Kraft paper bags offer a distinctive combination of natural aesthetics, sustainability credentials, and functional performance that no synthetic flexible packaging can fully replicate. For brands prioritizing environmental responsibility and a premium artisanal appearance, kraft paper packaging delivers on both fronts.

What Is Kraft Paper?

Kraft paper is produced using the kraft process, a wood pulping method that uses sodium hydroxide and sodium sulfide to break down wood fibers while maintaining exceptional strength. The resulting paper is notably strong, tear-resistant, and has the characteristic natural brown color that makes kraft packaging instantly recognizable.

Kraft paper can be bleached to white for a brighter appearance or left natural for the earthy, rustic look that appeals to premium and artisanal brands.

Applications for Kraft Paper Bags

Food Products

• Bakery items — Paper bags for bread, pastries, and baked goods (natural brown matches artisanal positioning)
• Confectionery — Candy boxes, chocolate boxes, and treat bags
• Coffee — Kraft outer bags for coffee bean packaging (with inner barrier liner)
• Produce — Paper bags for nuts, dried fruits, and bulk grains

Non-Food

• Pet treats — Natural kraft appearance aligns with pet health and natural product positioning
• Gift and craft packaging — Versatile surface accepts printing, stamps, and hand-written labels
• Industrial applications — Heavy-duty kraft bags for powders and granules

Kraft Paper Bag Types

Flat Paper Bags

Simple flat bags with heat-sealed or folded closures. Used for lightweight products (pastries, small confectionery items) where shelf presentation is secondary to convenience.

Gusseted Paper Bags

Bags with expandable side gussets that allow them to stand upright when filled. Used for larger quantities of nuts, grains, pet treats, and similar products.

Kraft Stand-Up Pouches

Kraft-coated or kraft-laminated pouches that combine paper aesthetics with flexible packaging functionality. The inner barrier layer provides moisture and oxygen protection that kraft paper alone cannot.

Custom Printing on Kraft Paper

Kraft paper accepts both flexographic and offset printing methods:

Flexographic Printing

Cost-effective for medium runs (5,000-50,000 units). Flexo printing on kraft produces slightly muted colors compared to gravure but at significantly lower cost. Best for bold, high-contrast designs with limited color counts.

Offset Lithography

Premium print quality with excellent color reproduction. Used for premium kraft packaging where photographic imagery and fine details are required. Higher tooling cost but superior print quality.

Sustainability of Kraft Paper Packaging

Kraft paper is one of the most recyclable and compostable packaging materials available:

• FSC-certified kraft paper — Ensures wood pulp comes from responsibly managed forests
• Recyclable — Paper bags are accepted in standard paper recycling streams
• Home compostable — Uncoated kraft paper is fully compostable; kraft with barrier coatings requires evaluation
• Lower carbon footprint — Paper production generates less carbon than equivalent plastic production

Frequently Asked Questions

Can kraft paper bags provide adequate barrier for food products?

Plain kraft paper alone has poor moisture and oxygen barrier. For food products, GGPbag typically recommends kraft laminated with a thin PE or PLA barrier layer inside. This gives you the natural kraft appearance while providing the barrier protection your product needs. The inner liner can be specified to match your compostability requirements.

What is the minimum order quantity for custom printed kraft bags?

For custom flexo-printed kraft bags, MOQs typically start at 10,000 units. For offset-printed premium kraft packaging, minimums are typically 5,000 units. GGPbag also offers digital printing on kraft for smaller runs starting at 500 units.

Can I get kraft bags with window cutouts?

Yes. Die-cut windows with PET or compostable PLA window films are available for kraft bags. Windows allow consumers to see the product inside while maintaining the paper bag’s sustainability positioning and some barrier properties.
