Over the years, the manufacturing process and design of oil bottle PET preforms have undergone significant advancements. Several key innovations have made PET a preferred material for packaging oil products. Let's explore some of these developments:

The quality of the PET resin used to create preforms has seen major improvements. Early PET preforms were prone to leakage and poor barrier properties, which could lead to a shorter shelf life for products like edible oil. Advances in resin formulation have significantly improved the barrier properties of PET, making it more resistant to oxygen, moisture, and UV rays. These improvements are especially crucial for oils, as exposure to light and air can cause oils to oxidize and go rancid.

As the demand for various types of oils, such as olive oil, sunflower oil, and cooking oils, grew, PET preform manufacturers began to focus on customizing preforms to suit the specific needs of each oil type. For instance, oils with high UV sensitivity may require preforms with added UV protection, while products that need higher durability might require thicker preforms or specific neck designs to accommodate different bottle closures

Additionally, PET preforms are now designed with different features such as wider necks for easy pouring, ergonomic shapes for better handling, and tamper-evident features to ensure product integrity. This level of customization has expanded the range of oil products that can be packaged in PET bottles, from small retail bottles to large industrial containers.

Advancements in molding and injection technology have made it possible to produce PET preforms at a faster pace and with even greater precision. High-speed injection molding machines now allow for the mass production of preforms with consistent weight, size, and shape. This improvement has not only enhanced production efficiency but also reduced the overall cost of production.

In terms of production technology, we adopt new raw materials, and reduce dust and magazines generated in the heating process through centralized drying and feeding mode. The production process is highly mechanized, so that the production of the bottle embryo transparency is high, less black spots, the quality of the bottle embryo testing in strict accordance with the national standards, is the customer to buy rest assured, with peace of mind.
