Fully self-produced supply chain, no outsourcing
Our Special Use Food Our bags are manufactured entirely in an integrated workshop, encompassing raw material lamination, gravure printing, bag making, and post-processing. Most small and medium-sized OEMs on the market only handle bag making, outsourcing printing and lamination, leading to frequent issues like color differences, delamination, and uncontrolled delivery times. We have our own dust-free lamination workshop, a 10-color high-speed printing press, and a fully automated bag-making production line, ensuring consistent quality control throughout the process, resulting in stable and uniform thickness and lamination strength.
Customized material solutions, rejecting one-size-fits-all materials
Ordinary factories only recommend generic aluminum foil bags; our R&D team calculates barrier parameters one-to-one based on the customer's food moisture content, oil content, storage temperature, and target shelf life, precisely matching the lowest-cost, optimal material structure to avoid customers overusing materials, increasing costs, or using insufficient materials, leading to food spoilage.
One-stop delivery of complete export compliance qualifications
Small factories on the market can only provide basic testing reports; we possess a full set of qualifications: SC Food Production License, ISO9001, ISO22000 Food Safety, BRCGS, FDA, EU Food Contact Certification, SGS Migration Testing, and Carbon Footprint Report. Exports to Europe, America, Southeast Asia, and the Middle East do not require additional third-party testing from our clients.
Simultaneous development in both paper and plastic composite packaging
Most manufacturers only produce pure plastic flexible bags, with weak capacity in kraft paper composites and laminated paper specialty packaging; our factory started with paper-plastic composites, possessing mature paper + plastic composite technology. Our high-end paper specialty food packaging offers superior texture, oil and moisture resistance compared to our competitors who only produce plastic bags.
After-Sales Team Configuration
We have a dedicated after-sales department divided into four groups: dedicated customer order follow-up, technical after-sales, logistics and customs clearance after-sales, and overseas customer complaint specialists. Each buyer is assigned a one-on-one, lifelong dedicated account manager, without sharing sales liaisons. Ordinary OEM factories often have sales staff handling after-sales as well, with one person handling dozens of customers, resulting in a serious backlog of issues.
Strict Response Time Standards
1. Online emails/WhatsApp/inquiries: 24/7 responsiveness to serve you throughout the process.
2. Product technical parameters, materials, and certification inquiries: Sending a complete technical data sheet + corresponding test report within 30 minutes.
3. Complaints about sampling anomalies, printing color differences, and sealing issues: Technical engineers intervene and analyze within 2 hours, and provide a solution within 4 hours.
4. Bulk Order Production Anomalies and Delay Warnings: Proactive adjustments and compensation plans are provided 3 days in advance.
Production and Quality Control
12,000㎡ Class 100,000 cleanroom food packaging production workshop with separate zones for raw materials, printing, lamination, and bag making.
Fully Automated Production Line: 10-color high-speed gravure printing machine, dry solvent-free laminating machine, fully automatic high-speed bag making machine, intelligent slitting and inspection line; capable of handling large-scale brand full-container continuous orders.
Three-tiered full inspection system: Raw material incoming inspection → Semi-finished product composite barrier inspection → Finished product 100% appearance + heat-sealing sampling inspection, with each batch accompanied by a factory quality inspection report.

2. Printed Sample (same process as mass production, including color printing, lamination, and complete bag making): 5–7 business days;
3. Sample Delivery: Shipped via SF Express/International DHL, etc., with a small material testing sample included;
4. Customer Feedback and Modifications: Two free adjustments are allowed for printing color difference, size, and bag structure. A third minor adjustment will incur only a small consumable cost;
5. Mass production printing roller production can only begin after the sample is signed and returned for confirmation.
Q: What is the Minimum Order Quantity (MOQ) for Special Use Food Bags?
A: 1. Digital quick printing small-batch trial orders: MOQ as low as 500-1000 pieces, no need to make steel plates, suitable for new product testing;

A: Full-dimensional free customization: Size, thickness, printing patterns, spout/zipper/vent valve/window/hot stamping, etc., can all be adjusted as needed; our in-house design team provides free renderings, 3D renderings, and bag structure optimization. A one-time plate roller fee is charged only for mass production; this fee is refundable for long-term repeat customers who accumulate sufficient purchases.
Q: Packaging is easily damaged during long-distance sea freight. How does your company ensure its integrity during transport? How is damage handled?
A: Double-layer moisture-proof cushioning export cartons + waterproof stretch film significantly reduce the damage rate; if customers receive a batch of damaged goods, we will verify the quantity within 24 hours, arrange for free replacement production and reshipment, and assist with claims processing from the logistics company, so customers do not bear any losses.
