1. Use a saw blade to heat it with fire, and then roll the plastic film. It's absolutely practical and the effect is super good! The effect is the same as that of the sealing machine! But if you don't want to use this, you can just take a stick, roll up the bag to be sealed first, and then heat it with a small fire. It won't take too long. It's good all at once. In this way, if it's sealed firmly, it won't burn the bag.

Or there is a simpler way: bake the plastic bag soft with fire, then leave the flame and hold the opening with your hand. If you feel that these methods are not good, you can only use a professional sealing machine. That way, the sealing is very good-looking and firm.

2. Turn on the electric iron (it's common in this family). When the temperature is about the same, use the straight place behind (because both sides are arc lines, and the front is sharp, which is not easy to use). Put an iron plate or hard thing under it. Just press it behind the electric iron (the length of time can be controlled by yourself, maybe two seconds. It depends on the temperature, but it's best not to be too high, It's OK to have 100 degrees, otherwise it will dissolve if your hands and feet are slow.
