Direct printing on packaging materials presents significant engineering challenges, with web speeds reaching 300 meters per minute and position accuracy requirements of ±0.1mm needed for consistent quality. Traditional pre-printed materials require large inventories and lead times, while real-time printing demands precise synchronization between material transport, print heads, and curing systems.

The fundamental challenge lies in maintaining print quality and registration accuracy at high production speeds while accommodating variations in substrate properties and environmental conditions.

This page brings together solutions from recent research—including speed-responsive printing systems, synchronized thermal printing on dual sides, sensor-based position error compensation, and UV-curable ink formulations. These and other approaches focus on achieving reliable, high-quality printing while reducing waste and inventory costs in production environments.

1. Packaging Design with Shape Maintenance and Use-Indicative Illustrations

UNI-CHARM CO LTD, Unicharm Corporation, 2024

Packaging design that makes it easier for users to choose and use the right products by providing clear indicators of intended use and target users. The packaging has features like shape maintenance, clear condition after opening, and illustrations that match the product's intended use and user demographics. This reduces the risk of mistaken selection or misuse.

2. Pill Packaging Inspection System with Defective Pill Detection and Labeling Inspection Mechanism

Smart Link Co., Ltd., 2024

Pill packaging inspection system that automatically detects and removes defective pills during packaging to prevent damaged pills from reaching consumers. The system has a pill supply unit, transfer unit, inspection unit, and packaging department. The labeling inspection device in the packaging department checks for printing defects on the pill packaging labels. If defects are found, it stops packaging and separates the faulty packs. The device can detect issues like typo errors, number omissions/additions, and label position swaps.

3. Form-Fill-Seal Packaging Machine with Dual-Sided Synchronized Thermal Printing on Common Film

ISHIDA CO LTD, Ishida Co., Ltd., 2024

Form-fill-seal packaging machine that allows using a common film for different products without needing separate pre-printed films. The machine prints product information on both sides of the film before forming bags. This eliminates the need for different films with pre-printed labels for each product. The printing is synchronized with film transport and can be done with a single printer head. The printed areas are adjacent or integrated to avoid needing separate printer heads for each side. The printer contacts the heated areas for thermal printing.

10. Roll-Fed Packaging Machine with Sectional Web Printing and Position Error Compensation

TETRA LAVAL HOLDINGS & FINANCE SA, TETRA LAVAL HOLDINGS & FINANCE S A, 2024

Reducing costs of traceability in roll-fed packaging machines by printing product codes on sections of the web instead of individual packages. The web is printed with alternating patterns on sections using multiple printing plates. The sections are folded into packages downstream. This allows using regular flexographic printing instead of expensive digital printing. The machine compensates for web position errors by comparing registered section codes to estimated positions.

11. Standing Pouch Packaging Device with Separate Gripping and Imprinting Mechanisms Using Movable Close Contacts and Detachable Type Block

Lee Jae-wan, 2024

Standing pouch packaging device that can clearly imprint letters or numbers on the sealed portion of the pouch using an imprinting member.

This allows customization options like dynamic printing placement and size variation based on box size, while minimizing throughput limitations from complex repositioning movements between functions. The system also enables features like box erection and automated transfer.

13. Resin Sheet Packaging Container with Laser-Induced Black Markings on Titanium Dioxide Core Layer

LISPACK CO LTD, Rispac Co., Ltd., 2024

Packaging container with clear markings and reduced labels by laser marking a core layer containing titanium dioxide. The container is made from a resin sheet with a core layer containing titanium dioxide. Laser marking using carbon dioxide irradiates the titanium dioxide to create black markings on the container. The contrast between the white core and black markings makes the markings stand out. Laser marking instead of labels reduces label usage. The core layer covered by a thin transparent skin layer prevents surface damage from laser irradiation.

14. Packaging Box with Linear Identification Marks for Visual Product Differentiation in Stacked Arrangements

MITSUBISHI ELECTRIC CORP, Mitsubishi Electric Corporation, 2024

Packaging box design for easily and visually identifying products when stacked. The box has identification marks on one side that allow visual differentiation between products when multiple boxes are stacked. The marks are arranged with equal distances from vertical and horizontal lines on the side. The marks are continuous or discontinuous linear shapes that extend along the lines. The type of product is identified by the number of mark components lined up along the vertical lines. This allows stacked boxes to be easily visually distinguished by the number and pattern of marks on the side.

15. Layered Packaging Material with Urethane Resin-Based Light-Blocking and Adhesive Printed Layers

ARTIENCE Co., Ltd., ARTIENCE Co., Ltd., ARTIENCE CO LTD, 2024
