refastened PP side tape

The PP side tape in diapers is usually made of polypropylene (PP, Polypropylene) material. Polypropylene is a thermoplastic polymer commonly used in the manufacture of non-woven fabrics, films, plastics and other materials. It has good chemical stability, moisture resistance, toughness and heat resistance, so it has been widely used in the design of diapers. In diapers, adhesive side tape has the following main functions:   Fixation: They can help diapers fit the baby's waist better through the design of adhesive tapes, ensure the stability of diapers, and prevent urine leakage. Comfort: Polypropylene material is relatively soft and can provide a certain degree of comfort while ensuring fixation, without causing excessive friction or discomfort to the baby's skin.   Adjustability: The left and right tapes of PP material are usually adjustable. Through the design of adhesive strips, parents can adjust the tightness of diapers according to the baby's body shape and needs to achieve a better wrapping effect. In actual production, the left and right tapes of PP material are usually fixed to the side of the diaper through heat sealing technology or ultrasonic welding technology. When used, the size of the diaper can be adjusted by bonding or re-adhesion. PP material is not only light but also durable, so it is widely used in the production process. In short, the refastened PP side tape in diapers is mainly made of polypropylene (PP) material, which is soft, light and high-strength, ensuring the comfort and functionality of diapers.
