1. What is food packaging materials?

Food packaging materials, also known as food contact materials, refer to various materials and products that may come into contact with food or food additives (referred to as food below), or whose components may transfer to food under normal use conditions. This includes packaging materials, containers, tools, and equipment used for food production, processing, packaging, transportation, storage, sales, and use, as well as inks, adhesives, lubricants, and other materials that may directly or indirectly contact food.

Composite materials and their products are two or more layers of food contact materials and products that are composed of different or the same materials bonded, thermally fused, or otherwise combined.

Composite materials and products are food contact materials and products that are assembled, welded, inlaid, or otherwise combined by two or more different or the same materials.

Food packaging materials are like the second skin of food. They can effectively prevent food from being affected by external adverse factors such as microbial corrosion, chemical pollution, oxidation, etc., ensuring the quality and safety of food during storage and transportation. Testing of packaging materials is also very important. They can also extend the shelf life of food to a certain extent and promote the product itself with their exquisite appearance.

2. What principles should we follow when choosing food packaging materials?

Food packaging materials play a crucial role in ensuring the quality and safety of food during storage, transportation, and sales. Therefore, it is essential to choose suitable packaging materials that meet the technical requirements for packaging, including packaging strength, barrier properties, heat resistance, and light avoidance.

There are several principles that food packaging materials need to follow to ensure the quality and safety of food. Firstly, the corresponding principle should be followed, which means that different grades of food require corresponding packaging materials. Secondly, the applicability principle should be followed, which means that different types of food require different packaging materials that can protect them during different stages of circulation.

For example, puffed food requires high sealing packaging materials, while poultry and egg products require shock-resistant packaging materials to prevent breakage during transportation. High-temperature food requires heat-resistant packaging materials, while low-temperature refrigerated food requires low-temperature-resistant packaging materials.

In addition to considering the characteristics of food, the selection of packaging materials should also take into account climate conditions, transfer methods, circulation, and different market demands. The economic principle should also be considered when selecting packaging materials, as the cost of packaging materials is related to market procurement costs, processing costs, and circulation costs.

Furthermore, the aesthetic principle should also be considered when selecting packaging materials. Attractive food packaging can increase product sales. Therefore, the design of food packaging using suitable materials should consider factors such as texture, transparency, stiffness, and smoothness.

Finally, the scientific principle should also be considered when selecting packaging materials. This means that the choice of packaging materials should be based on market demand, function, and consumer preferences. For example, environmentally friendly packaging materials should be used for products that require high environmental protection standards.

Selecting suitable food packaging materials is essential for ensuring the quality and safety of food products. Therefore, it is necessary to follow the above principles when selecting packaging materials for different types of food products.
