Glassine paper is a smooth and glossy paper that is air, water, and grease resistant. It is translucent and typically manufactured by supercalendering, a process that gives the paper a high-gloss finish.

Glassine paper is commonly used in various applications such as:

1. Packaging: It is often used as inner liners for envelopes, as well as for packaging delicate items like stamps, photographs, and food products.

2. Crafts: Due to its smooth surface and translucency, glassine paper is popular in crafts such as scrapbooking, card making, and origami.

3. Baking and Candy Making: It is used in baking as a non-stick surface for delicate baked goods and in candy making to wrap individual candies.

The characteristics of glassine paper make it ideal for protecting items that need to be shielded from moisture, oil, or grease.
