Plastic bags need to be sealed when they are used. What are the methods of sealing?
First, heat seal:
1. Use a saw blade to heat it with fire, then roll the plastic film on it. It is absolutely practical and the effect is super good!
2. Take a stick and roll the bag to be sealed first, then heat it with a small fire. Don't take it too long, just like it all at once, so that the seal will not burn the bag.
Second, the electric iron seal: the electric iron is opened, at about the same temperature, put a piece of iron plate or hard things underneath, use a pressure on the back of the iron. But pay attention to the electric iron seal, pay attention to the following temperature and seal speed, not too slow, so that the plastic bag melts.
Third, the mechanical equipment for sealing: for a large number of plastic packaging bags to improve the sealing speed, you can use a sealing machine for sealing.
