濟南塑料袋 高壓塑料袋和低壓塑料袋哪個好?

塑料袋高壓低壓哪個好?在進入主題之前跟大家科普一下什么高壓塑料袋?什么是低壓塑料袋?不知道的商家不妨花兩 分鐘看下,相信會對你有所幫助,知道的可以跳過。
Which is better for plastic bags with high pressure and low pressure? What kind of high-pressure plastic bags do you want to talk about before entering the topic? What is low pressure plastic bag? Businesses who don't know may as well take two minutes to have a look. I believe it will be helpful to you. You can skip what you know.
 
高壓塑料袋,高壓袋指的是用LDPE制作而成的塑料袋子,也就是塑料袋廠家口中所說的PE。PE塑料包裝材料制成的袋子的光 澤度較好,質(zhì)感較軟,用手輕晃,響聲很小。是上公認的接觸食品材料。是塑料袋印刷用量多、重要的材料。
 
High pressure plastic bag refers to the plastic bag made of LDPE, that is, PE in the mouth of the plastic bag factory. The bags made of PE plastic packaging materials have good gloss and soft texture. They shake gently with hands and make little noise. It is a recognized food contact material in the world. It is an important material with large amount of plastic bag printing.
 
低壓塑料袋,低壓袋指的是用HDPE制作而成的塑料袋子,也就是塑料袋廠家口中所說的PO。PO材料制成的塑料袋子的光澤度 較低,質(zhì)感略硬,用手輕晃,能聽到嘩嘩的響聲。這兩種材料(全新料)都無味。
 
Low pressure plastic bag refers to the plastic bag made of HDPE, which is the so-called Po in the mouth of the plastic bag factory. The plastic bag made of Po material has low gloss and slightly hard texture. When shaking with your hand, you can hear the noise. Both materials (all new materials) are tasteless.

那么高壓低壓塑料袋哪個好呢?
 
So which is better, high-pressure and low-pressure plastic bag?
 
小編已經(jīng)不知道和大家說過多少次了,塑料袋材料沒有誰好誰差之分,只有合適與不合適之分。比喻PE,PE是塑料袋印刷用 量多、重要的材料。我們平時逛街時,商家使用的一般都是用PE材質(zhì)制作也就是高壓。而我們平時使用得多的卻使用的材料 則是PO也就是低壓,為什么不用PE呢?
 
I don't know how many times I have told you that plastic bag materials are not good or bad, only suitable and inappropriate. Compared with PE, PE is an important material with large amount of plastic bag printing. When we usually go shopping, businesses usually use PE material, that is, high pressure. The material we usually use more is Po, that is, low pressure. Why not use PE?
 
那是因為PE無論是硬度和韌性都比不上PO,而背心袋不像塑料袋,裝的商品比較雜亂,對袋子的硬度和韌性都有很高的要求 ,這也就是為什么制作一般都用PO的原因。那為什么不用PO制作塑料袋呢?
 
That's because PE can't compare with Po in terms of hardness and toughness. Unlike plastic bags, vest bags contain messy goods and have high requirements for the hardness and toughness of bags. That's why Po is generally used in making. Then why not use Po to make plastic bags?
 
那是因為用PO制作的塑料袋,外觀會打皺,而需要塑料袋的客戶一般對塑料袋的外觀要求比較高,裝的商品也比較單一,這 也就是為什么不用韌性和硬度都比較好的PO的原因。
 
That's because plastic bags made with Po will wrinkle in appearance, while customers who need plastic bags generally have high requirements for the appearance of plastic bags and the goods loaded are relatively single, which is why Po with good toughness and hardness is not used.
