Types and Safety of Food Packaging Materials
There are many types of food packaging materials, which can be roughly divided into several categories based on their material: paper, plastic, metal, glass, and composite materials. Paper packaging is favored for its biodegradable and environmentally friendly characteristics, but the chemical substances that may be added during the production process, such as fluorescent whitening agents and oil and water repellents, must be strictly controlled to prevent excessive residues. Plastic packaging is widely used due to its lightweight, moisture-proof, and excellent gas barrier properties.
The production process and safety control of food packaging
The production process of food packaging includes several stages such as raw material selection, processing and forming, printing and decoration, and post-processing. Each stage may introduce safety hazards. The selection of raw materials must ensure they are non-toxic, harmless, and pollution-free, meeting food-grade standards.
