The appearance of stone paper is gradually being valued at home and abroad. Unlike traditional papermaking, the raw material of stone paper is mainly stone, a small amount of resin, and some additives made by a series of physical methods.
Stone paper has the following characteristics:
- A simple manufacturing method; a significant investment, low energy consumption, and high output.
- By not utilizing fiber from plants or tree felling, forests can be preserved, and natural ecology is protected.
- It does not require adding chemical materials such as strong acid, strong alkali, or bleach. It does not emit wastewater, waste residue, or toxic and harmful gases.
- It has good mechanical properties, is water and moisture-resistant, moth-proof, folding and tear-resistant, odorless, pollution-free, and has stable geometric dimensions. It can also be decomposed to powder and returned to nature after being discarded.
Classification of stone paper (stone paper notepad)
The first category consists of a variety of biodegradable and eco-friendly packaging products.
This product will primarily replace conventional packaging made of plastic. There exist two basic types of industrial packaging materials: inert packaging materials and live packaging materials. Dust coverings and protective covers for electronics, home appliances, and industrial equipment are industrial packaging materials. Living packaging materials include everyday package bags, shopping bags, waste bags, and roll bags.
The second category includes eco-friendly thermoformed stone cardboard goods.
Because of advantages in raw materials, manufacturing technology, and technological processes, thermoformed stone cardboard products are the only boards globally with nearly zero benzene and formaldehyde. The items are free of dangerous chemicals such as heavy metals, have no odor, are resistant to dampness, and have flame retardant and anti-microbial properties. The environmental indicators of its goods have passed the testing and certification of critical national testing bodies, met the testing standards of the European Union, and have made significant advances in health and environmental protection.
The third category includes environmentally friendly stone paper sheet goods.
Its primary application is to replace some traditional use plates, packaging plates, and customized plates. This type of product differs from typical board manufacturing. It does not use wood pulp, does not need the felling of trees, does not emit strong acids, strong alkalis, or other chemical substances, and does not discharge wastewater.
