Nowadays, due to the increasing demand for environmentally friendly materials in fields such as architectural decoration, furniture manufacturing, and advertising signage, PETG decorative film, with its excellent performance, stands out in the highly competitive market and is highly favored. However, with the wide variety of products on the market, how consumers and buyers can scientifically choose high-quality PETG decorative film has become a matter of concern. Therefore, we interviewed some material experts to provide you with some professional advice.

What is PETG decorative film?

PETG (polyethylene terephthalate-1,4-cyclohexanedimethanol ester) is a non-crystalline copolyester material. PETG decorative film has high transparency, toughness, and impact resistance, and is easy to process and manufacture. Applications of PETG decorative film: PETG decorative film can be used for surface decoration of cabinets, wardrobes, interior doors, display cases, advertising light boxes, etc., and can replace materials such as PVC and acrylic.

1. Thickness and Weight

The thickness of PETG decorative film determines its performance and cost. Experts recommend choosing the appropriate thickness based on the application conditions: a thickness of 0.25-0.5mm is usually used for interior furniture decoration, etc.

2. Surface Treatment

The surface of PETG decorative film should be smooth and flat, without bubbles, impurities, or scratches. Surface treatment types: Common finishes include matte, frosted, and glossy, which can be selected according to decorative needs. When purchasing, you should touch the surface to feel its texture and observe its reflection effect on external light sources.

3. Environmental Certification and Safety Standards

Although PETG material itself is environmentally friendly, some additives may be added during the production process. Consumers should pay attention to whether the product has passed environmental certifications such as RoHS, REACH, and SGS (free of heavy metals or formaldehyde release). Especially for indoor use, it must comply with national standards for limits of harmful substances in interior decoration materials. 4. Adhesive Strength + Ease of Installation

Advantages of JSC A-34S compared to AFL CTO 63W: In different areas, the coating or bonding effect of PETG decorative film may not be ideal. If you are purchasing pressure-sensitive adhesive or hot-melt adhesive, please ensure that it has been certified for the substrate. Furthermore, you should ensure that the release liner has an appropriate peel strength for easy transfer, avoiding wrinkles, curling, and peeling.

Market Status and Purchasing Advice

Currently, there are many brands of PETG decorative films available on the market (including international leading brands such as 3M and LG, and some excellent domestic manufacturers). Prices range from a few yuan to several hundred yuan per square meter. Beware of low-price traps: excessively low prices may indicate insufficient thickness, inferior materials, or failure to meet environmental standards.

Experts advise consumers to follow these four steps when purchasing PETG decorative film:

• Visual inspection – surface smoothness and uniform light transmission

• Mechanical testing

• Tactile inspection: check for surface smoothness and uniform thickness

• **Odor test:** After removing the release liner, check for any pungent odor.

• **Performance testing:**  Request samples from the seller for bending tests and scratch resistance tests, etc.

Industry Trend Outlook

With the continuous improvement of environmental protection policies and consumer upgrading, PETG decorative film is entering homes due to its recyclability and lower VOC emissions compared to other technologies. Although PETG decorative film has already reached a market share of 40% in some regions, industry insiders predict that this new material will occupy more than half of the high-end decorative materials market within three years.

Consumers are advised to consider not only the price but also the product performance and environmental certifications when purchasing PETG decorative film, and to choose reputable brand manufacturers. Consumers should purchase from reputable channels and properly retain purchase receipts for future reference and to protect their rights.
