How to apply high barrier packaging film technology in food packaging 2

Applications of High-Barrier Packaging Film Technology in Different Food Packaging

Meat Product Packaging

Meat products are susceptible to erosion by oxygen and microorganisms, leading to spoilage and decay. High-barrier packaging films can effectively block oxygen, inhibit microbial growth and reproduction, and extend the shelf life of meat products. For example, meat products packaged with PVDC-coated films can have their shelf life extended to several months or even longer. Additionally, some high-barrier films have good heat resistance and puncture resistance, enabling them to withstand pressure and impact during meat processing and transportation.

Dairy Product Packaging

Dairy products are highly sensitive to oxygen and water vapor, making them prone to oxidation and spoilage. High-barrier packaging films can effectively prevent the entry of oxygen and water vapor, maintaining the freshness and taste of dairy products. For example, EVOH multi-layer co-extruded films are commonly used for dairy product packaging due to their high transparency and good barrier properties, meeting consumer demands for both aesthetics and freshness in dairy packaging.

Baked Goods Packaging

Baked goods such as bread and cakes easily absorb moisture from the air, leading to softening and spoilage. High-barrier packaging films can effectively block water vapor, maintaining the crisp texture of baked goods. For example, bread packaged with metallized films can have its shelf life extended to several days or even longer. Additionally, some high-barrier films have good breathability, allowing baked goods to maintain a certain humidity inside the packaging, preventing excessive drying.

Nut Product Packaging

Nut products are rich in oils and fats, making them prone to oxidative spoilage. High-barrier packaging films can effectively block oxygen, preventing the oxidation of nut products. For example, nuts packaged with PVDC-coated films can have their shelf life extended to several months or even longer. Additionally, some high-barrier films have good moisture-proof properties, preventing nut products from absorbing moisture from the air and maintaining their taste and quality.

Fruit and Vegetable Packaging

Fruits and vegetables are susceptible to erosion by oxygen and microorganisms during storage and transportation, leading to spoilage and decay. High-barrier packaging films can effectively block oxygen and microorganisms, extending the shelf life of fruits and vegetables. For example, fruits and vegetables packaged with modified atmosphere packaging films can have their shelf life extended to several weeks or even longer. Additionally, some high-barrier films have good breathability, allowing fruits and vegetables to maintain a certain humidity and carbon dioxide concentration inside the packaging, promoting respiration and extending their freshness period.

Development Directions of High-Barrier Packaging Film Technology

Environmental Sustainability

With increasing awareness of environmental protection, high-barrier packaging film technology will develop towards environmental sustainability. For example, developing biodegradable high-barrier packaging film materials, such as bio-based polymers and starch-based polymers, can meet the barrier performance requirements of food packaging while reducing environmental pollution.

High Performance

To meet the higher demands of the food industry for packaging performance, high-barrier packaging film technology will develop towards high performance. For example, by improving material formulations and production processes, further enhancing the barrier properties, mechanical properties, and heat resistance of films; developing multifunctional high-barrier packaging films, such as films with antibacterial, antioxidant, and intelligent monitoring functions, to provide more comprehensive protection for food.

Personalized Customization

Different foods have varying packaging requirements, and consumer demands for packaging are increasingly diverse. Therefore, high-barrier packaging film technology will develop towards personalized customization. For example, providing customized film products based on the characteristics of different foods, packaging forms, and consumer needs, such as films with different colors, patterns, transparency levels, and barrier properties.
