濟(jì)南塑料袋要如何進(jìn)行選擇

來(lái)源:http://wujikeji.com/ 日期:2022-08-22

人們平時(shí)都會(huì)使用塑料袋來(lái)盛裝物品,因?yàn)槭褂盟芰习b袋來(lái)盛裝物品很便捷,但是隨著人們意識(shí)的增強(qiáng),人們已經(jīng)開(kāi)始對(duì)塑料包裝袋的應(yīng)用進(jìn)行了限制規(guī)定,這樣可以降低塑料包裝袋對(duì)環(huán)境的危害,很多廠家也開(kāi)始制作生產(chǎn)可以降解的塑料包裝袋,所以人們?cè)谑褂盟芰习b袋的過(guò)程中,應(yīng)該注意選用符合標(biāo)準(zhǔn)的包裝袋來(lái)盛裝物品,這樣可以降低對(duì)環(huán)境的影響。
People usually use plastic bags to contain goods, because it is convenient to use plastic bags to contain goods. However, with the enhancement of people's environmental awareness, people have begun to restrict the application of plastic bags, which can reduce the harm of plastic bags to the environment. Many manufacturers have also started to produce degradable plastic bags. Therefore, in the process of using plastic bags, Attention should be paid to the selection of packaging bags that meet environmental protection standards to contain goods, so as to reduce the impact on the environment.
在購(gòu)買使用塑料袋期間,還可以看到一種由聚氯乙烯制成的包裝袋,很多人也許對(duì)于聚氯乙烯的了解不是很多,所以認(rèn)為這種原材料本身是存在毒害作用的,其實(shí)聚氯乙烯對(duì)人體沒(méi)有任何危害,但是使用這種材料制成包裝袋的時(shí)候會(huì)加入很多化學(xué)試劑,所以制成的包裝袋對(duì)人體是有副作用的,因此這種包裝袋不可以直接用來(lái)盛裝食品,可以盛裝垃圾等物品。
During the purchase and use of plastic bags, you can also see a packaging bag made of polyvinyl chloride. Many people may not know much about polyvinyl chloride, so they think that this raw material itself has toxic effects. In fact, polyvinyl chloride has no harm to human body. However, when using this material to make packaging bags, many chemical reagents will be added, so the packaging bags made have side effects on human body, Therefore, this kind of packaging bag can not be directly used to contain food, but can contain garbage and other items.
另外在使用塑料袋時(shí),如何正確辨別也是非常重要的因素,平時(shí)用來(lái)盛裝食品的塑料包裝袋大多數(shù)都是由聚乙烯膜材料制成的,這種原材料在使用的過(guò)程中沒(méi)有任何毒害性作用,所以如果是用塑料包裝袋來(lái)盛裝食品的話,應(yīng)該選用這種包裝。
In addition, when using plastic bags, how to correctly identify is also a very important factor. Most of the plastic bags used to contain food are made of polyethylene film material. This raw material has no toxic effect in the process of use. Therefore, if plastic bags are used to contain food, this kind of packaging should be selected.
平時(shí)在使用塑料袋時(shí),非常簡(jiǎn)單的方式就是通過(guò)氣味來(lái)進(jìn)行分辨,如果發(fā)現(xiàn)塑料包裝袋有刺鼻的氣味,那么在使用這種包裝袋時(shí)就要比較謹(jǐn)慎。
Usually, when using plastic bags, a very simple way is to distinguish by smell. If you find that the plastic bags have pungent smell, you should be more careful when using such bags.
