This 16OZ plastic tub for the pet food container is different from the traditional structure. It integrates the flip and the cover itself, saving the assembly process of the flip and the cover body during production. At the same time, it is more convenient for customers to open and close the cover. The unique shape of the flap, based on the principle of 180° shaft structure, adopts ultra-high tenacity food grade plastic, which can achieve a service life of 10000 times of opening and closing, and meet the functional requirements. In addition, the tub adopts the appearance design of three side in mold labeling, and the mold cavity corresponding to the height direction is deep, so the labeling process in the mold has very high process difficulties. Through the team's unremitting efforts, we solved many process difficulties such as standard warehouse, standard fixture, picking manipulator, and realized stable mass production of high-quality products.
