Phthalates are mainly used in PVC materials, which are widely used in toys, food packaging materials, medical blood bags and hoses, floors, wallpapers, detergents, personal care products and so on. If used in excess, it will do great harm to human body.
Phthalates play an estrogen-like role in humans and animals, which can interfere with endocrine. Soft plastic toys and children's products containing phthalates will do harm to children's liver and kidneys and cause precocious puberty. In particular, it is very unfavorable to the growth and development of boys' testicles, making boys "feminine".
In addition, chemicals such as benzene and methanol contained in the book cover will damage children's nervous system and physical development, and the fragrance emitted by the book cover will lead to insufficient intake of micronutrients such as iron, zinc and calcium, which will affect children's physical and mental health.
In addition, the solvent residue of plastic book cover is also worthy of attention. * * * There are 35 batches of samples in this project that do not meet the requirements of relevant Chinese standards. In the process of use, the solvent has a pungent smell, but its harm is far greater than the pungent smell. According to toxicity, solvents can be divided into four categories. The first and second types are highly toxic, some of them are human carcinogens, some are carcinogenic, and some may cause other irreversible toxicity (such as neurotoxicity or teratogenicity).

Avoid the harm of toxic book covers
Experts suggest that it is best to use kraft paper and calendar paper.
In Bao Shu, we should use traditional kraft paper, waste newspaper or calendar paper as low as possible to wrap the book cover, so as to reduce the harm of harmful chemicals.
Experts also suggest that parents should be careful when they are not sure whether the book cover contains toxic substances. It is best to choose PP and PE materials for plastic book covers, and it is best not to choose PVC materials.
The inspection experts of the quality supervision department also gave you a trick: you can burn the middle of the book cover with a lighter. If it burns through at once, and the smell is light, it means that it is a material with less harmful substances such as PP; If it is not easy to burn through and the smell is pungent, it means it is made of PVC with more harmful substances.
In addition, don't buy a pungent and excessively soft book cover, but also look at the clarity of the book cover. The book cover made of plastic recycled waste looks soft and can't be seen clearly through the book cover.
