How should I choose paper thickness?
Start from product weight, bag size, and desired hand feel. Premium bags usually need thicker stock or board structure.
Buyer guide
Practical answers for custom paper bag sourcing.
This guide is written for brand owners, packaging distributors, purchasing teams, and designers who need to specify paper bags clearly before requesting a quote.
Cost
What affects the price of custom paper bags?
Unit price is shaped by quantity, bag size, paper thickness, printing coverage, finishing, handle selection, forming method, packing requirements, and shipping destination. A larger bag does not only use more paper; it may also change printing, forming, carton volume, and freight cost.
For overseas buyers, the most useful first inquiry includes target quantity, product use, approximate dimensions, artwork, destination country, and whether the bag must look economical, standard retail, or premium.
Printing
CMYK, spot color, foil stamping, and embossing serve different goals.
CMYK is useful for full-color artwork and image-based designs. Spot color is often better when a brand needs a controlled logo color. Foil stamping creates metallic contrast, while embossing adds tactile depth to a logo or pattern.
The best print method depends on the artwork, paper surface, quantity, and desired brand feeling. When in doubt, send the artwork first and let production review the most practical method.

Artwork
What files are needed for logo printing?
Vector artwork is preferred for logos, foil stamping, embossing, and die lines. Useful file formats include AI, PDF, EPS, or SVG when prepared correctly. If only a PNG or JPG is available, production review may be limited and redraw work may be needed.
For custom structures, a dieline or layout reference helps confirm logo placement, handle position, fold areas, and safe margins before printing.
Quick decisions
Common sourcing questions buyers should settle early.
Do I need a custom size?
Use standard sizes when the product fits well. Choose custom sizing when presentation, protection, or exact fit matters.
What is MOQ?
MOQ depends on production method, material, printing setup, and finishing. Higher quantities usually reduce setup cost per bag.
Can I print on kraft paper?
Yes, but kraft paper affects color brightness. Simple dark logos often work better than delicate light colors.
When should I use foil?
Foil is best for logos, marks, or details that need premium contrast rather than full-surface decoration.
Why does freight matter?
Paper bags are bulky. Carton volume and shipping destination can influence the total landed cost significantly.
