Customized Kraft Paper Solutions for Your Business

As a professional manufacturer and supplier of specialty paperboard in China, ZHONGYI specializes in a comprehensive range of industrial and packaging-grade kraft papers. Our products span various wood pulp grades, basis weights, surface finishes, and functional materials, catering to diverse applications such as food packaging, premium gift boxes, industrial protection, and carton lamination. We offer both bulk stock and custom processing, providing domestic and international buyers with eco-friendly, high-toughness, and highly adaptable paper substrates.

Wood pulp composition is the key factor determining a kraft paper's toughness, burst strength, printability, and durability. Market offerings fall into three main categories—virgin pulp, blended pulp, and recycled pulp—precisely matching the requirements of high-end, mid-range, and entry-level packaging applications.

1. Virgin Pulp Kraft Paper: Manufactured from 100% virgin softwood sulfate pulp, this paper features long, dense fibers that offer excellent tear and puncture resistance. It withstands repeated folding without cracking, dusting, or becoming brittle. The surface is uniform and clean, free from color variations or impurities, making it suitable for premium processes like high-definition gradient printing, hot stamping, and lamination. Resistant to yellowing or warping during long-term storage, it is ideal for high-end food packaging, premium shopping bags, export packaging, and heavy-duty industrial protection.

2. Blended Pulp Kraft Paper: A composite of virgin pulp and high-quality recycled pulp, offering a balance of toughness and processing stability. The surface is smooth and free of significant defects, suitable for standard four-color printing, die-cutting, and lamination. Offering superior cost-performance compared to virgin pulp, it is ideal for mass-market applications such as e-commerce carton lamination, consumer goods packaging, standard gift boxes, and warehouse interleaving paper.

3. Recycled Kraft Paper: Refined from high-quality recycled waste paper pulp, this option meets basic protective standards at the lowest procurement cost. The surface may show slight, natural speckling; it is best suited for single-color text or simple block-color printing. Common uses include industrial separation sheets, inner carton liners, disposable packaging, and warehouse pallet liners.

How to choose the right basis weight and thickness? 

Basis weight directly determines the thickness, stiffness, and load-bearing capacity of kraft paper. Categories include lightweight wrapping paper, standard-grade kraft board, and heavy-duty kraft board, catering to diverse applications such as void fill, lamination and printing, structural forming, and heavy-duty protection.

1. 60g–150g Lightweight Kraft Paper: Flexible yet strong in tensile strength, this lightweight paper adds minimal logistical load. Available in both roll and sheet formats, it is primarily used for food wrapping, floral packaging, courier interleaving, garment pattern making, and the production of small paper bags and envelopes, meeting basic needs for separation, void fill, and protective wrapping.

2. 170g–300g Standard Kraft Board: Offering a balance of hardness and stiffness, this board holds its shape well, resists creasing, and maintains structural integrity. It is the most widely circulated specification on the market. It can be laminated onto corrugated board to enhance print quality or used independently to create natural-toned boxes and standard shopping bags, making it ideal for snack and specialty food packaging, creative cultural product packaging, and eco-friendly e-commerce shipping boxes.

3. 320g–450g Heavy-Duty Kraft Board: Thick and dense, this board offers superior resistance to static pressure, compression, and puncture. It maintains a robust, rigid structure that does not easily collapse. Suitable for premium gift sets, heavy-duty product packaging, vertical display stands, and industrial liners, it is designed to withstand high-stacking warehouse conditions and long-distance heavy-load logistics.

Which visual styles suit different surface finishes?

Surface finishes determine printing precision, visual texture, and brand identity. Four mainstream styles—natural kraft, white kraft, single-side glazed, and double-side glazed—cater to a wide range of design needs, from minimalist eco-friendly styles to fresh, "affordable luxury" aesthetics and high-end, sophisticated looks.

1. Natural Kraft Paper: Retains the wood's natural yellowish-brown hue without bleaching or excessive processing. It features a natural, rustic texture and excellent ink receptivity. Emphasizing an eco-friendly, natural style, it is widely used for agricultural products, simple food packaging, natural-toned shipping cartons, and minimalist creative gift boxes.

2. White Kraft Paper: Processed using a food-grade bleaching technique, the surface is clean, bright, and white, ensuring vivid color reproduction. It is available in two varieties: virgin wood pulp and recycled pulp. Made from 100% wood pulp without fluorescent agents, this paper offers high strength and is ideal for cosmetics and affordable luxury gift boxes; the recycled version offers excellent value, making it suitable for bulk packaging with standard light-colored printing.

3. Single-sided glazed kraft paper: Features a smooth side for high-definition printing and a rough side for high friction (preventing slippage during lamination); it balances print quality with processing stability, making it a mainstream choice for laminating onto corrugated boxes and mass-producing budget-friendly paper bags.

4. Double-sided glazed kraft paper: Finely polished and smooth on both sides with no texture; supports high-precision printing on both surfaces for a refined finish; ideal for mid-to-high-end packaging such as double-sided printed shopping bags, premium gift boxes, and cultural/artistic brochures.

Introduction to Functional Kraft Papers

1. Standard plain kraft paper: Eco-friendly, recyclable, stable in performance, and readily available; suitable for dry storage and standard overland logistics, meeting the vast majority of basic consumer and industrial packaging needs.

2. PE-coated (waterproof/oil-proof) kraft paper: Features a dense PE coating that blocks water and oil; resists softening and oil seepage upon contact with liquids and is easy to wipe clean; suitable for packaging baked goods, fresh produce, and oily foods, as well as for transport during rainy seasons or storage in humid port environments.

3. Food-grade kraft paper: Odorless and free from harmful leachables; complies with food-contact safety standards; safe for direct use in bakery packaging, dry food liners, and packaging for maternal and infant products, ensuring safety and compliance in food distribution.

4. Anti-rust kraft paper: Features a slow-release anti-rust coating that blocks moisture and air to inhibit metal corrosion; specifically designed for the protective wrapping of heavy industrial products such as hardware molds and mechanical parts.

5. Anti-static kraft paper: Dissipates static electricity evenly and reduces dust attraction, preventing static damage to precision electronic components; suitable for the protective wrapping and isolation of electronic accessories and industrial control products. 

Strategic Selection and Comprehensive Advantages

Kraft paper selection follows a core logic: food-grade virgin pulp for food packaging; standard-weight machine-glazed paper for laminated printing; lightweight options for wrapping and cushioning; and heavy-duty kraft board for structural molding. Specialized materials are also available to meet specific requirements such as water resistance, rust prevention, and anti-static properties.

Complementary accessories—such as corrugated dividers, paper edge protectors, and cushioning pads—can be integrated to create a comprehensive logistics protection system, significantly enhancing stability during storage and transport.

Compared to white-lined board or specialty papers, kraft paper offers superior toughness and tear resistance, is eco-friendly and recyclable, and suits a wider range of applications—perfectly bridging the gap between minimalist premium branding and heavy-duty industrial protection.
