In the circulation and consumption chain of agricultural products, shelf life is the gold standard for measuring their quality and freshness. It not only concerns the nutritional value and taste experience of agricultural products, but also directly affects the economic benefits of agricultural producers and consumers' willingness to buy. However, agricultural products often face a series of challenges such as oxidation, deterioration, and loss during long-distance transportation and long-term storage. So, how to effectively extend the shelf life of agricultural products and ensure that they can maintain their best condition in all circulation links? Aluminum-coated CPP (Cast Polypropylene) film, as an advanced packaging material, is becoming the "time guardian" for agricultural product preservation with its excellent gas barrier properties.
Urgent need for agricultural product preservation
Agricultural products, especially fresh foods such as fruits, vegetables, and meat, have extremely high requirements for storage and transportation conditions due to their perishable and perishable characteristics. Once the environmental conditions are not suitable, agricultural products will oxidize rapidly, resulting in nutrient loss, taste loss, and even the growth of harmful microorganisms, causing food safety problems. Especially in the process of long-distance transportation and long-term storage, the preservation challenges faced by agricultural products are even more severe. Therefore, finding a packaging material that can effectively slow down the oxidation process of agricultural products and extend the shelf life has become an urgent problem to be solved in the agricultural field.
Aluminum-coated CPP film, as an innovative packaging solution, provides strong support for the preservation of agricultural products through its excellent gas barrier properties. The film forms a dense barrier layer by coating a thin layer of aluminum atoms on the surface of high-quality cast CPP film. This aluminum layer not only gives the film a metallic luster, but more importantly, it significantly improves the film's barrier ability to gases such as oxygen and carbon dioxide.
Oxygen is one of the main culprits that cause agricultural product oxidation. When agricultural products are exposed to the air, oxygen reacts with its internal enzymes, fats, vitamins, etc., resulting in the loss of nutrients, poor taste, and darker color of agricultural products. The oxygen barrier property of the aluminized CPP film is like a solid barrier that effectively prevents the intrusion of oxygen, thereby slowing down the oxidation process of agricultural products.
The barrier property of aluminized CPP film to carbon dioxide is also extremely excellent. During the storage and transportation of agricultural products, the accumulation of carbon dioxide often leads to the acidification of the internal environment of agricultural products, affecting their quality. Aluminum-coated CPP film can effectively control the permeability of carbon dioxide, maintain the relative stability of the internal environment of agricultural products, and further extend their shelf life.
The gas barrier property of aluminized CPP film not only provides a strong guarantee for the preservation of agricultural products, but also plays a huge role in long-distance transportation and long-term storage of agricultural products. During long-distance transportation, agricultural products often need to experience long-term bumps and vibrations, and also face complex and changeable climatic conditions. These factors will accelerate the oxidation process of agricultural products and shorten their shelf life. The application of aluminized CPP film is like putting on a layer of "protective clothing" for agricultural products, which effectively slows down their oxidation rate and extends the shelf life, so that agricultural products remain in the best condition when they arrive at their destination.
In terms of long-term storage, aluminized CPP film also shows its unique advantages. By controlling the permeability of oxygen and carbon dioxide, aluminized CPP film can maintain the relative stability of the internal environment of agricultural products, reduce the growth and reproduction of microorganisms, and thus extend the storage period of agricultural products. For agricultural product producers, this means higher economic benefits and more stable sales channels; for consumers, it means that they can enjoy the freshest and highest quality agricultural products when purchasing.
The application of aluminized CPP film not only extends the shelf life of agricultural products, but also plays an important role in reducing the loss of agricultural products during transportation and storage. Traditional packaging materials often cannot effectively prevent the intrusion of oxygen and the accumulation of carbon dioxide, which leads to rapid oxidation and deterioration of agricultural products during storage and transportation, resulting in a large amount of loss. The aluminized CPP film effectively reduces the loss rate of agricultural products and improves the utilization rate and value of agricultural products through its excellent gas barrier properties.
Aluminized CPP film also has good transparency and glossiness, which can clearly show the appearance and quality of agricultural products and enhance the market appeal of agricultural products. This is undoubtedly a huge plus for the sales and promotion of agricultural products.
While pursuing the preservation and quality of agricultural products, we must also pay attention to the environmental protection and sustainability of packaging materials. As an advanced packaging material, aluminized CPP film not only has excellent gas barrier properties, but also shows its unique advantages in environmental protection and sustainability. The film can be recycled and reused, reducing environmental pollution and waste of resources. With the advancement of technology and continuous optimization of production processes, the environmental performance and sustainability of aluminum-coated CPP film will be further improved.
