The quality and functionality of the materials used for food packaging have become an issue that cannot be overlooked in the food sector as people continue to pay attention to the safety of food. Extensive research and developments have been carried out by scientists in order to enhance the performance of food packaging materials and to make them more in line with the rules that govern food safety. The research that has been done on the functional modification of food packaging materials will be discussed in this article, along with some examples of successful modifications.

The need for materials that have been functionally changed

Packaging materials for food are an extremely important factor in ensuring the safety of food. Plastic film and paper are examples of traditional food packaging materials that are not capable of meeting the requirements of some types of special foods. For instance, certain perishable foods require improved preservation characteristics, but foods that contain oxygen require excellent oxygen barrier capabilities. In addition to keeping food fresh for an extended period of time, the materials used for food packaging must also be resistant to pressure, heat, and chemicals. In light of this, there is an immediate demand for materials that have been functionally changed.

Techniques for the adaptation of functionality

1. Modification through absorption

In order to modify the functional properties of materials, additives are an important means of doing so. There is potential for the performance of food packaging materials to be improved with the use of additives in the appropriate proportions. Antibacterial agents, for instance, can be added to food in order to lengthen its shelf life, and antioxidants can be added in order to prevent food from deteriorating due to oxidative stress. In addition, additives have the ability to alter the physical qualities of the materials used for food packaging. A few examples of these changes include increasing the materials’ toughness and transparency.

2. Compound modification

The process of combining two or more materials that have distinct characteristics in a certain ratio in order to create a composite material that may perform a variety of functions is referred to as composite modification. To provide one example, the combination of plastic films that have strong oxygen barrier capabilities and materials that are degradable not only ensures that food is fresh, but it also decreases the amount of strain that is placed on the environment. The modification of composite materials enables food packaging materials to have a greater number of functions and to cater to the requirements of a variety of foods.

Utilisation of materials that have been functionally changed

1. Materials that are resistant to ultraviolet light

The presence of ultraviolet rays can have a negative impact on food, causing it to lose its flavour and nutritional content, and even contributing to the spoilage of food. As a result, researchers came up with a material for packaging that is both functional and capable of successfully isolating ultraviolet light. Because of its unique composition, this material is able to withstand the deterioration caused by ultraviolet rays to the greatest extent possible without compromising the quality of the food contained within it.

2. Materials for packaging that are antibacterial

Concerns about the safety of food are shared by all. It is of utmost significance to do research on antibacterial packaging materials in the realm of food packaging. The development of an antibacterial packing material that can prevent the growth of bacteria in food has been accomplished by members of the scientific community. Antibacterial agents can be added to the substance, which has the potential to successfully increase the shelf life of food and improve the safety of food.

3. Material that has a high oxygen barrier

When it comes to goods that contain oxygen and need to be sealed and kept, it is absolutely vital to investigate different types of packing materials that have a high oxygen barrier. Materials with a high oxygen barrier have the ability to efficiently prevent oxygen from entering the interior of food packaging, hence lowering the risk of oxidation processes and lowering the likelihood of food deterioration. This functionally modified material has a wide range of uses, including packaging for fresh food, packaging for coffee powder, and other sectors.
application prospects.

Applications of functionally changed materials in the future

Functional modified materials provide the food packaging sector with a greater variety of options and opportunities for innovation. The growth of technology will continue to progress, which will result in functional changed materials becoming more diverse and efficient. In addition, the needs that people have for the convenience and safety of their food will continue to rise, which will encourage scientists to continue their research and development of new functional modified materials.
at the end of day

The importance of doing research on the functional modification of materials used for food packaging cannot be overstated. Increasing the number of activities that packaging materials can do and ensuring the quality and safety of food can be accomplished through the use of techniques such as additive modification and compound modification. The food packaging industry has made extensive use of functionally modified materials, including materials that eliminate ultraviolet light, materials that inhibit the growth of bacteria, and materials that have a strong oxygen barrier. Potential applications of functionally modified materials will become more widespread as technological advancements continue to be made. The provision of people with food packaging materials that are both healthier and safer, as well as the enhancement of food safety, will be significant directions for study in the future. Solutions for the alteration of food films are offered by COACE. Modifiers by Coace have the potential to significantly enhance the performance of food packaging materials, such as oxygen barrier qualities, and to better extend the shelf life of food. For example, mixing plastic films that have strong oxygen barrier properties with other materials can be an effective way to do this. The composite material made of degradable materials not only ensures that food stays fresh, but it also lessens the load that is placed on the environment, and it enhances the resistance to pressure, heat, and chemicals, among other functions!
