The commonly used oil-resistant agents for pulp molding are fluorine-free oil-resistant agents, fluorine-containing oil-resistant agents, and barrier coatings. Each type has its unique characteristics and advantages, catering to different market needs and application scenarios. Fluorine-free oil-resistant agents are increasingly favored by companies for their environmental friendliness and safety. Fluorine-containing oil-resistant agents, due to their strong oil-resistant properties, are widely used in high-end markets. Barrier coatings, on the other hand, provide multiple layers of protection and are suitable for high-demand packaging fields. Choosing the right oil-resistant product can effectively improve packaging quality and meet consumers’ requirements for food packaging hygiene, environmental protection, and protective performance.
