Engineering Overview
PAPTEX Double Layer Forming Fabric strikes the ideal balance between performance and cost-effectiveness for medium-speed paper machines. The dual-layer construction features a fine paper-side warp for excellent fiber retention and sheet smoothness, supported by a coarser wear-side for durability.
Designed for packaging, kraft, corrugated, and duplex board grades at speeds of 600–1,200 m/min, this fabric delivers consistent drainage uniformity across the full machine width. The optimized weave pattern provides 400–700 CFM air permeability with ≥60 kN/m MD tensile strength — more than sufficient for standard fourdrinier and top-former configurations.
For mills seeking to upgrade from single-layer fabrics without the investment of full SSB technology, Double Layer fabric offers a compelling step up in formation quality, fiber retention, and service life at a moderate price point.

Frequently Asked Questions
Common questions about Double Layer Forming Fabric
Double Layer fabric provides significantly better fiber retention and sheet formation than single layer, with approximately 30% longer service life. The trade-off is slightly lower drainage capacity, which is usually offset by better formation quality.
