Medium-density polyethylene

Okay kiddo, so you know about plastic, right? Well, there are different types of plastic and one of them is called medium-density polyethylene. You can call it MDPE for short.

MDPE is like the Goldilocks of plastics - not too hard, not too soft, but just right. It’s not as hard as some plastics, but not as soft as others either. It’s in the middle, which makes it a great material for all sorts of things.

One of the coolest things about MDPE is that it can be recycled (meaning we can use it again for something else) and it’s also very tough. That means it won’t break easily if you drop it or if someone steps on it. That’s why we often use MDPE for things like water pipes or even playground equipment.

But it’s not just for big things like pipes and playgrounds. You might have even seen MDPE in your house without realizing it. Some milk jugs and grocery bags are made from MDPE! It’s a pretty versatile plastic that can be used for all sorts of things.

So that’s a brief explanation of what medium-density polyethylene is. It’s a plastic that’s not too hard and not too soft, that’s great for recycling and is really strong.
