Plastics are materials that play an important role in our daily lives. The classification of plastics can be divided in many categories, depending on different perspectives, such as classification by the chemical structure at the molecular level of plastic pellets, classification by the plastic molding process, and classification by the mechanical properties of the workpiece. However, the classification of plastics according to the international principles, which refer to the “International Plastics Identification Code” or the International Plastic Identification Code (IPIC) established by the Society of the Plastics Industry (SPI) in the United States. Such codes are often indicated on plastic products in the form of recycling symbols showing numbers 1 to 7 and a triangle to identify the type of plastic produced.

Plastic Identification Codes:

PETE (Code 1): PETE is commonly used in water bottles, beverage bottles, and food packaging.

 

HDPE (Code 2): HDPE is commonly used in the production of trash bins, oil bottles, detergent bottles, and water pipes.

 

PVC (Code 3): PVC is commonly used in water pipes, electrical wires, and construction materials.

 

LDPE (Code 4): LDPE is commonly used in plastic bags, plastic wrap, can lids, and water pipes.

 

LDPE (Code 4): LDPE is commonly used in plastic bags, plastic wrap, can lids, and water pipes.

 

PS (Code 6): PS is commonly used in plastic cups, food containers, and electrical appliance parts.

 

Other (Code 7): Others includes plastics are not classified under Codes 1-6, which may have additional sub-codes.

 

 

This code is useful in the recycling and waste management process, helping consumers and waste disposal conductor to better understand the types of plastic used in a given product. This is why this plastic classification standard has been popular and used to today. Just look for this symbol on your plastic product and you will find it. Plastic is closer than you think.
