      polystyrene (PS) (PS plastics raw materials ) usually by as is used for blow molding film resin. machine 供货商不 sales used for blow molding polystyrene (PS) plastics raw materials film equipment, resin 供货商也不 provide blow molding film product grade polystyrene (PS) resin, 甚至流延 film product grade very less. 但事实 upper, polystyrene (PS) not only can by blow molding formed high quality film, but also already tool has year production history. from 1960 year 代以, general purpose polystyrene (PS) in through modified, in full standards equipment upper 进行商业 property blow molding, to film. 不 你 very less to about/regarding plastics raw materials it 情况, causes is this as 人们总 is maintain 沉默. this 样做 理由 can can is this type of low cost resin already to high add value application methods, for/regarding less from this category of application 人们, can obtain versus can 观 利益. polystyrene (PS) is tool has rigid 挺, transparent and can printing property can, therefore in mono and more blow molding film field/area to it combined 适 位置. it has very good property, and it gas 体传送 or "透 gas property " for new food packaging is tool has 越 越 large force features.

       blow molding polystyrene (PS) film ultra- 越流延 film advantages
in it use is machine, add upper more easy orientation, and can manufacturing thin more product. 例如, in 俄亥俄州Hebron Dow company material products 部, blow molding production thick degree is 1 to 10mil(25.4μm) Trycite polystyrene (PS) film; in large New Castle Avpex国际 company blow molding 1至4mil polystyrene (PS) film, 而流延 polystyrene (PS) film thick degree ultra- 4mil. blow molding polystyrene (PS) film also has this advantages, is it can made formed light or has gloss surface, 而流延 film can made has gloss film. 像流延 film 一样, blow molding polystyrene (PS) film can to very high transparent degree, is, it and styrene - butadiene polymer blending, degree increase, film 就会变 不 that transparent. polystyrene (PS) used as blow molding resin has disadvantages. its is difficult processing, especially in used as mono material 时. polystyrene (PS) in as is polyolefin in 间层时, processing relatively small. about/regarding how to this as technology very less - 仅 has 一二篇TAPPI or SPIANTEC论文 and in Europe 出版 文章, full is 1980 year 代. currently make used for processing equipment full is patent processing in company internal assembly. machine 供货商建造 一 商业 production 线, or production 线 一部 separation, is has 专门 客户 specifications has agreement. outer is design use composite/compounding polyolefin and modified polystyrene (PS) more blow molding film production 线. rear 者事实 upper is full equipment, this is due to polyolefin usually can polystyrene (PS) 层. blow molding polystyrene (PS) film can obtain very high orientation property - 甚至 high 于流延 mono toward tensile polystyrene (PS) (OPS) film. in certain application in this can can is advantages, is shrinkage rate high, it for hot molding machine can can formed is conditions.

       典 type blow molding polystyrene (PS) film impact strong/high degree
from to "不太差", Atofina石油 chemical company (以 front Fina油 and chemical company) elastomer business 经理Ken Cherry this 样指出. is, upper has polystyrene (PS) blow molding film in certain types degree upper or use high impact resistance polystyrene (PS) (HIPS) or use types similar styrene - butadiene copolymer (SBC)进行 modified 处理, 如Chevron/Phillips company K- resin, or Atofina company Finaclear. add upper 5%至30% SBC, polystyrene (PS) blow molding film tough degree can upper rise to "不太差" this tough property type 别, add high impact resistance polystyrene (PS) relatively 差. 取决于 mixed SBC type type and amount, blow molding polystyrene (PS) film hardness can from rigid property to elastic property scope/range inner 变化. use modified blow molding film SBCs generally is high styrene type product types, ratio/proportion large is 75% styrene and 25% butadiene. it is is film design.

        未蜂拥而至冲 toward blow molding polystyrene (PS) film field/area
兴趣 positive in upper rise although has new 者蜂拥而至冲 toward blow molding polystyrene (PS) film field/area 情景, for it 兴趣肯定 in increase large. machine 供货商说, in year 里, 他们都第 one-time by use polystyrene (PS) blow molding film experiment/testing. certain film processing positive in about/regarding blow molding polystyrene (PS) film field/area issues, especially is that through combined to this field/area expert company. 例如, in 俄亥俄州哥伦布市 plastics 供货商 manufacturing mono toward tensile polystyrene (PS) film, 并经销道 company blow molding polystyrene (PS) film already has more year. in, plastics 供货商 positive in 考虑自行 production blow molding polystyrene (PS) film. technology will 自Sidaplax company, this is ratio polystyrene (PS) film processing 厂商, is plastics 供货商 in 80 year in 期购买. Sidaplax company main/primary from 事流延 film manufacturing, production blow molding polystyrene (PS) film, used for type packaging label. plastics 供货商 positive in 哥伦布市 一家 new factory in use technology. and meanwhile, Avpex company, in method 尼亚州Hazleton Kama company positive in 考虑转 let it in obtain blow molding polystyrene (PS) film technology to it in UK new factory. Kama company in Europe production film, tube/pipe it in outer 经销Avpex company blow molding polystyrene (PS) film. modified polystyrene (PS) in mono and more blow molding film 方面找 to combined market. in 7～8 year 间出现 most large market is new food packaging use gas film. this film used as gas packaging (MAP)材 material 而闻名. polystyrene (PS) is it 沙拉沙拉 响声 to belt/tape new 鲜感觉 联想而风行一时. MAP application in 5 year left right time 里几乎 year year 翻番, 总部设 in inner 华达州Sparks world most large MAP film production 商Barrier Films company president/CEO Bill Wright如此说. food packaging materials requirements gas property water 平取决于 use SBC modifier amount, this is is it gas rate relatively pure polystyrene (PS) high. in packaging inner formed water can use 20%～30% SBC, 以允许 oxygen 自由进入, oxidation carbon 自由排出. relatively less product use 5%～10% SBC, that is is to improvement.

       Barrier Films company year consumption ultra- 1万磅 SBC modified polystyrene (PS)
used for production types product is Aluphane 7层MAP film in 2层. polystyrene (PS) /SBC构 formed film weight large 约30%. in 1992 year 开始商业化时, this type of film " in orientation polypropylene (PP) non tough, non has 效, "Wright说. Barrier Films company use DK-11 product grade K- resin and its it SBCs. color add in in polyolefin in, is EVA retardant 透层, make color, anti material from film to food in.

      very can can has more processing positive in blow molding MAP film, 包括SBC modified polystyrene (PS) film. it 们包括 in that Amko plastics company and in 纽约州罗切斯特市 原先 Cyprus Bags company, rear in is belongs to Cryovac/Sealed Air company mono 位. although large more 数包含 polystyrene (PS) MAP is production, is 伊利诺斯州Oswego already has 4 year history EPL soft packaging materials company (原先 Crystal Specialties company) blow molding mono polystyrene (PS) /SBC film, used for new product packaging. it more 层MAP film that 样, tool has waste material can heavy new use long 处. blow molding polystyrene (PS) film in food packaging 方面找 to its it applications. 例如, Switzerland Rorschach Permapack company 3 year front development 2 and 3层 polystyrene (PS) film, packaging use. Permapack company manufacturing hard film use hot molding processing, used for type pallet. product 之一由EVA(3μm), high SBC modified polystyrene (PS) (10μm)组 formed. types relatively thick (16μm) Permapack film, it use molding is 整 鸡 and belt/tape pallet, in SBC/ polystyrene (PS) 芯层 两侧各 has 3μm EVA层. substitute/replace 赛珞玢 blow molding polystyrene (PS) film its it market and film is same - 信封窗口, water hard packaging 纸, label and its it 赛珞玢代 use product, 此时, polystyrene (PS) 死褶效应, 沙拉沙拉响 and its it similar features is add advantages. 例如, very thin polystyrene (PS) film (4 mil) can lamination to upper made formed 贺卡, can in usually processing equipment upper processing. in this application in, hard packaging most strong/high growth 势头. its it 特殊赛珞玢代 use product market is used for food and transparent color color packaging, and used for lamination to can hot molding sheet/slice upper has gloss can printing film, procurement show/display. in Europe most new application 包括集邮 thin transparent 页, 保护文 parts sleeve/set bag, and and packaging sheet/slice 材. Dow more semi is 第一家 use blow molding polystyrene (PS) film substitute/replace 赛珞玢 processing 厂商. in 1960 year 代, Dow in as has " upper " film mono film equipment upper production blow molding polystyrene (PS) film. company in 俄亥俄州Hebron in 保密状况 lower 静悄悄 守 it Trycite film processing methods. in, Dow already has strip/profile production mono and more polystyrene (PS) film production 线. relatively 老 一 strip/profile is very small. rear strip/profile relatively large. most large production can production wide degree 达160 in(2.54 cm) product, ratio is 6:1. company is it film production types grade general purpose polystyrene (PS) resin. this film large more using/adopting high impact resistance polystyrene (PS) modified resin. in 1980 year, Dow in France Drusenheim兴建 第二 blow molding polystyrene (PS) factory, 而Sidaplax in ratio Gent-Bruge开始 blow molding polystyrene (PS) film. Italy Bari Europlast company in 1995 year blow molding mono polystyrene (PS), used for production 信封窗口 and label. it 4 strip/profile production is in company internal manufacturing. types low water foaming processing by used for blow molding polystyrene (PS) film, this 由Owens-Illinois company in it 肯塔基州 Bardsville factory 进行. foaming film water film methods production, used for soft material label. foaming has 利于饮 material bottle 子 保 cold.

        挑战 processing process large more equipment 供货商 in blow molding polystyrene (PS) film
方面 experience has 限. 马萨诸塞州Hingham Addex company sales strip/profile blow molding polystyrene (PS) film production 线, it is is 顾客 特殊 specifications requirements manufacturing. Germany Windmoeller & Hoelscher company in year semi front (1999 year)首次进行客户 experiment/testing. it very 惊奇 发现 polystyrene (PS) can in 未改进 blow molding film equipment upper production. Battenfeld Gloucester company in year to about/regarding blow molding polystyrene (PS) film 问讯, 但尚未 is 客户建造 equipment or experiment/testing. machine company president/CEO 指出, " about/regarding polystyrene (PS) blow molding parts is comparison difficult ", company 曾秘密 agreement supply polystyrene (PS) blow molding film and ring, from 未建造 整 strip/profile polystyrene (PS) production 线. experiment/testing blow molding polystyrene (PS) film resin company and 供货商们警告说, comparison polyolefin film, it must in slow more and fine more conditions lower 运转. "每一台 film extrusion molding machine 都希望尽 its can fast speed 运转, "Atofina company Cherry说. "但 for/regarding blow molding polystyrene (PS) film 而言, heat stabilized property is important. can let it hot, 否则会 make film 泡颤动 and film thick degree 不均". polystyrene (PS) blow molding processing temperature degree is very narrow, 消息 源说. also has, polystyrene (PS) film ratio polyolefin film cooling fast more, therefore its film has 10～12 ft(0.3m) high, has versus for high 泡颈. in machine toward (MD) and toward (TD)两 direction ratio is 6:1, tensile ratio is 36:1. polystyrene (PS) film polyethylene (PE) film use 滤网叠 and sheet/plate extrusion molding, used for polystyrene (PS) due to pellets relatively large relatively is fine 密. pellets in polyethylene (PE) film in can can is make product good 看, in polystyrene (PS) blow molding in it 们会毁掉一 film 泡. polystyrene (PS) film easy by 刮伤, 且边缘 has crazing toward, therefore and has step/link need is small 心, processing this 样说. 辊筒必 must can 自由转动并 use 橡胶包覆, production viscous property film 时 辊筒 that 样. in large more 数情况 lower, processing in 折叠时裁 flash. understanding use modifier due to polystyrene (PS) modifier for polystyrene (PS) film property can is important, therefore 任何关注 this field/area 人都必 must add modifier can obtain benefits. although high impact resistance polystyrene (PS) in improves polystyrene (PS) film property can has has 限 帮助, is, certain relatively new grade can provide relatively more benefits. 例如, Dow Styron A-Tech high impact resistance polystyrene (PS), in year front production, is 借助组 combined types different butadiene 橡胶而达 to di property, more 进一步改进 gloss and impact property can. Kraton polymer company launch types and other SBC product grade (D 1401P), is company 第一 供 packaging materials use Kraton product. Calsak company from Japan Denka company K- resin substitute/replace product. types 专门指 toward extrusion molding target/goal product grade is Clearen 730L. Atofina company plan will its in ratio 利时安特卫普 Finaclear SBC production 翻番, 2001 year to 9000万磅/ year. BASF company through increase in Germany production can force and in Mexico and ratio new factory expand 展Styrolux SBC full production, increase to 1 100 million 5千万磅/ year. new product will 包括一 new grade:Styrolux BX 6230. Dow development "Index" ethylene - styrene poly material (ESI) is types new substitute/replace product, substitute/replace SBC or high impact resistance polystyrene (PS), used for polystyrene (PS) impact property can. 报导说, it polystyrene (PS) impact property can need high polypropylene (PP) impact property can. 2000 year 初, company material products 部商业化 第一 blow molding film, is in general purpose polystyrene (PS) (GPPS) in use high 达50% ESI. this type of thick degree is 1.5 mil blow molding film by add hot lamination to 1 in thick Styrofoam(polystyrene (PS) foam)绝 hot sheet/plate upper. film has strong/high degree, can let construction in foam sheet/plate upper 行走. 当钉子 or U形钉 from sheet/plate upper 拔出时, film can anti sheet/plate loss 伤. "你永远不会 versus it is polystyrene (PS) ", film product development 经理Bill LaFollette说. it ratio polystyrene (PS) more tough, need bonding agent, but also sheet/plate material recycling very 方便.

        China can development polystyrene (PS) blow molding film polystyrene (PS)
is large general purpose plastics 之一, used for electronics electrical appliances, day use packaging products and other injection molding field/area, foaming packaging, foaming hot material and other can property polystyrene (PS) resin molding field/area, and used for box/case and other extrusion foaming sheet/slice field/area. in China polystyrene (PS) injection molding products polystyrene (PS) 总消费 amount 约60%, type foaming products 占约20, its it products 占约20%, film ratio/proportion very small, usually mono statistics. year, due to for polyvinyl chloride (PVC) generate ring issues 忧虑, in separation transparent sheet/slice application areas use polystyrene (PS) sheet/slice 材, tool 夹, hot molding packaging products and other. China 浙江宁波乐兴 packaging materials has company in upper 世纪90 year from Mitsubishi company 引进 首 strip/profile year production capacity to 8000 10,000 tons di toward tensile polystyrene (PS) film production 线, target/goal toward upper application areas, and 随 二次 processing hot molding equipment formed development, used for pallet packaging product already 经投入 market. rear also 陆续引进 more strip/profile di toward tensile polystyrene (PS) film production 线, another, in Shanghai, 华南 区也 has more strip/profile used for hot molding and other mono toward tensile polystyrene (PS) sheet/slice production 线, polystyrene (PS) film market in expand large, is, this production process basic upper is belongs to film method. another, inner has relatively more foaming tube/pipe film blow molding method production 线, used for box/case foaming polystyrene (PS) sheet/slice production, this production due to China use foaming polystyrene (PS) tool 面临闲置 or 转产. "ps blow molding film " one article in introduction use blow molding method production polystyrene (PS) film process tool has process simple, investment small advantages, currently from Raw Materials, modified, molding, equipment and application and other already 经趋于 formed 熟, in and other already obtain more application, is inner 尚未见 to blow molding polystyrene (PS) film production 线, through introduction, versus can to and related enterprise 一 启发, development this has development outlook/prospects product.
