塑料袋是指用于包裝各種材料的袋子，便于貨物在生產和流通過程中的運輸和儲存。廣泛應用于日常生活和工業(yè)生產中。大部分使用的塑料袋像普通垃圾一樣被運到垃圾場，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.

在我們的日常生活中，我們幾乎每天都接觸到塑料袋。然而，塑料袋在使用前需要密封。密封可以使塑料袋更堅固、更美觀。否則，即使塑料袋做得好，密封性差也會對產品的外觀和使用產生一定的影響。讓我們來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，熱封：

1、 Heat seal:

用鋸片加熱，然后卷起塑料袋，非常實用。你也可以拿一根棍子，先把你想密封的袋子卷起來，然后用小火加熱。不會太久。過一會兒，以免燒焦塑料袋。

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，鐵封：

2、 Iron seal:

打開熨斗。當溫度相似時，在下面放一塊鐵板和其他硬物，壓在電熨斗的背面。但在用電烙鐵密封時，應注意以下溫度和密封速度，以免塑料袋熔化過慢。

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、密封機械設備：

3、 Sealing mechanical equipment:

為了提高大量塑料袋的密封速度，可以使用密封機密封。和一些普通的單層塑料袋一樣，你可以用腳密封機密封。對于多層復合包裝袋，如PET塑料袋，通常需要200度的高溫才能密封。

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.
