Boost Line Throughput: CES-900 Carton Erector + PWS-800 Pallet Wrapper Perfectly Match Palletizing Robot

A few months back, a drinks factory in Ohio ran into a really annoying production problem. They just bought a Palletizing Robot that stacks 18 cases every minute, but nothing else on their line could keep up. The old carton erector only cranked out 10 boxes per minute, and workers still had to wrap pallets by hand every four minutes. That expensive Palletizing Robot sat doing nothing for almost half every shift, all because their upstream and downstream gear couldn’t match its speed.

This issue is super common for mid-size packaging plants that only have partial automation. Random manual steps break the whole workflow and drag down total output. As the main brand of Wuxi Transfo Intelligent Packaging Co., Ltd., STRANS hears this exact complaint from factory owners across Europe and North America every single year. To fix the bottlenecks right before and after your palletizing station, we built two brand-new machines: the CES-900 carton erector and PWS-800 Pallet Wrapper. Both have been shipping to global customers starting last month.

 

This erector makes up to 25 cartons every minute, but its biggest selling point is lightning-fast size switching. Traditional box erectors use hand cranks and mechanical parts to adjust sizes; even skilled workers need 15 to 20 minutes to switch between regular box formats. The CES-900 uses servo folding arms with pre-saved size settings on its touchscreen HMI. Just pick your box size and hit start — the machine reconfigures itself automatically in only 60 seconds, no maintenance staff required. Line workers can tap the screen, step away for a quick coffee, and come back to a fully ready machine.

Two side-by-side storage magazines each hold 150 flat carton blanks. You can run nonstop for over 20 minutes before refilling, cutting down constant manual feeding work. It fits boxes from 250×200×150mm up to 600×500×500mm, covering nearly all standard packaging sizes for food, drinks, daily chemicals and online retail. It only takes up 3.2 square meters of floor space, so it easily fits into older factories that don’t have extra room for new equipment. It links straight to downstream case sealers via Ethernet/IP without extra controllers, and both machines auto-match speeds to stop empty boxes piling up between stations.

 

PWS-800 Smart Pallet Wrapping Machine: Auto-Read Loads, Slash Stretch Film Costs by 35–40%

A reliable Pallet Wrapping Machine keeps your goods safe during shipping, but most basic Pallet Wrapper models use one fixed tightness setting for every pallet. If you wrap heavy loads too loose, boxes collapse mid-transit; if you wrap light empty containers too tight, you waste tons of stretch film. The PWS-800 fixes this hassle by scanning each pallet’s weight and size as it wraps, and instantly adjusting film tension on the go. It stretches film up to 300%, and our customers cut their stretch film spending by 35–40% compared to regular fixed-tension machines.

 

Our customers love its auto film cut and clamp feature most. Once a pallet finishes wrapping, the machine snips the film and locks the loose end down automatically — no more walking back and forth to cut film by hand. For lines wrapping more than 30 pallets each shift, this feature alone saves around 1.5 hours of manual labor every day, letting your team focus on other important jobs. It runs on a Siemens S7-1200 PLC, the same control system used on the CES-900 and all our STRANS packaging gear. If you build a full production line paired with Horizontal Flow Wrapping Machinery, all your machines connect to one unified control system, no extra adapters or custom coding needed.

 

Buy just the carton erector, and you’ll only save labor on box forming. Grab a single Pallet Wrapper, and you’ll only cut film waste and wrapping labor. The real huge boost in production speed happens when you run both machines with your Palletizing Robot as one connected, smooth line. Separate box making, robotic palletizing and manual wrapping create mismatched speeds and tons of idle machine time. When you pair the CES-900 and PWS-800, your whole line runs a steady 25 boxes per minute, unlocking the full working capacity of your Palletizing Robot — that’s exactly why we launched these two machines as a matched set.

 

We build both machines entirely at our 15,000 sq.m factory in Wuxi. Every step from precision CNC cutting to full final assembly is done in-house. Our standard delivery lead time is 45 days, with CE certification for Europe and UL certification for North American customers. If you can’t fly out to China to inspect the machines in person, we offer virtual factory acceptance tests. On-site installation and setup are included with every order. Our sales team can draw custom production line layouts within a few working days using your factory floor plan, plus share full technical specs and clear pricing. You can also order the carton erector or Pallet Wrapping Machine separately if you don’t need the full set, with the same specs and delivery timeline guaranteed.
