Industrial Kraft Paper Bags FAQ | Products, Technology, Contract Manufacturing & Orders

Chia Huang's products fall into four main categories: heavy-duty industrial paper bags (cement bags, chemical bags, feed bags, powder bags, building material bags, sugar bags), composite bag materials (PE/PP woven bags, 3-in-1 kraft paper), paper materials and raw materials (recycled kraft paper, virgin wood pulp kraft paper, etc.), and upcycled creative products. See Products for details.

25kg paper bags are the most common specification for heavy-duty packaging such as cement and fertilizer, and Chia Huang has extensive production experience with them. For other sizes or load-bearing specs, custom evaluation is available—just let us know the content weight and filling method when requesting a quote.

Heavy-duty kraft paper bags are structured with 1 to 5 layers depending on requirements. The actual number of layers depends on content weight, moisture protection needs and transport method. Indoor storage typically needs fewer layers, while outdoor use, overseas export, or highly hygroscopic materials require more layers or added laminating.

Chia Huang offers 4-color printing for logos and designs, ideal for packaging that needs brand recognition, such as feed and agricultural fertilizer bags. Printing is usually done before processing to protect the printed surface and keep colors vibrant.

Chia Huang offers toll processing—you supply the base material (such as kraft paper rolls or woven fabric rolls), and Chia Huang performs laminating, slitting, rewinding or cutting before returning it to you. You don't need to rebuild your entire supply chain; simply outsource the missing process. See Raw Material OEM Services for details.

Chia Huang's laminating process uses PE and PP film materials, and can process base materials such as kraft paper, PE/PP woven fabric, and PE/PP non-woven fabric. For aluminum foil and BOPP film, please contact us for evaluation. See Laminating for details.
