Shanghai Daoqin Plastics Co., Ltd.

          market upper has very more plastics container, plastics water 杯, plastics box/case, plastics bottle …… this plastics container is day frequency 繁接触 东西, how 选? its this plastics container upper is has 代号, it is has “身份证”. different 代号代 table/sheet different applications, can need large 意哦!

         plastics container has types?

        每 plastics container has 一 “身份证”, generally in plastics container 底部. this is plastics products recycling 标识, USA plastics industry related machine made 定. this sleeve/set will plastics 材质辨识码打 in container or packaging upper, from 1号 to 7号, 每 编号代 table/sheet types plastics container. plastics container 时, 消费者 can through recycling 标志进行辨认. below/following is commonly used plastics products 代号:

         terephthalic acid ester

            this type of material made as container, is Common water plastics bottle, 也俗称“宝特 bottle ”, heat resistant 至70℃, easy deformation, has for has material melt 出. this type of plastics container can in automotive inner cationic, need 装酒, and other material 质.

          high density polyethylene (PE)

           盛装清洁 agent, 洗发精, 沐浴乳, use 油, and other container more 以HDPE manufacturing. container more semi transparent, 手感似 wax. 不建议 use type container as is water 杯, or use material container other material product, more need ring use.

          polyvinyl chloride (PVC)

            more used for manufacturing water tube/pipe, 雨衣, 书包, building materials, plastics film, plastics box/case and other device material. PVC can property excellent 良, price 便宜, use very 普遍, high temperature easy make has material 质析出, very less by used for food packaging. this category of container difficult easy 残留, need ring use.

          low density polyethylene (PE)

            it combined thermoplastic property molding processing various molding process, molding processing property good.  LDPE main/primary applications is as film product, also used for injection molding products, medical device tool, product and food packaging materials, blow molding in molding products and other. 但LDPE made formed film micro 波炉.

           polypropylene (PP)

            more used for manufacturing water 桶, waste 桶, 箩筐, and micro 波炉 食 material container and other. PP melting point high 达167℃, is can micro plastics box/case, can in fine rear heavy use. need attention/notes, has micro 波炉餐 box/case, box/case 体以5号PP manufacturing, box/case cover/cap other plastics manufacturing. due to other plastics large more can high temperature, can and box/case 体一并放进 micro 波炉.

         polystyrene (PS)

          due to PS吸 water property low, more used for manufacturing building materials, toys, tool, 滚轮, also has speed 食店盛饮 material box/case or one-time property tool, Common 碗装泡面 box/case, fast box/case. PS container can micro in, 以免因 temperature degree high 而释出 chemical material. PS container acid, alkali property material rear, separation understanding 出致癌 material 质. 应避免 use fast box/case 打包滚烫 食 material, use micro 波炉煮碗装方便面.

          other type

           main/primary is polycarbonate (PC) （PC）, Common water 壶, 太空杯, bottle.

         how to 进行挑选?

        选购饭 box/case 时候, lower 面三角 inner most good is 5, 6, 7 its in 一, is safety degree relatively high. box/case if is need hot material, long use, generally is selection 5 or 7 this good plastics. if use box/case is 放凉 食 material, normal temperature material 时, can use price relatively low box/case, basic use is what 材质. if need water this liquid 体, is normal temperature lower need use 5, 6, 7 its in 一. ratio 如1号 plastics, normal temperature lower in 1 year above bottle 子也会释放 has material 质. box/case if need in micro in add hot 话, need is PP plastics, is 5号.

         need good plastics box/case has loss or 划痕. generally box/case is resistant use add formed separation, 改良饭 box/case physical properties. if has loss, has comparison deep or 划痕数 amount very more 时候, need 购买.

         also has which can selection?

        随 人们生 active water improve/increase and environmental protection 健康意识 reinforcement, large for plastics container requirements 也越 越 high, use food need environmental protection, food that 也 美观 good 看. therefore, plastics 界也一直奔走 in development new product upper.

        丹麦 food packaging production 商Faerch Plast and Colpac and new 鲜方便食 material manufacturing 商Bakkavor共同 is R&D new material packaging container. need small this container, it is crystallization type PET and hard sheet/plate mixed combined made formed, can make type food in 陈列于 high temperature 存储台之 front add hot. and standards CPET product versus ratio, this type of container decrease/reduce 30% 材 material, but also inner outer pallet and hard sheet/plate or plastics is full can recycling.

         Germany 拜罗伊特 large research small utilizing in 提取 苎烯 oxidation material and oxidation carbon combined formed, obtain types is PLimC polycarbonate (PC) material. PLimC heat resistant, transparent, strong/high degree high, and generally polycarbonate (PC) different in 于不含 has material di 酚A. utilizing this type of material made formed plastics bottle, plastics bag or other container, large can use.

         in addition, already obtain 商业化 application also has PETG plastics. this category of plastics container in product and 人护理 product packaging has good application outlook/prospects. it advantages in 于: surface gloss, 手感舒适, tool has color color and transparent color 调, chemical resistance, impact resistant and tough property good, resistant UV处理, transparent property 依旧不变. its easy processing, can recycling use and environmental protection and other property can, more combined production requirements, can to currently 消费者 for product outer packaging high requirements.

         in production plastics container raw materials in add ratio/proportion nano material, can improvement plastics container chemical property can, especially is retardant property, chemical resistance and UV resistant and other property can has relatively large improve/increase, container tough property to add strong/high. this category of material can use made 啤酒, product packaging bottle.
