3.Digital Printing technology in packaging printing
Individualized packaging design: Digital printing technology makes packaging design more personalized, customizing unique packaging appearance to customer needs and enhancing brand image.
Short-run printing: digital printing can flexibly respond to small batch orders, meet the market demand and reduce inventory pressure.
Printing effect improvement: Digital printing technology can achieve higher resolution and printing accuracy, providing clearer and fuller printing effect and increasing the attractiveness of products.
Fast delivery: Digital printing does not require plate-making and printing preparation time, which can quickly start production, shorten the delivery times and improve customer satisfaction.
In the field of flexible packaging, common ink types for digital printing include water-based ink and solvent inks, which have different features and range of application:
Water-based ink is a kind of eco-friendly ink, which is composed of water, pigments, additives and colloids. Its main features include:
• Eco-friendly: Water-based ink does not contain harmful solvents, it’s eco-friendly and in line with environmental laws and regulations
• Less smell: Water-based ink has a lighter smell than solvent ink, which is suitable for packaging with higher requirements of smell.
• Applicable materials:It is suitable for materials such as paper and cardboard with good absorption.
Solvent inks usually use organic solvents as media and have the following features:
• Water resistance: Solvent ink has good water resistance after printed and is suitable for packaging materials required waterproof treatment.
• Applicable materials: it’s suitable for all kinds of materials, including plastic film, metal foil, composite materials, etc., and widely used in flexible packaging.
Digital printing materials for flexible packaging mainly include:
Plastic film: Digital printing can be applied to a variety of plastic films, including polyethylene (PE), polypropylene (PP), polyester (PET), etc. These materials are often used in food packaging, medicine packaging and other flexible packaging.
Aluminum foil: Aluminum foil is often used in coffee packaging, medicine packaging and so on. It has good moisture, light insulation performance, suitable for those sensitive products required resistant of light, oxygen and moisture.
Composite materials: Various composite materials are often used in flexible packaging, including paper-plastic, aluminum-plastic composite film etc, which combine the features of different materials to make packaging more functional.
4. Digital printing technology in sustainable packaging
Reduce garbage and waste: Digital printing can flexibly produce according to actual demand, so as to reduce the unnecessary inventory and realize customized production.
Application of eco-friendly materials: Digital printing can use a variety of eco-friendly materials, such as degradable ink, recycled paper, etc., to reduce environmental pollution and facilitate the sustainable development of the packaging industry.
Energy saving and emission reduction: Compared with traditional printing technology, digital printing saves a lot of energy and reduces carbon emissions, reducing the impact on the environment.
5. Challenges and Opportunities
Technical challenges: Digital printing technology still needs to be constantly innovated and improved, so as to meet higher printing requirements, such as larger printing specifications and faster printing speed, etc.
Cost control: The costs of digital printing equipment and consumables are relatively high, how to reduce production costs and improve competitiveness is a problem to be solved.
Market competition: With the popularity of digital printing technology, market competition will be more intense. Enterprises have to improve the technology, quality and service constantly to maintain their competitiveness.
6. Conclusion and Prospect
The continuous development of digital printing technology has brought new opportunities and challenges to packaging printing. With in-depth research on the features and applications of digital printing technology and the concept of sustainable development, the packaging industry can be better to meet the market demand and improve its competitiveness. In the future, with the continuous maturity and popularization of digital printing technology, it is believed that packaging printing will usher in a broader development space to provide higher quality and more personalized packaging products for all walks of life.
