Foreword: Identifying Plastic Types, A Three-Step Guide Hardware restoration is vital to protecting the environment. It reduces emissions, conserves resources, and prevents pollution. Knowing the proper steps is essential to make hardware recovery more accessible and practical. This guide will provide three simple steps for recycling plastic containers and explain how to further sub-categorize them according to the “Plastic Material Recycling Shipment Code” to ensure that plastics are properly recycled and reused.

Identifying Plastic Types


Identifying Plastic Types

  1.  (PET): Commonly used in beverage bottles, food containers, and shampoo bottles.
  2. (HDPE): Milk, detergent, and plastic bags.
  3.  (PVC): Floors, flooring, and window frames.
  4. (LDPE): Plastic bags, cling film, and bottle caps.
  5. (PP): Yogurt containers, heating containers, and bottle caps.
  6. (PS): No-wash utensils, CD cases, and instant noodle bowls.
  7. (Other): Quickly seen types of plastics, including polycarbonate (PC), polymethyl cellulose (PMMA), and biodegradable plastics.

Correctly sorted plastic containers are used for recycling because of dependence, and different kinds require different recycling procedures. Following these steps, you can find the right home for your plastic containers, help protect the environment, and promote sustainable resource utilization.


Mastering the art of accurate recovery categorization

How can you quickly identify the various types of plastics in the sea of plastics? Mastering the “Plastic Material Recycling Code” is the key. This set of numbers, composed of numbers, is equivalent to the plastic body of the certificate. It can accurately identify the material characteristics of different plastics to help us correctly categorize them to recover higher efficiency can be achieved.

According to the precision parts collection code, the common types of precision parts can be divided into seven categories:

  1. (PET): polyethylene terephthalate, widely used in beverage bottles and food containers.
  2. (HDPE): high-density polyethylene commonly used in milk and detergent bottles.
  3. (PVC): Polyvinyl chloride is used for pipes, raincoats, etc.
  4. (LDPE): low-density polyethylene used for plastic bags and cling film.
  5. (PP): Series is used for yogurt cups and barbecue grills.
  6. (PS): Polystyrene is used for no-wash utensils and foam bowls.
  7. (Others): Contains plastics other than those in the six categories or more, such as polycarbonate (PC), regulations, etc.

Understanding the characteristics and expected uses of these plastic products will help us correctly categorize plastic products in our daily lives, make recycling more accurate, and do our part for the environment.

Mastering Precision Part Dimensions to Simplify Precision Part Recycling

Knowing the plastic material recovery codes is the key to simplifying plastic recovery. Understanding these labels can help you accurately categorize your plastic containers to ensure they can be adequately recovered. These labels are usually on the bottom or side of the container and are triangular symbols of numbers and letters.

Standard plastic material return codes include:

  • PET (polyethylene terephthalate): commonly found in beverage bottles, salad containers, and peanut butter jars.
  • HDPE (High-Density Polyethylene): commonly found in milk, detergent, and water pipes.
  • PVC (Polyvinyl Chloride): Commonly found in raincoats, mattresses, and flooring.
  • LDPE (Low-Density Polyethylene) is familiar with squeeze bottles, food packaging, and plastic bags.
  • PP (series): familiar with yogurt cups, forged containers, and car bumpers.
  • PS (polystyrene): familiar with no-rinse dinnerware, CD cases, and insulation.
  • Other: Contains all types of plastics besides the six categories, such as sports equipment and sunglasses.

Knowing these symbols can help:

  • Sort the right plastics to ensure they can be recycled appropriately.
  • Reduce contamination at recovery centers and increase recovery efficiency.
  • Make a positive contribution to our environment and reduce plastic waste.

Keep in mind that different recycling programs may have different sorting regulations. Before you start recycling, check your local recycling program’s guidelines to ensure proper disposal of plastic containers.


Reach a verdict

Practicing the three steps of plastic recycling – rinsing, flattening, and sorting – not only gives plastics a new lease on life but also brings many benefits to our living environment. By sorting plastics, we can reduce waste, help recycle resources, and reduce the environmental burden.

Let’s do our part to recycle plastics; let’s start from our daily lives, dispose of plastics appropriately, sustain the earth’s resources, and keep the beautiful environment with us for generations.



What are the types of Plastic Recycling Identification Codes?

  • No. 1 is PET, No. 2 is HDPE, No. 3 is PVC, No. 4 is LDPE, No. 5 is PP, No. 6 is PS, and No. 7 is Others, which includes all types of plastics other than the above six.

How to properly flatten a plastic container?

  • Squeeze out the air from plastic containers and flatten them to the minimum size to save space and facilitate recycling.

Do I need to wash the plastic before recycling?

  • Yes, be sure to rinse out any remaining plastic containers to avoid contaminating other recyclables.
