What Do the Numbers on Plastics Mean?
Plastics make up the packaging of many products we use in daily life. Plastics, which are widely used in various packaging, products and many industrial applications, have many different types. Therefore, when not managed properly, they can cause environmental problems.
In order to reduce the negative impact of plastic waste on nature and to manage recycling processes in the best way, a coding system has been developed on plastic products. These numbers from 1 to 7 are used to determine the type of plastic material, the materials in which it is used and the recycling possibilities.

Plastic Numbers and the Environment: Conscious Consumption in Packaging Selection
Understanding what plastic numbers stand for offers consumers and industry professionals the opportunity to make a more informed contribution to sustainability efforts. In this way, it is the first step in taking conscious consumption steps for a sustainable future.
Let us now examine what the numbers on plastics mean.
- Polyethylene terephthalate (PET / PETE)
It is a type of polymer known as PET or PETE. This type of plastic is widely used in many industrial fields, especially beverage bottles, oil drums and water bottles. It is particularly suitable for use in disposable products. PET is known for being lightweight, durable and recyclable. This makes it an environmentally friendly packaging option.
High-density polyethylene ( HDPE veya HDP )
High-density polyethylene is a polymer known as HDPE or HDP. It is used in many industrial applications due to its high density, durability and chemical resistance. Experts recommend its use because it is a polymer that does not contact any chemicals with water. HDPE is especially preferred in many products such as water pipes, detergent bottles, plastic bags, milk cartons and toys.
Polyvinyl chloride ( PVC or V )
Polyvinyl chloride, also known as PVC or V, is one of the polymer varieties. It is known for its durability and versatile uses. It is therefore suitable for use in various industrial sectors such as construction, plumbing, electrical wiring, packaging materials and medical devices. However, due to the environmental concerns raised during the production and use of PVC, it is becoming increasingly important to search for and choose sustainable alternative materials.
Low-density polyethylene ( LDPE )
Low-density polyethylene, or LDPE, is a type of polymer. This plastic material is renowned for its low density, flexibility and transparency. For this reason, it is often preferred in areas such as plastic bags, packaging materials, inflatable toys and textiles. LDPE is more difficult to recycle than other types of plastic, but with various recycling technologies and conscious consumer behavior, a more sustainable use can be achieved.
Polypropolene ( PP )
The most reliable plastic among plastic types is PP. Polypropylene, PP for short, is a thermoplastic polymer. It is known for being lightweight, durable and chemically resistant, which is why it is used in many different applications such as automotive parts, packaging materials, textiles and medical devices. PP’s recyclability and energy-efficient production processes offer significant sustainability benefits.
Polystyrene ( PS )
Polystyrene, or PS, is a thermoplastic polymer. This material is characterized by its light weight, low cost and insulating properties. For this reason, it is frequently used in packaging materials, food containers, foam plates and disposable products. However, despite its wide use, PS is not suitable for sustainability due to its environmental impact and recycling challenges.
OTHER (O)
Number 7 represents the plastic “Other” category and includes various types of plastics. This number is denoted by the letter “Other” or “O”.
This category usually includes polycarbonate (PC) plastic. Polycarbonate is a type of plastic used mainly in products such as water bottles, baby bottles, optical lenses and some food containers. However, it raises concerns due to substances such as bisphenol A (BPA). In terms of sustainability, such plastics should be recycled and alternative materials should be preferred.
Conscious Steps in Recycling: The Role of Plastic Numbers
Recycling is critical to environmental sustainability and plastic numbers are guides to help us take informed steps in this process. Plastic numbers allow us to identify different types of plastics and choose appropriate recycling methods. In this way, consumers and industry professionals can make more informed choices to reduce the impact of plastic waste.
These conscious steps in recycling allow us to contribute to a more sustainable future by providing environmental benefits such as conservation of natural resources, energy savings and waste reduction. The role of plastic numbers is an important milestone for an environmentally friendly circular economy, which, together with greater awareness and education in this area, can lead to a more effective recycling process.
