style="text-indent:25px">纏繞膜和拉伸膜的區(qū)別：纏繞膜和拉伸膜都用于包裹各類產(chǎn)品的銷售和運(yùn)輸，起到保護(hù)穩(wěn)固遮蓋的作用。兩個(gè)名稱指的同一個(gè)東西，纏繞膜的概念更廣一些，纏繞膜也叫拉伸膜，有的纏繞膜可拉伸，有的纏繞膜不可拉伸，或者說(shuō)拉伸率低，所以拉伸膜是屬于纏繞膜的范疇。纏繞膜又叫拉伸膜、熱收縮膜，國(guó)內(nèi)較早以PVC為基材，DOA為增塑劑兼起自粘作用生產(chǎn)PVC纏繞膜。但其成本高，PE拉伸膜先是以EVA為自粘材料，又有味道，后發(fā)展用PIBV、LDPE為自粘材料，基材現(xiàn)在以LLDPE為主，包括C4、C6、C8及金屬PEMPE。</p><p style="text-indent:25px">材料密度也影響著薄膜的性能。隨著密度的增加，取向度提高，平整度好，縱向伸長(zhǎng)率提高，屈服強(qiáng)度提高，但橫向撕裂強(qiáng)度、穿刺強(qiáng)度及透光率均下降，所以綜合各方面的性能，往往在非粘層添加適量的中密度線性聚乙烯(LMDPE)。添加LMDPE還可以降低非粘層的摩擦系數(shù)，避免包裝好的托盤(pán)與托盤(pán)粘連。冷卻輥溫度的影響。冷卻輥溫度升高，屈服強(qiáng)度提高，但其余性能下降，所以一般冷卻I輥的溫度控制在20℃～30℃為宜。流延線的張力影響薄膜的平整度及收卷松緊度，若使用PIB或其母料作為粘層，還影響PIB的遷出，降低薄膜較終的粘度。張力一般不大于10kg，太大了應(yīng)力殘存于膜卷內(nèi)，使伸長(zhǎng)率等性能下降，容易造成斷膜現(xiàn)象。拉伸膜的應(yīng)用形式拉伸膜的應(yīng)用領(lǐng)域很廣，主要是與托盤(pán)配合使用，對(duì)零散商品進(jìn)行整集包裝，代替小型集裝箱。由于它可降低批量貨物運(yùn)輸包裝成本30%以上，因而被普遍應(yīng)用于五金、礦產(chǎn)、化工、醫(yī)藥、食品、機(jī)械等多種產(chǎn)品的整集包裝上；在倉(cāng)庫(kù)貯存領(lǐng)域，國(guó)外也較多地利用拉伸纏繞膜托盤(pán)包裝進(jìn)行立體貯運(yùn)，以節(jié)省空間和占地。纏繞膜借助薄膜較強(qiáng)的纏繞力和回縮性，將產(chǎn)品緊湊地、固定地捆扎成一個(gè)單元。</p><div

style="text-indent:25px">纏繞膜物理機(jī)械性能的控制：高的透明度有利于貨物的識(shí)別；高的縱向伸長(zhǎng)率有利于預(yù)拉伸，且節(jié)省材料消耗；良好的穿刺性能及橫向撕裂強(qiáng)度允許薄膜在高拉伸倍率下遇到貨物尖銳的角或邊不斷裂；高的屈服點(diǎn)使包裝后的貨物更緊固。流延法生產(chǎn)的膜透明度高，這里不著重討論。隨著材料共聚單體C原子個(gè)數(shù)的增加，支鏈長(zhǎng)度增加，結(jié)晶度降低，生成的共聚物“纏繞或扭結(jié)”效應(yīng)增加，所以伸長(zhǎng)率提高，穿刺強(qiáng)度及撕裂強(qiáng)度也都提高。而MPE是高立構(gòu)規(guī)整聚合物，分子量分布很窄，可以準(zhǔn)確控制聚合物的物理性能，所以在性能上又有進(jìn)一步的提高；又由于MPE分子量分布窄，加工范圍也窄，加工條件難以控制，通常添加5%的LDPE，以降低熔體粘度，增加薄膜的平整度。 MPE的價(jià)格也高，為了降低成本，通常采用MPE與C4－LLDPE搭配使用，但并非所有的C4－LLDPE都能與之搭配，應(yīng)有所選擇。機(jī)用拉伸膜多采用C6、C8材料，容易加工，能滿足各種包裝要求。手工包裝由于拉伸倍率低，多采用C4材料。纏繞膜：預(yù)拉伸是由兩根輥完成的。蘇州塑料薄膜纏繞膜批發(fā)</p><p

style="text-indent:25px">纏繞膜特點(diǎn)：1.單元化：這是纏繞膜包裝的較大特性之一。借助薄膜較強(qiáng)的纏繞力和回縮性。2.初級(jí)保護(hù)性：初級(jí)保護(hù)性提供產(chǎn)品的表面保護(hù)，在產(chǎn)品周圍形成一個(gè)很輕的、保護(hù)性外表，從而達(dá)到防塵、防油、防潮、防水、防盜的目的。尤為重要的是纏繞膜包裝使包裝物品均勻受力，避免受力不均對(duì)物品造成損傷，這是傳統(tǒng)包裝方式（捆扎、打包、膠帶等包裝）無(wú)法做到的。3.壓縮固定性：借助纏繞膜拉伸后的回縮力將產(chǎn)品進(jìn)行纏繞包裝，形成一個(gè)緊湊的、不占空間的單元整體，使產(chǎn)品各托盤(pán)緊密地包裹在一起，可有效地防止運(yùn)輸過(guò)程中產(chǎn)品的相互錯(cuò)位與移動(dòng)，同時(shí)可調(diào)整的拉伸力可以使硬質(zhì)產(chǎn)品緊貼，使軟質(zhì)產(chǎn)品緊縮，尤其是在紡織業(yè)中有獨(dú)特的包裝效果。4.成本節(jié)約性：利用纏繞膜進(jìn)行產(chǎn)品包裝，可以有效降低使用成本，采用纏繞膜只有原本箱包裝的15%左右，熱收縮膜的35%左右，紙箱包裝的50%左右。同時(shí)可以降低工人勞動(dòng)強(qiáng)度，提高包裝效率以及包裝檔次。蘇州塑料薄膜纏繞膜批發(fā)</p><p
