PE拉伸膜/纏繞膜，又稱LLDPE彈性膜/包裝膜，是一種透明、富有彈性及強(qiáng)度且無毒無害的柔軟聚乙烯塑料薄膜，符合國際環(huán)保衛(wèi)生標(biāo)準(zhǔn)，可在不加熱的情況下，進(jìn)行縱橫雙向冷拉伸，依靠它本身自粘性包裝各種產(chǎn)品，并可使貨物長期保持張力而不至于松散，強(qiáng)度高、彈性拉力大、對(duì)任何形狀的物品都能裹緊，裹成一個(gè)整體。拉伸包裝比收縮包裝節(jié)省材料,且不需要收縮包裝機(jī)節(jié)省能源；具有良好的防松散、防雨、防塵、防盜等效果。
有單面粘性的產(chǎn)品，減輕運(yùn)輸貯存中灰塵、沙粒，對(duì)膜表面污染。
適用于托盤運(yùn)輸包裝或貨物棧板打包，均能防潮，防塵及減少人工、提高效率，達(dá)到保護(hù)產(chǎn)品與降低成本的目的。尤其用于貨物棧板打包運(yùn)輸作業(yè)，充分發(fā)揮膠膜的強(qiáng)韌性及自粘性，配合纏繞時(shí)層層張力的緊束作用，達(dá)到棧板打包最佳效果。
還適應(yīng)于展銷會(huì)上參展產(chǎn)品（物品、機(jī)械）的周轉(zhuǎn)；半成品的中轉(zhuǎn)等種種場合適用。

PE stretched film/twisted film, is also called LLDPE flexibility film/packaging film, is a kind of polyethylene plastic film which is transparent, flexibility and intensity, as well as nonpoisonous and hurtless soft, has met the standard of international environment protection, under the condition of no-heating, can do cold stretching vertically and horizontally, and pack kinds of products depending on its self-stickiness, moreover, makes the packed goods keep tense and not loose in a long term, and wraps all goods as the integer tightening with its high intensity and large flexibility force. The stretched packaging may save more materials than the shrinking packaging, and also is more energy-saving compared with the shrinking packaging; has the effect of nicer loose-proof, rain-proof, dust-proof, as well as theft-proof, and so on.
Single adhesive products can reduce the film surface pollution which caused by the dust, sand grain during the transportation.
Be suited to the tray transportation or goods stack board packaging, and are all damp-proof, dust-proof to reduce the manual work, improve the efficiency, and finally reach the aim of protecting the products and lowering the cost. Especially be suited to goods stack board packaging transportation task for exerting the strength and toughness and self-stickiness of the glue film, cooperating with many layers’ tension to bind tensely when enlacing, and in order to get the best effect of stack board packaging. Also is suitable to cycle the exhibitive products ( goods and machinery )in the exhibition; as well as the semi-manufactured goods, and so on.
