[Packaging Machine Case Study] Wear-Resistant and Non-Stick Coating for Heat Sealers

A heat sealer that requires compatibility with packaging materials! Troubles are resolved with Bi-Coat, which combines non-stick properties and durability.

We will introduce examples of surface treatment in pillow packaging machines used for packaging food and pharmaceuticals. ■ Adhesion Issues with Heat Sealers The films used for pillow packaging vary in thickness and functionality depending on their application. In thicker packaging films that excel in preserving product quality, a resin that melts easily is used on the inner surface. When heat sealing, the resin on the sealing surface adheres to the heating part of the sealer, leading to issues such as product contamination. ■ Coating Used Bicoat "NYF-11-S" ■ Background and Effects of Adoption While plating treatment is often used to prevent adhesion on heat sealers, the soft, melted resin tends to stick to the heat sealer and does not come off. Fluororesin coatings were considered, but under high temperature and pressure conditions, there was a high risk of the coating peeling off, making it unsuitable for use. Yoshida SKT's Bicoat eliminates resin adhesion to the sealer due to its excellent release properties, and the high hardness coating with superior adhesion improves durability. This has led to a reduction in product defects and successful packaging using new materials. You can request a sample book of coatings suitable for sealers through the link provided.
