Titanium dioxide can play the following roles in functional nano-paperboard:

Antibacterial, deodorant

In the production of natural pulp, sterile gas is injected. This paper has the function of preventing the intrusion of bacteria and can be used for the packaging of medical instruments. The newly developed nano-composite functional paper can effectively solve the problem of discoloration of silver-based antibacterial agents. It is non-toxic, low-cost, and has good antibacterial effects on most common microorganisms such as Escherichia coli, Staphylococcus aureus, and Aspergillus niger. Nanoparticles can also be added to paper, plastic, cartons and composites for packaging foods, which can extend the shelf life of packaged foods. Paper made of a porous inorganic substance and organic flavonol can absorb abnormal odors such as ammonia. The anatase titanium dioxide having a thickness of about 30 mm has an extremely strong antibacterial and deodorizing function. Therefore, the paper produced therefrom has a deodorant function.

Moisture proof

Dip-coated paper can improve the moisture-proof performance, and can be used to make rainproof bags and bag-proof bags for fruit tree nursery. Such as incorporation of nano far infrared powder, this powder using high-quality natural minerals as raw materials, processed by a special nano-powder preparation process of functional ultrafine powder. When it absorbs the heat from the outside, it can release far-infrared rays with a wavelength of 4-14 microns. It has special far-infrared radiation function, it is harmless to the human body and can receive the obvious effect of warmth and dehumidification.

Heat and fire resistant

The paper made of specially processed pulp has good heat resistance and water vapor absorption properties and can be used as a microwave food packaging box. Such as the incorporation of nano-UV powder, the powder itself is non-toxic and harmless, can shield, absorb ultraviolet light, has obvious anti-ultraviolet radiation capacity. Paperboards made with it can withstand high temperatures. Paper made from the mixing of aluminum hydroxide and natural pulp or mixed with phosphorized pulp and glass fiber has good heat and flame resistance. Such as the addition of nano-light conductive powder made of cardboard, with fire-resistant, high temperature performance.

Acid and oil resistant

The paper made of a mixture of special pulp and additives has excellent shading and acid resistance. If the inorganic inorganic antibacterial powder is injected into the pulp, it can be permanently combined with the polymer substrate, and the paper made by mixing this powder has the functions of acid resistance and alkali resistance. The inner layer of the board is treated with oil-resistance to prevent the oil from penetrating. The surface of the board can be printed with a general paint treatment. The board is mainly used for the packaging of oily equipment.

Antisepsis, anti-mildew

Papers made of cristobalite and activated carbon can be used to make corrugated cartons that transport flowers. They can absorb hydrogen sulfide that causes spoilage of flowers. Incorporating nano-sized titanium dioxide powder (this is a white powder, crystal is divided into anatase and rutile) cardboard, paper, can play a role in anti-corrosion, anti-mildew. The main function of anatase crystals is antibacterial, antiseptic, and mildewproof; the main function of rutile crystals is to enhance, toughen, and degrade organic contaminants.
