说到塑料包装袋，我们很熟悉,我们需要在日常生活的许多方面使用塑料袋。它很受欢迎，但是在使用它的时候我们需要注意一些事项。下面济南复合塑料袋厂家为您讲解：

When it comes to plastic packaging bags, we are very familiar with them. We need to use plastic bags in many aspects of daily life. It is very popular, but we need to pay attention to some things when using it. Below, Jinan composite plastic bag manufacturer will explain to you:

一般来说，我们每天生产的塑料包装袋是没有气味的，但是如果有任何气味，肯定会有问题，这会对食品产生很大影响。

Generally speaking, the plastic packaging bags we produce every day are odorless, but if there is any odor, there will definitely be problems, which will have a significant impact on food safety.

一是残留溶剂：在配制过程中，食品塑料包装袋上的有机溶剂不会挥发。当“残留溶剂”含量低于标准值时，人们的嗅觉不会受到影响，也不会受到包装食品味道的影响。如果“残留溶剂”的含量超标，人们的嗅觉就会感觉到它的存在。当消费者打开高残留溶剂的食品袋时，他们会闻到与食品不同的“气味”。

One is residual solvents: During the preparation process, the organic solvents on food plastic packaging bags will not evaporate. When the content of "residual solvents" is lower than the standard value, people's sense of smell will not be affected, nor will it be affected by the taste of packaged food. If the content of "residual solvent" exceeds the standard, people's sense of smell will sense its existence. When consumers open food bags with high residual solvents, they will smell a different "smell" from the food.

二是树脂氧化气味：挤压复合是复合软包装材料的另一种复合工艺。在这个过程中，颗粒状塑料树脂需要在高温下熔化，通过模具涂覆在其他基材上，然后冷却并成型。如果温度过高，塑料树脂会被氧化分解，产生所谓的“树脂氧化气味”，可通过严格控制生产工艺条件加以。

The second is resin oxidation odor: extrusion composite is another composite process of composite soft packaging materials. In this process, granular plastic resin needs to be melted at high temperatures, coated on other substrates through molds, then cooled and formed. If the temperature is too high, the plastic resin will be oxidized and decomposed, producing the so-called "resin oxidation odor", which can be eliminated by strictly controlling the production process conditions.

为了延长保质期，方便运输到各地销售，市场上很合多食品都会选择包装袋进行包装，但并非所有的包装袋产品都适合包装。我们在包装前选择的材料也可以说直接关系到它们是否适包装食品。

In order to extend the shelf life and facilitate transportation to various regions for sales, many foods in the market choose packaging bags for packaging, but not all packaging bag products are suitable for packaging. The materials we choose before packaging can also directly affect whether they are suitable for packaging food.

塑料袋可以防潮。当我们用它们来储存物品时，它们可以起到防潮的作用。由于其透明的外观，我们可以从外部看到内部包含的项目。也方便大家区分,不需要一一打开。更多相关产品事项就来我们网站http://www.sztensun.com咨询吧！

Plastic bags can prevent moisture. When we use them to store items, they can play a moisture-proof role. Due to its transparent appearance, we can see the items contained internally from the outside. It is also convenient for everyone to distinguish and does not need to be opened one by one. For more product related matters, come to our website http://www.sztensun.com Consult!
