復合包裝袋其實在我們的生活中是很常見的產(chǎn)品,我們在用的時候須要知道的是其實它是兩種或兩種以上材料,在生產(chǎn)的是也都是經(jīng)過一次或多次干式復合工藝而組合在一起,從而構(gòu)成一定功能的包裝。這也還是它的制作過程。而且該產(chǎn)品它一般可分為基層、功能層和熱封層。復合包裝袋它的基層主要起美觀、印刷、阻濕等作用。而且它的功能層主要起阻隔、避光等作用。
In fact, the composite packaging bag is a very common product in our life. When we use it, we need to know that it is actually two or more kinds of materials. In production, it is also combined through one or more dry composite processes to form a package with a certain function. This is also its production process. Moreover, the product can generally be divided into base layer, functional layer and heat seal layer. The base layer of the composite packaging bag mainly plays the role of beauty, printing, moisture resistance, etc. Moreover, its functional layer is mainly used for blocking and avoiding light.
復合包裝袋主要用于服裝服飾、五金、電子、食品、醫(yī)藥、化妝品、飲料等產(chǎn)品的包裝。全球?qū)秃习b袋的需求一直保持著迅猛的發(fā)展態(tài)勢。復合包裝袋所能采用的基材種類繁多,常用的基材有:高密度、中密度、低密度聚乙烯薄膜(HDPE、MDPE.LDPE)、拉伸和未拉伸聚丙烯薄膜(BOPP、CPP)、聚酯薄膜(PET)、聚氯乙烯薄膜(PVC)、聚偏二氯乙烯薄膜(PVDC)、尼龍膜(NY)等。
Composite packaging bags are mainly used for packaging of clothing, hardware, electronics, food, medicine, cosmetics, beverages and other products. The global demand for composite packaging bags has maintained a rapid development trend. There are many kinds of substrates that can be used for composite packaging bags. The commonly used substrates are: high-density, medium density, low-density polyethylene films (HDPE, MDPE. LDPE), stretched and unstretched polypropylene films (BOPP, CPP), polyester films (PET), polyvinyl chloride films (PVC), polyvinylidene chloride films (PVDC), nylon films (NY), etc.
常見的復合包裝袋類型有:紙/塑復合、塑/塑復合、鋁/塑復合等。復合的基材層數(shù)可以是兩層、三層、四層、五層甚更多。按照復合塑料薄膜基材的種類和厚薄、組合的層數(shù)和順序,以及復合的方法,可以構(gòu)成許多種類的復合包裝袋。
Common types of composite packaging bags are: paper/plastic composite, plastic/plastic composite, aluminum/plastic composite, etc. The number of composite substrate layers can be two, three, four, five or more.
