[Case Study] Coating to Improve Release Properties of Film Welding Heat Plates

[Food Industry] Improved non-stick properties of welded plates with reduced contact area fluoropolymer coating! Measures to prevent adhesion of films that stick even with fluoropolymer coatings.

We would like to introduce a case where we solved the sticking trouble of the melt film that could not be resolved with fluororesin coating. ■ Background of the Consultation The consultation was regarding a tray sealer that covers plastic trays with film. In the thermal fusion process of sealing film onto plastic containers, the heating plate is heated to over 100°C, causing the surface of the film to melt. Initially, the heating plate was coated with fluororesin to prevent the film from sticking. ■ Background of Coating Selection The material of the film and the temperature at which it melts were causing product defects due to sticking to the heating plate. Additionally, small holes were drilled in the heating plate for vacuuming the film, which limited the options for coating. ■ Coating Adopted "TP Coating" ■ Adoption Background and Effects To accommodate many conditions, we proposed a release-type coating that excels in release properties compared to the current coating and does not hinder vacuuming, while also reducing contact area. The "TP Coating," which has good release properties and does not affect vacuuming, was adopted. *For more details, please refer to the materials or contact us directly.
