塑料袋是指用于包装各种材料的袋子，便于货物在生产和流通过程中的运输和储存。广泛应用于日常生活和工业生产中。大部分使用的塑料袋像普通垃圾一样被运到垃圾场，只有少量的塑料袋被回收利用。

Plastic bag refers to the bag used to pack various materials, which is convenient for the transportation and storage of goods in the process of production and circulation. It is widely used in daily life and industrial production. Most of the plastic bags used are transported to the dump like ordinary garbage, and only a small number of plastic bags are recycled.

在我们的日常生活中，我们几乎每天都接触到塑料袋。然而，塑料袋在使用前需要密封。密封可以使塑料袋更坚固、更美观。否则，即使塑料袋做得好，密封性差也会对产品的外观和使用产生一定的影响。让我们来看看如何密封塑料袋。

In our daily life, we are exposed to plastic bags almost every day. However, plastic bags need to be sealed before use. Sealing can make the plastic bag stronger and more beautiful. Otherwise, even if the plastic bag is well made, the poor sealing will have a certain impact on the appearance and use of the product. Let's see how to seal plastic bags.

一，热封：

1、 Heat seal:

用锯片加热，然后卷起塑料袋，非常实用。你也可以拿一根棍子，先把你想密封的袋子卷起来，然后用小火加热。不会太久。过一会儿，以免烧焦塑料袋。

It is very practical to heat with a saw blade and roll up the plastic bag. You can also take a stick, roll up the bag you want to seal, and then heat it over a low heat. It won't be long. After a while, so as not to scorch the plastic bag.

二，铁封：

2、 Iron seal:

打开熨斗。当温度相似时，在下面放一块铁板和其他硬物，压在电熨斗的背面。但在用电烙铁密封时，应注意以下温度和密封速度，以免塑料袋熔化过慢。

Turn on the iron. When the temperature is similar, put an iron plate and other hard objects under it and press it on the back of the electric iron. However, when sealing with electric soldering iron, pay attention to the following temperature and sealing speed to avoid slow melting of plastic bags.

三、密封机械设备：

3、 Sealing mechanical equipment:

为了提高大量塑料袋的密封速度，可以使用密封机密封。和一些普通的单层塑料袋一样，你可以用脚密封机密封。对于多层复合包装袋，如PET塑料袋，通常需要200度的高温才能密封。

In order to improve the sealing speed of a large number of plastic bags, a sealing machine can be used for sealing. Like some ordinary single-layer plastic bags, you can seal them with a foot sealer. For multi-layer composite packaging bags, such as PET plastic bags, it usually needs a high temperature of 200 degrees to seal.
