For years, a persistent myth has circulated within the packaging industry: "Going 100% biodegradable means losing 20% of your output." At the recent CHINAPLAS 2026, this was the most frequent concern raised by manufacturers. The transition to PLA, PBAT, and starch-based blends is often associated with technical headaches—bubble instability, thickness variation, and significant downtime.

If you are running high-barrier packaging film, the math is becoming brutal. With global PP and PE resin prices surging by 24% earlier this year due to regional conflicts and supply chain disruptions, every gram of wasted barrier material eats directly into your net profit. At these astronomical costs, uneven film thickness at high extrusion speeds isn't just a quality control hiccup—it is a catastrophic margin killer.

Unlike previous years, they faced a critical logistical hurdle: obtaining adequate booth space was incredibly difficult. Instead of backing down or bringing a brochure, they chose the hard path: they brought the machine.
