Follow the manufacturer to understand the food packaging base paper

Food packaging base paper is pulp and cardboard as the main raw materials, after a series of processing, used for packaging food special paper. Because of its direct contact with food, this paper must meet strict hygiene and safety requirements. The following is a detailed analysis of food packaging base paper:

Definition and classification

Definition: Food packaging base paper is pulp or cardboard as a base material, processed through a specific production process, used for packaging food paper.

Classification: According to the different uses, food packaging base paper can be divided into non-container food packaging base paper and container food packaging base paper two categories. Non-container food packaging base paper includes food aluminum foil lining paper, oil-proof base paper, waxed base paper, coated or coated base paper, food grade kraft paper and other categories; Container food packaging base paper includes paper cups, paper bowls and liquid wrappers such as milk cartons.

Second, performance requirements

Hygiene: All materials and products that come into contact with food must be tested to confirm that the product has met the requirements of food grade safety. These tests include physical tests (such as density, tensile strength, etc.), chemical tests (such as migration tests, heavy metal content tests, etc.), and biological tests (such as various microbial tests, etc.).

Function: According to the specific requirements of use, food packaging base paper also needs to have moisture-proof, oil-resistant, low-temperature freezing resistance, fresh-keeping quality assurance and other functions. For example, oil-proof base paper can effectively prevent oil penetration and keep food dry and clean; Waxed base paper can increase the gloss and water resistance of the paper.

Environmental protection: Food packaging base paper should have good degradability and recyclability to reduce environmental pollution. For example, food grade kraft paper is a biodegradable food packaging material, which can be used as a fertilizer after degradation and does not release harmful substances to the environment.

3. Production process

The production process of food packaging base paper usually includes paper preparation, printing processing, coating processing, die-cutting processing and packaging finishing steps. Paper preparation is the first step in the entire production process, usually using pulp as a raw material. After the pulp preparation is completed, it is necessary to go through the molding, pressing, drying and other processes of the paper machine to convert the pulp into paper. In the printing processing stage, the paper will be printed on the corresponding pattern and text, in order to increase the beauty of the wrapping paper and marketing effect. Coating processing is to enhance the functional properties of the wrapping paper, such as moisture resistance, water resistance, oil resistance and so on. Through die-cutting processing and packaging finishing and other steps, the paper is processed into the shape and size that meet the packaging requirements, and the finishing and packaging treatment is carried out.

Fourth, market prospects

With the increasing global concern for food safety and environmental protection, the market prospect of food packaging base paper is very broad. On the one hand, paper packaging is favored by more and more consumers because of its degradability and environmental protection; On the other hand, with the rapid development of the food industry and the continuous improvement of consumer requirements for food packaging, the demand for food packaging base paper is also increasing. Especially in emerging markets such as China, with the improvement of residents' income level and the change of consumption habits, the market potential of food packaging base paper is huge.

5. Precautions

When purchasing food packaging base paper, consumers should carefully check the production date, shelf life, manufacturer and other information of the product, and pay attention to observe whether the packaging paper has blurred printing, easy to decolorization or pungent odor. At the same time, should try to avoid the use of white too high wrapping paper, because this kind of wrapping paper may add fluorescent whitening agents, harmful to the human body.

Storage and use: Food packaging base paper should pay attention to moisture, sun protection and pollution prevention during storage and use. At the same time, direct contact with sharp objects should be avoided during use, so as not to scratch the paper and affect the use effect.

In summary, food packaging base paper is a kind of special paper with strict health and safety requirements, and its performance requirements, production process and market prospects have significant characteristics and advantages. In the future development, with the increasing attention of consumers to food safety and environmental protection issues, the market prospect of food packaging base paper will be broader.
