Overview

Multiwall kraft valve bags designed for clean, high-speed filling with strong stacking performance and print-ready surfaces.

Stable Filling

Consistent dimensions and valve construction for predictable high-speed runs.

Stacking Strength

Multi-ply builds designed to hold shape and resist handling stress.

Print-Ready

Clean surfaces to support sharp branding and traceability.

Where It Fits

Multiwall paper valve bags are a strong fit for powders and granular products that need a premium appearance and stable pallet performance.

  • Building materials (cement, mortar, additives)
  • Chemicals and minerals
  • Agriculture and feed ingredients
  • Selected food ingredients (when specification allows)

Construction Options

We tailor ply count, paper grades, and valve details to match your line and product behavior.

  • Brown kraft or white kraft outer layers
  • Barrier layers for moisture/grease (as required)
  • Optional inner liner (loose or attached) for extra protection
  • Micro-perforation or venting strategies (line-dependent)

Print & Identification

Branding and compliance often require consistent color and reliable coding.

  • High-quality print for brand visibility
  • Batch/lot coding integration (process-dependent)
  • Label and document pouch integration (optional)

FAQs

What information do you need to recommend the right build?

Target fill weight, product type/flow, packer type and spout details, dust-control requirements, storage humidity/exposure, pallet footprint, printing/coding needs, and forecast volume.

How many plies do we need?

Ply count depends on fill weight, product density, handling (drops, conveyors), stacking height/time, and puncture risk. We typically propose 2-3 build options with cost/performance tradeoffs.

Do we need micro-perforation or venting?

Venting/deaeration can improve filling stability and pallet shape for some powders, but it can reduce barrier performance. We recommend based on your product sensitivity and filling behavior.

Coating vs liner: what is the difference?

A coating is part of the paper stack; a liner is an inner layer. The best choice depends on moisture/grease exposure, cleanliness requirements, and whether venting is needed.

How do you reduce dust and leakers on high-speed lines?

Valve selection, construction geometry, and controlled venting are the main levers. We confirm your filler setup and propose a sample-and-trial path to validate performance.

What artwork files do you need for printing?

Vector artwork is preferred (AI/PDF/EPS). Share color requirements (Pantone/targets), barcode needs, and any variable-data/coding requirements so we can preflight for print consistency.
