Avoid scented stationery

When choosing stationery, avoid products that may have an attractive appearance or aroma, but may contain high-risk chemical components. The so-called "fragrant stationery" is actually stationery with added fragrance agents. Some manufacturers improperly use inferior fragrances containing harmful chemicals such as aromatic hydrocarbons, phenols, aldehydes, alkanes, mercury, lead, etc. in the production process. Therefore, it is recommended to choose stationery with a simple appearance, light aroma or odorless taste, and avoid strong smelling correction fluid, erasers, highlighters, backpacks, etc.

■ Pay attention to the material when purchasing solid (liquid) adhesive

The commercially available solid adhesives can be mainly divided into three types based on the adhesive used: polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP), and acrylic ester (ACR). The solid adhesive made of PVA material needs to undergo a condensation reaction with formaldehyde during the preparation process to increase its adhesive strength, thus there is a problem of containing free formaldehyde. Excessive free formaldehyde can be harmful to health. When selecting solid adhesive, it is recommended to choose PVP material. For those who pursue beautiful colors, ACR material can be chosen, but quality must be ensured.

The paper of the notebook should not be too white

It is recommended to use paper with a natural yellowish color, and the brightness (whiteness) of the paper and workbook should not exceed 85% according to standard regulations. When purchasing, you can place the workbook in the sunlight to feel if it is dazzling.

■ The pen cap should be as large as possible and have breathable holes

For the safety of children, when choosing a pen cap, one should consider whether its size is large enough to avoid accidental ingestion, or ensure that the cap has breathable holes or safety gaps to comply with international safety standards. The breathable holes on the pen cap can prevent suffocation in case of accidental ingestion by children.

Choose a regular plastic book cover

The book cover should focus on whether the content of plasticizers such as phthalates meets the requirements. Excessive intake of ortho benzene can lead to early puberty in children. So it is necessary to choose a legitimate manufacturer for production, with inspection reports and no pungent odor.
