Biodegradable Substrates And New Substrate Applications

In the technological evolution of the screen printing and pad printing industry, material innovation is driving the overall improvement of environmental standards. The field of photovoltaic screen technology has achieved a breakthrough in ultra-fine printing precision of 8.5 microns. This improvement in precision enables environmentally friendly substrates such as biodegradable plastics to carry more complex graphic printing requirements. As a leading company in the photovoltaic screen segment, Kunshan Liangpin Screen Printing Equipment Co., Ltd.’s technical achievements show that ultra-precision fine-line printing screens have been successfully used in the production lines of photovoltaic power generation companies and battery factories.

Advances in ink technology provide critical support for the development of new substrates. Henderson has developed 250°C high-temperature home appliance in-mold injection inks and salt spray-resistant 30-year chip inks, with an annual R&D investment of 8-9 million yuan (accounting for 5% of sales). These products have been widely used in the production systems of well-known companies such as Panasonic, Sharp, Midea, Haier, and BYD. In the home appliance in-mold injection ink market segment, Henderson has occupied 70% of the market share, confirming the compatibility of high-performance inks with new printing materials.

Breakthroughs in environmental protection technology are reflected in multiple dimensions:

The application of solvent-free screen printing technology not only reduces VOC emissions, but also improves the adhesion of printed matter on degradable materials such as paper substrates.

Qingdao Haishuoda has passed the ISO9001 certified quality management system, ensuring the stability of environmental protection indicators in large-scale production.

The introduction of flexographic printing plates expands the range of printing suitability to more renewable material surfaces

In terms of substrate diversification, the industry shows obvious characteristics of specialized division of labor. The photovoltaic field requires highly stable screens that can withstand harsh environments, while the home appliance industry pays more attention to the high-temperature resistance of inks. This differentiated demand forces screen printing and pad printing companies to develop special material solutions for different application scenarios, such as the combination of ultra-precision screens and biodegradable materials, or the use of high-temperature inks and new composite materials.

Innovation in manufacturing processes and the application of environmentally friendly materials are forming a virtuous cycle. Chip ink technology that is resistant to salt spray for 30 years not only extends the life of electronic products, but also reduces the generation of waste caused by corrosion. The printing capability with a precision of 8.5 microns enables degradable materials to replace traditional plastic substrates to complete the marking and printing of precision electronic components. These technological advances jointly promote the development of the screen printing and pad printing industry in a more environmentally friendly and precise direction.
