About Us
A Chinese Packaging Supplier with Manufacturing Behind It
CosunPack is a Chinese packaging supplier serving global brands since 2008. We combine one-stop packaging development with full-range sourcing. Our Guangzhou paper and flexible printing workshops and equity-partnered plastic, glass, and metal container facilities work through one coordinated engineering and QC team.
Our Manufacturing Architecture
Our Guangzhou flagship handles paper printing, folding cartons, corrugated converting, rigid gift boxes, and high-barrier flexible packaging. In-house printing and converting keep these core processes close to our engineering and production planning teams.
Plastic, glass, and metal containers are manufactured at specialized equity-partnered facilities across the Pearl River Delta. Dedicated line capacity gives each material the equipment and process expertise it needs, coordinated through our Guangzhou headquarters.
Start with your product, reference sample, or packaging brief. Our team helps develop structures and materials, coordinate component fit and samples, and carry approved specifications into production and quality checks. Printed packaging and containers can then be consolidated at our Guangzhou hub for agreed global delivery.

Why Coordinated Manufacturing Reduces Sourcing Cost
Our in-house printing and equity-partnered container lines share procurement, engineering, QC, and shipment planning. Compare the complete project cost, including tooling and logistics.

| Pricing | Separate material purchases and supplier quotations | Group purchasing and an itemized factory quotation |
| Engineering | Box, insert, and bottle developed to separate drawings | One coordinated specification with component fit checks |
| Quality access | Different inspection standards and reports at each supplier | Unified IQC, IPQC, and OQC requirements across production sites |
| Brand consistency | Separate proofs for each material and supplier | Coordinated color targets with material-specific approval tolerances |
| Delivery | Multiple pickups, schedules, and logistics charges | Consolidation at our Guangzhou hub with agreed shipping terms |

How We Work
One team for packaging development, full-range sourcing, and coordinated production—from your initial product brief to delivery.
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 review repeat-order specifications, material choices, and production planning with your sourcing team.
Continuous Improvement
We use sample reviews, inspection findings, and buyer feedback to identify improvements for future orders.
Start With a Clear Packaging Brief
Start with what you have—a product, a reference sample, or a finished brief. We help clarify the packaging requirements and development scope.
Product & Protection
Share the product dimensions, weight, fragility, and any barrier or contact requirements. Photos and reference samples help explain the use conditions.
Brand & Presentation
Provide artwork status, color references, preferred finishes, and the packaging components that need to work together.
Volume & Delivery
List the quantity per SKU, target launch date, destination, and preferred shipping terms. Tell us which requirements are flexible.
One Partner for Your Complete Packaging
Source packaging from China with one team, from product-led development to delivery. Share your product or idea, component list, quantity, and destination—we will help define the next steps.
