Rotary Arm Stretch Wrap Machine
What Is a Rotary Arm Stretch Wrapper?
A Rotary Arm Stretch Wrapper is an advanced pallet wrapping machine designed to secure loads using stretch film while keeping the pallet stationary. Instead of rotating the pallet, the machine rotates a mechanical arm around the load, making it ideal for lightweight, tall, fragile, or unstable pallets.
Innovative Mechatronics designs rotary arm stretch wrappers to deliver consistent, high-speed, and damage-free pallet packaging for modern industrial environments.
How Does a Rotary Arm Stretch Wrapper Work?
-
The operator places the pallet in the wrapping zone.
-
The stretch film is attached to the pallet base manually or automatically.
-
The rotary arm starts rotating around the stationary pallet.
-
The film carriage moves up and down to cover the entire load height.
-
The machine applies controlled film tension for uniform wrapping.
-
The wrapping cycle completes automatically, and the pallet is ready for transport.
This process ensures load stability without disturbing fragile or unbalanced products.
Why Is This Machine Important in Modern Industrial Operations?
Modern industries demand speed, consistency, and safety. A rotary arm stretch wrapper:
-
Eliminates load collapse caused by pallet rotation
-
Increases packaging speed and throughput
-
Reduces labor dependency and operator fatigue
-
Saves stretch film through controlled pre-stretch systems
-
Improves workplace safety and packaging quality
Innovative Mechatronics integrates automation and precision to meet these demands efficiently.

Frequently Asked Questions (FAQs)
1. What is a Rotary Arm Stretch Wrapper used for?
A rotary arm stretch wrapper secures palletized loads using stretch film while keeping the pallet stationary, making it ideal for unstable or fragile products.
2. How is a rotary arm wrapper different from a turntable wrapper?
Unlike turntable machines, the rotary arm rotates around the load instead of spinning the pallet, preventing load collapse and product damage.
3. Which industries commonly use rotary arm stretch wrappers?
Industries such as FMCG, pharmaceuticals, chemicals, logistics, paper, and electronics widely use these machines for safe pallet packaging.
4. Is a rotary arm stretch wrapper suitable for heavy or tall pallets?
Yes, since the pallet remains stationary, the machine handles heavy, tall, and lightweight loads without stability issues.
5. Does the machine help reduce stretch film consumption?
Yes, Innovative Mechatronics machines use powered pre-stretch systems that significantly reduce film usage and packaging costs.
6. What level of automation is available in rotary arm stretch wrappers?
These machines are available in semi-automatic and fully automatic models with PLC, HMI, and conveyor integration options.
7. What safety features are included in the machine?
Safety features include emergency stop buttons, safety sensors, optional fencing, and controlled arm movement for operator protection.
8. How can buyers choose the right rotary arm stretch wrapper?
Buyers should consider pallet size, load stability, daily output, automation needs, and budget. Innovative Mechatronics provides expert guidance for model selection.
