鑒別塑料包裝袋好壞的原因

一、看塑料袋油墨是否有毒。

1、 Check if the ink on the plastic bag is toxic.

在定制塑料袋的印刷過程中，選擇哪種油墨也會(huì)產(chǎn)生很大的影響。有毒油墨接觸食用油后容易褪色。因此，在購(gòu)買帶有印刷字樣的塑料袋之前，可以使用食用油來測(cè)試印刷油墨是否足夠。此外，有色塑料袋不能用作食品塑料袋。這種塑料袋含有芳烴，具有致癌作用。

The choice of ink also has a significant impact on the printing process of customized plastic bags. Toxic ink is prone to fading when in contact with edible oil. Therefore, before purchasing plastic bags with printed words, edible oil can be used to test whether the printing ink is sufficient. In addition, colored plastic bags cannot be used as food plastic bags. This plastic bag contains aromatic hydrocarbons and has carcinogenic effects.

二、看塑料袋的承重能力。

2、 Check the load-bearing capacity of plastic bags.

目前，家庭規(guī)定制定制的塑料袋必須標(biāo)明其自身的承載能力，但市場(chǎng)上仍有大量塑料袋產(chǎn)品沒有標(biāo)明承載能力。一個(gè)簡(jiǎn)單的測(cè)試方法是用塑料袋包裝重量的產(chǎn)品，用塑料袋行走，看看袋子能持續(xù)多久。這個(gè)測(cè)試很麻煩，那么為什么買家要注意塑料袋的承載能力呢？這是因?yàn)槌休d能力差的塑料袋產(chǎn)品在使用過程中經(jīng)常會(huì)破裂，這會(huì)增加客戶使用的塑料袋數(shù)量，造成浪費(fèi)。

At present, custom plastic bags made by families must indicate their own load-bearing capacity, but there are still a large number of plastic bag products on the market that do not indicate their load-bearing capacity. A simple testing method is to package the weight of the product in plastic bags, walk in the plastic bags, and see how long the bags can last. This test is very complicated, so why should buyers pay attention to the load-bearing capacity of plastic bags? This is because plastic bag products with poor load-bearing capacity often break during use, which increases the number of plastic bags used by customers and causes waste.

三、要做焚燒實(shí)驗(yàn)。

3、 We need to conduct an incineration experiment.

塑料袋的原的原材料直接決定塑料袋的質(zhì)量。由食品原料制成的袋子是廢料，以及由廢料和顏料制成的塑料袋生產(chǎn)成本低且有毒。點(diǎn)燃塑料袋，待塑料袋熄滅后，觀察燃燒前后是否有黑煙、刺鼻氣味和黑色物質(zhì)。如果上述三種材料中有一種，實(shí)驗(yàn)中使用的塑料袋很可能是由廢物制成的。

The raw materials of plastic bags directly determine their quality. Bags made from food ingredients are waste, and plastic bags made from waste and pigments have low production costs and are toxic. Ignite the plastic bag and observe for black smoke, pungent odor, and black substances before and after the bag goes out. If one of the three materials mentioned above is used, the plastic bag used in the experiment is likely to be made from waste.
