PP plastic pepper balls are environmentally friendly and safe, and are widely used in children's toys and food processing machinery, mainly because they are highly environmentally safe and harmless to human body. PP plastic pepper balls are used as bearings in baby carriages, with the advantages of no noise, environmental protection and safety.

PP plastic pepper balls are used as bearings in children's cars, mainly because of environmental protection and safety, and the weight of baby carriages is not big, and children don't have much weight. Although the hardness of PP balls is not high, they can completely meet the needs of baby carriages, and because the EU has a high environmental threshold for children's toys, balls made of other materials can't meet the standards recognized by the EU, and PP pepper balls are the only optional item. At present, more than 80% of foreign baby carriages use PP plastic pepper balls as bearings, while only 50% in China. However, with the increasing requirements of environmental protection, PP plastic pepper balls will be used more and more on baby carriages.
