Corrugated Plastic Divider — Custom PP Partition Inserts for Protective Packaging
PPBOXY’s Corrugated Plastic Dividers are precision-engineered partition inserts that transform any shipping box or container into a secure, organized protective packaging system. Manufactured from high-strength PP中空板 — also known as Correx, Coroplast, or Corflute depending on your region — our dividers combine lightweight construction with exceptional impact resistance to protect your products during transit, storage, and handling.
Whether you’re shipping delicate electronics, fragile glassware, precision-machined industrial parts, or sterile medical devices, our custom-fit dividers eliminate product-on-product contact — the leading cause of transit damage. Made to your exact specifications: any shape, any size, any configuration. Factory-direct from PPBOXY.

Key Features of Corrugated Plastic Dividers
Custom-Fit Protection — Any Shape, Any Size
Unlike off-the-shelf packaging inserts that force you to compromise on fit, our corrugated plastic dividers are manufactured to your exact specifications. Provide us with your product dimensions, container dimensions, or a CAD file — and we’ll produce dividers that cradle every item with precision. Complex contours, unusual shapes, tight tolerances — all achievable with PP corrugated sheet technology.
Waterproof, Moisture-Proof & Reusable
Cardboard dividers work once. In humidity, they warp. With liquid contact, they disintegrate. Our PP hollow board dividers are naturally waterproof — they maintain structural integrity through rain, condensation, and temperature swings. And unlike single-use cardboard, PP dividers can be reused dozens of times before recycling, dramatically lowering your per-shipment packaging cost.
Lightweight Yet Structurally Strong
The hollow-flute structure of corrugated polypropylene delivers an exceptional strength-to-weight ratio. Our dividers weigh approximately 60% less than equivalent wood partitions while providing comparable impact protection. This means lower shipping costs, easier handling, and reduced workplace injury risk — without compromising on product safety.
Anti-Static & ESD-Safe Options
For electronics, semiconductors, and precision instruments, static discharge can be catastrophic. Our anti-static (ESD-safe) grade PP dividers feature controlled surface resistivity (10⁶–10⁹ Ω) that safely dissipates static charges — protecting sensitive components from electrostatic damage during transit and handling.
Brand-Ready Surface — Print Your Logo
The smooth, matte surface of PP hollow board is an excellent printing substrate. Add your company logo, product codes, handling instructions, or QR codes directly to each divider — turning functional packaging into a brand touchpoint. Screen printing and hot-stamping available in single or multi-color.

Industry Applications
Electronics & Semiconductor Packaging
Static-sensitive components demand ESD-safe packaging. Our anti-static grade PP dividers protect circuit boards, semiconductors, sensors, and precision electronics from both physical impact and electrostatic discharge. Custom-fitted slots and compartments keep components separated and organized — critical for PCB assemblies and electronic sub-components. For complete protective packaging, see our PP corrugated protectors.
Glassware & Fragile Goods Shipping
Glass-to-glass contact is the #1 cause of breakage in transit. Our custom-fit dividers create individual compartments for each bottle, glass, or fragile item — eliminating contact and absorbing shock. Combined with a correx fragile delivery box, you get a complete protective packaging system that dramatically reduces breakage rates.
Industrial Parts & Automotive Components
Machined metal parts, bearings, gears, and automotive components require dividers that can handle weight and prevent surface damage. Our thicker-grade PP dividers (6mm–12mm) provide the structural strength needed for heavy industrial parts, while the smooth surface prevents scratches and abrasion on precision-finished surfaces.
Medical Device & Pharmaceutical Packaging
Cleanliness and sterility are non-negotiable. Our food-grade and medical-grade PP dividers meet strict hygiene requirements, with dust-free surfaces and full traceability. Custom compartment designs keep sterile instruments, vials, and devices separated and protected. Explore our full 医疗包装 solutions.

Slot & Groove Design for Secure Fit
Our engineering team designs slot-and-groove systems that allow dividers to interlock securely — no adhesives, no fasteners. This creates rigid grid structures that stay in place even when the outer box is handled roughly. Custom groove depths and positions ensure the right balance of rigidity and ease of assembly.

常见问题解答
Q: What thicknesses of corrugated plastic dividers does PPBOXY offer?
We manufacture dividers in 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, and 12mm thicknesses. For most protective packaging, 3mm–5mm provides an excellent balance of strength and weight. Heavier industrial parts may require 6mm–12mm. Contact us for a material recommendation based on your application.
Q: Can you produce dividers in custom shapes — not just rectangles?
Absolutely. We can die-cut dividers to virtually any 2D outline — circles, curves, contours, and fully custom shapes matched to your product geometry. Provide a drawing, CAD file, or sample product, and we’ll engineer the perfect fit.
Q: Are these dividers also known as Correx or Coroplast dividers?
Yes. “Correx” is the common term in the UK and Europe, “Coroplast” in the US and Canada, and “Corflute” in Australia and New Zealand. These all refer to the same corrugated polypropylene material we use. Whatever term your market uses, we manufacture to the same high standard.
Q: What’s the minimum order quantity (MOQ)?
We’re flexible—there’s no fixed minimum. Whether you’re starting with a handful of samples or scaling up to mass production, we’ll customize our service to fit your volume needs.
Q: Can I get anti-static dividers for electronics packaging?
Yes. Our ESD-safe grade features surface resistivity of 10⁶–10⁹ Ω, providing safe static dissipation for sensitive electronics, semiconductors, and PCB assemblies. Available in pink (standard anti-static) or black (conductive) upon request.
Q: How do PP corrugated dividers compare to cardboard dividers in cost?
Cardboard dividers have a lower upfront unit cost — but they’re single-use. Our PP dividers can be reused dozens of times, making the per-use cost significantly lower over time. When you factor in reduced product damage, brand presentation, and waste disposal savings, PP dividers typically deliver positive ROI within 6–12 months.
Q: Can the dividers be printed with our logo?
Yes. Screen printing and hot stamping are available in single or multiple colors. The smooth PP surface delivers excellent print quality — your logo, product information, handling instructions, or QR codes come out crisp and professional.
Q: What is your typical production lead time?
Standard dividers without printing ship in 7–15 business days. Custom die-cut or printed designs require 15–25 business days. Rush orders can often be accommodated — please inquire.
