Classification And Application Of Food Cardboard

As a common material in the field of food packaging, food cardboard has many classifications and their respective applications are wide.
First is white cardboard. It is characterized by whiteness, smoothness, good printing performance, and is composed of multiple layers of wood pulp. It is often used in high-end food packaging, such as chocolate, hardcover candy, etc., and can show product characteristics through exquisite printing to attract consumers.
The second is food packaging paper. This is a kind of paper that can be directly packaged for imported food without waxing. It is divided into many types. The raw material is natural chemical straw pulp or semi-chemical straw pulp. It is made by a round net single (multi) cylinder papermaking machine. It should meet relevant hygiene indicators and do not use harmful additives. It is an important choice for various solid food packaging, such as biscuits, cakes, etc., which protects food while giving people a clean and hygienic feeling.
There is also paper bag paper. Paper bag paper is divided into No. 1, No. 2, No. 3, No. 4, etc., which is used to make paper bags. For example, the packaging of products such as cement and fertilizer requires high-strength paper bag paper to ensure that it will not be damaged during bagging and transportation. It is also used in food packaging. Through reasonable design and materials, it can facilitate consumers to carry and preserve food.
In addition, cellophane is also used for food packaging. Cellophane is transparent, moisture-proof, and has good oxygen isolation properties. It is made of cotton pulp and wood pulp. It is suitable for packaging cakes, fruits and other foods. Consumers can directly see the appearance of the food. It is used more on some foods that require transparent packaging display.
