Certified OEM Printing Facility for Custom Packaging Boxes
SunTop provides OEM custom packaging boxes manufactured with paperboard and cardstock folding box structures, designed for commercial packaging programs that require structural consistency and repeat execution.
Projects are executed under a single in-house system covering printing, finishing, assembly, and export logistics to support predictable replenishment cycles.
DDP landed delivery is available for the United States, Canada, and Australia, with customs clearance and final-mile coordination managed under one workflow.
SunTop operates a fully in-house OEM production facility in Shenzhen, focused on paperboard and cardstock folding box manufacturing for commercial packaging programs.
Our production system supports:
-
First production runs for new SKUs
-
Ongoing replenishment for established product lines
-
Multi-SKU programs requiring consistent structure and color alignment
All packaging is produced under G7® color management and ISO 12647 print process control, using FSC®-certified paperboard materials where required.
For brands distributing products into the United States, Canada, and Australia, projects can be executed with DDP door-to-door delivery, consolidating production and logistics under a single accountable system.
Commercial Packaging Scope & Use Context
This page is designed for commercial packaging projects, where structural consistency and repeat execution matter more than one-off production.
Typical project characteristics include:
-
Commercial-level production volumes
-
Packaging aligned with retail shelving, e-commerce fulfillment, or subscription distribution
-
Materials and finishes selected to match brand positioning rather than lowest cost
Custom packaging boxes produced here are commonly applied when:
-
Product SKUs must remain visually consistent across multiple runs
-
Warehousing and packing efficiency is part of the packaging design
-
Brand presentation and structural reliability are both required
Typical application programs include:
-
Skincare and personal care packaging
-
Nutraceutical and regulated dietary supplement packaging
-
Consumer electronics and accessory packaging
-
Multi-SKU retail and subscription programs
In limited presentation-focused cases, rigid formats may be included within a broader custom packaging program and are not treated as the primary packaging structure.
This page is not intended for one-off sample requests, personal projects, or price-only inquiries without defined production intent.
