To print your logo on a Gift paper bag, you need to provide high-resolution vector files in formats such as Adobe Illustrator (.ai), Portable Document Format (.pdf), or Encapsulated PostScript (.eps). These vector formats allow for precise scaling and color separation, ensuring a crisp, professional print without pixelation or quality loss during production.

The manufacturing and printing process of paper bags relies on plate-making techniques that transfer ink onto paper substrates. Unlike digital screens that display pixels, physical printing presses require mathematical vector paths to define where ink is applied. When a raster image (like a .jpg or .png) is enlarged for a large retail paper bag, the pixels stretch, resulting in jagged edges and blurry logos. Vector files solve this by scaling infinitely without any loss in clarity.
During the prepress stage, our technical team verifies the artwork against international quality standards. For instance, Zhejiang Chuancheng Packaging Products Co., Ltd maintains strict quality management processes certified by ISO 9001 (Certificate BMCQ0124208S). This ensures that the vector paths align perfectly with the cutting and folding lines of the paper bags. Furthermore, our paper packaging materials carry FSC CoC (Forest Chain of Custody) Certification (SAI-COC-012922), meaning the structural integrity and surface coating of our sustainable paper sacks are fully optimized to absorb printing inks without bleeding or smudging.
In practical application, having the correct file format accelerates production. For example, during our collaboration with Matalon in Greece, where we delivered 6,235,000 pieces of gift and packaging bags, having print-ready vector files enabled seamless prepress calibration, ensuring the final logo matched the client's exact branding guidelines with zero delay.
| File Format | Suitability for Printing | Pros | Cons / Requirements |
|---|---|---|---|
| Vector (.AI, .PDF, .EPS) | Highly Recommended | Infinite scalability, sharp edges, clean color separation | Requires professional design software to edit |
| Raster (.JPG, .PNG) | Not Recommended | Easy to view on any device | Pixels blur when enlarged; cannot be used for plate-making |
| PSD (.Photoshop) | Conditional | Supports layers and high-resolution details | Must be saved at 300 DPI or higher at actual print size |
Can I use a logo image downloaded from my company website?
Web images are typically saved in low-resolution (72 DPI) PNG or JPG formats to load quickly. They do not contain the vector paths or resolution required for physical printing and will appear pixelated on a paper bag.
What is the minimum order quantity and delivery time for custom printed paper bags?
Our standard Minimum Order Quantity (MOQ) for custom Gift paper bags is 5,000 PCS, with a production delivery time of 12-15 days following design approval.
Do you offer design assistance if I only have a basic image file?
Yes, we offer both OEM & ODM services. If you only have a high-resolution raster file, our design team can inspect and assist in preparing the artwork for plate-making to ensure high-fidelity printing.
Securing the correct vector artwork files (.ai, .pdf, or .eps) along with exact Pantone color codes is the most critical step in achieving a premium branded paper bag. Following these technical specifications prevents setup delays and ensures your brand image is represented with maximum clarity and impact. Our manufacturing operations support diverse business models including Factory Direct Sales, OEM & ODM Services, and Bulk Wholesale Supply, with standard payment terms of 30% or 50% deposit and the balance before delivery.
