How does the bag seal itself


The packaging bag refers to the bag used to pack various materials, so that the goods can be easily transported and stored in the production and circulation process. It is widely used in daily life and industrial production. The actual data shows that 80% of the used bags are transported to the landfill like ordinary garbage, and only 7% of the bags are recycled.

In our daily lives, we come into contact with packaging bags almost every day. However, the bag needs to be sealed before use. Do a good seal, you can make the bag stronger and more beautiful. Otherwise, even if the packaging bag is done well, the poor sealing will have a certain impact on the appearance and use of the product. Here's how to seal the bag.

Packing bag

First, heat seal:

Heat with a saw blade and roll up the bag. Very practical and effective. You can also take a stick and first roll up the bag you want to seal and heat it over low heat. It won't be long. It'll just be a minute before you burn the bag.

2. Iron seal:

Turn on the iron. When the temperature is about the same, put a hard object such as an iron plate underneath and press it on the back of the iron. However, when sealing with a soldering iron, pay attention to the following temperature and sealing speed, so as not to melt the bag too slowly.

Third, mechanical equipment for sealing:

In order to improve the sealing speed of a large number of packaging bags, you can use the sealing machine to seal. As with some ordinary single-layer packaging bags, you can use a foot sealing machine to seal. For multi-layer composite bags, such as PET bags, it usually requires a high temperature of 200 degrees to seal.

The above is actually the sealing method of the bag. The sealing of the bag is mainly temperature control. When the temperature is controlled, the seal is smooth and will not be damaged. Therefore, when sealing to test a suitable temperature, do not worry about mass production, to avoid waste.
