Woven Bag Corona Treater for High-Quality Printing and Lamination

Improving Surface Treatment for Woven PP Bags

In the woven polypropylene (PP) bag industry, achieving strong ink adhesion and high-quality lamination is essential. A Woven Bag Corona Treater is a critical solution designed to increase surface energy on woven PP fabrics, enabling superior printing, coating, and lamination performance.

Corona treatment modifies the surface structure of woven bags, making them more receptive to inks, adhesives, and coatings. This process is widely used in woven sack production, flexible packaging, and industrial bag manufacturing lines.

What Is a Woven Bag Corona Treater?

A Woven Bag Corona Treater is a surface treatment machine that applies high-voltage electrical discharge to woven PP fabric. This controlled discharge increases the dyne level of the material, allowing inks and adhesives to bond effectively.

Without proper corona treatment, woven bags may suffer from:

• Poor ink adhesion

• Ink smudging or peeling

• Weak lamination bonding

• Low print quality

Why Corona Treatment Is Essential for Woven PP Bags

Enhanced Ink Adhesion

Corona treatment ensures that printing inks adhere firmly to the woven surface, resulting in sharp, long-lasting prints.

Improved Lamination Quality

For laminated woven bags, corona treatment significantly increases bonding strength between layers.

Consistent Print Results

Stable dyne levels provide uniform printing quality across the entire woven fabric width.

Reduced Production Waste

Proper surface treatment minimizes rejected prints and material waste.
