When looking for pet packaging bottles, some purchases may just follow the diagram and find bottles that meet the company's appearance requirements. However, for some details, they may not be clear. Next, let's follow Yuheng Plastics to learn some common knowledge about the various parts of pet packaging bottles.

1. PET packaging bottles have nominal capacity and full mouth capacity, and the full mouth capacity is generally larger.

2. There are various shapes of plastic bottles, including circular bottles, square bottles, elliptical bottles, wide mouth bottles, and special-shaped bottles. Each has its own advantages and can be selected according to different usage needs.

3. The sealing performance of a bottle depends on the size of the bottle mouth and cap.

4. The design of the bottle shoulder is very important, and what affects the strength of the bottle shoulder is the inclination angle of the bottle shoulder. If the design of the bottle shoulder is too flat, it may collapse.

5. The thickness of the bottle body is generally between 1.2 and 1.5 millimeters, and now the packaging of the bottle body is getting thicker and thicker.

6. The bottom of the bottle generally protrudes inward, with a double rounded structure being the majority, which can better withstand pressure.

When choosing a pet packaging bottle, we not only need to consider whether the bottle shape and capacity are suitable, but also consider its structural design, detailed handling, and rationality.
