CJ Logistics rolls out AI-powered overpackaging detection system at 26 fulfillment centers

CJ Logistics announced Thursday that it has deployed PackCheck — an AI-based overpackaging diagnostic solution developed by its TES Logistics Technology Research Institute — across 26 logistics centers nationwide.

CJ Logistics is the first company in the logistics industry to develop an AI-powered algorithm for overpackaging regulation compliance and apply it in actual logistics operations. The company filed related patent and trademark applications in April.

The overpackaging regulation enforced by the Ministry of Climate, Environment and Energy limits each product to a single layer of packaging and requires that the void-fill ratio — the share of empty space inside a box excluding the product — remain at or below 50 percent. A lower ratio means the box fits the product more closely, reducing packaging waste. The regulation applies to cardboard boxes, plastic pouches and styrofoam packaging alike.

However, four categories are exempt: bundle packaging of two or more products, reuse of packaging materials, breakage-prone items such as glass and ceramics, and irregularly shaped products that are unusually long or flat.

PackCheck automates what had previously required manual judgment by simultaneously analyzing both the applicable standards and the exemption criteria under the overpackaging regulation. CJ Logistics has integrated product information from client companies stored at its fulfillment centers with PackCheck, enabling the system to instantly assess whether a product is overpackaged and recommend corrective measures such as switching box sizes or using paper cushioning. Workers follow the system's guidance to meet regulatory requirements while also improving productivity.

CJ Logistics had been building out eco-friendly packaging technology well before PackCheck was developed. Its box recommendation system, Lois O-Pack, uses a 3D simulation-based loading algorithm to optimize bundle packaging and reduce void space. The company has also developed a self-adhesive air-cap material that requires no separate tape, helping cut plastic tape consumption.

"As the overpackaging regulation takes effect, the importance of technology that allows workers on the ground to apply packaging standards more easily and accurately is growing," said Kim Jeong-hee, head of CJ Logistics' TES Logistics Technology Research Institute. "We will continue to advance PackCheck so that compliance becomes simpler and more precise, while achieving both packaging efficiency and environmental protection."

Meanwhile, CJ Logistics has been broadening its customer touchpoints through various marketing efforts, including a campaign for its integrated delivery brand O-NE to raise awareness of its peer-to-peer delivery service "Bonaone" and communicate the brand's service strengths to consumers.
