Can BOPP colored thermosensitive synthetic paper be used for food packaging?

BOPP colored thermosensitive synthetic paper can be used for food packaging, but its specific use still needs to consider factors such as production process, coating formula, and compliance with food safety standards. The following is a detailed analysis of the use of BOPP colored thermosensitive synthetic paper for food packaging:

1、 Characteristics of BOPP color thermistor synthetic paper

Lightweight and easy to carry: BOPP film has a relatively light weight, making BOPP color thermal synthetic paper also lightweight and easy to carry and transport.

Good dimensional stability: During the biaxial stretching process, the molecular chains of BOPP film are arranged in an orderly manner, making the film have excellent dimensional stability and not easily deformed. This characteristic is also retained in BOPP color thermal synthetic paper.

High mechanical strength: BOPP film has the characteristics of high tensile strength and high elastic modulus, which makes BOPP color thermosensitive synthetic paper also have excellent tear strength and bending fatigue resistance.

Transparency and glossiness: BOPP film has high transparency, and BOPP colored thermal sensitive synthetic paper can clearly display the background of images or text on its transparent substrate before being subjected to thermal reactions. At the same time, the glossiness of BOPP film is usually greater than 85%, which enables BOPP color thermal sensitive synthetic paper to present a more high-end and attractive visual effect during printing and use.

Rapid thermal response: The thermal sensitive coating on the surface of BOPP colored thermal sensitive synthetic paper can quickly undergo a chemical reaction when heated, producing colored images or text, suitable for occasions that require rapid printing and marking.

Colorful and durable: Due to the special formula and processing of the thermal sensitive coating, BOPP colored thermal sensitive synthetic paper produces bright and durable colors after heating.

Environmental Protection and Safety: BOPP film and thermosensitive coating materials meet safety and environmental protection requirements, are non-toxic, odorless, and tasteless, and are suitable for applications that come into direct contact with food and drugs.

2、 Application of BOPP color thermistor synthetic paper in food packaging

BOPP color thermosensitive synthetic paper, with its excellent physical properties and chemical stability, as well as environmental protection and safety, can be used in the field of food packaging. Especially its waterproof, oil resistant, and wear-resistant properties make it perform well in some food packaging scenarios that require high label durability. For example, it can be used to print food labels, production dates, shelf life, and other information, ensuring clear visibility and long-lasting retention of food information.

3、 Precautions for use

Although BOPP colored thermosensitive synthetic paper can be used for food packaging, the following points should still be noted during actual use:

Ensure compliance with food safety standards: When selecting BOPP colored thermal synthetic paper, it should be ensured that it complies with relevant food safety standards to avoid contamination of food.

Pay attention to storage conditions: BOPP color thermosensitive synthetic paper should be stored in a dry and cool environment, avoiding prolonged exposure to sunlight, high temperatures, or humid conditions to avoid affecting its printing effect and durability.

Reasonable use and recycling: During use, relevant instructions and recommendations should be followed to ensure that BOPP color thermal synthetic paper can achieve the best printing effect and durability. At the same time, when disposing of waste, its recyclability should be considered to reduce its impact on the environment.

In summary, BOPP colored thermosensitive synthetic paper can be used in the field of food packaging, but its specific use still needs to consider factors such as production process, coating formula, and compliance with food safety standards. Under the premise of ensuring compliance with relevant standards and requirements, BOPP colored thermal sensitive synthetic paper will provide a more diverse, efficient, and environmentally friendly solution for the food packaging industry.
