The demand for fresh and high-quality food has increased in recent years. Consumers have become more conscious about the safety and quality of their food. This has led to the development of modified atmosphere packaging (MAP), which involves changing the composition of gases surrounding food to extend shelf life and maintain freshness. One of the essential components of MAP is the high-barrier PET sheet. This article will explore a high-barrier PET sheet, how it works, and its benefits in enhancing MAP performance.

What is High-Barrier PET Sheet?

High-barrier PET sheet is a multi-layer film designed to provide an exceptional barrier against gas and moisture. It is made from a combination of PET (polyethylene terephthalate) and other high-performance materials such as EVOH (ethylene vinyl alcohol) and PA (polyamide). Combining these materials creates a film with superior barrier properties, making it an ideal material for MAP applications.

How does High-Barrier PET Sheet work?

High-barrier PET sheet prevents gas and moisture exchange between the inside and outside of the packaging. It maintains a specific gas mixture suitable for packaged food when used in MAP applications. The high-barrier PET sheet acts as a barrier to oxygen, carbon dioxide, and water vapor, which are the primary causes of spoilage in food. This creates a modified atmosphere inside the package that extends the shelf life of the food.

Benefits of High-Barrier PET Sheet in MAP

Using high-barrier PET sheets in MAP applications provides several benefits, including:

Extended Shelf Life

The primary benefit of a high-barrier PET sheet is that it extends the shelf life of the food. By maintaining a modified atmosphere conducive to the specific food being packaged, a high-barrier PET sheet helps prevent spoilage and degradation. This, in turn, extends the shelf life of the food, allowing it to remain fresh for longer.

Improved Food Safety

High-barrier PET sheet provides an additional layer of protection against contamination. Preventing the exchange of gas and moisture between the inside and outside of the package helps maintain the integrity of the food. This reduces the risk of contamination from outside sources, such as bacteria or other contaminants.

Increased Product Visibility

High-barrier PET sheet is a transparent material that allows consumers to see the product inside the package. This is especially important for food products, as consumers want to know the quality and freshness of purchasing food.

Environmentally Friendly

High-barrier PET sheet is a fully recyclable and sustainable packaging material. This means it can be reused and repurposed, reducing the environmental impact of packaging waste.

Applications of High-Barrier PET Sheet

High-barrier PET sheet is suitable for a wide range of MAP applications, including:

Meat and Poultry Packaging

High-barrier PET sheet is commonly used for packaging meat and poultry products. It helps maintain the freshness and quality of the product, ensuring that it remains safe for consumption.

Fresh Produce Packaging

High-barrier PET sheet is also suitable for packaging fresh produce such as fruits and vegetables. It helps maintain the freshness of the product, reducing spoilage and increasing shelf life.

Snack Food Packaging

High-barrier PET sheet is an ideal material for snack food packaging. It helps maintain the crunchiness and freshness of the snacks, ensuring they remain tasty and appealing to consumers.


High-barrier PET sheet is a versatile packaging material that provides exceptional barrier properties against gas and moisture. It is an essential component of modified atmosphere packaging, which is widely used in the food industry to maintain freshness and extend the shelf life of food. High-barrier PET sheet offers several benefits, including extended shelf life, improved food safety, increased product visibility, and environmental friendliness. It is a sustainable packaging material that is fully recyclable, making it an ideal choice for eco-conscious consumers.

High-barrier PET sheet is suitable for various MAP applications, including meat and poultry packaging, fresh produce packaging, and snack food packaging. Its superior barrier properties make it an excellent choice for any food product that requires extended shelf life and protection against spoilage.

In conclusion, using high-barrier PET sheets in modified atmosphere packaging is a game-changer in the food industry. It helps maintain the freshness and quality of food and reduces food waste and environmental impact. As consumers continue to demand high-quality and safe food products, using high-barrier PET sheets will become even more critical in ensuring food safety and quality.
