Stone paper: the dual advantages of waterproof, durable and environmentally friendly degradation

Stone paper stands out in many fields with its unique physical properties. Its waterproof properties are derived from the natural hydrophobicity of the calcium carbonate substrate, which can keep the paper intact even after long-term immersion. This feature makes it perform well in outdoor signs, maps and other scenes. At the same time, the high molecular polymer coating of stone paper gives it excellent tear resistance, and its strength can reach more than 3 times that of traditional paper, which is particularly suitable for making durable packaging and document bags.

In terms of environmental performance, the recycling of stone paper is more efficient. Through special processes, stone paper can be completely recycled and recycled, and the recycling process does not require chemical deinking, which greatly reduces environmental pollution. In the natural environment, stone paper can be photodegraded under sunlight and can be completely decomposed into calcium carbonate powder in 18-24 months without causing soil pollution.

These characteristics make stone paper widely used in outdoor advertising, nautical maps, waterproof labels and other fields, and its environmental performance also meets the sustainable development needs of modern society. With the continuous advancement of technology, stone paper will show its unique value in more fields.
