How We Deliver Your Custom Packaging Project？
A clear, step-by-step service process
Requirement Consultation
01
We start with a detailed consultation to fully understand your packaging needs. This includes your product specifications, target market, budget range, branding requirements, sustainability preferences, and delivery timelines. Our team will also review any existing packaging samples, reference designs, or technical constraints to ensure nothing is overlooked.
Outcome: A clear, documented brief that aligns expectations before moving forward.
Packaging Solution Planning
02
Based on your requirements, we develop a tailored packaging solution that balances design, functionality, cost, and manufacturability. This stage covers material selection, box structure, printing methods, finishing options, and logistics considerations. We also provide professional recommendations to optimise durability, shelf impact, and cost efficiency.
Outcome: A proposed packaging plan with clear specifications and cost structure.
Custom Sampling & Prototyping

Before mass production, we produce a custom sample for your review and approval. This allows you to assess the structure, materials, print quality, colours, and finishes in real life. Feedback and revisions are welcomed at this stage to ensure the final product meets your expectations.
Outcome: An approved physical sample that serves as the production benchmark.
Mass Production

Once the sample is approved and the initial payment is confirmed, we commence mass production. Manufacturing is carried out by vetted factories with strict quality control standards. Throughout production, we monitor timelines, print consistency, and material quality to minimise risks and delays.
Outcome: High-quality packaging produced at scale, on schedule.
Quality Inspection & Delivery
05
All finished products undergo quality inspection before shipment to ensure they match the approved sample and agreed specifications. After inspection and the final payment, we coordinate secure packaging, logistics and custom clearance to deliver your order safely to the designated location.

Frequently Asked Questions
Single wall boxes are made from one layer of corrugated cardboard, while double wall boxes have two layers of corrugated cardboard. Double wall boxes offer more strength and durability compared to single wall boxes.
For heavy or fragile items, double wall boxes are recommended as they provide better protection due to their extra layer of corrugated cardboard. Single wall boxes may not be able to withstand the weight or impact as effectively.
Consider the weight, fragility, and value of your products when choosing between single wall and double wall boxes. If your items require extra protection or are heavy, opt for double wall boxes. For lighter or less fragile items, single wall boxes may be sufficient. We will help you assess your specific packaging needs, so you can determine which kind of box will work best.
