Achieving stable adhesion with printing inks and resins! We respond according to your desired materials and adhesion strength!

The "Easy Adhesion Coating" is a surface treatment that applies a coating to various form surfaces to enhance the adhesion between the film surface and the coating resin or ink. By applying this treatment to films with low adhesion performance to coating resins or inks, stable adhesion can be achieved. We can respond to your desired materials and adhesion strength as needed. Combinations with other processed products (such as annealing) are also possible. We can accommodate small lots, so please feel free to consult with us. 【Features】 ■ Excellent adhesion to various printing inks ■ Excellent adhesion to various resins ■ Usable for UV inkjet printing ■ Compatible with screen printing and offset printing ■ Can also provide anti-static performance to easy adhesion surfaces ■ Capable of handling small lots *For more details, please feel free to contact us.

By directly imparting antistatic properties to the coating mat layer, we solve the issues of sustainability and stability in products that were difficult to address with conventional methods.

Otsuki Industries has developed a "static electricity prevention performance coating mat" that directly incorporates antistatic properties into the coating mat layer. Until now, products have been processed by applying a coating mat followed by an antistatic coat on the surface of the coating mat to impart antistatic effects. The products obtained through this process have certain performance characteristics and are used in various applications, but they have faced challenges in terms of sustainability and stability. This development aims to solve such issues! ★ Scheduled to be exhibited at the Functional Coating Fair 2017 on December 5th! We look forward to your visit. 【Features】 - Excellent sustainability of antistatic performance - Excellent heat resistance - Excellent water resistance - Excellent chemical resistance *For more details, please contact us or download the PDF.

We assist with diverse needs using precise coating technology! Leave the processing of surface treatments for film materials to us.

Otsuki Industrial Co., Ltd. has applied its unique technology, cultivated through the coloring process of gold and silver threads, to the field of industrial materials, working on coating processes for web materials that can meet a wide range of demands. We always think together with our customers and engage in custom-grade manufacturing tailored to their requirements. Since this is the primary processing of web materials, there may not be anything visible as the "form" of the final product, making it difficult to imagine the nature of our work. However, utilizing the know-how we have developed so far, we will continue to respond to diversifying needs. 【Business Content】 ■ Surface coating processing based on film, primarily polyester film ■ Annealing processing, corona treatment, coating matte, release coating, easy adhesion coating, coloring coating, antistatic coating *For more details, please refer to the PDF materials or feel free to contact us.

Improved wettability and adhesion of the adhesive! Corona treatment to enhance the substrate surface.

"Corona treatment" is a surface treatment technology that modifies the surface of substrates such as plastic films through corona discharge irradiation. By applying corona treatment, the surface of the substrate is modified, improving the wettability and adhesion of inks, coatings, adhesives, and other materials. Generally, plastic films have low surface tension, which often leads to issues such as poor adhesion during printing or coating. However, when corona treatment is performed, the surface tension of the substrate is significantly increased, enhancing adhesion. 【Features】 ■ Corona discharge irradiation ■ Significant improvement in surface tension of the substrate ■ Enhanced wettability and adhesion ■ Compatible with materials other than PET films ■ Capable of handling small lots *For more details, please refer to the catalog or feel free to contact us.

"Those who want to prevent deformation due to heat" and "Those who want to stabilize dimensions and shapes" should definitely take a look! We also explain what kind of processing it is and what applications it can be used for.

Typically, when heat is applied, the substrate shrinks significantly. However, by performing "annealing" heat treatment in advance, the amount of shrinkage is reduced, and the substrate hardly shrinks even when heat is applied. "Annealing" is a surface treatment that dramatically improves thermal dimensional stability in subsequent processes by applying heat treatment to various films. ▼ A must-see for those facing the following issues: - I want to prevent substrate shrinkage... - I want to improve dimensional stability... - I want to eliminate distortion (reduce residual stress)... Here, we explain the following: 【Table of Contents】 ■ What is annealing? ■ Examples of applications ■ Features ■ Representative physical properties *For more details, please refer to the catalog or feel free to contact us.

Riyadh, December 28, 2025 - (JCN Newswire) - One of the main events of Riyadh Season 2025, "The Ring V: Night of the Samurai," was held on the 27th at the Mohammed Abdu Arena in Boulevard City. In the main event of the tournament, Japan's champion Naoya Inoue defended his super bantamweight world title against Mexican challenger Alan Picasso, winning by a unanimous decision of 3-0 and securing victory in a world-class match. The event opened with the performance of the Saudi Arabian national anthem, signaling the start of a night filled with high-level competition. The main event began cautiously, with both fighters gauging distance and timing in the first round. In the second round, Inoue took control with a series of powerful punches, and in the third round, he continued to gain an advantage with clean left hits. The fourth round saw both fighters heightening their caution, leading to a closely contested exchange of attacks.
