FAQ

Manufacturing Technology FAQ

What makes Chia Huang kraft paper bag manufacturing different from typical paper bag manufacturers?
Chia Huang has over 50 years of experience in kraft paper bag manufacturing, integrating material property evaluation, bag structure design, printing, lamination, bag forming and quality inspection into a seamless, single-source quality process. Our carefully selected long-fiber kraft paper delivers higher load-bearing capacity and tear resistance, which is especially critical for heavy-duty kraft paper bags.
How many layers can paper bags have? How is the layer count determined?
Heavy-duty kraft paper bag structures range from 1 to 5 layers (as required), with the actual number of layers determined by content weight, moisture protection needs and transportation method. Indoor warehouse storage generally requires fewer layers, while outdoor use, overseas export or highly hygroscopic chemical materials require more layers or lamination processing. Please describe your intended use when requesting a quote, and our sales team will recommend a suitable structure.
How many colors can be printed? Can you print brand logos?
Chia Huang offers 4-color printing to print brand logos and designs, suitable for packaging that requires brand recognition, such as feed and agricultural fertilizer. Printing is typically done before processing to protect the printed surface and ensure lasting color. Once you provide your design file, we can supply an electronic printing layout file and a similar bag style as a sample reference.
Can Chia Huang handle special specifications or non-standard bag designs?
Yes, we can evaluate it. Chia Huang's bag-making production lines have the flexibility to accommodate special specifications. Many non-standard bag styles that other manufacturers say they cannot handle, Chia Huang can first assess for feasibility. Please describe your requirements as thoroughly as possible when requesting a quote, and our sales team will let you know whether it's within our capabilities.
Can we order just lamination or slitting services without making complete bags?
Yes. Chia Huang offers raw material contract processing services, accepting customer-supplied base materials for lamination, slitting, rewinding, cutting and other processing—full bag production is not required. For details, please see the raw material contract processing service page.
