As the global packaging industry shifts toward low-carbon, circular and sustainable practices, CHUMPOWER Machinery Corp. (4575), Taiwan's largest manufacturer of PET blow molding machines, took part on October 30 in the 7th Plastics Industry Innovation Forum (PIIF) hosted by the Plastics Industry Development Center (PIDC). Speaking on the theme "New Trends in Circular Packaging: Design Innovation and Low-Carbon Manufacturing," CHUMPOWER shared its practical results in rPET blow molding technology, energy-saving equipment development and eco-friendly packaging, showing how machinery manufacturers can drive innovation in the circular economy.

rPET Adoption Is Rising: Blow Molding Equipment Supports the Shift to Recycled Materials

As international brands raise the share of recycled plastic in their packaging, and as the EU Single-Use Plastics Directive (SUPD) and the Packaging and Packaging Waste Regulation (PPWR) progressively introduce recycled-content requirements, rPET has become a key direction for the beverage packaging industry. Using recycled materials, however, involves more than sourcing and quality control; it also requires equipment and process technology to match.

Drawing on many years of experience in PET blow molding equipment, CHUMPOWER continues to help customers meet the demands of recycled-material applications. Through process parameter adjustments and technical support on their existing blow molding machines, customers can move gradually from conventional PET to rPET without replacing their equipment because of the change in material, extending the value of their machines and avoiding additional resource investment. CHUMPOWER has achieved 100% rPET bottle production on both its one-stage and two-stage blow molding machines, giving the packaging industry equipment-level support for increasing its use of recycled materials.

Beyond material recycling, CHUMPOWER also builds energy saving into its blow molding machine development, targeting the three main sources of energy consumption (electricity, heat and high-pressure air) and continuously optimizing mechanical structures and process efficiency.

From Energy-Saving Equipment to Lower-Carbon Products: Low-Carbon Manufacturing on Two Fronts

On the equipment side, CHUMPOWER has optimized cam curves and improved mechanism design to reduce motor load. In one design case, power consumption fell from 4.78 kW to 1.6 kW, an estimated reduction of about 3.7 metric tons of CO2 equivalent per year. Closed-loop heating control, automatic lamp power adjustment, and high-pressure air recovery and reuse further improve energy efficiency, with high-pressure air recovery rates reaching 20% to 30%, a tangible measure of the equipment's energy savings.

CHUMPOWER has also introduced power monitoring equipment to track machine energy consumption. The data serves as an important basis for subsequent energy management and energy-saving improvements, moving its blow molding machines toward smarter, lower-carbon operation.

Expanding into Eco-Friendly Packaging with Diverse Circular Solutions

In addition to PET blow molding equipment, CHUMPOWER is actively expanding into eco-friendly packaging. Its eco-friendly composite container uses an easy-to-separate paper-plastic structure: after use, the paper and the plastic liner can be separated by hand, so each material can enter its own recycling stream. CHUMPOWER has also developed matching automated production equipment, extending circular design principles to the packaging manufacturing stage.

CHUMPOWER believes that different packaging materials each suit different applications, and that the key to circular packaging lies in integrating product design, manufacturing efficiency, material properties and recycling systems. Going forward, the company will continue to center on equipment innovation, deepen its recycled-material and low-carbon manufacturing technologies, expand into diverse packaging applications, and work with customers to improve resource efficiency and advance the sustainable development of the packaging industry.
