Mühlen CA 400
Packaging Filler & Cardboard Processing Machine
Fully Automatic
The MÜHLEN CA 400 processes cardboard and boxes with a dedicated blade system and prepares them as soft packaging filler material.
Easy to Use
The operator simply places the cardboard into the feed opening; the narrow inlet safely prevents contact with hands and fingers.
Emergency Stop Button
In an emergency the machine can be stopped instantly with the red emergency stop button; turning the button returns it to the operating position.
Fast and Quiet
With a processing speed of 550 cm of cardboard per minute, the machine runs quietly below 55dB and handles cardboard up to 420 mm wide.
Eco-Friendly and Economical
It converts waste boxes into reusable packaging filler, delivering a clear cost advantage and an alternative to bought-in filling material.

Automatic Trimming
Cardboard wider than 420 mm is trimmed automatically, so smaller sheets can be processed with ease.

An 800 Watt motor, a hardened steel blade system and a reverse function in case of jamming provide powerful and safe operation.

Mühlen CA 400 — Packaging Filler Machine That Turns Waste Boxes into Padding
Who Is It For?
The Mühlen CA 400 is a packaging filler machine for businesses that pack orders every day and end up with a steady pile of used boxes: e-commerce warehouses, small and mid-sized manufacturers and wholesalers. Instead of buying in filling material, you feed corrugated board and boxes into the machine and get soft padding for your parcels. With a compact desktop footprint of 580 x 330 x 300 mm, it can stand right beside the packing table.
Key Features and What They Do
- Waste cardboard becomes filler: Used boxes are converted into reusable packaging filler, giving you an alternative to bought-in material and a clear cost advantage.
- 420 mm feed width with automatic trimming: Cardboard up to 420 mm wide goes straight in; anything wider is trimmed automatically, so no manual pre-cutting is needed.
- 550 cm per minute: Filler is produced fast enough to keep up with busy packing hours.
- 800 Watt motor and hardened steel blades: Material up to 12 mm thick is processed without strain.
- Quiet below 55 dB: Suitable for packing areas close to offices.
- Emergency stop and reverse: The red button stops the machine instantly, and the off / forward / reverse switch lets you back out jammed material.
Frequently Asked Questions
How thick can the cardboard be?
The CA 400 handles material up to 12 mm thick, including corrugated board and boxes.
What happens if my cardboard is wider than 420 mm?
The machine trims the excess automatically, so wider sheets can still be fed in.
What should I do if material jams?
Switch to the reverse setting to pull the material back. In an emergency, press the red stop button; turning it returns the machine to the operating position.
What warranty does it come with?
The CA 400 is supplied with a 24 months warranty.
Usage and Care Tips
Place the cardboard into the feed opening and run the machine in the forward setting; the narrow inlet keeps hands and fingers away from the blades. The double-sided scaled ruler helps you line up the sheet before feeding. Keep the blade area free of cardboard dust to protect the hardened steel blades. For transport or storage, the machine fits its wooden crate (680 x 440 x 500 mm).
