1. Overview of PET Plastic and PETG Plastic Properties

•  Properties of PET Plastic

PET Plastic is lightweight, highly transparent, and has excellent gas barrier properties. It is mainly used in food and beverage packaging. However, its poor heat resistance and impact resistance limit its applicability in certain packaging needs.

•  Properties of PETG Plastic

PETG Plastic adds a copolymer component to PET Plastic, which has higher impact resistance and better processing performance.

1.1 Why PETG Plastic is More Popular than PET Plastic—Performance Advantages

1.1.1 Impact Resistance

PETG Plastic has better impact resistance than PET. It is suitable for packaging fragile or high-value items. The excellent impact resistance of PETG Plastic reduces the breakage of finished products during secondary processing, transportation, installation and use, greatly reducing the overall cost of finished products.

1.1.2 Excellent processing performance

Unlike PET, PETG Plastic is suitable for a variety of processing technologies, including injection molding, blister molding, extrusion molding, etc. This allows manufacturers to use PETG Plastic to create finished products in a variety of shapes and achieve details that are difficult to achieve with PET.

1.1.3 Environmentally friendly

PETG Plastic base materials are all environmentally friendly materials and meet food contact management requirements.

1.1.4 Weather resistance

PETG Plastic provides excellent weather resistance, which can maintain the toughness of the product and prevent yellowing. It also contains UV absorbers that can be co-extruded into a protective layer to protect the material from the harmful effects of UV rays.

1.2 Applications of PETG Plastic—Why It Appeals to Specific Industries

1.2.1 Food and Beverage Packaging

PETG Plastic's nontoxicity and chemical resistance make it suitable for food-grade applications. It is often used in the packaging of beverages, ready-to-eat foods, and snacks to meet high transparency and safety requirements.

1.2.2 Medical Devices and Cosmetic Packaging

PETG Plastic's high transparency and chemical resistance make it suitable for medical and cosmetic packaging. It can effectively protect products from contamination, better display product appearance, and make products both functional and aesthetic.

2. Choosing the Right Plastic for Your Product: PETG Plastic or PET Plastic?

Choosing PETG Plastic or PET Plastic depends on your cost, use, environmental protection and other factors. PETG Plastic is suitable for products requiring high transparency, flexibility and impact resistance, while PET Plastic is suitable for rigid and lightweight applications. PETG Plastic is more expensive than PET Plastic, so you need to weigh your costs as well.
