- Oct 13, 2020-

Background technique:


Latex gloves are a kind of gloves, which are different from ordinary gloves and are made of latex. It can be used as household, industrial, medical, beauty and other industries, and it is a necessary hand protection product. The latex gloves are made of natural latex and matched with other fine additives. The products have special surface treatment and are comfortable to wear. They are widely used in industrial and agricultural production, medical treatment, and daily life. The latex gloves on the market currently contain protein due to the raw materials of the latex gloves, and the gloves containing protein can cause the wearer to cause protein allergy symptoms.
