Structural Reinforcement and Printing Capabilities
For industrial and retail packaging, structural integrity cannot fail during transit. We utilize high-viscosity, eco-friendly hot melt adhesives at all sealing points. For loads exceeding 5kg, we automatically integrate heavy-duty cardboard inserts into the bottom gusset and the top turn-over flap (handle anchor point) to prevent tearing.
For visual branding, our factory operates advanced Heidelberg offset presses. We support CMYK and Pantone (PMS) spot color printing. To protect the ink layer and enhance moisture resistance on art paper, we apply matte or gloss lamination post-printing.

Frequently Asked Questions
Q: What is the standard color tolerance for offset printing on kraft paper?
A: Due to the natural porous texture and baseline color of unbleached kraft paper, ink absorption varies. We maintain a color tolerance of ∆E ≤ 5 for kraft materials. For exact Pantone matching, we recommend coated white art paper.
Q: Will the bottom glue hold up in extreme cold or high-humidity climates?
A: Yes. We specify our hot melt adhesive based on your destination market. For cold climates, we use low-temperature resistant adhesives tested to maintain structural integrity at -15°C. Please notify our sales engineers of your shipping destination during the quotation phase.
Q: What is your minimum order quantity (MOQ) for custom-printed paper bags?
A: For standard sizes using automated production lines, our MOQ is 10,000 units to ensure unit cost efficiency. For highly customized, manual-assembly luxury bags, the MOQ starts at 3,000 units.
Q: Can you provide pre-production physical samples before mass production?
A: Yes. Once the die-line and artwork are approved, we can produce a physical prototype within 5 to 7 days. This allows you to verify material thickness, print accuracy, and handle strength before confirming the bulk order.
