Customer Profile

Chiyoda Gravure Corporation is one of Japan's leading converters specializing in flexible packaging, shrink sleeve labels, decorative films, and functional materials. With decades of experience serving consumer goods, beverage, household, and industrial markets, the company has built a strong reputation for delivering high-quality printed and converted products.

In addition to packaging applications, Chiyoda Gravure is actively involved in decorative and functional film solutions used across a wide range of industries. The company's commitment to technological innovation and manufacturing excellence has enabled it to remain a trusted supplier to many well-known consumer brands throughout Japan and overseas.

As market demand continues to shift toward greater product variety, shorter production runs, and stricter quality requirements, Chiyoda Gravure continues to invest in advanced manufacturing technologies that support both operational efficiency and product quality.

Business Challenge

Shrink sleeve labels require precise seam formation and consistent quality control throughout the production process. As production environments become increasingly diversified with more SKU variations and shorter production runs, maintaining stable seam quality while maximizing production efficiency becomes increasingly important.

For Chiyoda Gravure, the objective was not only to enhance production capability but also to strengthen quality assurance throughout the shrink sleeve converting process. Key requirements included improving seam consistency, reducing manual adjustment, enhancing inspection capability, and increasing productivity through more efficient roll handling and quality management.

To address these challenges, Chiyoda Gravure selected Webcontrol's advanced seaming and inspection solutions through its long-term partner, SOBU. In addition to providing local sales support, SOBU enables prompt communication, technical assistance, and after-sales service, ensuring that Chiyoda Gravure can receive timely support whenever needed and maintain stable production operations.

K2 Plus Shrink Sleeve Label Seaming Machine

To support stable and efficient sleeve production, Chiyoda Gravure invested in the K2 Plus Shrink Sleeve Label Seaming Machine, equipped with advanced automation features designed for modern shrink sleeve manufacturing.

• Auto Offset System

The Auto Offset System automatically compensates for seam position variations during production, helping maintain consistent overlap width and seam quality.

By reducing the need for manual adjustment, the system helps operators achieve greater process stability while minimizing material waste and improving production yield.

• Digital Oscillation

K2 Plus is also equipped with Digital Oscillation technology, providing precise and repeatable adjustment through a digital control interface.

This feature allows faster setup, simplified operation, and improved repeatability between production jobs, making it particularly suitable for environments that require frequent product changeovers and flexible manufacturing capabilities.

I2 Label Inspection Machine

To further strengthen quality assurance, Chiyoda Gravure also selected the I2 Label Inspection Machine as part of its shrink sleeve production workflow.

• Easy Inflation Check

One of the key features of the I2 system is the Easy Inflation Check function, which enables rapid verification of seam integrity.

The inspection process helps identify potential seam-related defects, including incomplete bonding or seam opening issues, providing an additional level of quality assurance before products are shipped to customers.

• Splice Detection

The I2 system is equipped with automatic Splice Detection functionality, allowing splice locations to be identified and managed during inspection.

This capability improves traceability throughout the production process while supporting downstream converting and customer quality requirements.

• Large Roll Handling Capability

Supporting roll diameters of up to Ø800 mm, the I2 system can accommodate large-size cores commonly used in shrink sleeve production. This capability provides greater flexibility in handling various roll specifications while supporting efficient inspection operations.

The result is improved operational efficiency, reduced downtime, and increased overall productivity.
