What kind of electric iron do you use? What special methods do you need?
The temperature of the electric iron is too high, and it is not easy to use.You put the bags in the hacksaw blades or something similar, over in alcohol lamp or candle flame on it. The length of time, according to the quality of the bag to grasp their own.You can also buy a sealing machine, one hundred or two hundred pieces, very good use.
Can not! Just use the flame of the candle
Electric iron can be used to seal ordinary plastic bags. But the efficiency is low.Ordinary plastic bags, as long as there is hot melt effect, you can use electric irons to heat seal. When operating, because of the higher surface temperature of the electric iron, it needs to be sealed with a layer of material that is more resistant to temperature than the plastic bag. For example, there are more than 300 degrees of Teflon film or mica slices, placed on the seal, and then use the electric iron on the seal painted straight line. According to the thickness of the material, you can slide back and forth. Until the seal is fused.
