Plastic Quality Number Checker | Identify Resin Codes & Safety

♻️ Plastic Quality Number Checker

Identify resin identification codes (1–7). Understand safety, recyclability, and environmental impact of each plastic type.

✨ Select a plastic number and click “Check Quality”

📋 Plastic Quality Number Checker: Complete Guide to Resin Codes

The plastic quality number checker helps you decode the resin identification code (RIC) found inside the triangular recycling symbol on most plastic products. Understanding these numbers — from 1 to 7 — empowers you to make informed decisions about safety, recycling, and environmental footprint. Whether you’re checking a water bottle, food container, or kids’ toy, this tool provides instant, science-backed insights.

🔢 What Do the Plastic Numbers Mean?

#1 PET #2 HDPE #3 PVC #4 LDPE #5 PP #6 PS #7 Other

Each number indicates the type of plastic polymer used. Plastic quality number checker tools evaluate factors like heat resistance, leaching risk (e.g., BPA, phthalates), and recyclability. Numbers 1, 2, and 5 are generally considered safer for single-use or repeated use; #3 PVC and #6 PS pose higher health risks; #7 often contains polycarbonate with BPA unless labeled “BPA-free”.

♻️ Recycling & Environmental Impact

Recycling facilities accept plastics based on their resin codes. Plastic quality numbers #1 (PET) and #2 (HDPE) have the highest recycling rates. #5 PP is increasingly recycled, while #3, #6, and #7 are rarely recycled in curbside programs. Using this checker helps reduce contamination and supports proper waste sorting.

⚠️ Health & Safety Guidelines

For food and drink storage, avoid reusing #1 (PET) bottles as they can harbor bacteria and may leach antimony. #3 PVC contains phthalates — never heat. #6 PS can release styrene, especially with hot food/drinks. #7 “Other” may include BPA, linked to hormonal disruption. Our plastic quality number checker gives clear safety notes for each category, so you can protect your family and the planet.

📌 How to Use the Plastic Number Checker

Simply select the number visible inside the chasing arrows symbol on your plastic item (usually at the bottom of containers). Click “Check Plastic Quality” to see its full description, safety rating, and recycling guidance. Perfect for households, educators, and eco-conscious consumers looking for reliable plastic identification.


🧾 Plastic Resin Code Summary Table

  • #1 PET (Polyethylene Terephthalate): Soft drink & water bottles. Single-use recommended. Safe but avoid reuse.
  • #2 HDPE (High-Density Polyethylene): Milk jugs, shampoo bottles. Very safe, widely recycled.
  • #3 PVC (Polyvinyl Chloride): Pipes, cling wraps. Contains phthalates – avoid food contact when heated.
  • #4 LDPE (Low-Density Polyethylene): Grocery bags, squeezable bottles. Safer but less recycled.
  • #5 PP (Polypropylene): Yogurt cups, medicine bottles. Heat-resistant, microwave-safe, BPA-free.
  • #6 PS (Polystyrene): Styrofoam cups, takeout containers. Potential carcinogen risk; avoid hot contents.
  • #7 Other (e.g., Polycarbonate, PLA): Baby bottles, 5-gallon water jugs. May contain BPA or be bioplastic – check labels.
