S Series Foldable Industrial Boxes – Built for Daily Industrial Logistics
As a professional S Series Foldable Industrial Boxes manufacturer and supplier in China, Suzhou Xinhao Packaging combines lightweight construction with robust performance. Our S Series boxes are designed for the daily rhythm of industrial operations: parts handling, assembly line supply, and in-process storage. They fold flat when empty, reducing return logistics and warehouse footprint, while their modular design integrates with standard shelving, flow racks, and conveyor systems.
We engineer these boxes for repeat use in demanding environments—automotive, electronics, machinery, and general manufacturing. The range supports OEM/ODM customization, so we can match dimensions, colors, logos, and material properties to your specific process.
Product Range and Positioning
The S Series sits within our broader Collapsible Plastic Crate family, which also includes EUO and F Series crates. While EUO crates target standardized European logistics and F Series offers heavy-duty variants, the S Series focuses on versatility and ease of handling for internal and inter-plant logistics.

Application Fit and Material Considerations
The S Series is molded from polypropylene (PP) or high-density polyethylene (HDPE), depending on your load and chemical exposure. PP offers good stiffness and fatigue resistance; HDPE provides superior impact strength at low temperatures. We can also incorporate anti-static or conductive additives for electronics applications, where electrostatic discharge protection is critical.
For automotive and machinery environments, the boxes resist oil, grease, and cutting fluids. Their smooth interior surfaces are easy to clean, reducing contamination risk in precision assembly.
Critical Specifications and Performance
- Load capacity: Typically 20–50 kg, depending on size and configuration. We confirm exact values during proposal preparation.
- Stacking: When loaded, boxes stack securely with integrated stacking lugs; when empty, they fold to a fraction of their height.
- Temperature range: Suitable for most industrial environments, with options for high- or low-temperature grades.
- Dimensions: Standard sizes range from small totes to large crates; custom sizes are available.
Configuration Options and Automation Integration
We configure the S Series around your line interface. Options include:
- Solid or ventilated walls and bases for airflow or drainage.
- Card holders, label slots, or RFID tag pockets for tracking.
- Anti-static or conductive material for electronics.
- Custom colors and molded-in logos for brand identification.
For automated systems, the boxes can be designed with precise external dimensions and smooth surfaces to run on roller conveyors, automated storage and retrieval systems (AS/RS), and robotic handling equipment. We work with your equipment specifications to ensure dimensional tolerances and stacking stability.
Quality Assurance and Acceptance Testing
Our factory is ISO 9001 certified, and we implement five inspection checkpoints from incoming raw materials to finished products. We source resins from reputable suppliers like Sinopec and ExxonMobil to ensure consistency. Each production batch is tested for dimensional accuracy, load capacity, and fold/unfold cycle durability. We can provide test reports upon request.
For custom designs, we produce samples for your approval before mass production. Acceptance testing includes dimensional verification, stacking tests, and visual inspection.
Maintenance, Spare Parts, and Serviceability
S Series boxes are designed for minimal maintenance. They can be washed with standard industrial cleaning agents and are resistant to most solvents. Hinges and latches are molded as integral parts, reducing the risk of breakage. In the unlikely event of damage, we can supply replacement boxes or components for modular systems.
We maintain a warehouse inventory of over 200 tons of raw materials and finished products, ensuring quick replenishment for urgent orders. Our in-house transport team coordinates delivery to meet your schedule.
Documentation and Training
With each order, we provide technical datasheets, material certificates, and handling instructions. For large-scale implementations, our team can offer on-site training for your operators on proper folding, stacking, and cleaning procedures to maximize box lifespan.
Information We Use to Configure Your Solution
To prepare a precise proposal, we need the following details:
- Part dimensions and weight (including packaging weight).
- Required stacking height and load capacity.
- Operating environment (temperature, chemicals, cleanroom).
- Handling method (manual, conveyor, forklift, robotic).
- Desired external dimensions and any racking constraints.
- Quantity and delivery schedule.
- Any special requirements (anti-static, color, logos, RFID).
Frequently Asked Questions
What is the typical lead time for S Series boxes?
For standard sizes, we can ship from stock within days. Custom orders require tooling and sample approval, typically 3–5 weeks depending on complexity. We confirm exact lead times in our quotation.
Can the boxes be used in automated storage systems?
Yes, we can adjust external dimensions and tolerances to suit your AS/RS or conveyor system. Provide us with your equipment specifications, and we will design accordingly.
Do you offer anti-static versions?
Absolutely. We can incorporate anti-static or conductive additives into the material, making the boxes suitable for electronics and ESD-sensitive components.
What is the maximum stacking load?
It depends on the box size and material. Our standard S Series boxes typically support 20–50 kg per box, and stacking loads are calculated based on the number of boxes and racking conditions. We provide exact data in the datasheet.
Can I get samples before placing a bulk order?
Yes, we offer samples for evaluation. For standard models, samples are available at a nominal cost, which is credited back on bulk orders. Custom samples are produced after design approval.
