What is SPC?
Stone Polymer Composite (SPC) is a mineral-filled polymer composite material engineered for packaging applications.
Here, SPC means Stone Polymer Composite — not Stone Plastic Composite flooring.
Mineral particles are incorporated into a polymer matrix to create a composite material suitable for extrusion into thin, hollow packaging board.

Why composite packaging
Built around how goods are actually handled.
Wet, cold, stacked and handled again and again — packaging has to keep up. SPC hollow board gives us a material we can engineer around those conditions.
Moisture-oriented design
For packaging exposed to humidity, condensation and wet handling.
Structural packaging
Board thickness, internal ribs and box structure can be developed around the load and the application.
Cold-chain development
Packaging can be evaluated for refrigerated or frozen logistics requirements.
Custom converting
Ventilation, drainage, partitions, pads and printing can be incorporated into box development.
Repeat-handling potential
Structures may be developed for applications that require repeated handling.
Transport durability
Box structures are developed with stacking and transport handling in mind.
Applications
Where SPC packaging fits.
We focus on a small number of demanding applications rather than every packaging market.
Fresh produce
Ventilated boxes and trays for fruit and vegetables.
Cold chain
Packaging developed for chilled and wet-environment logistics.
Seafood
Moisture-oriented packaging for wet, chilled seafood distribution.
Food & beverage
Divided boxes and pads for bottled and packaged products.
Industrial logistics
Reusable transit packaging for parts and components.
Electronics
Protective separation and compartments for precision parts.
Future material applications
Tracked separately: flooring, furniture panels, decorative panels and other building-material products.
Products
Seven packaging lines, one material platform.
Each line starts from the same SPC hollow board and is developed around a specific application.
SPC Corrugated Hollow Sheet
Thin twin-wall mineral-polymer sheet — the base material for every box.

ViewSPC vs corrugated cartons
A fair comparison for the same packaging job.
Material, structure and purchase conditions decide the result. We compare SPC hollow-board packaging against a specific corrugated carton for the same inner size, load and route — never against a straw man.
| SPC hollow board | Corrugated carton | |
|---|---|---|
| Material | Mineral-filled polymer composite, thin twin-wall hollow board. | Paper-based corrugated board, fluted core between liners. |
| Moisture | Not paper-based; sustained-moisture behaviour validated per application. | Strength typically falls when wet unless coated or waxed. |
| Repeated handling | Structures can be developed for more than one trip. | Usually single-trip unless specially treated. |
| Cost basis | Evaluated per project against the target box and order size. | Mature supply chain, transparent pricing by grade and volume. |
Compared for the same effective inner size, single box load, stacking and transport route.
We do not claim SPC packaging replaces corrugated cartons everywhere, is stronger in all conditions or is always cheaper — the comparison must fit your exact job.
Cost evaluation
Packaging developed around your required function and target cost.
We evaluate cost against the same packaging job you have today — not against a generic box. Start from what your box must do, then compare on that basis.
- Same effective inner size, load per box and stacking
- Same environment: wet, chilled, frozen or ambient
- Single-trip or repeated-use comparison, stated clearly
- Your order size, delivery market and timing
- Structure options that meet the function first, then cost
A concrete cost comparison needs your current box, its specification and your volume. We do not publish savings ratios without that basis.

Sample & engineering
Send us your existing packaging or specification.
Engineering review comes before prototyping. The more we know about your box and how it is handled, the better the first sample.
- Existing box or drawing
- Inner or outer dimensions
- Product load per box
- Temperature environment
- Stacking and handling
- Printing and accessories

Technology
From mineral and polymer to finished box.
A short preview of the technology behind SPC packaging. Process details stay at the level a buyer needs — not a recipe.
Stone Polymer Composite
A mineral-filled polymer composite material engineered for packaging.
What is SPCCompounding
Mineral, polymer and functional additives are combined into a consistent composite compound.
Hollow board structure
Thin outer skins joined by internal ribs form a light, hollow twin-wall packaging sheet.
Printing
Basic colour printing on the board surface for identification and branding.
Converting
Cut, die-cut, punch, fold, weld and assemble — board becomes a box.
Production & converting
A manufacturing model built for prototype-to-production.
Our manufacturing model is being developed around SPC board production, printing and converting for commercial applications.
Small batches and trial orders come first. The process model below describes how board becomes finished packaging; it is a process model, not a claim of current capacity.

Frequently asked questions
- What does SPC mean at CSBX?
- Stone Polymer Composite — a mineral-filled polymer composite material engineered for packaging.
- Is SPC the same as SPC flooring?
- No. CSBX uses SPC to describe Stone Polymer Composite packaging material. It is not Stone Plastic Composite flooring.
- Can I submit an existing box for evaluation?
- Yes. Customers can submit packaging requirements and drawings through the sample request process.
- Can packaging structures be customised?
- Packaging structures can be developed around dimensions, loading, handling and application requirements.
- Do you offer global delivery?
- Delivery terms are confirmed per project and order.
