Is your brain feeling stuffed from yesterday? Well if not, today we are going to talk about plastics recycling number 2. There are two plastics that are accepted under this recycling number. They are HDPE and MDPE. Before you ask, LDPE falls under recycling number 4, so we will get to it later this week! These acronyms stand for High-density polyethylene and Medium-density polyethylene. Now what is the difference?
The difference between HDPE and MDPE is that HDPE is slightly stronger and heavier that MDPE. Both of these plastics are made in a similar manner by combining petroleum with a catalyst like chromium/silica catalysts, Ziegler-Natta catalysts or metallocene catalysts.
The production manner of these plastics means that these are plastics with a good resistance to dropping, rapid temperature changes as well as resistance to some solvents. This makes these containers ideal for milk jugs, cleaner bottles, yogurt containers, shampoo & conditioner bottles, as well many more uses including construction and medical uses.
So… where can we find HDPE & MDPE being used?
HDPE & MDPE are used most commonly used in bottles and tubs, as well as cereal bags! HDPE & MDPE are a common container material in both the food and cosmetics industries because HDPE & MDPE are squeezable and have low costs in comparison to PET. This means that you don’t have to have higher products costs just to pay for the containers!
HDPE & MDPE are accepted at many recycling centers and are often recycled into laundry detergent bottles, oil bottles, recycling containers, plastic lumber, doghouses, picnic tables as well as other sturdy outdoor objects like playhouses and storage bins.
That being said, what are the pros and cons for you using HDPE & MDPE containers for your products?
I hope I didn’t bore you today! Check back in tomorrow for the next plastics on our list, PVC (Polyvinyl chloride)!
