Corrugated Plastic Box with Dividers Manufacturer
Zhejiang Zhapu Plastic Co., Ltd. is a specialized manufacturer of corrugated plastic boxes with dividers, producing compartmentalized containers from polypropylene (PP) hollow board. Our range includes stackable crates with curved slot dividers, ESD compartmentalized containers with grid dividers, and divided hardware sorting boxes. These products serve industries that require organized storage, safe transport, and efficient picking of components, parts, and finished goods.
As a Corrugated Plastic Box with Dividers manufacturer, we combine in-house extrusion, die-cutting, and box assembly to deliver custom sizes, divider configurations, and material grades. Our factory in Zhejiang, China, operates 9 extrusion lines and post-processing equipment, enabling us to control quality from resin to finished box.
Product Range and Application Fit
Our compartmentalized boxes are designed for specific workflow needs. The table below outlines the main types we supply and their typical uses.
| Product Type | Key Features | Typical Applications |
|---|---|---|
| Stackable PP Corrugated Crate with Curved Slot Dividers | Curved slots hold dividers securely; stackable design for vertical storage. | Warehouse storage, assembly line feeding, transport of fragile components. |
| ESD Compartmentalized PP Hollow Board Container with Grid Divider | Anti-static/conductive material; grid dividers create multiple cells. | Electronics manufacturing, PCB handling, cleanroom storage. |
| Divided Coroplast PP Hollow Board Hardware Sorting Box | Rigid construction; removable or fixed dividers; color options. | Hardware inventory, small parts sorting, maintenance kits. |
We also produce custom compartmentalized boxes for specialized uses, such as automotive parts, medical supplies, and agricultural produce. Each box is fabricated from PP hollow board, which is lightweight yet impact-resistant, waterproof, and reusable.
Material and Workpiece Considerations
The base material is polypropylene hollow board, available in standard, anti-static, conductive, and flame-retardant grades. For ESD-sensitive applications, we use conductive or anti-static PP compounds that meet surface resistivity requirements. The board thickness typically ranges from 2 mm to 12 mm, with common choices for boxes being 3 mm to 5 mm for walls and dividers.
When selecting a box, consider the weight and dimensions of the items to be stored. Our dividers can be configured to create cells of varying sizes, and we can add handles, lids, or labels as needed. For heavy loads, we reinforce corners and edges with additional layers or metal trims.
Critical Specifications and Customization
We engineer each box to meet your dimensional, load, and environmental requirements. Key specifications we can adjust include:
- External dimensions: Length, width, and height tailored to your racking, conveyor, or shipping constraints.
- Divider layout: Number of compartments, cell size, and divider height—fixed or removable.
- Material grade: Standard PP, UV-stabilized for outdoor use, or ESD-safe compounds.
- Color: Custom colors for coding or branding, using food-grade pigments.
- Add-ons: Hand holes, stacking lugs, lids, card holders, and anti-slip surfaces.
Our in-house die-cutting and box nailing equipment allows precise fabrication of dividers and box panels. We also operate a water-based ink printing machine for logos, part numbers, or handling instructions directly on the box.
Capacity and Throughput
With 9 extrusion lines and a factory area of 13,333 m², we produce large volumes of PP hollow board and finished boxes. Our production capacity supports both small-batch prototypes and high-volume orders. We manage lead times by coordinating extrusion, cutting, assembly, and printing in-house, reducing external dependencies.
For high-throughput operations, we can supply boxes that are nestable or foldable to minimize return shipping volume. Stackable designs with reinforced corners allow safe stacking in warehouses and during transport.
Quality Assurance and Testing
All products undergo SGS testing, and our quality management system is ISO 9001 certified. We also hold ISO 14001 for environmental management and ISO 45001 for occupational health and safety. Our quality control covers raw material inspection, in-process checks, and final dimensional and visual inspection.
For ESD boxes, we verify surface resistance using standard test methods. For load-bearing boxes, we perform compression and impact tests to ensure they withstand stacking and handling. We provide test reports and certificates upon request.
Integration and Installation Support
Our boxes are designed to integrate with existing material handling systems. We can match dimensions to your shelving, conveyors, or automated storage and retrieval systems (AS/RS). For automated lines, we ensure consistent external dimensions and smooth surfaces to avoid jams.
We provide assembly instructions for knock-down boxes and can supply pre-assembled units if required. Our technical team assists with divider layout optimization to maximize space utilization and picking efficiency.
Maintenance and Serviceability
PP hollow board boxes are easy to clean—simply wash with water or mild detergent. They resist moisture, chemicals, and corrosion, making them suitable for repeated use. Dividers are replaceable, extending the box's life. We offer spare dividers and replacement parts for standard models.
For long-term programs, we can establish a replenishment schedule to ensure you have spare boxes and dividers when needed. Our after-sales team responds online 24/7 to address any issues.
Documentation and Training
Each order includes packing lists and, if requested, material safety data sheets (MSDS) and test certificates. For large projects, we provide product drawings and quality documentation. We can also supply user guides for assembly and maintenance.
Information We Use to Configure Your Solution
To prepare a precise proposal, please provide the following details:
- Internal and external dimensions of the box
- Number and size of compartments required
- Type of items to be stored and maximum load weight
- Material grade (standard, ESD, flame-retardant) and color
- Stacking or nesting requirements
- Accessories such as lids, handles, or labels
- Estimated annual quantity and delivery schedule
With this information, we can provide a tailored quotation and sample for approval before mass production.
FAQs
What is the minimum order quantity for custom boxes with dividers?
We accommodate both small and large orders. For custom sizes and printing, a minimum quantity may apply, but we can discuss based on your project needs. We often produce samples first for approval.
Can you provide ESD-safe boxes for electronics?
Yes, we offer anti-static and conductive PP materials that meet ESD requirements. Our ESD compartmentalized containers are designed for safe handling of sensitive electronic components.
How do I determine the right divider configuration?
Consider the size and quantity of items you need to store. We can help you design a layout that maximizes space and accessibility. Send us your item dimensions and we will propose a cell arrangement.
Are your boxes reusable and recyclable?
Yes, our PP boxes are durable and can be reused many times. They are also 100% recyclable, and we hold GRS certification for recycled content options.
What is the typical lead time?
Lead time depends on order complexity and volume. For standard boxes, we can often ship within 2-3 weeks after confirmation. Custom orders may take longer due to tooling and printing setup.
