Surface treatments for cooking plates, sealing bars and heat sealing tools

Which technical coating should be use to protect heating plate, sealing bars or thermosealing tools?

Sofiplast, a specialist in surface treatment, provides high-performance non-stick and high-temperature-resistant coatings for heating plates, sealing bars, and heat-sealing equipment. These food-contact-compliant solutions facilitate product release, reduce wear, and ensure hygienic, reliable, and long-lasting production in the food-processing industry.

In food-processing cooking and heat-sealing operations, equipment such as heating plates, sealing bars, and heat-sealing systems is exposed to severe adhesion and wear caused by high operating temperatures.

In environments where hygiene, food safety, and equipment durability are critical, Sofiplast offers food-contact-compliant coatings designed to strengthen surface protection, extend equipment lifespan, and reduce production downtime while optimizing maintenance costs.


Technical coatings and non-stick surface solutions for the food-processing industry

Cooking plates used in food production are frequently exposed to adhesion issues, leading to product loss, residue buildup, and inconsistent cooking results. To prevent these problems, non-stick coatings such as:

  • Fluoropolymer coatings (PTFE, Teflon®, Xylan®, or Greblon®)

can be applied to improve product release and ensure uniform cooking performance.

These solutions help reduce material loss, simplify equipment cleaning, and fully comply with food-contact regulations.

Technical coatings and high-temperature-resistant solutions for the food-processing industry

Heating plates and sealing bars are exposed to high operating temperatures that can cause premature wear, surface deformation, and gradual performance loss over time. Applying heat-resistant coatings such as technical ceramics or specialty alloys helps protect surfaces from thermal stress and excessive wear.

These solutions extend equipment lifespan and maintain consistent performance, even under demanding operating conditions.

All treatments carried out by Sofiplast on food-processing equipment use coatings that comply with food-contact regulations. These certifications ensure that surfaces in direct contact with food meet all applicable requirements and remain safe throughout their intended service life. This provides a critical level of assurance for meeting the strict standards of the food industry.

Our eco‑friendly stripping processes adapted to food‑contact standards

o ensure the long-term performance and durability of heating plates, sealing bars, and heat-sealing equipment, Sofiplast applies food-contact-compliant technical coatings designed to reduce adhesion, wear, and thermal deformation at high operating temperatures.

Before applying the coating, we work with you to define the most suitable eco-friendly stripping process. This method uses biodegradable and reusable plant-based media (wheat starch, corn, and fruit shells) as a safer alternative to more aggressive techniques such as sandblasting, laser cleaning, or chemical treatments.

Sol‑Gel: a PFAS‑free ceramic alternative for the food‑processing industry

Sol-gel technology involves applying a thin ceramic coating derived from colloidal solutions which, after curing, form a solid network of metal oxides such as silica. Applied by spraying or dipping, this process creates a uniform and consistent coating. While offering slightly lower non-stick performance than fluoropolymers, sol-gel provides excellent mechanical strength, high-temperature resistance, and low curing temperatures that help reduce energy consumption. Its PFAS-free formulation ensures compliance with European food-contact regulations.

With this solution, Sofiplast anticipates evolving regulatory requirements and supports its customers in adopting surface treatments that combine performance, durability, and sustainability.
