Our Technology

Your partner for adhesive products supported by technology and quality

Our release liner sumilease can meet various performance requirements from customers.
A wide selection of paper substrates is available, including Wood-free paper (base paper for release liner), kraft paper, kurupak paper, crepe paper, and glassine paper. (Please inquire about recycled paper, various types of coated paper, composite substrates, etc.).
We can also respond to various requests for release agents by combining them according to the application, from light release to heavy release. In addition to silicone release agents, non-silicone release agents are also available.

Iwaki Factory

New product development and new technology development

We design and propose release liner that meets customers’ performance and quality requirements with short delivery times.
We have established a product development system in which the engineering and development divisions are located at the Iwaki Factory, the production base for sumilease , in order to coordinate with the sales and manufacturing divisions.

Our sales, development, and manufacturing divisions work together to constantly respond to customer needs and develop products quickly.
We respond quickly to the changing needs of our customers and develop new products and technologies.

Quality control/Quality assurance

Using a variety of testing and analysis equipment, we are sensitive to changes in product characteristics and strive to maintain and improve quality.
We implement quality assurance activities to supply stable products to our customers under an ISO 9001 system.
