Frequently Asked Questions

Answers to the questions we hear most from global buyers and brand managers.

How do you ensure your pouches are perfectly compatible with our automated packaging machines? +
Our engineering team coordinates directly with your technical staff prior to production -- verifying coefficient of friction (COF), heat seal temperature range, and eye-mark positioning on roll film or pre-made pouches. We provide dedicated process matching for all major automated filling lines, including Bossar, Volpak, and other leading equipment brands.
What is the lead time for bulk custom orders? +
Once artwork is confirmed and plate fees are settled, first-run gravure production typically takes 15-20 business days. Repeat orders (reorders) skip the plate-making step, reducing lead time to 10-12 days. We are fully committed to keeping established brand clients' supply chains uninterrupted.
Can we get free samples to evaluate your printing quality and material performance? +
Absolutely. We're happy to send you a Free Stock Sample Kit featuring a curated selection of our surface finishes (matte, spot UV, hot foil stamping) and material structures. You can personally evaluate the tactile feel, print clarity, and puncture resistance before committing to a production run.
What certifications does your factory hold? +
We hold ISO 9001 Quality Management, BSCI Social Responsibility, BRC/SGS Global Food Packaging Standard, FDA Food Contact Material, and HALAL certifications -- covering the full spectrum of global market compliance requirements.
What is the minimum order quantity (MOQ)? +
MOQ varies by product type, material structure, and printing complexity. Please submit your requirements via the inquiry form below and our product engineers will provide a specific MOQ and competitive ex-factory pricing within 24 hours.
