日常生活中(zhong)，纏繞膜也很常見。在各行(xing)各業的產品(pin)運(yun)(yun)送(song)中(zhong)都(dou)可以看到(dao)。尤(you)其是在主要產品(pin)的運(yun)(yun)送(song)中(zhong)，是運(yun)(yun)用率比(bi)較高的產品(pin)。那么纏繞膜在物(wu)流(liu)運(yun)(yun)送(song)過程中(zhong)有什(shen)么好處？

1、抗爆性好(hao)，不(bu)易損(sun)壞，柔韌性好(hao)。包裝貨(huo)(huo)品(pin)(pin)時(shi)，能起(qi)(qi)到很(hen)好(hao)的保(bao)護(hu)貨(huo)(huo)品(pin)(pin)的作用。用于(yu)物流運送，因其本(ben)身的抗拉(la)功能，可以緊緊包裹(guo)貨(huo)(huo)品(pin)(pin)。一些類似(si)于(yu)背包的拉(la)伸(shen)膜可以在(zai)包裹(guo)物品(pin)(pin)后(hou)直接將(jiang)物品(pin)(pin)從底部提起(qi)(qi)。

2、透(tou)光(guang)率高，透(tou)明度好。拉伸(shen)薄膜(mo)幾乎是透(tou)明的(de)。假(jia)如你用(yong)它(ta)來包(bao)裝(zhuang)貨品，它(ta)不僅可(ke)以(yi)完(wan)成包(bao)裝(zhuang)的(de)任(ren)務，還可(ke)以(yi)幫(bang)助你透(tou)過薄膜(mo)看清里邊的(de)東西。你可(ke)以(yi)用(yong)一(yi)(yi)(yi)石二(er)鳥(niao)。此外(wai)，拉伸(shen)膜(mo)還具有防塵、防潮的(de)功用(yong)。一(yi)(yi)(yi)同可(ke)以(yi)有效保護貨品。它(ta)是一(yi)(yi)(yi)種環保的(de)包(bao)裝(zhuang)材料。

3、本(ben)錢很低。拉(la)伸膜(mo)因其縮短力(li)強、抗(kang)性強、抗(kang)紫外(wai)線等特點(dian)，在物(wu)流運(yun)送中廣受(shou)歡迎。此外(wai)，纏(chan)繞膜(mo)的運(yun)用(yong)本(ben)錢較低，與其他容(rong)器(qi)和板條箱比較價格低廉，無需保護，不占用(yong)太多存(cun)儲空(kong)間(jian)。運(yun)用(yong)后還可(ke)以回收使用(yong)，超級環保。

纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)要(yao)求(qiu)的(de)(de)(de)(de)(de)粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)既要(yao)具有(you)良(liang)好(hao)的(de)(de)(de)(de)(de)剝(bo)離粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)也要(yao)具有(you)良(liang)好(hao)的(de)(de)(de)(de)(de)搭接(jie)粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)。剝(bo)離粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)越(yue)(yue)高(gao)(gao)(gao)，托盤(pan)越(yue)(yue)不易散包(bao)，且薄膜(mo)的(de)(de)(de)(de)(de)密封性(xing)(xing)(xing)(xing)(xing)(xing)(xing)越(yue)(yue)好(hao)；搭接(jie)粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)越(yue)(yue)高(gao)(gao)(gao)，薄膜(mo)越(yue)(yue)不易發生(sheng)縱向位移，因此(ci)要(yao)想獲得(de)牢固(gu)的(de)(de)(de)(de)(de)包(bao)裝，就(jiu)需要(yao)纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)的(de)(de)(de)(de)(de)剝(bo)離粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)和搭接(jie)粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)達(da)到均(jun)衡。1．分子(zi)量(liang)(liang)(liang)(liang)(liang)對(dui)纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)的(de)(de)(de)(de)(de)影(ying)響(xiang)分子(zi)量(liang)(liang)(liang)(liang)(liang)不同，纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)生(sheng)產廠(chang)家，粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)著性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)會(hui)隨(sui)之(zhi)不同，分子(zi)量(liang)(liang)(liang)(liang)(liang)高(gao)(gao)(gao)的(de)(de)(de)(de)(de)PIB使薄膜(mo)具有(you)更(geng)高(gao)(gao)(gao)的(de)(de)(de)(de)(de)剝(bo)離粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)著性(xing)(xing)(xing)(xing)(xing)(xing)(xing)，但(dan)(dan)是隨(sui)這PIB分子(zi)量(liang)(liang)(liang)(liang)(liang)的(de)(de)(de)(de)(de)增加(jia)(jia)，搭接(jie)粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)著力會(hui)衰減；而分子(zi)量(liang)(liang)(liang)(liang)(liang)太低的(de)(de)(de)(de)(de)話，由于其較易揮(hui)發會(hui)導致粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)保持時間過短。因此(ci)，選擇合適(shi)分子(zi)量(liang)(liang)(liang)(liang)(liang)的(de)(de)(de)(de)(de)PIB才能(neng)使得(de)纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)具有(you)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)。研究(jiu)表明(ming)，數均(jun)分子(zi)量(liang)(liang)(liang)(liang)(liang)在1300左(zuo)右的(de)(de)(de)(de)(de)PIB比較適(shi)用于增加(jia)(jia)纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)的(de)(de)(de)(de)(de)自粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)。2．添加(jia)(jia)量(liang)(liang)(liang)(liang)(liang)對(dui)纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)的(de)(de)(de)(de)(de)影(ying)響(xiang)纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)的(de)(de)(de)(de)(de)粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)與PIB加(jia)(jia)入(ru)量(liang)(liang)(liang)(liang)(liang)成(cheng)(cheng)正相關。但(dan)(dan)是，但(dan)(dan)PIB加(jia)(jia)入(ru)量(liang)(liang)(liang)(liang)(liang)超過3%之(zhi)后，纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)廠(chang)家，纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)自粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)的(de)(de)(de)(de)(de)提(ti)高(gao)(gao)(gao)變得(de)不明(ming)顯(xian)，若(ruo)繼(ji)續提(ti)高(gao)(gao)(gao)PIB的(de)(de)(de)(de)(de)加(jia)(jia)入(ru)量(liang)(liang)(liang)(liang)(liang)，PIB會(hui)在膜(mo)表面(mian)析出(chu)成(cheng)(cheng)塊，造成(cheng)(cheng)薄膜(mo)自粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)不均(jun)，甚(shen)至膜(mo)卷(juan)很難打開(kai)。為了保證纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)的(de)(de)(de)(de)(de)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)，纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)廠(chang)家批發，并綜合考(kao)慮原料(liao)成(cheng)(cheng)本問題，PIB的(de)(de)(de)(de)(de)添加(jia)(jia)量(liang)(liang)(liang)(liang)(liang)應(ying)控制在1~3%之(zhi)間。PIB有(you)一(yi)個滲出(chu)過程(cheng)，一(yi)般(ban)(ban)要(yao)三(san)天左(zuo)右的(de)(de)(de)(de)(de)時間纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)表面(mian)才能(neng)產生(sheng)足夠的(de)(de)(de)(de)(de)粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)。3．纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)儲存(cun)溫度(du)(du)(du)對(dui)粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)的(de)(de)(de)(de)(de)影(ying)響(xiang)PIB的(de)(de)(de)(de)(de)遷出(chu)速(su)度(du)(du)(du)與存(cun)放的(de)(de)(de)(de)(de)溫度(du)(du)(du)有(you)關，環境(jing)溫度(du)(du)(du)升(sheng)高(gao)(gao)(gao)，PIB的(de)(de)(de)(de)(de)遷出(chu)速(su)度(du)(du)(du)增加(jia)(jia)，粘(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)提(ti)高(gao)(gao)(gao)。因此(ci)，纏(chan)(chan)(chan)(chan)繞(rao)(rao)(rao)膜(mo)要(yao)達(da)到要(yao)求(qiu)的(de)(de)(de)(de)(de)粘(zhan)(zhan)(zhan)(zhan)(zhan)(zh
