How Automated Waste Stripping Systems Are Reshaping Packaging Production Lines

Introduction – Meet the Protagonist: The Challenge of a Packaging Giant

In the ever-evolving world of packaging, where speed, precision, and cost efficiency determine a manufacturer’s competitiveness, even the most established players must adapt or risk falling behind. One such story belongs to Golden Pack Printing & Packaging Co., Ltd., a leading corrugated packaging producer based in Toronto, Canada.

For over two decades, Golden Pack has been the preferred packaging partner for top consumer goods and e-commerce brands across North America. With a massive 20,000-square-meter production facility, the company’s reputation was built on timely delivery, high-quality print, and custom carton design capabilities. However, as market demand shifted toward shorter lead times, higher order variability, and tighter cost controls, their traditional manual production setup began to show its limits.

Before 2023, Golden Pack’s production line relied heavily on manual waste removal after die-cutting—a tedious, labor-intensive process that created significant bottlenecks. While the company invested in modern die-cutting and printing equipment, the waste stripping stage remained outdated, inconsistent, and costly.

As their business volume grew, so did the problems: inconsistent output, operator fatigue, excessive labor costs, and poor utilization of expensive die-cutting equipment. GoldenPack’s management knew something had to change.

Conflict – The Struggles of Manual Waste Removal

Before adopting Chaoyi’s automated solution, GoldenPack’s waste management process was a mix of outdated machinery and manual operations. After each batch of corrugated sheets was die-cut, operators had to manually strip off the remaining waste edges and inner cut-outs using simple hand tools.

This method not only slowed production but also led to severe inefficiencies across multiple levels:

1. Low Efficiency and Frequent Downtime

Each operator could only process around 400–500 sheets per hour, depending on the complexity of the carton design. When compared to the die-cutting machine’s output of 2,000 sheets per hour, the mismatch created a serious production bottleneck. In some cases, finished die-cut sheets waited up to 5 hours for waste removal, leading to delayed deliveries and customer complaints.

2. High Labor Costs

The company employed more than 40 workers solely for waste stripping, distributed across three shifts. With rising wages in Canada and increasing difficulty in hiring experienced operators, labor became an unsustainable burden. According to GoldenPack’s production manager, “Every year, we were spending over $400,000 just on waste removal labor costs—that’s almost 12% of our total production expenses.”

3. Quality and Safety Concerns

Manual waste removal often caused damage to finished cartons—scratches, bends, or torn edges that rendered boxes unsellable. Worker fatigue also led to inconsistent quality, while repetitive motions resulted in occupational injuries. GoldenPack’s rejection rate due to stripping-related defects averaged 2.5%, a figure far above the industry benchmark.

4. Unbalanced Production Flow

The die-cutting and printing sections frequently had to pause operations because the waste stripping stage couldn’t keep up. As a result, machine idle time increased, and productivity across the entire line suffered. “It felt like we were running a marathon with one leg tied,” recalls Mr. Robert Lee, GoldenPack’s Operations Director.

By late 2023, despite the company’s continuous effort to optimize workflow, it became evident that manual waste stripping was the weakest link. GoldenPack needed a modern, automated solution that could match their high-speed production demands and support future smart factory goals.

Solution – Introducing CHAOYI’s Automated Waste Stripping System

In early 2024, GoldenPack’s leadership began evaluating potential automation partners. After months of research and supplier visits across Asia, they discovered Guangxi Chaoyi Machinery Co., Ltd., a Chinese manufacturer renowned for its specialization in carton waste strippers.

Unlike other machinery brands that produce a wide range of equipment, CHAOYI focuses exclusively on waste stripping systems, which means every detail—from blade design to ergonomic handling—was engineered to address real-world stripping challenges.

Why GoldenPack Chose CHAOYI

What impressed GoldenPack most was CHAOYI’s diverse product range and customized solutions. The company offers two main categories:

External Waste Strippers – available in pneumatic and electric versions, ideal for removing side edges and outer waste sections quickly.
Internal Waste Strippers – semi-automatic models designed for precise removal of inner holes and complex shapes within the carton layout.

After an on-site demonstration at CHAOYI’s headquarters and a successful pilot test in GoldenPack’s facility, the management team decided to invest in a full automated waste removal system combining both external and internal stripping solutions.

Key Features Implemented

The newly installed CHAOYI system included several breakthrough technologies that transformed GoldenPack’s operations:

High-Speed Pneumatic External Waste Stripper
- Capable of processing up to 2,000 sheets per hour, perfectly synchronizing with die-cutter output.
