Ning adds that innovations such as barrier coating technologies are expanding the range of products that can be packaged in PET while supporting sustainability, product protection and cost-reduction goals.

“Originating from coating technologies utilized in the pharmaceutical industry, where product safety and quality assurance are among the most demanding requirements, KHS Plasmax applies an ultra-thin glass layer to the inner surface of PET bottles,” Ning explains. “This enables producers to achieve glass-like barrier performance while maintaining all the operational and sustainability advantages of PET packaging.”

Krones’ Lee considers digitalization to be transforming the plastic bottle packaging industry. 

“At Krones, we are pioneering the integration of digital technologies across the entire production process,” he says.  “From real-time data analytics to predictive maintenance and smart line control, our digital solutions empower customers to achieve new levels of transparency, efficiency and reliability.”

Lee further notes that AI is unlocking new possibilities for quality and efficiency. 

“Artificial intelligence enables smarter process adjustments, faster and more accurate inspection, and proactive defect detection in bottles, caps and labels,” he says. “By continuously monitoring environmental and material variables, AI-driven systems can autonomously optimize machine performance ensuring consistent product quality and reducing waste. For example, our cutting-edge Contiloop AI technology measures the most important container parameters and environmental parameters inline and readjusts the blow molding process if necessary.”

KHS’ Ning says that AI is expected to play an increasingly important role in plastic bottle manufacturing by making equipment smarter, more efficient and more predictive.

“As manufacturing environments become more connected, AI can help improve maintenance planning, optimize production processes, enhance quality inspection, and reduce energy and material consumption,” she explains. “By supporting more informed, real-time decision-making, AI has the potential to improve both operational performance and sustainability outcomes across the production process.”

Sidel’s representative notes that the company’s data intelligence tools such as IntelliADJUST and Evo-ON are helping manufacturers move from reactive monitoring to more proactive process management.

“IntelliADJUST automatically adjusts heating and blowing parameters in real time, helping improve bottle consistency, reduce waste and maintain uninterrupted production,” they explain. “When combined with Evo-ON's analytics capabilities, manufacturers gain greater visibility of line performance, supporting improvements in efficiency, quality and overall equipment effectiveness.”
