| Shanghai Longjiang color box packaging factory · Heidelberg Equipment Expert

Located in Shanghai, we are experts in Longjiang color box packaging factory with multiple German Heidelberg 5-color + inline coating printing lines and Japanese high-grade inks. We routinely achieve 6+ premium processes on a single box—including hot stamping, spot UV, embossing, debossing, and silkscreen—for luxury cosmetics, gourmet food, and high-end gift packaging.

| Rigid Box and Setup Box Technical Specifications

Our rigid boxes feature wrapped construction with 1200-2000gsm greyboard cores and premium outer papers. Setup boxes include magnetic closures, ribbon pulls, and custom foam inserts as standard options, delivering exceptional unboxing experience and product protection for high-value items.

| Value-Added Services Included in Standard Pricing

Design consultation, digital proofing, color matching, and pre-production samples are all included in our standard pricing—no hidden service fees. This comprehensive approach ensures you receive maximum value and peace of mind throughout the entire packaging development process.

| No Delays During Peak Seasons

Unlike many factories that extend lead times during Chinese New Year, Christmas, or Double 11, we maintain standard 7-10 day delivery year-round through strategic capacity planning and dedicated seasonal teams. Your launch dates stay safe regardless of calendar pressure.

| Ideal for Product Variant Testing & Market Trials

Our small batch capability is designed for brands testing multiple variants—different sizes, colors, or designs—with low risk and fast turnaround. Produce 100 pieces of each variant to gather real consumer feedback before committing to full production.

| Color Evaluation Under Multiple Lighting Conditions

Proofs and final products are evaluated under D50 daylight, store lighting, and warm LED conditions to ensure colors appear consistent across different retail environments. This multi-light assessment prevents unpleasant surprises when packaging reaches shelves.

| Mastery of All Standard Printing Processes

We have perfected conventional four-color (CMYK) printing, spot color application, and high-resolution offset techniques to deliver sharp text, vibrant images, and smooth gradients. These core processes form the reliable foundation for all our premium color box production, ensuring consistent quality across every project.

| Reliable Vibration and Transport Simulation Testing

We subject packaging to extended vibration testing on shaker tables simulating truck, air, and sea transport. This ensures contents remain secure and undamaged during long-distance shipping, especially important for fragile cosmetics and glass products.

| Exclusive Specialty and Textured Paper Collection

Our curated collection includes premium textured papers like linen, felt-mark, leather-effect, and pearl shimmer finishes. These specialty substrates add distinctive tactile and visual depth, creating memorable unboxing experiences for luxury beauty and gift brands.

| Zero Mix-Up Guarantee for Complex Orders

Our robust order management system and color-coded production controls eliminate mixing between different SKUs. Every box is tracked from printing to packing, ensuring 100% accuracy even when running dozens of variants side by side.

| Advanced Defect Prevention and Control Tools

We employ statistical process control (SPC), fishbone analysis, and FMEA (Failure Mode Effects Analysis) to identify and eliminate potential defects before they occur. These proactive tools complement our inspection processes for superior quality outcomes.

| Gourmet Food and Premium Chocolate Boxes

We create food-safe, elegant packaging for artisanal chocolates, teas, and specialty foods with inner trays, window patches, and gold foil detailing. These designs protect delicate contents while presenting products as high-end gifts that command premium pricing.
