Why flexo dominates corrugated container production: Insights from Keshenglong & Shinko

Overview of corrugated printing processes

When printing on corrugated materials, each method has its advantages and disadvantages. Flexo printing remains superior to alternative printing methods because it offers maximum efficiency and versatility.

Common printing methods in the packaging industry

The packaging industry relies on three main printing methods, which include lithography, digital printing, and flexography. High-quality products are standard with lithography, but this method produces unpredictable results when working on uneven corrugated surfaces. Low production speeds mean that digital printing is only suitable for short runs and customized jobs.

Why flexographic printing stands out

The combination of speed and adaptability with cost effectiveness makes Flexo the preferred solution for corrugated printing. Relief plates made from flexible materials, together with fast-drying inks, enable the printing process to work efficiently on a variety of materials, particularly the rough and porous surfaces found on corrugated board. The ability of the printing process to maintain high production volumes while maintaining quality is the main factor that allows it to lead the market.

The advantages of flexo printing

Flexographic printing dominates corrugated container production due to its exceptional advantages. Manufacturers around the world choose flexo printing because of its distinct advantages.

Speed and efficiency in high-volume production

Flexo printing is characterized by its high speed of operation. Modern flexo presses for corrugated boxes produce thousands of containers per hour to serve large packaging operations. For companies that rely on fast and reliable shipping, this efficiency is vital to their operations.

Versatility on corrugated surfaces

The uneven surface of corrugated board, with its ridges and grooves, is a challenge for conventional printing equipment. Flexo printing solves this problem by using flexible plates that conform to any surface to ensure even ink application and vibrant colors on printed materials.

Cost-effectiveness for packaging manufacturers

Businesses need to keep a close eye on their costs. The unit cost of flexo printing remains lower than alternative methods for high-volume production. The use of water-based inks combined with waste reduction helps companies reduce the cost of printing corrugated containers.

Environmentally friendly and sustainable printing

The packaging industry is currently grappling with the issue of sustainability. The environmental trend supports flexographic printing because it uses water-based inks instead of solvent-based alternatives, which are less damaging to the environment. The production process results in less waste, which supports environmentally friendly production methods.

Key components of a flexographic printing press

The effectiveness of flexo printing can be explained by examining the individual components within a corrugated flexo press. All machine components function as essential elements to produce high-quality printed output.

Anilox Rollers

The process of transferring ink to printing plates depends on anilox rollers. The anilox rollers have engraved cells that maintain exact ink volumes for consistent coverage and bright colors. Anilox rollers are fundamental elements of flexographic printing presses because their quality determines the final print result.

Plates and dies

The flexible nature of rubber and photopolymer materials in flexo plates allows them to conform to corrugated surfaces. Companies can customize these plates to create complex logos and text, as well as detailed patterns, to effectively brand their packaging.

Drying systems

The ink requires a fast drying time to prevent smudging and ensure long-lasting results. Modern flexo presses are equipped with advanced drying systems, such as UV or hot air dryers, which speed up the process without compromising print quality.

Applications of flexographic printing in corrugated containers

The versatility of flexography makes it suitable for a wide range of applications in the packaging industry.

Retail packaging

The competitive retail market relies heavily on packaging to attract shoppers into stores. Flexographic printing gives brands the ability to create clever packaging that makes products stand out to shoppers, increasing brand visibility.

Shipping and Logistics

The durability of corrugated shipping containers must match the need for clear labeling. Flexographic printing provides clear and legible printing of barcodes, handling instructions, and other important information on rough surfaces.

Customised packaging solutions

Businesses use flexography to develop special solutions through seasonal artwork and limited-edition packaging to meet their individual needs. The flexible and efficient nature of the technology makes it suitable for businesses of all sizes.

Future trends in corrugated printing

The packaging industry follows technology as it evolves. The future of flexography, like the rest of the industry, is being shaped by new innovations.

Advancements in flexo technology

Flexography is undergoing a digital transformation that is speeding up makeready and increasing the accuracy of color quantities. New automation technologies are appearing in various production areas to reduce costs and improve operational efficiency.

Growing demand for sustainable packaging

The growing emphasis on sustainability provides an excellent opportunity for flexographic printing to satisfy both consumer and commercial customers. The market adoption of flexo printing technology will continue to grow through the use of energy-efficient equipment and environmentally friendly inks.
