, tool has good gloss, resistant strong/high degree, tensile strength relatively high, also tool has relatively good heat resistant property, resistant property, oil resistant property and resistant has machine solvent agent property, wear resistance, resistant property excellent 良, comparison soft/flexible, retardant oxygen property excellent 良, for water gas retardant property relatively 差, 吸潮, wet property relatively large, hot property relatively 差, suitable for packaging hard property material product, 例如油腻 property food, products, food, true packaging food, food and other.
   
    polypropylene (PP) film （CPP） applications
   
    film is through melt 流延骤 cold production types tensile, non toward film. it features is production speed degree fast, output/production volume high, film transparent property, gloss property, thick degree uniform property good, property can balanced property excellent. due to is film, rear as printing, composite/compounding and other is 方便, widely used in textile product, 鲜花, food, day use product packaging.
   
    aluminum plastics film applications
   
    aluminum film has plastics film features, also tool has metal features. film surface aluminum function is light, anti outer 线照射, long inner material shelf life, also improve/increase film degree, from 一定程 degree upper aluminum 箔, tool has 价廉, and relatively good retardant property can. therefore, aluminum film in composite/compounding packaging in application separation 广泛, main applications dry and other drying, food packaging, and 一 医药, product outer packaging upper.
