Automatic Strapping Machine Manufacturers, Factory

Shanghai We Pack Co., Ltd. supplies the Automatic Strapping Machine range as one part of a complete cargo securing and transport protection portfolio. Founded in 2019 as a subsidiary of Shanghai Dreammao Packaging Technology Co., Ltd., we manufacture from a 10,000 m² facility in Fengxian District, Shanghai, with 120 employees, 9 production lines and dedicated R&D, testing and quality control teams. As an Automatic Strapping Machine manufacturer in China, we configure the machine together with the strap, buckles and protective materials that run through it, so a packaging line is specified as one system rather than a machine plus unrelated consumables.

The equipment sits inside a wider programme: dunnage bags, paper corner protectors, slip sheets, stretch film, packing strap and the tools that apply them. That matters at the specification stage, because strap tension, seal quality and package protection are decided by the combination, not by the strapper alone.

What the Automatic Strapping Machine Range Covers

The MH-101A Automatic Strapping Machine is a high-speed, programmable system for fully autonomous strap application in production and packaging lines. It runs the complete cycle — strap feeding, tensioning, sealing by heat weld or clip, and cutting — around a package or bundle, with a photo eye that detects the package and starts the cycle without an operator at the pedal. It suits uniform box sizes and palletized or bundled goods in publishing, food and beverage, distribution and logistics operations.

Fully automatic cycle: feed, tension, seal and cut
Photo-eye package detection for hands-free triggering
Heat-weld or clip sealing, matched to the strap in use
Programmable operation for repeatable bundle tightness
Consistent cycle timing where manual strapping has become the bottleneck

The Packaging Tool Range Around the Strapper

Strapping rarely stands alone. Our Packaging Tool range covers the machines and hand tools that sit upstream and downstream of the strapping position, so a line can be equipped from one supply base.

Equipment	Function in the packaging line	Typical application fit
Automatic Strapping Machine	Fully automatic strap feed, tension, seal and cut with photo-eye triggering	Uniform cartons, bundles and palletized goods on production or packaging lines
Automatic Carton Sealer	Closes carton flaps ahead of strapping so the strap lands on a stable face	Case packing, e-commerce and distribution lines
Electric Strapping Machine	Powered tensioning and sealing at higher-volume manual or semi-automatic stations	Heavy cartons, brick, metal and wood products
Pneumatic Strapping Machine	Air-driven tensioning and sealing where a compressed air supply is available	Steel, aluminium and heavy industrial bundles
Manual Fiber Strap Tensioner	Hand tool for fibre and composite strap	Low-volume bundling, site work and maintenance
PP/PET Strap Dispenser	Holds and feeds strap reels to the machine or workstation	Continuous operation without reel handling at the strapping position
Long-handled Unpacking Scissor	Cuts strap at a safe distance during unpacking	Receiving, deconsolidation and returns handling

Where the Machine Fits in the Packaging Line

Placement decides performance. A strapper is normally positioned after carton sealing and before palletizing, so cartons arrive square and the strap lands on a closed, stable face. Where goods are bundled rather than cased — printed matter, folded cartons, stacked sheet — the machine works as a standalone bundling station fed by a roller table.

We look at the line as a sequence: infeed conveyor, package orientation, strapping position, outfeed and accumulation. If the line already includes a carton sealer or a strap dispenser, we match the strapper to the same conveyor height and control handshake so the modules behave as one line rather than three separate machines.

Strap and Consumable Matching

Strap choice sets the tension window, the seal method and the cost per bundle. PP, PET and composite straps behave differently under the same machine settings, so we select the strap first and then set the machine around it.

Strap	Application fit	What it means for machine setup
PP Packing Strap	Light to medium cartons, bundling of printed matter and consumer goods	Lower tension window, heat-weld sealing, economical per-metre cost
PET Packing Strap	Heavier cartons, brick and tile, metal and wood products, loads needing retained tension	Higher tension setting; seal quality and blade condition carry more weight
Composite Strap	Heavy or irregular loads, timber, pipe and coil bundling	Wider strap path; tension and seal verified against the load

Critical Specifications That Define the Working Point

Every proposal is built from the working point rather than a catalogue number. These are the values that decide arch size, strap path, cycle timing and sealing method.

Package dimensions: minimum and maximum length, width and height, and the variation between them
Package weight range and load stability
Strap material, width and thickness
Number and position of straps per package — single, double, cross or edge
Required throughput, expressed as packages per minute or per shift
Sealing method: heat weld or clip
Conveyor height, direction of travel and package orientation
Available power supply and compressed air at the installation point
Control interface: standalone, foot switch, or PLC handshake with the line

Configuration, Safety and Line Integration

We configure the control system around the required line interface. A standalone machine runs from its own panel and photo eye; a line-integrated unit takes a start signal from the upstream conveyor and returns a cycle-complete signal downstream.

Arch and strap path sized to the largest package in the run
Infeed and outfeed roller or belt conveyors matched to existing line height
Photo-eye position set for the package length and gap pattern
Strap dispenser mounted for reel change without stopping the line
OEM / ODM build for distributors and equipment integrators who need their own branding

Safety and installation conditions

Strapping machines combine moving strap paths, heated sealing elements and sharp cutting blades, so guarding and access are part of the specification rather than an afterthought.

Fixed guarding around the strap path with interlocked access for reel change and jam clearing
Emergency stop within reach of the operator position
Supply voltage and frequency confirmed before shipment
Compressed air supply where pneumatic tensioning or sealing is used
Level floor and clearance for reel loading and maintenance access
Blade and heater replacement carried out with the machine isolated

Quality Assurance and Acceptance Testing

Our quality system runs from raw material to finished goods, supported by an in-house laboratory, testing equipment and third-party verification through SGS and TUV. Management is certified to ISO 9001, and our cargo securing products are tested against AAR, SGS, TUV and other international transport standards.

For strapping equipment, acceptance is a run on your own packages. We strap sample cartons at the intended tension, check seal integrity and strap position, time the cycle across a realistic batch, and confirm the machine holds its settings through a continuous run. Where the strap is supplied with the machine, the same batch is used for both, so tension and seal results reflect the actual consumable rather than a laboratory substitute.

Documentation, Spare Parts and Service

Machines ship with an operation and maintenance manual, a spare parts list and a wiring reference for the installed configuration. Wear items — blades, heaters, belts and strap-path guides — are identified in the parts list so they can be stocked locally and replaced without guesswork.

Our after-sales team supports installation questions, setting adjustments and fault diagnosis remotely, with online response across the working day. Consumables come from the same production base as the machine, which keeps strap dimensions and machine settings aligned over repeat orders. Equipment leaves our Shanghai factory packed for export, close to Shanghai Port and Pudong International Airport.

Frequently Asked Questions

What package sizes can an automatic strapping machine handle?

Arch size and strap path are set from the largest and smallest package in the run. Give us the full dimension range rather than a single size — the machine is configured around that range, and the variation between smallest and largest package determines whether one arch covers the whole run or the line needs a different arrangement.

Can the same machine run PP and PET strap?

Yes, but not at the same settings. PP and PET have different tensile behaviour and seal characteristics, so tension, sealing temperature or clip size are set for the strap in use. We confirm the strap first and then set the machine around it, which is why the strap recommendation and the machine configuration are prepared together.

How does the machine integrate with an existing conveyor line?

We match conveyor height, direction of travel and package orientation, and configure the control interface for the line. A standalone unit runs from its own panel and photo eye; a line-integrated unit takes a start signal from the upstream conveyor and returns a cycle-complete signal downstream. Photo-eye position is set for your package length and gap pattern.

What is the minimum order quantity for a customized machine?

Our minimum order quantity is 100 pieces, which covers trial orders as well as volume supply, and we support OEM / ODM builds for distributors and equipment integrators. Customization covers size, load capacity, materials and printing, developed from your drawings or samples.

What testing and certification applies to your packaging products?

Our management system is certified to ISO 9001, and our cargo securing products are tested to AAR, SGS, TUV and other international transport standards, with in-house laboratory testing and third-party verification. For strapping equipment, acceptance testing is carried out on your own packages so tension, seal and cycle results reflect real production conditions.

How is the machine delivered and supported after installation?

Machines are packed for export and shipped from Shanghai, close to Shanghai Port and Pudong International Airport. Documentation includes the operation and maintenance manual, spare parts list and wiring reference, and our team supports installation questions and setting adjustments remotely. Replacement strap and wear parts are supplied from the same production base as the machine.
