Science and Application of Food Packaging Paper
In the vast arena of the modern food industry, packaging is not only an obscure background role, it bears the important task of protecting food from external contamination, but also an indispensable part of the marketing strategy. In particular, food wrapping paper, a material in direct contact with food, has become the focus of public attention for its safety, functionality and environmental friendliness.
In this paper, we will take an in-depth look at several common food wrapping papers, including grease-proof paper, paraffin paper, silicone paper, sulfuric acid paper, and other common PE laminating papers, and analyze in detail their temperature resistance, production processes, characteristics, and common scenarios.
To summarize, different types of food wrapping paper each have their own unique production processes and usage scenarios. Choosing the right wrapping paper can not only ensure the safety and hygiene of food, but also enhance the market competitiveness of the product. With the increase in consumer awareness of food safety and environmental protection, the future development of food packaging paper will pay more attention to the sustainability and functionality of the material, opening a new chapter in food packaging.
