High Tensile Strength Multiwall Kraft Paper Bags with Moisture Proof PE Coating

Multi-layer kraft paper bags are manufactured using 100% pure wood pulp high-strength kraft paper through advanced multi-layer composite pressing technology. These bags feature a stiff, tear-resistant body with exceptional load-bearing capacity. An optional PE moisture-proof coating provides superior dustproof, moisture-proof, and anti-tear performance.

Crafted from eco-friendly, biodegradable raw materials, these bags contain no fluorescent agents, heavy metals, or other harmful substances. They are odorless, safe, and suitable for packaging and transporting powders, granules, chemical materials, building materials, food raw materials, and various other goods.

• Multi-layer Structure & High Tear Resistance
  Constructed with 2 to 4 layers of kraft paper bonded by high-temperature pressing. Features strong vertical and horizontal tensile strength with excellent tear and impact resistance. Prevents breakage, bottom bursting, and material leakage during filling, handling, and stacking. Ideal for packing goods weighing 20-50kg.
• Moisture & Dust Proof with Excellent Sealing
  Custom inner PE coating effectively blocks moisture and dust, preventing material caking and deterioration. Outer kraft paper is wear-resistant to avoid package damage and material contamination during transit.
• Firm Shape & Stable Stacking
  Square bottom three-dimensional forming design ensures bags stand upright neatly without collapsing in storage, optimizing warehouse space. Maintains stable shape during loading and unloading, compatible with both automatic filling machines and manual handling.
• Eco-friendly, Non-toxic & Standard Compliant
  Made of food-grade biodegradable kraft paper with zero plastic pollution, complying with waste classification and environmental regulations. Free of fluorescent agents and heavy metals, safe for direct contact with food-grade raw materials.
• Exquisite Printing for Brand Promotion
  Supports 1-4 color flexographic and offset printing. Custom logos, product names, specifications, warning marks, and QR codes available. Clear, fade-resistant printing enhances product grade and enables brand promotion and product traceability.
• Cost-effective & Widely Applicable
  Lightweight yet high strength, more eco-friendly and elegant than traditional woven bags. Reusable with reasonable cost. Suitable for domestic and overseas sales, with stable bulk supply availability.
