Heat sealer

Alright kiddo, have you ever seen a plastic bag with a tiny little line on the top? That line is actually made by something called a heat sealer!

A heat sealer is a machine that makes those little lines on plastic bags by using heat to melt the plastic together. It has two flat bars that get really hot and they lay on top of the plastic bag. When they touch each other, they press the plastic together and melt it just enough to make a little line.

That little line is really important because it keeps the bag closed and makes sure nothing falls out or gets inside the bag. The heat sealer can also make different kinds of lines, like wavy or straight, depending on what the person using it needs.

Overall, a heat sealer is a really helpful machine that helps create all sorts of products like plastic bags, packaging and even some types of food!
