Plastic packaging bags need to be sealed when they are in use. So, what are the sealing methods? Today, the manager of Zeyi Packaging will give you a brief introduction.
One, heat sealing:
1. Use a saw blade to heat it with fire, and then roll the plastic film. It is absolutely practical and the effect is super good!
2. Take a stick, roll up the bag to be sealed, and then heat it with a small fire. Don’t take too long, it will be done all at once, so that it is sealed tightly and the bag will not be burned.
2. Electric iron seal: Turn on the electric iron. When the temperature is about the same, place an iron plate or hard object underneath, and press the back of the electric iron. But pay attention to the following temperature and sealing speed when sealing with an electric iron, and don’t cause the plastic bag to melt too slowly.
Three, mechanical equipment for sealing: For a large number of plastic packaging bags, if you want to increase the sealing speed, you can use a sealing machine for sealing.
