Resin identification code

Resin identification codes are the numbers and symbols that you see on many plastic products like water bottles, food containers, and toys. These codes tell you what type of plastic the item is made from, and can help you decide how to dispose of it properly.

There are seven different codes (numbered 1-7) that correspond to seven different types of plastic. Here's what they mean:

1. PET (polyethylene terephthalate): This is a type of plastic that is often used for drink bottles, food jars, and other containers that need to be clear and lightweight. You might see the code "PET" or the number 1 in the recycling symbol on the item.

2. HDPE (high-density polyethylene): This is a type of plastic that is used for items like milk jugs, laundry detergent containers, and plastic bags. It's a tough, rigid plastic that can be recycled easily. You might see the code "HDPE" or the number 2 in the recycling symbol on the item.

3. PVC (polyvinyl chloride): This is a type of plastic that is often used for pipes, shower curtains, and some medical devices. It's not as easily recycled as other plastics, so it's important to dispose of it properly. You might see the code "PVC" or the number 3 in the recycling symbol on the item.

4. LDPE (low-density polyethylene): This is a type of plastic that is used for some food packaging, trash bags, and squeezable bottles. It's a flexible plastic that can be recycled in some areas. You might see the code "LDPE" or the number 4 in the recycling symbol on the item.

5. PP (polypropylene): This is a type of plastic that is used for things like yogurt containers, bottle caps, and straws. It's a strong, lightweight plastic that is recyclable in many areas. You might see the code "PP" or the number 5 in the recycling symbol on the item.

6. PS (polystyrene): This is a type of plastic that is used for foam cups, take-out containers, and packing peanuts. It's lightweight but not easily recyclable in many areas. You might see the code "PS" or the number 6 in the recycling symbol on the item.

7. Other: This code is used for any plastic that doesn't fit into one of the other categories. It might be a composite of different plastics, or a plastic that is not commonly used. It's important to check with your local recycling facility to see if they accept this type of plastic.

So, next time you see a number in the recycling symbol on a plastic item, you'll know what it means! And remember, always recycle when you can and dispose of plastics properly to help protect our environment.
