Jingye Machinery: One-Step Production of Multicolored Plastic Bottles, Saving Post-Spraying Costs

At the recently concluded China International Packaging Exhibition SWOP, Liuzhou Jingye Machinery Co., Ltd. showcased its groundbreaking innovation (environmental features) of an all-in-one, fully automatic PET dual-color injection stretch blow molding process in the plastic packaging machinery hall, making it a highlight of the exhibition and attracting the attention of numerous professional visitors.

The Jingye one-step PET material dual-color injection stretch blow molding machine attracts many spectators.

Core Technological Advantages

01Breakthrough innovation: Achieving dual-color molding technology for PET materials on a one-step injection-blow molding machine. Utilizing the patented technology of Jingye Machinery (Patent No.: ZL202322921800.4).

02The traditional two-color production model involves applying color to a monochrome bottle body through subsequent spraying, which increases costs, energy consumption, paint waste, environmental pollution, and is not conducive to later recycling.

PET two-color bottles produced on-site at the exhibition, "one out of six cavities."

Against the backdrop of global advocacy for "green, environmentally friendly, and carbon reduction," Jingye Company has consistently integrated the concept of sustainable development into technology research and product innovation. PET materials, with their advantages of being lightweight and safe (replacing glass bottles), are widely used in beverage bottles, daily chemical containers, and other fields. Their recycling and reuse have become a focus internationally, with Europe specifically legislating to promote this.

Jingye Machinery produces PET, PC, PETG, PCTG, and PP dual-color bottles.

Cosmetic packaging emphasizes aesthetics, safety, and lightweight design, with dual-color or gradient effects enhancing individuality. However, traditional spraying methods not only increase production costs but also tend to cause pollution. Jingye has developed a proprietary dual-mixing injection-blow molding technology that enables the one-step production of dual-color gradient bottles, eliminating the spraying process and reducing energy consumption and pollution. This technology is suitable for various materials such as PET and PP, facilitating direct recycling and aligning with the innovative green and environmentally friendly concepts in the packaging industry, as well as the prevailing trends in industry development.

As early as 2017, Jingye Machinery began the research and trial production of dual-color injection-stretch-blow molding technology. After eight years of arduous efforts, they finally made a breakthrough in 2023, successfully applying it to products made of PC, PETG, PCTG, PP, and other materials! Based on this, Liuzhou Jingye has completed technological modifications to the equipment and mold structure, specifically addressing the crystallization characteristics of PET materials, showcasing Jingye's technical strength and innovative spirit in the field of packaging machinery!
