This paper is treated with a special coating and meets two key requirements:
Self-sealing: The paper seals to itself with heat or pressure, making adhesives unnecessary.
Barrier and fat resistance: The coating acts as a barrier against moisture, oxygen, and fat. This prevents the transfer of smells and liquids.
Key features
- Coating materials: The most common materials include solid aqueous copolymer ethylene dispersions and water-based styrene butadiene dispersions with added pigments. These offer good adhesion, a strong seal, and fat resistance.
- Applications: Ideal for packaging foods, especially fatty foods.
Benefits
- Convenience: Eliminates the need to purchase and apply additional adhesives.
- Sustainability: The paper is by definition environmentally friendly.
- Protection: The coating keeps foods fresh and prevents the transfer of fat.
Other important points
- The specific properties of each paper vary depending on the coating used, which determines its degree of resistance to fat.
- It is important to make sure that the coating is safe for use with foods for human consumption.
