Traditional two‑step production lines feature lengthy processes, high energy consumption and high processing costs, limiting production flexibility and profit margins for packaging manufacturers.
Wuhan Handern Machinery Co., Ltd.has developed the world‑first one‑step PP corrugated sheet machine, overcoming long‑standing technical pain points in the industry. This advanced production line delivers prominent competitive advantages in process simplification, cost efficiency, end‑product performance, intelligent operation and high‑filler adaptability. It triggers a cost‑saving revolution for the global packaging industry and supports high‑value reuse of various bulk industrial solid wastes.
1. Streamlined Workflow Without Pelletizing, Sharply Cutting Processing Expenses
Traditional two‑step technology requires two melting‑extrusion cycles: first producing filled masterbatch from fillers and polymer raw materials, then re‑melting the masterbatch to manufacture corrugated sheets. Double melting and pelletizing generate substantial extra processing costs.
The one‑step PP corrugated sheet machine from Wuhan Handern Machinery Co., Ltd. eliminates the pelletizing procedure. Powder materials, PP resin and additives are proportionally mixed and directly extruded into finished corrugated sheets in one single pass, saving over USD 57 per ton on pelletizing‑related costs.
Conventional two‑step processing cost stands at around USD 184 per ton, while the one‑step line drops processing cost to approximately USD 71 per ton, representing over 60 % reduction in processing expense.
Co‑developed with the research team of Academician Qu Jinping, the intensified transfer dual‑rotor extruder solves uneven dispersion challenges under high inorganic filler loading. The machine achieves a maximum capacity of 600 kg/h with up to 50 % lower processing energy consumption, greatly lifting overall production efficiency.
2. Material‑Level Cost Reduction & Valorization of Industrial Solid Waste
The one‑step production line supports high‑loading inorganic fillers. Phosphogypsum and fly ash can replace conventional calcium carbonate, and secondary recycled PP plastic can also be adopted, bringing more than 30 % raw‑material cost reduction.
Phosphogypsum is an industrial by‑product solid waste. Its lamellar microstructure improves tensile strength and flexural performance of final corrugated sheets. The filling ratio of phosphogypsum can reach 60 %‑70 %. It not only consumes large‑volume industrial solid waste but also lowers powder purchasing expenditure.
When adopting modified secondary recycled PP material, the total production cost of phosphogypsum‑based PP corrugated sheet can drop to USD 411 per ton, making it price‑competitive versus conventional moisture‑proof corrugated paperboard. Additionally, products containing ≥40 % phosphogypsum qualify for VAT rebate policies, further improving project profitability.
To offset defects including unstable color caused by recycled feedstock and industrial solid waste fillers, Wuhan Handern Machinery Co., Ltd. provides the industry‑leading fully‑automatic high‑speed laminating technology. An ultra‑thin PP film is laminated onto sheet surfaces to satisfy high‑grade printing requirements and boost mechanical strength. The laminated PP film shares identical material properties with the substrate. The whole product can be crushed and recycled without separation, realizing full‑life‑cycle circular utilization.
3. Complete Intelligent Equipment with Full‑Process Digital Production Control
Wuhan Handern’s one‑step PP corrugated sheet machine is equipped with advanced intelligent control hardware: 500‑column PLC, EtherCAT fieldbus and self‑tuning PID temperature control with precision of ±0.1 ℃. Integrated modules cover automatic batching & mixing, precision cutting and automatic stacking. Optional online edge‑material recycling system is also available for fully automated operation.
The production line supports data visualization and IoT remote management. Operators can monitor extrusion speed, sheet gram‑weight & thickness, real‑time/daily/monthly output, equipment standby time and fault logs via on‑site HMI panels, multi‑line centralized dashboards, mobile phones and PCs. Alarms are pushed to mobile terminals upon malfunctions. Remote program diagnosis and equipment monitoring are supported, facilitating shift management, equipment maintenance and production performance analysis with minimum manual intervention.
4. Superior Product Performance, Wide Application Range & International Compliance
Benefiting from high dispersion performance of dual‑rotor extrusion technology, high‑filler PP corrugated sheets feature hollow grid structure and inherit core merits of corrugated packaging: water & moisture resistance, antibacterial fresh‑keeping, high compression & abrasion resistance, freeze resistance, stain resistance and non‑toxicity. They fit diverse scenarios including agricultural produce packaging, e‑commerce logistics, cold‑chain transport, pharmaceutical packaging and industrial component turnover boxes.
Tested by authoritative institutes such as SGS, phosphogypsum‑filled corrugated sheets produced by Wuhan Handern Machinery Co., Ltd. outperform traditional paper cartons in mechanical properties. They satisfy food‑contact safety standards of EU and the United States, suitable for packing fruits, seafood, eggs and other food commodities. Industry calculation shows that if phosphogypsum‑based corrugated boxes replace 20 % of paper‑based packaging, over 10 million tons of phosphogypsum can be consumed annually, offering a feasible industrial solution for bulk solid waste consumption.
5. Turn‑key Solution with Full‑Chain Technical Support
As a National‑Level Specialized, Refined, Differential & Innovative “Little Giant” enterprise, Wuhan Handern Machinery Co., Ltd. is a pioneer for domestic substitution of high‑end polymer extrusion equipment. Beyond standalone main machines, the company supplies complete automated production sets covering material feeding & mixing, extrusion, stacking, laminating, high‑definition printing, die‑cutting and box forming, delivering full turn‑key projects.
