Multiwall Kraft Paper Bags with Multi-layer Structure, Moisture Proof, and Square Bottom Design for Heavy Weight Packaging

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

Made from eco-friendly, degradable raw materials, the bags contain no fluorescent agents, heavy metals, or other harmful substances. They are odorless, safe, and widely suitable for packaging and transportation of powders, granules, chemical materials, building materials, food raw materials, and various other goods.
