In recent years, China’s dairy industry has been booming. The output and total output value have increased by more than 10 times in the last 10 years, which has gradually attracted the attention of the world. Although compared with developed countries, China’s dairy industry started late, but thanks to China’s fast-developing economic level and huge population base, the penetration rate of dairy products has increased rapidly, and the industry has developed rapidly. In 2019, China’s dairy products market reached 428.4 billion yuan (equivalent to 61.9 billion U.S. dollars), ranking second in the world. At present, China’s dairy product market has transitioned from a rapid increase in penetration rate to the current price-driven stage.



At the beginning of 2020, dairy products were greatly affected by the epidemic. For the whole year, listed companies achieved revenue growth of 3.63% and a net profit decline of 14.49%. Profits were affected by factors such as the epidemic and costs. In the post-epidemic era, consumers’ demand for dairy products has increased. In 2021 Q1, revenue and profits of the sector have increased by 35.89% and 199.36%, which are 22.92% and 22.20% respectively over the same period in 2019 Q1. The industry has made a good start in the first quarter.

Consumers have increased their attention to the ease of use of packaging and sustainable development, and liquid dairy products in PET bottles have been sold on the market.



1) Thanks to the low cost of raw materials, reducing PET bottle weight not only saves costs but also increases output and protects the environment.

2) PET can be blow-molded into various shapes and sizes, and the label design is diversified, providing more possibilities than cartons, thereby increasing brand recognition.

3) Compared to HDPE packaging, PET bottles have a superior oxygen barrier, leading to better preservation of taste and flavor, and longer shelf life even under the same storage conditions.

4) PET can be added with color masterbatch to achieve high light resistance and has a good light barrier effect on some photosensitive products.

5) PET material is strong, tough, easy to transport, and has low loss.

Understanding the Basics: Introduction to Vertical Blow MoldingBlow molding is a highly efficient and popular method used in the manufacturing industry to create various plastic products. At TECH-LONG, a renowned brand in the field of blow molding machines, we understand the importance of comprehending the basics of this process. In this article, we will provide a detailed description of the fundamentals of blow molding, focusing specifically on the vertical blow molding machine.

Blow molding is a manufacturing process used to produce hollow plastic products, such as bottles, containers, and toys. It involves melting a thermoplastic material, typically in the form of pellets, and then shaping it into a desired form using a mold. The primary types of blow molding include extrusion blow molding, injection blow molding, and stretch blow molding.

The vertical blow molding machine, as the name suggests, operates vertically and is designed to produce bottles and containers of various sizes and shapes. This machine consists of several key components, including an extruder, a mold, a parison programming unit, and a clamping system.

The first component, the extruder, plays a significant role in the blow molding process. It is responsible for melting the plastic material, such as high-density polyethylene (HDPE) or polypropylene (PP), and then extruding it in the form of a hollow tube known as a parison. The parison is then suspended vertically within the mold.

The mold is another essential component of the vertical blow molding machine. It is precisely designed to impart the desired shape and features to the final product. The mold consists of two halves that come together to form the desired cavity, within which the parison is located. The mold is heated to prevent the plastic material from cooling too quickly and to ensure proper molding.

To ensure precise control over the shape and dimensions of the final product, the vertical blow molding machine incorporates a parison programming unit. This unit allows the operator to adjust the thickness and length of the parison, ensuring consistent results across multiple production cycles. This level of control is especially crucial when producing bottles with customized features, such as handles or curves.

The clamping system of the vertical blow molding machine is responsible for holding the mold halves together during the molding process. It ensures that the parison is properly sealed within the mold, preventing any leakage or deformities. The clamping mechanism can be hydraulic, pneumatic, or mechanical, depending on the specific requirements of the machine.

TECH-LONG, recognized for its expertise and innovation in blow molding technology, offers a range of vertical blow molding machines tailored to meet various production needs.
