High-durability fluororesin coating for sealers | Prevents film adhesion and improves durability
【Reduce downtime of high-speed continuous sealing lines】A tough coating that withstands high-temperature heating and high pressure! Strongly prevents adhesion of packaging film.
This is a technical case study for our unique high-durability fluororesin coating "Thermo Pro Release" applied to metal heat seal molds (seal bars, receiving molds, and crimpers) used in the packaging processes of food, pharmaceuticals, and daily necessities (high-speed, continuous operation lines). It forms a high-performance film with a uniform thickness, even on the fine uneven shapes and sharp edges of the molds. **Main Improvement Effects from Implementation** - **Advanced Release Properties Under Continuous Heating (Prevention of Film Adhesion)** Cuts down on the adhesion of packaging films (such as PP, PE, and composite laminates) to the molds and the sticking of resin debris at high temperatures. This suppresses defects in the appearance of the sealing surface and biting, supporting stable continuous operation. - **High Durability Against Severe Pressure Friction** Solves the common issues of "early wear and peeling" seen with conventional fluororesin coatings through our proprietary film design. It maintains coating strength even under high-pressure and high-frequency sealing environments, prolonging the initial release performance. - **Extended Maintenance Cycles and Cost Reduction** Significantly reduces downtime associated with the removal of burnt resin debris and mold replacement, contributing to increased productivity.
basic information
【Construction Technology】 High Durability Fluororesin Coating "Thermo Pro Release" 【Technical Features and Functions】 ■ High Non-Stick and Thermal Release Properties Prevents melting and adhesion of plastic films and laminate materials during high-temperature heating. ■ Pressure Resistance and Wear Resistance A robust structure that is less prone to film wear and peeling even in harsh sealing environments subjected to heat, pressure, and repeated contact. ■ Uniform Application to Edges and Fine Shapes Precise coating with uniform film thickness even on the lattice and serrated shapes (laser part) of the sealing bar and edge areas. ■ Safety and Hygiene Compliance Can be safely introduced into manufacturing lines for food and pharmaceutical packaging. 【Target Substrates and Applicable Parts】 ■ Heat sealing bars, welding receiving molds, crimpers, heat sealers, integrated cutting blade sealing jigs. ■ Various metal parts including steel, stainless steel (SUS), aluminum, copper, and brass.

Applications/Examples of results
**Main Application Areas - Packaging Line** ■ Food and Confectionery Packaging Three-side seal bags, pillow packaging machines, cup sealers, tray sealers ■ Pharmaceuticals and Medical Devices PTP packaging, sterilization bags, heat seal and welding parts for medical materials ■ Daily Goods and Cosmetics Pouch containers, sachet bags, sealing processes for refillable film containers **Case Study on Problem Solving** ■ Issue In the heat sealing process of automatic packaging machines, resin films were sticking to the high-temperature sealing bars, causing welding defects and surface scratches. The conventional fluoropolymer coating wore off quickly due to heating and pressure friction, requiring operators to frequently stop the machine for cleaning burnt residues and changing molds, leading to decreased productivity. ■ After Implementation "Thermo Pro Release" was applied to the contact surfaces of the sealing bars and receiving molds. ■ Effects and Results - Film sticking and scorching issues were resolved, maintaining a clean and reliable sealing surface. - The wear resistance of the coating significantly improved, drastically reducing the effort required for mold cleaning and downtime of the production line.

Nikken Coating Industry Co., Ltd. has been a specialized manufacturer of functional coatings for contract processing, earning the trust of customers across various industries for 79 years since its founding. We leverage our processing technology to maximize the properties of fluororesins, such as non-stick, lubricity, and chemical resistance, providing high-performance coatings that directly address customer challenges, including "Thermo Pro Release" for thermal welding processes and "NonStick STC" for blades and precision molds. In recent years, in response to movements regarding regulations on fluorinated compounds (PFAS), "PEEK resin," which is gaining attention as a substitute for fluororesins, has become a focus. Nikken Coating Industry commercialized the world's first PEEK resin coating, "PEEKCOAT," in 1999. Based on the solid knowledge and know-how accumulated over more than 20 years, we are further intensifying our research and development efforts to explore the potential of next-generation PEEK coatings! We aim to be recognized as "the go-to for PEEK coatings" and will continue to lead the way. As "the best partner for functional coatings that builds trust through technology," Nikken Coating Industry will continue to contribute to the creation of high-quality, high-performance products.
