Once the prepress setup is complete, the raw paperboard enters the printing process, where the choice of technology is dictated by the project’s scope. Flexographic printing, characterized by its efficiency and adaptability, is favored for medium to large runs. This method allows manufacturers to apply vibrant colors and patterns while facilitating quick transitions between jobs. In contrast, gravure becomes indispensable for longer production cycles where print consistency and detail are critical, optimizing press speed and image reproduction.
As digital technology has surged, digital printing serves as a complementary method, especially ideal for short runs or personalized orders, such as limited edition buckets with variable data contexts like promotional QR codes. Although this method alleviates the costs and time associated with plate creation, the need for food-safe inks and coatings underscores the importance of careful material selection and adherence to safety regulations in all forms of printing.
Post-printing, the application of inks and drying techniques is essential to ensure a product’s durability and safety. Inks must be certified for food contact to mitigate any risks associated with food products stored in these containers. Various drying systems, including ultraviolet (UV) and infrared (IR) curing, are employed, with UV curing gaining popularity due to its accelerated cycle times and higher gloss finish, which not only enhances visual appeal but also boosts resistance to scratches and impacts during later forming processes.
After printing, the coating and finishing phase introduces additional layers of protection and functionality. Here, coatings such as aqueous varnish and film lamination are utilized to create barriers against moisture and grease, crucial for maintaining the integrity of wet or oily food products. This phase focuses on sustainability as well, with a growing preference for mono-material coatings that facilitate recycling while ensuring product safety.
Once the printed and coated sheets are ready, the production line transitions to the die-cutting and creasing stage. Here, methods vary based on production volume and complexity. Flatbed die cutting is excellent for shorter runs and intricate designs, while rotary die cutting provides the speed necessary for vast quantities, seamlessly integrating with roll-fed printing setups. For prototyping unique shapes or designs, laser cutting offers versatility despite being slower for high-volume orders.
Subsequently, the forming and gluing of the bucket takes place. Blanks are assembled into the final product using folder-gluers or thermoforming stations, utilizing adhesives that are also food-safe to maintain compliance with food packaging regulations. Throughout this entire process, quality control and inline inspection are vital, ensuring that print registration, ink adhesion, and the structural integrity of seams meet stringent standards.
