What are the latest developments in the production technology of BOPP synthetic label paper?

The production technology of BOPP (biaxially oriented polypropylene) synthetic label paper has made significant progress in recent years. The following are some of the latest technological developments:

1、 Production line and equipment upgrade

Efficient production lines: In recent years, multiple highly efficient and automated BOPP film production lines have emerged worldwide. These production lines not only improve production efficiency, but also achieve precise control of the production process through integrated control systems, thereby enhancing product quality.

Intelligent management system: Some advanced BOPP film production lines have introduced technologies such as Industry 4.0 (Intelligent Production Management System) and Integrated Machine Control (IMC), achieving full process automation from feeding to finished product cutting. This intelligent management system can monitor various parameters in the production process in real time, ensuring the stability of product quality.

2、 Innovation in raw materials and additives

Environmentally friendly raw materials: With the increasing awareness of environmental protection, more and more BOPP film manufacturers are adopting environmentally friendly polypropylene resin as raw material. These environmentally friendly resins have lower volatile organic compound (VOCs) emissions and better biodegradability, which helps reduce environmental pollution.

Functional additives: In order to improve certain specific properties of BOPP film, such as anti-static, smoothness, anti adhesion, etc., manufacturers are constantly developing new functional additives. The addition of these additives can significantly improve the comprehensive performance of the film and meet the application needs of different fields.

3、 Production process optimization

Improvement of stretching process: In the traditional BOPP film production process, the control of stretching temperature and stretching ratio is a key link. In recent years, with the advancement of technology, manufacturers have optimized the stretching process, achieving precise control of film properties by precisely controlling the stretching temperature and stretching ratio.

Surface treatment process innovation: In order to improve the adhesion and composite strength of ink, the surface treatment process of BOPP film is also constantly innovating. For example, using new corona treatment techniques or plasma treatment techniques can significantly improve the surface wetting tension and printing suitability of thin films.

4、 Functional film development

UV resistant film: With the continuous expansion of outdoor applications, higher requirements have been put forward for the UV resistance performance of BOPP film. Manufacturers have successfully developed BOPP films with excellent UV resistance properties by adding UV resistant agents or using special production processes.

Barrier film: In order to improve the shelf life and safety of food, manufacturers have developed BOPP films with excellent barrier properties. These films can effectively prevent the penetration of substances such as oxygen and moisture, thereby extending the shelf life of food.

Other functional films: In addition, various functional BOPP films such as anti-static, anti adhesion, high transparency, and high gloss have been developed to meet the application needs of different fields.

5、 Environmental protection and sustainable development

Circular Economy: Driven by environmental policies, BOPP film manufacturers are exploring circular economy models. By recycling waste films and developing biodegradable films, the impact on the environment has been reduced.

Green production: During the production process, manufacturers continuously adopt new environmentally friendly technologies and equipment to reduce energy consumption and emissions. For example, adopting energy-saving drying equipment and optimizing production processes to reduce environmental pollution.

In summary, the production technology of BOPP synthetic label paper has made significant progress in recent years. These advances not only improve production efficiency, optimize production processes, and develop various functional films, but also promote environmental protection and sustainable development. In the future, with the continuous advancement of technology and the expansion of application fields, the production technology of BOPP synthetic label paper will continue to innovate and develop.
