Shanghai Daoqin Plastics Co., Ltd.

         film production 商普遍 issues: plastics film between viscous 连;迁移 property slip masterbatch effect/influence film hot printing property can.

         causes: main/primary is film combined rear film formed true combined 状态, easy separation 开.

         solution methods: 添 add 开口爽 slip masterbatch; for/regarding has hot and printing requirements film, can selection non low friction coefficient resistant viscous masterbatch.

        开口爽 slip masterbatch function - small sheet/plate, large can amount!

        1, film and 收卷都变 容 easy

        2, film use process in easy 开口

        开口爽 slip masterbatch:

        开口 masterbatch 由载体 resin, resistant viscous agent or slip agent and various additives formed, its resistant viscous agent, slip agent main/primary has:

        油 acid amine: features is small separation structure, fast, lubricated property relatively good, price 便宜, has Domestic has 10几元/kg, is acid amine non easy yellowing, high temperature resistance, easy film surface, short, heavy effect/influence product quality, meanwhile more effect/influence printing and hot property, this is very more low quality slip masterbatch raw materials selection;

        芥 acid amine: relatively acid amine carbon need more, molecular weight large, versus for stability, lubricated good, easy yellowing, high temperature resistance, long, long 期会发生部 separation yellowing, is price 贵;

         micron SiO2: SiO2 selection non important, must selection add amount less resistant viscous good, and 粒径适 combined, 折射系数 and film resin 接近, in above upper, also need to SiO2必 must easy dispersion, dispersion SiO2会团 poly effect/influence film table/sheet and optical property can and printing property can.

        当熟悉组 formed 开口爽 slip masterbatch slip agent types type and 开口爽 slip masterbatch function rear, for/regarding film production most important issues is:

         how to selection combined 适 开口爽 slip masterbatch?

        本文 will from below/following 3 方面进行阐述:

        1, meet/satisfy film property can demand 开口爽 slip masterbatch selection

        2, Common packaging film product 开口爽 slip masterbatch selection

        3, film application 开口爽 slip masterbatch Common issues and solutions

         through 三 方面 阐述开口爽 slip masterbatch (small sheet/plate, large can amount!) selection, let positive in reading 此文 您 has in-depth understanding.

        一, selection 开口爽 slip masterbatch 总原则

        开口爽 slip masterbatch selection remove to its excellent resistant viscous outer, main/primary also has below/following 几点:

        1, optical property can: is obtain most good transparent degree and most low degree, 开口爽 slip agent must selection rate and resin versus (1.49), distribution narrow, 粒径适 combined, add amount less can to 需 开口效果.

        2, dispersion property: anti-blocking agent very key/critical, 粒径越 small good dispersion, large also effect/influence film table/sheet property and optical property can, anti-blocking agent generally selection 2-10 micron, need masterbatch production has high dispersion di screw machine and masterbatch dispersion production experience.

        3, hot and printing property can: film in hot and printing front generally need electrical or 者火焰处理 increase film surface force and surface can, 但不适 amount slip agent 会迁移 to film surface effect/influence film hot and printing property can, formed film between strong/high degree low and ink viscous force strong/high, for this requirements film can selection friction coefficient low, non 迁移 开口爽 slip masterbatch.

        4, metal film anti property can: is anti machine resistant viscous agent film from low water 汽, oxygen gas retardant property can, resistant viscous agent can selection and soft/flexible pellets, can ensure film tool has more good retardant property can.

        5, for machine anti abrasion loss property can: has machine resistant viscous type hardness large, for machine abrasion loss non large, this is film production need heavy 视 方.

        6, 滤网堵塞 issues: if film 厂家遇 to pressure upper rise very high or pressure 差突然 rise high 情况, can can need more 换开口爽 slip masterbatch

        7, price: cost is in meet/satisfy above basic property can rear, need focus/key point factors.

        二, Common film 开口爽 slip masterbatch selection

        （一）镀 aluminum film

        "无穷"牌鸡爪以 and very more food packaging is aluminum film, it tool has excellent oxygen gas retardant property and anti oxidation, and gas dispersion property can, also tool has anti outer light, anti 止维生素流失 property can, in non high true conditions lower, aluminum in temperature degree to 1500 degree 时会汽化, rear in already film surface upper 一层极 thin aluminum film, is ensure metal and film bonding property, film must tool has high degree lubricating wet force, aluminum film 开口爽 slip masterbatch selection requirements:

        1, masterbatch 载体尽 amount selection lubricating wet force high

        2, property 开口爽 slip masterbatch must use

        3, film resistant viscous and slip 效果必 must through add resistant viscous masterbatch to

        4, resistant viscous agent pellets large small film table/sheet thick degree 而定

        5, resistant viscous agent 形状必 must is 圆形且 soft/flexible, this 样才不会刺穿镀 aluminum 层

        （二）香烟 packaging film

        烟 film material is BOPP di toward tensile polypropylene (PP), is multiple polypropylene (PP) function property material 进行共挤, di toward tensile molding. friction coefficient is amount degree BOPP烟 film sliding features indicators, film friction coefficient must different, must formed film inner and outer 面 差别式 sliding features, 贴近烟包 box/case 纸一面 and inner friction coefficient control relatively high, film outer must control very low. 开口爽 slip masterbatch selection requirements:

        1, 开口爽 slip masterbatch need in high temperature lower maintain low friction coefficient

        2, 开口爽 slip masterbatch tool has non property

        3, 开口爽 slip tool has non low friction coefficient features

        4, effect/influence film gloss degree and transparent degree

        5, effect/influence film degree and shrinkage rate

        （三）POF hot shrinkage film

        POF full more 层共挤 polyolefin hot shrinkage film, it is will property low density polyethylene (PE) as is in 间层(LLDPE), polypropylene (PP) (PP) as is inner, outer 层, through extrusion machine extrusion, again 经模头 molding, film 泡吹胀 and other process processing formed, it is types world upper use most 广泛, development speed new type environmental protection shrinkage film.

        POF upper 开口爽 slip masterbatch selection requirements:

        1, tool has excellent long 效 开口爽 slip 效果

        2, good gloss degree

        3, excellent transparent degree, low degree

        4, has film resistant and resistant property

        5, can film 收卷时跑偏

        6, has film shrinkage

        7, effect/influence film printing

        8, combined FDA food certification

        9, price

        （四） water sleeve/set bag film

         water sleeve/set bag is in recent years 果农越 越流行 做 method, it separation is PE film bag, bag, film +纸 bag, to 苹果, 葡萄, and other sleeve/set upper bag film. PE water film bag features is non thin, thick degree 约仅0.05 filament, large large reduce cost, film thin, easy viscous in 一起, easy 开口, therefore water bag film 开口爽 slip masterbatch selection requirements:

        1, 开口爽 slip masterbatch slip agent content need high, has masterbatch add 都遵循 film thin, add amount more 原则

        2, 开口爽 slip masterbatch can has machine filler, has add, in day 照雨淋自然 ring lower, film easy 烂

        3, film thin, electrical generate easy 吸附空 gas in 灰尘, selection slip meanwhile anti-static 效果

        4, combined FDA food certification

        （五） generally packaging film

        平常 见 to powder bag, film, fast bag, food packaging bag and other and other, this Common packaging film mono 层, or 者五层共挤, again blow molding, 流涎, tensile and other process molding, rear through separation 切, electrical 晕, hot 封, printing, formed is 我们现实生 active Common packaging bag. this film in obtain friction coefficient in 0.2 below/following meanwhile, need to 开口爽 slip masterbatch 会不会 effect/influence to film hot and printing property can.

        三, film application 开口爽 slip masterbatch Common issues and solutions

         film production use anti-blocking material issues analysis and solution methods:
