Development of Solvent-Free Composite Technology
In 2013, the solvent-free composite technology experienced rapid growth in China's flexible packaging industry. This process offers significant advantages such as environmental protection, energy efficiency, low cost, and no residual solvents, making it increasingly popular among manufacturers. By the end of 2013, over 467 units of solvent-free composite equipment were installed domestically, with companies like Nodmeike leading the market with around 200 units. Other notable players include Guangzhou Tongze and Shenzhen Tianle. The technology also started to gain traction in mainland China from Taiwan and other regions. It is expected that the installed capacity would grow by more than 30% in 2014, signaling a shift toward solvent-free methods becoming the industry standard. In terms of adhesives, both domestic and international brands have matured in the solvent-free sector. Foreign names like Henkel, Bostik, and Dow Chemical are widely used, while Chinese brands such as Kangda and Zhejiang New Oriental are also gaining ground. Most solvent-free composites currently produce two-layer structures, though some companies are experimenting with three-layer options. Despite its benefits, the process still faces challenges, including differences in appearance compared to traditional dry composites and lower performance in high-temperature or moisture-resistant applications. Non-Benzene Gravure Inks and Integrated Ink Usage
The shift from benzene-based inks to benzene-free alternatives represents a major advancement in the gravure and flexible packaging sectors. While large enterprises have adopted these eco-friendly inks, smaller businesses still rely on traditional options. Integrated inks are now widely used in large-scale flexible packaging operations and are seen as a key trend for the future. Some domestic ink manufacturers have invested in application labs to ensure better quality control and support for their clients. Heat Pump Technology in Printing and Drying
Heat pump systems are becoming a preferred choice for drying in the flexible packaging industry due to their energy efficiency and reduced emissions. Compared to coal-fired boilers, heat pumps can significantly cut heating costs. They are capable of providing both hot and cold air, meeting the needs of printing machines, laminators, and workshop cooling. The system works by compressing refrigerants to generate heat for drying and then using the same cycle to cool the environment, offering a sustainable and cost-effective solution. Emission Control of Organic Waste Gases
Emissions from printing and compounding processes remain a major environmental concern. While efforts are being made to adopt more eco-friendly printing techniques, the industry still relies heavily on solvent-based systems. However, the introduction of waste gas recycling technologies has shown promise, and more companies are expected to invest in such solutions in the coming years. Regulatory measures, such as those implemented in Beijing, are also driving stricter controls on emissions across various sectors. Solvent Supply Solutions
A growing number of solvent suppliers are catering specifically to the gravure printing industry, offering a range of solvents tailored for different drying speeds. These products are designed to be stable, safe, and cost-effective, helping flexible packaging companies improve efficiency and reduce expenses. Functional Films and Their Applications
The production of plastic films in China continues to grow steadily, with functional films playing an essential role in improving product performance and profitability. High-barrier films, multi-layer coextrusion technologies, and advanced materials are driving innovation in the sector. For example, new packaging materials developed by the Beijing Printing Institute enhance food safety by minimizing solvent residues. Companies are also exploring microwaveable, recyclable, and environmentally friendly films to meet evolving consumer demands. Environmental Labeling and In-Mold Labels
Eco-friendly labeling solutions, such as PETG and OPS, are gaining popularity. In-mold labels, although initially more expensive, offer long-term cost savings and labor efficiency. They are now widely used in industries like food and daily chemicals. Other Developments
Many companies are adopting online quality inspection systems to enhance product consistency and competitiveness. Additionally, the use of shaped bags and square pockets is increasing, reflecting broader trends in packaging innovation.
