Development Of Paper Food Packaging Materials

Development of paper food packaging materials

Today, green consumption is gradually approaching people's daily life. There are more and more green foods on the market, including grains, vegetables, fruits, milk, drinks, etc. Food paper packaging must strictly abide by green packaging standards. There are many phenomenon of paper packaging in green food. A large amount of white paper is used for food packaging. Most white paper is treated with fluorescent whitening agent. Although it can bleach fiber, it has a great toxic effect on the human body. Many green foods are packed in color packaging paper. Although the color ink is printed on the side and outside of the food packaging paper, the printed color paper is bundled and stacked together. The non -printing surface of each packaging paper will contact the ink, which can easily cause food pollution.

Although my country has regulations on the raw materials and sanitary indicators of food packaging paper, there are no cardboard varieties specifically used for food packaging. A variety of food boxes use gray backboard paper. However, in actual production and post -processing, paper packaging materials will be processed according to product packaging design. During the processing process, it may be added with potential dangerous chemicals such as whipped agent, curing agent and sterilizer. In the middle, it will pose a threat to personal health. Therefore, it is necessary to establish a simple, accurate, and fast analysis detection method to ensure the safety of packaging materials.

The chemical composition of paper packaging materials is complicated, but the relative content is low, so conventional chemical analysis and determination are more difficult. At present, instrument analysis and detection of chemicals in paper packaging materials are mainly used. The commonly used detection techniques include gas chromatography and liquid chromatography. Absorbing spectral method, inductive coupling plasma atom of the atom of the body is often used to detect trace element mercury, pick, lead, chromium, etc.
