kraft paper recycling
Kraft paper recycling offers an eco-friendly and cost-effective alternative to virgin pulp in modern papermaking. As environmental regulations tighten, the demand for high-strength recycled fibers is rapidly increasing across the paper industry. Among various waste paper types, recycled kraft paper stands out due to its exceptional fiber strength and versatile applications. Compared with old corrugated container recycling, old magazine, or old newspaper, kraft paper demonstrates superior physical properties and adaptability.
Anyang Machinery, with decades of experience in waste paper recycling equipment, provides a one-stop kraft paper pulping solution, specifically tailored to the unique characteristics of kraft paper. Our integrated systems help clients efficiently and automatically convert waste kraft paper into high-performance recycled pulp or industrial board materials.
About Recycled Kraft Paper
Recycled kraft paper refers to post-consumer heavy-duty paper materials, such as boxes, paper bags, and industrial linerboards, collected from packaging waste, logistics, and household use. Kraft paper is a robust, long-fiber-based material produced via the kraft (sulfate) pulping process, commonly used for corrugated boxes and heavy-duty packaging, paper shopping bags and industrial wrapping, food-grade wrapping (waxed/coated kraft paper) etc.
Typically free from heavy coatings or inks, recycled kraft paper is easy to process into pulp, making it a highly potential raw material for sustainable papermaking. Key characteristics include:
- Renewable, biodegradable, recyclable — supports circular economy.
- High tensile and tear strength — derived from virgin long fibers.
- Low coating, easy to deink — minimal chemical treatment required.
- Broad availability — steady supply from logistics, e-commerce, and industry.

High Fiber Strength for Advanced Applications
Long fibers remain structurally intact after recovery, ideal for producing kraft linerboard, reinforced corrugated medium, etc.
Low Impurity Content, Easy Processing
Minimal printing or coating means fewer contaminants, allowing smooth operation in automated pulping lines.
Cost-Effective
Kraft paper waste is abundant and stable in price; energy-efficient processing reduces overall pulp cost compared to virgin pulp or coated waste.
Simple Deinking Process
Most kraft paper uses water-based ink or no ink at all, making deinking far easier than OMG or ONP. Less chemical use and lower water consumption.
Wide Recovery Channels
Widely used in logistics, packaging, food, and e-commerce industries, kraft paper ensures steady supply for recycling.
How to Safely and Efficiently Recycle Kraft Paper
Remove contaminants like oil, grease, food residue.Detach non-paper components like staples or tape.
Flatten or shred for easier handling.
Sort by type (corrugated, mixed paper, etc.).
Deliver to local recycling centers or use designated drop-off points.
