Oil and Grease Proof Paper

Product Description

1. Material

• Typically made from kraft paper (a durable paper) or bleached paper that has been treated with either a coating or chemical additives to make it resistant to grease and oil.
• It can also be made from cellulose fibers, and may undergo treatments like sizing or coating with substances such as paraffin, wax, or vegetable-based oils to enhance its grease-resistant properties.

2. Properties

• Grease Resistance: The paper is specifically treated to prevent oils or greases from soaking through. It is suitable for foods such as burgers, fried items, pastries, and pizza boxes.
• Oil Resistance: Acts as a barrier against oil penetration and staining.
• Durability: The paper is strong and tear-resistant, designed to hold up even when exposed to oils, hot food, or moisture.
• Breathability: The paper allows for some air circulation, preventing moisture buildup which could cause sogginess in the food.
• Non-toxic and Food Safe: Often used in food packaging, the paper should meet safety standards for food contact (e.g., FDA-approved in the U.S.).

3. Weight and Thickness

• The weight typically ranges from 35-70 g/m (grams per square meter), but this can vary depending on the intended use.
• Thickness can range from 0.05 mm to 0.15 mm, with variations depending on the application.

4. Applications

• Food Packaging: Commonly used in food packaging like sandwich wraps, pizza boxes, fast food wrappers, and bakery products.
• Fast Food Industry: Suitable for wrapping fried foods, burgers, fries, and snacks.
• Takeout and Deli Paper: Often used for take-out containers or in delis for wrapping oily meats or sandwiches.
• Baking: Used as liners for baking trays to prevent sticking and to absorb excess oils and greases from baked goods.

5. Appearance

• The paper typically has a smooth or slightly textured surface, and it can be either natural brown or white, depending on the base material and coating used.
• It can be printed with custom logos or designs if desired for branding purposes.

6. Environmental Considerations

• Some oil and grease proof papers are biodegradable or made from recycled paper, contributing to sustainability goals.
• Although some versions may be treated with chemicals or coatings, there are more eco-friendly options available that are compostable and contain fewer synthetic substances.

7. Performance Characteristics

• Temperature Tolerance: Can generally withstand hot temperatures (up to around 200F or 93C) without degrading.
• Moisture Resistance: The paper is designed to prevent moisture from seeping through, making it ideal for oily, greasy, or wet foods.
