Problems with blades that occur in production equipment for cutting adhesive films and adhesive tapes can be solved with a non-stick coating for the blades.
Are there any issues with adhesive sticking to the "cutting blades" or "cutter blades" of production equipment and packaging machines, impairing cutting performance or contaminating products? If cutting tools are used on sticky materials or items with adhesive, failing to implement "anti-adhesion measures" can negatively impact profits. Yoshida SKT offers coatings that can solve such problems. ■ Examples of solutions with blade coatings: - Cutting of resin packaging films - Punching of urethane rubber - Continuous cutting of product packages - Prevention of adhesion during adhesive tape cutting ▼ Click here to learn about surface treatments (coatings) that improve the cutting process ▼

Applications/Examples of results
【Case Study】 Continuous Cutting Process of Multi-layer Film ■Problem There is an adhesive layer on the first layer of the film, causing adhesive to stick to the rotary blade. This adhesion leads to cutting defects and line stoppages. ■Challenge To create a blade that can cut continuously without adhesive sticking to the rotary blade, a coating that prevents adhesion with excellent release properties and durability was required. Initially, a Bi-Coat® with superior durability and release properties was selected. The film thickness was about 10μm, and there was no visible change in the blade, but when actually tested, the cutting performance deteriorated to an unusable state. Next, a silicone-based coating that would have minimal impact on the blade edge shape was proposed, but due to the high adhesive strength of the adhesive layer in the multi-layer film, while cutting was possible, adhesion problems occurred. ■Adoption Process and Effects The rotary blade presses the edge against the film and cuts through pressure, resulting in minimal friction with the product. Therefore, MRS-004, which has excellent release properties and tackiness despite being a thin film, was proposed. As a result of testing, it was possible to maintain cutting performance without any change in the edge shape while continuously resolving the problems.
