Why stone paper can be used as cold food packaging？

Stone paper, also known as mineral paper, is a type of paper made from calcium carbonate (limestone) mixed with a small amount of resin (HDPE – high-density polyethylene). This unique composition gives stone paper several advantageous properties that make it suitable for cold food packaging:

Waterproof: Stone paper is naturally resistant to water and moisture due to its mineral composition. This makes it ideal for packaging cold foods, as it won’t absorb liquids or become soggy.

Grease-resistant: Similar to its waterproof properties, stone paper is also resistant to grease and oil. This feature ensures that the packaging remains intact and clean even when containing oily or greasy cold foods.

Freezer safe: Stone paper can withstand low temperatures without becoming brittle or losing its structural integrity. This makes it suitable for packaging cold foods that require refrigeration or freezing.

Durable: Despite being lightweight, stone paper is surprisingly durable and tear-resistant. It can withstand handling and transportation without easily ripping or tearing, ensuring the contents remain secure.

Eco-friendly: Stone paper is considered more environmentally friendly than traditional paper made from wood pulp because it doesn’t require water or bleach in its production process. Additionally, it can be recycled with plastic materials, reducing the overall environmental impact.

Overall, the combination of its waterproof, grease-resistant, freezer-safe, and durable properties makes stone paper a practical choice for packaging cold foods.
