Kraft paper is a highly durable type of paper or paperboard produced from chemical wood pulp using the Kraft process. This chemical pulping method efficiently separates cellulose fibers from lignin, yielding a pulp with low lignin content and a high sulfur ratio. This unique composition renders Kraft paper exceptionally strong, tear-resistant, and robust, distinguishing it from other paper types. It typically sports a natural brown color, though bleached variants exist. Highly recyclable and biodegradable, Kraft paper is a sustainable material widely utilized in various packaging applications for its inherent strength and natural aesthetic, contributing to eco-friendly solutions across numerous industries.
Utilizing Kraft paper in packaging bags offers distinct benefits, blending aesthetics with functionality:
Natural & Rustic Aesthetic: Provides an appealing earthy, organic, and premium look that resonates with eco-conscious brands and consumers.
Eco-Friendly & Biodegradable Options: Many Kraft paper bags incorporate biodegradable plastics or are designed for sustainability, supporting environmentally responsible branding.
Durable & Robust: Kraft paper is inherently strong, and when combined with various laminates (e.g., foil, plastic), it offers excellent structural integrity and product protection.
Excellent Printability: The natural surface of Kraft paper provides a superb canvas for custom printing, allowing for vibrant brand logos and intricate designs that enhance storytelling.
Versatile Barrier Properties: Can be laminated with different layers to achieve specific protective features like waterproofing, smell-proofing, and extended shelf-life for diverse products.

When considering Kraft paper bags from Rundongyang, pricing is dynamic and highly dependent on customization. The cost is primarily driven by material composition (e.g., Kraft paper combined with aluminum foil, various plastics, or biodegradable layers), the specific bag size and thickness, chosen style (such as stand-up pouches, flat bags, or side-gusseted designs), added features (like resealable zippers, windows, tear notches, or childproof mechanisms), and the complexity of custom printing (including number of colors and gravure plate requirements). Larger order quantities significantly reduce the unit price, benefitting from economies of scale; Rundongyang's Minimum Order Quantity (MOQ) typically starts at 5,000 pieces.
For professional buyers, several key purchase considerations are crucial. It's essential to precisely detail all customization needs, including exact dimensions, bag style, specific multi-layer material structures (e.g., Kraft/AL/PE), and any desired functional features (such as childproof zippers or enhanced smell-proof barriers). Always ensure your order meets the specified MOQ. Carefully factor in the production lead time, which is approximately 15 days for many orders, in addition to international shipping time. Leveraging Rundongyang's 15+ years of manufacturing expertise ensures consistent high-quality, food-grade bags that are durable and reliable. Providing high-resolution artwork is paramount for achieving optimal and vibrant gravure printing results. Rundongyang offers comprehensive wholesale solutions tailored to diverse applications like coffee, snacks, tea, or artisan soaps, making them a strategic partner for businesses prioritizing quality and sustainability.
Rundongyang, with over 15 years as a professional packaging bags manufacturer, employs a sophisticated, multi-stage process to produce high-quality Kraft paper packaging bags. Our comprehensive approach ensures each bag meets precise client specifications, from initial design to final delivery, leveraging advanced technology and a flexible supply chain to create solutions that perfectly blend natural aesthetics with robust protection.
Client Consultation & Design Finalization: The process begins with in-depth client consultation to understand specific packaging needs, product requirements, and branding vision. Our design team collaborates to finalize custom artwork, bag style, size, shape, and desired features, leveraging our OEM/ODM capabilities.
Material Sourcing & Preparation: High-quality Kraft paper (available in natural brown, black, white, pink, etc.) is sourced. Concurrently, various barrier films such as aluminum foil, polyethylene (PE), BOPP, or biodegradable plastics are prepared for lamination, based on the bag's functional requirements (e.g., moisture proof, smell proof).
Pre-press & Gravure Printing Plate Making: Digital artwork is meticulously prepared for printing. High-precision gravure printing cylinders are then manufactured for each color, ensuring vibrant, precise, and full-color custom printing on the selected paper or film layers.
High-Speed Printing: The chosen Kraft paper rolls (and any base film layers) are fed into advanced multi-color gravure printing presses, where custom graphics, brand logos, and product information are accurately applied at high speeds.
Lamination: For multi-layer Kraft paper bags, the printed Kraft paper is precisely laminated with the selected barrier films (e.g., foil, plastic, biodegradable layers). This crucial step integrates protective properties, enhancing the bag's strength, sealing capabilities, and shelf-life performance.
Bag Forming & Feature Integration: The continuous laminated roll proceeds to specialized bag-forming machines. Here, the material is cut, folded, and critical features are integrated. This includes the precise application and sealing of resealable zippers or zip locks, and the punching of tear notches, matte or clear windows, and hang holes.
Heat Sealing & Bag Definition: The individual bag structures are then formed by precise heat sealing of the sides and bottom. This step creates various bag types, such as stand-up pouches, flat bags, or side-gusseted bags, ensuring strong, consistent seams.
Quality Control & Inspection: Each finished Kraft paper bag undergoes stringent quality control checks. This meticulous inspection process verifies seal integrity, zipper functionality, print accuracy, color consistency, dimensions, and overall aesthetic appeal, ensuring only flawless products proceed.
Packaging & Dispatch: Approved bags are counted, carefully packaged according to client specifications, and prepared for efficient and secure shipping to clients worldwide, maintaining our commitment to timely delivery.
