3. Types of PET Plastic 1 available on the market

Today, PET plastic number 1 is divided into three main types, each with distinct characteristics and applications suitable for different market needs:

3.1 Virgin PET 1

This is new PET plastic that has not been used or recycled. Virgin PET has high purity, ensuring safety and quality for products in direct contact with food and beverages. It is commonly used in bottled water, soft drinks, and premium food packaging.

3.2 Recycled PET 1

Recycled PET is made by blending virgin PET with recycled or used PET that has been processed. It retains many beneficial properties while offering a lower cost compared to virgin PET. Recycled PET is commonly used in products that do not require high transparency or absolute safety, such as cooking oil bottles and industrial plastic containers.

3.3 Scrap PET 1

Scrap PET refers to used PET plastic recovered from bottles, jars, or other plastic items. It needs to be treated, cleaned, and recycled before reuse. Scrap PET is often used as raw material for recycled plastic products such as polyester fibers, construction materials, or plastic items not in direct contact with food.
