What is the OBA Free standard?

What is OBA?

OBA (Optical Brightening Agent) is a versatile optical brightener that is used in many fields, such as: plastic processing, papermaking, textile, dyeing and even cosmetics. Having good heat resistance, OBA is a chemical used to increase the whiteness of the product. However, OBA is an unstable molecule, so products containing OBA often do not retain a bright white color but turn yellow after a period of time. In addition, the more paper types that use OBA, the more difficult it will be to control the print color quality. Therefore, only those papers that really need high whiteness in products need to use this chemical.


What is OBA Free? How does it work?

OBA Free paper means that the manufacturer does not use optical brighteners to increase the whiteness of the paper. The whiteness of OBA Free standard paper is usually based on natural colorants, which give realistic colors. These types of paper do not achieve the perfect whiteness as OBA paper but the ability to catch color, color up and control color when printing is much easier. Moreover, the color of the product is also durable and does not fade over time.


Limiting the use of chemicals in paper and plastic will also be better for users' health, especially for products with direct impact such as plastics, paper used for food, cosmetics, ...


Through the above article, you must have understood why many manufacturers promote their products that meet the OBA Free standards. Xuong Giang Paper is a reputable consumer paper manufacturer, committed to not using bleach that causes harm to users and the surrounding environment.
