1. nonstick nature
There are many types of stripping agents, and generally speaking, substances with relatively low surface tension have certain stripping performance. The best stripping agent is organic fluorine compounds.
2. Baking paper base paper and requirements
The main substrates that can be used for producing baking paper are three types of special paper, namely parchment paper, semi transparent paper, and high tightness, high smoothness, and ultra pressure sulfate pulp paper. The quality requirements include: ① high physical strength that can withstand high temperature drying; ② Good dimensional stability to avoid problems such as expansion and contraction deformation during post processing; ③ Uniform and consistent thickness; ④ High smoothness ensures continuity, flatness, and uniformity of coating; ⑤ Small surface absorption reduces the consumption of stripping agent; ⑥ Good chemical compatibility, avoiding interference from some chemicals on the stripping agent.
3. Oil resistance
Baking paper needs to be in long-term contact with oily substances during application, so it should avoid oil from penetrating from the contact surface with ingredients to the contact surface with hands, which means it has oil resistance. At present, the oil resistance of paper materials both domestically and internationally is directly obtained through paper-making processing technology, and coated paper has gradually been forced to withdraw from the sales market
