The 9-cavity circular PET candy packaging box adopts a circular design. Compared with the traditional square or rectangular candy box, the circular design is more unique and innovative. The circular structural design can separate each candy unit from each other, which is convenient for packaging and transportation, and can ensure the independence and integrity of each candy. Each independent cavity not only has enough space to accommodate candy, but also can prevent candy from colliding with each other during transportation. The packaging box is equipped with an easy-to-open design, allowing consumers to easily take out the candy while ensuring the safety of the candy. Its sturdiness and reusability also make it have a long service life after use. After the candy is used up, consumers can use the packaging box for other purposes, such as storing small objects, stationery or as a home decoration, which increases the added value of the packaging box.
