濟(jì)南復(fù)合塑料袋:復(fù)合塑料包裝袋定制需要遵守的原則
在包裝工業(yè)發(fā)展的基礎(chǔ)上，物品的包裝也得到相應(yīng)的發(fā)展。從簡(jiǎn)單紙包裝，到單層塑料薄膜包裝，發(fā)展到復(fù)合材料的廣泛使用。復(fù)合膜能使包裝內(nèi)含物具有保濕、保香、美觀、保鮮、避光、防滲透、延長(zhǎng)貨架期等特點(diǎn)，因而得到迅猛發(fā)展。
On the basis of the development of packaging industry, the packaging of goods has also been developed accordingly. From simple paper packaging, to single-layer plastic film packaging, to the extensive use of composite materials. The composite film can make the contents of the package have the characteristics of moisturizing, fragrance preserving, beauty preserving, fresh-keeping, light avoiding, impermeability, and extending the shelf life, so it has developed rapidly.
復(fù)合塑料包裝袋比傳統(tǒng)包裝袋實(shí)用性要更好一些，防水性、耐熱性都要遠(yuǎn)遠(yuǎn)超過(guò)普通包裝袋。下面就讓我們來(lái)看看復(fù)合包裝袋的組成材料有什么吧。
Composite plastic packaging bags are more practical than traditional packaging bags, and their water resistance and heat resistance are far more than ordinary packaging bags. Now let's take a look at the constituent materials of composite packaging bags.
復(fù)合塑料包裝袋是由兩種或兩種以上塑料原材料，經(jīng)過(guò)一次或多次復(fù)合工藝而組合在一起，從而構(gòu)成具有特定功能的塑料復(fù)合袋。一般可分為基層、功能層和熱封層?；鶎又饕鹈烙^、印刷、阻濕等作用。如BOPP、BOPET、BOPA、MT、KOP、KPET等;功能層主要起阻隔、避光等作用，如VMPET、AL、EVOH、PVDC等;熱封層與包裝物品直接接觸，起適應(yīng)性、耐滲透性、良好的熱封性，以及透明性、開(kāi)口性等功能，如LDPE、LLDPE、MLLDPE、CPP、VMCPP、EVA、EAA、E-MAA、EMA、EBA等。
Composite plastic packaging bag is a plastic composite bag with specific functions, which is composed of two or more plastic raw materials through one or more composite processes. Generally, it can be divided into base course, functional layer and heat sealing layer. The base course mainly plays the role of aesthetics, printing, moisture resistance, etc. Such as BOPP, BOPET, BOPA, MT, Kop, kpet, etc; The function layer is mainly used to block and avoid light, such as VMPET, Al, EVOH, PVDC, etc; The heat sealing layer is in direct contact with the packaging, which has the functions of adaptability, permeability resistance, good heat sealing, transparency, openness and so on, such as LDPE, LLDPE, mLLDPE, CPP, VMCPP, EVA, EAA, e-maa, EMA, EBA, etc.
復(fù)合塑料包裝袋所牽涉的原材料種類(lèi)較多，性質(zhì)各異，哪些塑料材料可以結(jié)合或不能結(jié)合，用什么東西黏合等，問(wèn)題比較多而復(fù)雜，所以必須對(duì)塑膠袋原材料精心選擇，方能獲得理想的效果。選擇的原則如下：
There are many kinds of raw materials involved in composite plastic packaging bags, with different properties, which plastic materials can be combined or not, and what things are used to bond, etc. there are many and complex problems, so we must carefully select the raw materials of plastic bags in order to obtain the ideal effect. The recommended selection principles are as follows:
A、明確包裝對(duì)象和要求;
A. Specify the packaging object and requirements;
B、選用合適的塑料原材料和加工方法;
B. Select appropriate plastic raw materials and processing methods;
C、采用恰當(dāng)?shù)恼澈蟿┗驅(qū)雍显稀?/div>
C. Use appropriate adhesives or laminating materials.
