The difference between ordinary white kraft paper and food grade white kraft paper

The difference between ordinary white kraft paper and food grade white kraft paper

The difference between ordinary white kraft paper and food grade white kraft paper lies in its material and application range. Ordinary white kraft paper is mainly used for packaging some non-food-related items, while food-grade white kraft paper is specially designed for food packaging, with higher quality standards and requirements.

Standard 1: Whiteness
Only a small amount of bleach is added to food-grade kraft paper, which has low whiteness and looks a little yellowish. Ordinary grade white kraft paper with a large amount of bleach added has a higher whiteness.

The raw materials of food-grade white kraft paper need to be cleaner and more hygienic, and can only be used after strict screening and testing. Generally speaking, the raw materials used in the manufacture of food-grade white kraft paper are natural cellulose materials that meet food safety standards, and do not contain harmful substances that are harmful to the human body, such as fluorescent whitening agents, lead, mercury, and azo dyes.

Differentiation Standard 2: Ash Control
Food-grade kraft paper has strict control standards, and all indicators are allocated according to food-grade requirements. Therefore, the ash content of food-grade white kraft paper is controlled at a very low level, while the ash content of ordinary-grade white kraft paper is higher to reduce costs.
Food-grade white kraft paper requires higher hygienic standards in the production process, through strict management of raw material processing, production line cleaning, packaging and storage, to ensure that food will not be contaminated. Ordinary white kraft paper does not have such strict hygiene standards and requirements.

Distinguishing standard three: test report
According to the requirements of food-grade packaging materials in my country, food-grade white kraft paper must pass the QS test, while ordinary grade cannot.
Food-grade white kraft paper has higher quality requirements and stricter hygiene standards, so it has a wider range of applications. When purchasing paper products, we should choose appropriate materials according to actual needs to ensure the health and safety of the products.

Distinguishing standard four: price
Although the price difference is not big, it is also an important reference value. Because of its thinner fibers, lighter weight and thinner thickness, food-grade white kraft paper can not only better protect the quality and freshness of food, but also reduce the weight of packaging and transportation costs, which is more beneficial to environmental protection. Therefore, the price of food grade kraft paper is higher than that of ordinary grade kraft paper.
