Explore our signature packaging structures, high-performance bags, and customized corporate stationery systems engineered for premium brand alignment.
The macro-economic landscape for global packaging is undergoing a structural transition. Accelerated by plastic ban mandates, the European Union's Packaging and Packaging Waste Regulation (PPWR), and international corporate decarbonization objectives, Kraft paper packaging solutions have moved from an environmental preference to a supply-chain necessity.
Global leading bag Kraft paper factories are now utilizing advanced cellulose engineering. Through long-fiber softwoods harvested from sustainably managed boreal forests, we produce Kraft liners and extensible sack papers with high Tensile Energy Absorption (TEA). This mechanical property ensures that our paper bags withstand high drops and heavy industrial payloads (ranging from retail shopping demands to building materials and food processing logistics) without tearing, minimizing product loss across multi-modal transport networks.
As a premier supplier situated within this manufacturing matrix, Yiwu Miji Trading Co., Ltd. (MIJI) collaborates with high-tier paper milling centers in Wenzhou Longgang to balance cost-efficiency with uncompromising structural properties.
Our bag Kraft paper undergoes rigorous dynamic loading and tensile strength testing. B2B purchasers rely on these standard industrial metrics:
| Property | Virgin Kraft | Recycled Kraft |
|---|---|---|
| Grammage (GSM) | 70 - 150 GSM | 80 - 180 GSM |
| Tensile Index (MD) | 75 - 95 Nm/g | 45 - 60 Nm/g |
| Burst Index | 4.0 - 5.5 kPa·m²/g | 2.5 - 3.5 kPa·m²/g |
| Cobb Value (60s) | < 30 g/m² | < 45 g/m² |
