鉴别塑料包装袋好坏的原因

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过程中，选择哪种油墨也会产生很大的影响。有毒油墨接触食用油后容易褪色。因此，在购买带有印刷字样的塑料袋之前，可以使用食用油来测试印刷油墨是否足够。此外，有色塑料袋不能用作食品塑料袋。这种塑料袋含有芳烃，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，家庭规定制定制的塑料袋必须标明其自身的承载能力，但市场上仍有大量塑料袋产品没有标明承载能力。一个简单的测试方法是用塑料袋包装重量的产品，用塑料袋行走，看看袋子能持续多久。这个测试很麻烦，那么为什么买家要注意塑料袋的承载能力呢？这是因为承载能力差的塑料袋产品在使用过程中经常会破裂，这会增加客户使用的塑料袋数量，造成浪费。

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、要做焚烧实验。

3、 We need to conduct an incineration experiment.

塑料袋的原的原材料直接决定塑料袋的质量。由食品原料制成的袋子是废料，以及由废料和颜料制成的塑料袋生产成本低且有毒。点燃塑料袋，待塑料袋熄灭后，观察燃烧前后是否有黑烟、刺鼻气味和黑色物质。如果上述三种材料中有一种，实验中使用的塑料袋很可能是由废物制成的。

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.
