The difference between leak-proof paper and baking paper

1. Leak-proof paper
1. Material
Leak-proof paper is mostly made of pulp, membrane material or film-forming material, and can be divided into kraft paper, PVC leak-proof paper and PE leak-proof paper. Commonly used kraft paper is made of wood pulp, which is characterized by toughness, not easy to break, and high quality stability.
2. Structure
Leak-proof paper usually adopts a single-layer or multi-layer composite structure design, which can effectively prevent the leakage of fresh or mucous food. The single-layer leak-proof paper is mainly made of environmentally friendly pulp material and has a simpler structure; while the multi-layer composite structure is composed of a variety of different materials of paper, which can better meet the requirements of food packaging.
3. Function
Leak-proof paper is mainly used for food packaging, especially for liquid and semi-liquid food packaging, and has the functions of anti-leakage, moisture-proof, and anti-oil.
2. Baking paper
1. Material
Baking paper is also called "oil paper" or "wax paper", which is made of paper and grease or silicone grease. Common baking paper materials include silicon paper and paper cups.
2. Structure
Baking paper has a simple structure, with silicon-coated paper as the main structure. Silicone coating can enhance the water resistance and temperature resistance of the paper surface, and form a protective film on the surface of the baking tray to prevent food from sticking to the baking tray.
3. Function
Baking paper is mainly used for baked foods, such as cakes, bread, etc., and has anti-stick and anti-oil functions. In addition, baking paper can simplify the tableware cleaning process and improve the overall quality and appearance of baked foods.
In summary, although leak-proof paper and baking paper are both professional papers, there are obvious differences in material, structure and function. Leak-proof paper is mainly used for food packaging, which can prevent leakage, moisture, and oil; while baking paper is mainly used for the protection of baking trays, which can prevent food from sticking to the baking tray and improve the overall quality and appearance of baked foods. In actual use, appropriate professional paper should be selected according to the specific situation to ensure the safety and quality of food.
