PE拉伸膜/缠绕膜，又称LLDPE弹性膜/包装膜，是一种透明、富有弹性及强度且***无害的柔软聚乙烯塑料薄膜，符合国际环保卫生标准，可在不加热的情况下，进行纵横双向冷拉伸，依靠它本身自粘性包装各种产品，并可使货物长期保持张力而不至于松散，强度高、弹性拉力大、对任何形状的物品都能裹紧，裹成一个整体。拉伸包装比收缩包装节省材料,且不需要收缩包装机节省能源；具有良好的防松散、防雨、防尘、防盗等效果。有单面粘性的产品，减轻运输贮存中灰尘、沙粒，对膜表面污染。适用于托盘运输包装或货物栈板打包，均能防潮，防尘及减少人工、提***率，达到保护产品与降低成本的目的。尤其用于货物栈板打包运输作业，充分发挥胶膜的强韧性及自粘性，配合缠绕时层层张力的紧束作用，达到栈板打包***佳效果。还适应于展销会上参展产品（物品、机械）的周转；半成品的中转等种种场合适用。PEstretchedfilm/twistedfilm,isalsocalledLLDPEflexibilityfilm/packagingfilm,isakindofpolyethyleneplasticfilmwhichistransparent,flexibilityandintensity,aswellasnonpoisonousandhurtlesssoft,hasmetthestandardofinternationalenvironmentprotection,undertheconditionofno-heating,candocoldstretchingverticallyandhorizontally,andpackkindsofproductsdependingonitsself-stickiness,moreover,makesthepackedgoodskeeptenseandnotlooseinalongterm,andwrapsallgoodsastheintegertighteningwithitshighintensityandlargeflexibilityforce.Thestretchedpackagingmays***emorematerialsthantheshrinkingpackaging,andalsoismoreenergy-s***ingcomparedwiththeshrinkingpackaging;hastheeffectofnicerloose-proof,rain-proof,dust-proof,aswellastheft-proof,andsoon.Singleadhesiveproductscanreducethefilmsurfacepollutionwhichcausedbythedust,sandgrainduringthetransportation.Besuitedtothetraytransportationorgoodsstackboardpackaging,andarealldamp-proof,dust-prooftoreducethemanualwork,improvetheefficiency,andfinallyreachtheaimofprotectingtheproductsandloweringthecost.Especiallybesuitedtogoodsstackboardpackagingtransportationtaskforexertingthestrengthandtoughnessandself-stickinessofthegluefilm,cooperatingwithmanylayers’tensiontobindtenselywhenenlacing,andinordertogetthebesteffectofstackboardpackaging.Alsoissuitabletocycletheexhibitiveproducts(goodsandmachinery)intheexhibition;aswellasthesemi-manufacturedgoods,andsoon.)
