2. Do you have experience working with global enterprise brands?

Yes. We are the trusted packaging partner for numerous Fortune 500 companies and industry leaders, including Xiaomi, LG, POP MART, Samsung, and Mattel. We are fully equipped to meet strict enterprise-level compliance, supply chain stability, and high-volume demands.

We manufacture to world-class standards. Our facility is certified with ISO 9001, ISO 14001, and the rigorous IATF 16949 (Automotive Standard). For material safety and sustainability, we hold GRS, RCS, RoHS, REACH certifications, and have successfully passed the Disney Facility Audit.

4. How fast can I get a quotation for my custom packaging?

We guarantee a rapid response. Once you share your product details, drawings, or functional requirements, our dedicated engineering team will provide a professional and highly competitive quote within 12 hours.

5. Can I get physical samples before placing a mass order?

Absolutely. We highly recommend physical testing. Our rapid prototyping process takes 3 to 7 days depending on the complexity (mono-layer or laminated). While sampling requires an initial mold/setup fee, this cost can be fully refunded upon confirmation of your mass production order.

6. What is your standard lead time for mass production?

Supported by our robust PMC (Production Material Control) system, our lead times are highly stable. New custom orders generally take 7 to 10 days to complete, while repeat orders can be fulfilled in approximately 1 week. We proudly maintain a 90%+ on-time delivery rate.

7. What level of customization do you offer?

We offer 100% bespoke solutions. You can customize the bag format (stand-up, flat bottom, spout, shaped), the functional structure (anti-static, high-barrier, retort, freezer-grade), and the visual finish (up to 13-color printing, matte, spot UV, holographic).

8. Do you provide sustainable or eco-friendly packaging options?

Yes, sustainability is a core focus. We offer fully Recyclable mono-material structures (PE/PO/CPP) and Biodegradable options (PLA, PBAT). All our eco-friendly solutions are fully traceable under our Global Recycled Standard (GRS) certification.

9. What is your Minimum Order Quantity (MOQ)?

Since all our flexible packaging is engineered to order, the MOQ varies depending on the specific bag dimensions, material structure, and printing requirements. Please contact our sales team with your specifications, and we will work out a flexible solution tailored to your project stage.

10. How do you handle quality issues or after-sales claims?

We maintain a world-class 99.8% product yield rate. However, if any defects occur, we have a transparent claim process. Within the 12 to 18-month warranty period, simply provide batch details and samples. If our lab confirms a manufacturing defect, we will promptly arrange for a free replacement or issue a refund.
