1. 2-in-1 High Efficiency
Combines automatic stretch wrapping and full-automatic strapping in one seamless process. Doubles packaging efficiency while reducing floor space and labor costs.
2. Dual Reinforcement Safety
Features film wrapping + strapping double protection. The film provides comprehensive coverage, while the strap locks down the load. Ensures cargo stability even for heavy, tall, or unstable loads during long-distance shipping.
3. Intelligent & Easy Control
Equipped with PLC + HMI touch screen for one-touch operation. Precisely set wrapping layers, strapping points, and tension. Automatic film feeding, cutting, and strap feeding eliminate manual intervention.
4. Wide Adaptability
Supports both PP/PET straps and various stretch films. Flexibly switch between different packaging specifications. Handles pallets of various sizes, weights, and special shapes, meeting diverse packaging needs across industries.
5. Cost-Effective & Stable
Features a power pre-stretch film carriage (up to 300% stretch ratio) to significantly reduce film consumption. Chain-driven lifting ensures stable, low-noise operation for lower long-term operational costs.
This integrated film wrapping and strapping machine combines automatic stretch film wrapping with full-automatic PET/PP strapping in one operation. It completes dual reinforcement efficiently with less labor, adopts intelligent PLC control to freely set wrapping layers, strapping times and tension. Suitable for pallet goods in logistics, building materials, chemical and other industries, it features stable performance and easy operation to realize integrated, standardized and automatic packaging.

FAQ:
Why does stretch film easily break when wrapping?
There are three common reasons: (1) the tension of the stretch film is set too high; (2) the film is thin, brittle, or damaged; (3) the film carriage or roller is stuck, causing uneven force. The solutions are to appropriately reduce the tension, use high-quality stretch film, and clean the guide rollers.
What should I do if the goods in the package are loose?
(1) Increase the stretch ratio of the film to achieve tighter packaging; (2) Slow down the hoist speed of the rack to improve film overlap; (3) Check if the pre-stretch mechanism is working properly without slipping; (4) Wrap 2–3 more layers at the bottom of the goods to better secure them.
Why does the turntable not rotate or run slowly after starting?
First, check whether the emergency stop button has been reset and whether the inverter parameters have been incorrectly adjusted. Then check if the chain or belt is loose or slipping, and whether the motor is abnormal. Low-speed force is usually caused by a low inverter current setting or the brake not being released; readjust the parameters to correct it.
How to deal with increased noise after long-term use?
The main reasons are insufficient lubrication or loose parts. (1) Lubricate the turntable bearings, chains, and gears; (2) Tighten loose screws, film holders, and covers; (3) Clean debris under the turntable to avoid friction noise. Regular maintenance can greatly reduce noise.
