Resin code for plastic

Resin code for plastic, also known as resin identification codes, are used to identify the type of plastic resin used in a product. These codes, usually found on the bottom of plastic containers and products, help in the sorting and recycling process. Here are the resin identification codes for various types of plastic:

1. Polyethylene Terephthalate (PET or PETE)
   • Resin Code 1
   • HS Code: 3907.61
   • Common uses: Beverage bottles, food containers, and textile fibers.
2. High-Density Polyethylene (HDPE)
   • Resin Code 2
   • HS Code: 3901.20
   • Common uses: Milk jugs, detergent bottles, and plastic bags.
3. Polyvinyl Chloride (PVC)
   • Resin Code 3
   • HS Code: 3904.10, 3904.21, 3904.22
   • Common uses: Pipes, flooring, and medical equipment.
4. Low-Density Polyethylene (LDPE)
   • Resin Code 4
   • HS Code: 3901.10
   • Common uses: Plastic bags, shrink wrap, and flexible packaging.
5. Polypropylene (PP)
   • Resin Code 5
   • HS Code: 3902.10
   • Common uses: Bottle caps, straws, and food containers.
6. Polystyrene (PS)
   • Resin Code 6
   • HS Code: 3903.11 (expandable), 3903.19 (other)
   • Common uses: Disposable coffee cups, plastic food boxes, and protective packaging.
7. Other Plastics (including polycarbonate, acrylic, nylon, etc.)
   • Resin Code 7
   • HS Code: Varies by specific material (e.g., Polycarbonate: 3907.40, Nylon: 3908.10)
   • Common uses: Eyewear lenses, water bottles, and various specialty products.

Using Resin Codes

These resin identification codes are typically depicted as a number inside a triangular recycling symbol, usually found on the bottom of plastic products. Here’s a brief overview of each code:

1. PET or PETE (Resin Code 1): Commonly recycled, used for single-use beverage bottles and food containers.
2. HDPE (Resin Code 2): Widely recycled, used for products that require rigidity and durability, like milk jugs and detergent bottles.
3. PVC (Resin Code 3): Less commonly recycled, used for pipes, clear food packaging, and shrink wrap.
4. LDPE (Resin Code 4): Often recyclable, used for plastic bags, grocery bags, and some food wraps.
5. PP (Resin Code 5): Recyclable, used for bottle caps, food containers, and straws.
6. PS (Resin Code 6): Sometimes recyclable, used for disposable coffee cups, plastic food boxes, and protective packaging.
7. Other (Resin Code 7): This category includes various other plastics like polycarbonate and acrylic, which are used in a wide range of products. Recycling options vary widely for these materials.

Conclusion

Understanding resin codes is essential for proper recycling and waste management. These codes help consumers and recycling facilities identify the type of plastic, ensuring that it is processed correctly. Always check local recycling guidelines to see which types of plastics are accepted in your area.
