The main raw material of PP strapping tape is polypropylene. According to the different raw materials, it can be divided into three types: pure material, recycled material, and sandwich material. Among them, the pure material PP strapping belt is also called new material and contains a higher polypropylene component. Let's take a look at the respective characteristics and differences between these two types of packing.

PET packing belt is more suitable for large paper coupons, cartons, plastic films (bags) and other materials, and more. Suitable for long-distance transportation use.
