What Are Kraft Paper Bags Laminated with Woven Fabric?
Think of the familiar strength of a cement sack and the natural aesthetic of brown paper—blend them and you have Kraft Paper Bags Laminated with Woven Fabric. Often nicknamed kraft-laminated woven sacks or paper-poly hybrid bags, these packages pair an outer layer of high-tensile kraft with an inner polypropylene (PP) woven fabric. The kraft face lends print-ready, eco-friendly visuals, while the PP core supplies tear resistance and moisture armour, yielding a bag that survives rough handling yet looks at home on retail shelving.
Key Features of Kraft Paper Bags Laminated with Woven Fabric
Kraft Paper Bags Laminated with Woven Fabric bring two material worlds into one chassis:
- Moisture Shield – ≤ 4 g m⁻² day⁻¹ WVTR, far drier than plain paper sacks.
- Burst Muscle – > 1200 kPa (ASTM D3786) Mullen burst courtesy of a 75 × 75 denier PP weave.
- Print Freedom – up to six-colour flexo on the kraft outer; natural brown, bleached white, or spot-varnish options.
- Stack Discipline – hybrid wall thickness just 0.35 mm, yet stacking test passes 650 kg for 24 h (ISO 2233).

How Kraft Paper Bags Laminated with Woven Fabric Are Made
VidePak begins with virgin PP tapes drawn on Austrian Starlinger FX 6.0 lines (draw ratio 1∶6.2). Over 100 circular looms weave a 70 gsm fabric at 170 rpm. In a separate line, Scandinavian kraft rolls are corona-treated to 42 dyn before German W&H extrusion coaters hot-melt a 15 µm LDPE tie-layer between paper and fabric at 280 °C. Flexographic presses lay down up to six colours with ±0.15 mm registration. Gusset formers fold edges, and bottom-paste machines create pinch or square bottoms using water-based adhesives rated for 85 °C hot-fill. Each Kraft Paper Bag Laminated with Woven Fabric is drop-tested from 0.8 m with a 40 kg payload—bags failing the < 0.5 % leak criterion are recycled on-site into PP regrind.
Where Kraft Paper Bags Laminated with Woven Fabric Excel
Animal feed mills appreciate the moisture barrier that keeps pellets crunchy. Coffee roasters love the rustic kraft look paired with foil-like protection. Construction-chemical brands exploit the tear resistance to ship 25 kg tile adhesive without double wrapping. Across the MENA region, food-aid agencies value the bags’ ability to resist monsoon humidity while remaining fully recyclable in existing PP streams. With stacking efficiency 12 % higher than multi-wall paper, exporters squeeze extra tonnes per container, trimming freight CO₂.
