The application of titanium dioxide coating in different plastic packaging products has extensive advantages and can provide multiple functions according to different needs. A variety of applications make titanium dioxide coatings a key material to improve functionality and aesthetics in plastic packaging industry.

Titanium Dioxide Coating for Plastic Film

Inner coating: coating titanium dioxide coating on the inner layer of plastic film used for food packaging can block oxygen and water vapor and prolong the shelf life of food. At the same time, the white color of titanium dioxide can cover up some defects in the film production process and improve the appearance quality of the film.

Outer coating: coating titanium dioxide coating on the outer layer of plastic film is mainly to improve the weather resistance and printability of the film. The tinox tio2 in the coating can absorb and scatter ultraviolet rays, protect the film from ultraviolet rays and prevent the film from aging and embrittlement. In addition, the coating can also improve the roughness and polarity of the film surface, enhance the adhesion to ink, and make the printed pattern clearer and firmer.

Titanium Dioxide Coating for Plastic Containers

Integral coating: For plastic containers such as plastic bottles and cans, the integral coating of titanium dioxide coating can provide comprehensive protection and decorative effect. The titanium dioxide coating formed on the surface of the container can prevent the plastic from being eroded by the external environment and increase the chemical resistance and wear resistance of the container. At the same time, the white coating can make the container surface whiter and more beautiful, which is convenient for printing brand logo and product information.

Partial coating: According to the design requirements, sometimes the plastic container is partially coated with titanium dioxide coating, such as the bottle neck, bottle shoulder or bottle bottom, to achieve specific functions or decorative effects. For example, coating titania tio2 paint on the bottleneck of cosmetic plastic bottles can increase the hardness and gloss of this part and enhance the delicate feeling of the products.

Titanium Dioxide Coating for Plastic Sheets

Single-sided coating: titanium dioxide coating is coated on one side of the plastic sheet used for blister packaging. The coated surface can be used as the outer surface of the packaging after blister molding, which can provide good whiteness and gloss, make the blister packaging more beautiful and attract consumers' attention. At the same time, the coating can also improve the surface strength of the sheet and prevent it from being scratched during transportation and use.

Double-sided coating: for some plastic sheets that need higher barrier performance and decorative effect, titanium dioxide coating will be applied on both sides. Double-sided coating can better block moisture, gas, etc., and protect the products in the package. In some high-end gift packaging and electronic product packaging, plastic sheets coated on both sides can show better texture and visual effects.
