1. Kraft Paper
Kraft paper is the most popular material for custom printed paper bags, valued for its durability, eco-friendliness, and natural aesthetic. It is made from unbleached wood pulp (often pine), which retains its natural brown color and fibrous texture—though it can also be bleached to a white or off-white shade (called “white kraft”).
Key Properties
Strength: High tear and tensile strength (especially “sack kraft,” a thicker variant), making it suitable for carrying moderate weight (e.g., groceries, books).
Sustainability: 100% recyclable and biodegradable; often made from recycled or FSC-certified (Forest Stewardship Council) pulp, aligning with green branding.
Print Compatibility: Works well with most printing techniques (screen printing, digital printing, offset printing). The natural brown background creates a rustic, artisanal contrast for logos or designs—ideal for brands emphasizing “handmade” or “organic” values.
Common Applications
Grocery bags, farmers’ market bags, and takeout bags (e.g., bakeries, delis).
Artisanal product packaging (e.g., handmade soaps, craft coffee, candles).
Promotional bags for eco-focused brands or events.
2. Bleached Sulfite Paper (White Paper)
Bleached sulfite paper (often referred to simply as “white paper”) is a smooth, bright white material made by bleaching wood pulp to remove color. It is lighter than kraft paper but offers a clean, crisp surface for high-quality printing.
Key Properties
Aesthetic: Bright white background enhances color vibrancy—perfect for bold logos, detailed graphics, or brands aiming for a modern, sleek look.
Smoothness: Its fine texture ensures sharp print results (e.g., high-resolution images, gradient colors) with techniques like digital or offset printing.
Weight Variability: Available in light (200–300 gsm) to medium (300–400 gsm) weights; lighter variants are used for small bags (e.g., cosmetics, candy), while heavier variants suit slightly bulkier items.
Common Applications
Retail bags for clothing, cosmetics, or electronics (e.g., boutique apparel, beauty brands).
Gift bags for holidays, birthdays, or weddings (often paired with ribbons or handles).
Promotional bags where vivid, eye-catching prints are a priority (e.g., trade show swag bags).
3. Coated Paper (Glossy/Matt)
Coated paper is a variant of bleached sulfite or kraft paper treated with a polymer or clay coating to create a glossy, matte, or satin finish. The coating enhances print quality and adds a layer of protection against moisture or grease.
Key Properties
Print Quality: The smooth, non-porous coating prevents ink absorption, resulting in sharper text, richer colors, and a professional “premium” look.
Protection: Resistant to smudges, water, and light grease (e.g., from pastries or cosmetics), making it durable for daily use.
Finish Options:
Glossy Coated: Reflective surface that makes colors pop—ideal for brands wanting a bold, attention-grabbing design (e.g., candy, children’s products).
Matt Coated: Non-reflective, soft texture that conveys elegance or sophistication—popular for luxury brands (e.g., perfumes, high-end skincare).
Common Applications
Luxury retail bags (e.g., cosmetics, jewelry, designer accessories).
Food packaging for items with minor grease (e.g., pastries, sandwiches, chocolate).
High-end promotional bags (e.g., corporate gifts, premium event swag).
4. Recycled Paper
Recycled paper is made from post-consumer waste paper (e.g., old newspapers, cardboard, or office paper) that is processed, de-inked, and re-pulped. It is a top choice for brands prioritizing circular sustainability and reducing environmental impact.
Key Properties
Eco-Credibility: Explicitly communicates a brand’s commitment to sustainability; often labeled “100% Recycled” or “Post-Consumer Recycled (PCR)” to highlight its green credentials.
Texture & Color: Has a slightly rough, speckled texture (due to recycled fibers) and a muted color palette (off-white, light brown, or gray)—creating a “vintage” or “earth-friendly” aesthetic.
Strength: Varies by fiber quality; higher-grade recycled paper (e.g., recycled kraft) can match the strength of virgin kraft paper, while lower-grade options are better for lightweight items.
Common Applications
Eco-focused retail bags (e.g., organic food stores, sustainable fashion brands).
Promotional bags for nonprofits, environmental campaigns, or “zero-waste” businesses.
Budget-friendly bags for events (e.g., farmers’ markets, community fairs).
5. Specialty Papers (for Premium or Niche Use)
Specialty papers are designed for unique aesthetic or functional needs, often used by luxury brands or businesses wanting to stand out. They include:
a. Textured Paper
Properties: Features tactile finishes like embossing (raised patterns), linen weave, or crinkle texture. Adds a “premium touch” that customers can feel.
Applications: Luxury gift bags (e.g., jewelry, wine), high-end cosmetics packaging, or corporate gift bags.
b. Metallic Paper
Properties: Infused with metallic fibers (gold, silver, copper) or coated with a metallic layer for a shimmery effect. Printable but often used for accents (e.g., foil stamping on logos).
Applications: Holiday gift bags, wedding favor bags, or luxury retail bags (e.g., perfume, high-end chocolates).
c. Grease-Resistant Paper (Parchment-Coated)
Properties: Treated with a food-safe parchment or polyethylene (PE) coating to block grease and moisture—critical for food packaging.
Applications: Fast-food bags (e.g., fries, burgers), bakery bags (e.g., croissants, donuts), or takeout bags for oily foods.
d. Laminated Paper
Properties: Layered with a thin plastic (e.g., PE) or paper laminate for extra durability, water resistance, and tear resistance.
Applications: Heavy-duty retail bags (e.g., for shoes, electronics), outdoor event bags (resistant to rain), or reusable bags designed for long-term use.
