Exploring the Use of Fischer Tropsch Wax as a Barrier Coating in Food Packaging


Understanding the importance of food safety and preservation, researchers and industry professionals have been continuously searching for innovative solutions to enhance food packaging materials. In recent years, Fischer Tropsch wax has emerged as a promising barrier coating material due to its unique properties and potential benefits in food packaging applications. This article aims to explore the various aspects of using Fischer Tropsch wax as a barrier coating and its implications in enhancing food packaging.

I. Understanding Fischer Tropsch Wax

Fischer Tropsch wax is a synthetic hydrocarbon wax that is produced through the Fischer Tropsch process, a chemical reaction that converts carbon monoxide and hydrogen into hydrocarbons. This wax has a high melting point and exhibits excellent moisture resistance and gas barrier properties, making it an ideal candidate for food packaging applications where moisture and gas transmission need to be controlled.

II. Benefits of Fischer Tropsch Wax as a Barrier Coating

1. Enhanced Moisture Barrier Properties

One of the key advantages of utilizing Fischer Tropsch wax as a barrier coating in food packaging is its exceptional moisture resistance. By forming a thin, impermeable layer on the packaging material, it prevents the migration of moisture from the environment, thus safeguarding the food product from spoilage and degradation caused by moisture absorption.

2. Improved Gas Barrier Performance

In addition to moisture resistance, Fischer Tropsch wax also offers remarkable gas barrier properties. It can effectively minimize the permeation of oxygen, carbon dioxide, and other gases, reducing the risk of oxidative reactions and preserving the freshness of the packaged food items. This enhanced gas barrier performance extends the shelf life of perishable food products, reduces food waste, and ensures that consumers receive high-quality goods.

3. Sustainable and Renewable Solution

Fischer Tropsch wax is derived from carbon monoxide and hydrogen, making it a sustainable and renewable resource. Unlike petroleum-based waxes, its production does not rely on fossil fuels. As the world seeks more sustainable alternatives, Fischer Tropsch wax provides an eco-friendly solution in food packaging, reducing the overall environmental impact.

III. Potential Applications of Fischer Tropsch Wax Barrier Coating

1. Snack Food Packaging

Snack foods, such as potato chips and pretzels, are notorious for losing their crunchiness and becoming stale when exposed to air. By applying Fischer Tropsch wax as a barrier coating on snack food packaging materials, manufacturers can effectively restrict moisture and gas transmission, keeping the snacks crisp and maintaining their quality for an extended period.

2. Dairy Product Packaging

Dairy products, including cheese and butter, are highly sensitive to moisture and oxygen exposure. The usage of Fischer Tropsch wax as a barrier coating in dairy product packaging helps to create an optimal environment by preventing the entry of moisture and gases that can accelerate spoilage. This ensures that the products retain their freshness, flavor, and texture for a much longer duration.

3. Confectionery Packaging

Chocolates, candies, and other confectioneries require protection from humidity, oxygen, and light to maintain their taste and appearance. Fischer Tropsch wax barrier coatings can act as a shield, preventing moisture absorption and oxidative reactions, while also reducing the risk of color fading caused by light exposure. Such coatings enhance the overall quality and appearance of confectionery products, ultimately leading to increased customer satisfaction.

4. Fresh Produce Packaging

Fresh fruits and vegetables are highly perishable due to their high moisture content and sensitivity to ethylene gas. Fischer Tropsch wax as a barrier coating in fresh produce packaging acts as a barrier against moisture and ethylene transmission, keeping the produce fresh and crisp for an extended period. This can aid in reducing food waste and ensuring that consumers receive high-quality, nutritious fruits and vegetables.

5. Ready-to-Eat Meal Packaging

Ready-to-eat meals have gained immense popularity in recent times due to their convenience and time efficiency. Fischer Tropsch wax barrier coatings can be applied to the packaging of such meals, helping to maintain their texture, taste, and nutritional value. By minimizing moisture ingress and preventing gas exchange, the shelf life and quality of ready-to-eat meals can be significantly improved, meeting consumer expectations.


The utilization of Fischer Tropsch wax as a barrier coating in food packaging brings numerous advantages, enhancing the preservation and quality of food products. Its superior moisture and gas barrier properties make it an attractive alternative to conventional packaging materials. With its sustainable nature and versatile applications, Fischer Tropsch wax is paving the way for more efficient and environmentally friendly food packaging solutions.
