1. Introduction

Plastic sheets are widely used in various industries due to their versatility and durability. APET, PET, PETG, and GAG sheets are some of the most commonly used types of plastic sheets. These sheets offer unique features and benefits that make them suitable for different applications. In this article, we will explore the key characteristics, applications, advantages, and disadvantages of these types of plastic sheets to help you make an informed decision.

2. What are APET, PET, PETG, and GAG Sheets?

APET, PET, PETG, and GAG sheets are all thermoplastic polymers commonly used in the packaging industry. These sheets are made from polyethylene terephthalate (PET) resin, which is a clear and robust plastic. Different sheets are produced by modifying the PET resin with various additives, resulting in other properties and characteristics.

APET sheets are made by adding glycol to the PET resin, which increases its clarity, strength, and chemical resistance. PET sheets are made by adding isophthalic acid or terephthalic acid to the PET resin, which improves its toughness and thermal stability. PETG sheets are made by adding glycol to the PET resin and modifying the molecular structure, resulting in improved impact resistance and easy fabrication. GAG sheets are made by adding glycol to the PET resin and cross-linking, enhancing flexibility and moisture resistance.

3. Characteristics of APET
