About Us
The Factory Behind 80+ Brands' Packaging
CosunPack is a Guangzhou-based custom packaging manufacturer serving global B2B buyers since 2008—one partner across paper, flexible, and rigid packaging.
From One Corrugated Line to a Full-Range Packaging Partner
CosunPack started in 2008 with a single corrugated converting line and a simple promise: deliver exactly what the specification says. That promise won us our first export clients—and most of them are still with us today.
Over nearly two decades we grew with our buyers: folding cartons for retail, high-barrier pouches for food, rigid boxes for premium gifting, and eventually glass, plastic, and metal containers—so sourcing teams can consolidate suppliers instead of juggling ten.
Today our export team works exclusively in English with B2B buyers across 80+ countries, supporting everything from a 5,000-piece trial run to ongoing replenishment programs with fixed specifications.

What Factory-Direct Actually Means for You
“Factory direct” gets thrown around a lot. Here is the concrete difference sourcing teams feel after moving their packaging program to the factory floor.
| Dimension | Through a Middleman | With CosunPack |
|---|---|---|
| Pricing | Layered margins stacked on top of the factory price | Ex-works pricing with a transparent cost breakdown |
| Communication | Messages relayed through a middleman | Direct line to the engineer running your order |
| Quality access | Visits and inspections at the intermediary’s discretion | Visit, video tour, or third-party inspection at any stage |
| Customization | Limited to the catalog the intermediary carries | In-house engineering for structure, material, and finish |
| Accountability | Two parties to negotiate with when issues arise | One partner that owns the result end to end |

How We Work
Four principles our long-term buyers would quote back to you.
Specification-Driven
Every commitment is written down—materials, colors, dimensions, finish—so expectations are documented, not assumed.
Straight Talk
If a deadline is risky or a structure has a weakness, you hear it from us early—not after production.
Long-Term Partnership
We price for repeat business, not one-off orders. Most of our revenue comes from buyers who came back.
Continuous Improvement
Structures, materials, and processes are reviewed every quarter with feedback from your market.
What Buyers Say
Long-term partnerships built on clear communication, consistent quality, and quotes you can plan around.
“CosunPack redesigned our coffee pouches with a better barrier structure. Shelf-life complaints dropped to almost zero, and the print quality is the best we have sourced in years.”
