GREASE PROOF PAPER

Definition and Classification of Grease Proof Paper:

Food-grade grease proof paper is a specialized material designed for food packaging to prevent oil and grease penetration, and it must comply with food safety standards.

There are two main manufacturing processes:

 
1. Mechanical Treatment: Fibers are densely packed through mechanical processing to reduce porosity, providing natural grease resistance.

 
2. Coating with Food-Grade Materials: Food-grade coatings such as silicone oil or casein are applied to enhance grease resistance. Example: Silicone oil paper.
 

Key Features of Grease Proof Paper:

1.  Contains no toxic substances, making it safe for direct food contact.
 
2. Meets strict safety standards for materials that come into contact with food.
 
3.  Effectively blocks oil and grease absorption or penetration over time.
 
4. Waterproof, oil-proof, and non-stick, ideal for keeping greasy foods contained.
 
5. Works in high heat, freezers, and humid environments without breaking down.
 
6.  Lightweight yet high-strength

Introduction to Grease Proof Paper Grades:

Grease proof paper is classified based on its oil resistance performance and testing standards. Different grades correspond to varying levels of grease barrier capability and specific application scenarios.
