Childproof Cap is made of polypropylene and has good formability. It can be made into a hollow container by injection blow molding, injection stretch blow molding, coextrusion blow molding, and the like. Since PP thermal stability is much better than polyethylene terephthalate, PP plastic bottles have great potential for development in the packaging field.

PP Childproof Cap has a significant cost advantage. This advantage comes from several sources:
1. The density of PP is much lighter than PET, and the same volume of bottle PP saves raw materials compared to PET.
2. It is a low investment in equipment. PET is a resin that is very easy to absorb moisture. It must be dried with special equipment before processing, which increases the investment of equipment.
3. The equipment is flexible and efficient. For the bottle factory, the general practice is to produce bottles or preforms for storage in the off-season in the off-season, but PET is easy to absorb moisture, the shelf life is only a few weeks, the shelf life of the preforms is limited, and the transparent PP does not absorb moisture, which can be stored for a long time. This is critical to improving the equipment utilization of the enterprise.
4. The recovered PET bottle is troublesome to clean, has weak resistance to aggressive detergents, and cannot withstand high temperature sterilization, and PP plastic bottles can be completely recycled.
