Multiwall Paper Bags: Understanding Their Types, Structure, and Market Adaptation


Opening Dialogue: Tackling Critical Client Needs
Client: “We need packaging for livestock and poultry feed that balances cost, durability, and safety. How do your multiwall paper bags address these challenges?”
VidePak:Multiwall paper bags offer unmatched structural integrity, moisture resistance, and breathability—critical for preserving feed quality. At VidePak, we tailor solutions using 100% food-grade materials, advanced anti-microbial coatings, and customizable designs to meet diverse agricultural demands. Our 16-year expertise ensures your feed stays fresh, safe, and cost-effective.


1. Introduction to Multiwall Paper Bags: Design and Functionality

Multiwall paper bags consist of 2–6 layers of kraft paper, laminated or stitched together, providing exceptional strength and barrier properties. Widely used in agriculture, these bags protect feed ingredients like grains, additives, and premixes from environmental hazards. The global animal feed packaging market, valued at $15.2 billion in 2023, is projected to grow at 4.8% CAGR through 2030, driven by rising livestock production and stringent safety regulations.

Key Structural Features:

  • Layered Construction: Enhances tear resistance (up to 50% stronger than single-ply bags).
  • Barrier Coatings: PE or PP lamination prevents moisture ingress (humidity resistance >90%).
  • Breathable Design: Reduces condensation, critical for preventing mold in poultry feed.

2. Applications in Livestock and Poultry Feed Packaging

Multiwall bags are indispensable for safeguarding:

  • Dry Feed: Pig, chicken, and turkey feed requiring long-term storage.
  • Aquafeed: Fish and shrimp pellets prone to humidity-induced spoilage.
  • Premixes and Additives: Sensitive blends needing UV and oxygen barriers.

Case Study: A Vietnamese aquafeed producer reduced spoilage rates by 30% after switching to VidePak’s 4-ply PE-coated bags with anti-fungal treatments.


3. How to Choose the Right Multiwall Bag: A Data-Driven Guide

Selecting optimal packaging involves evaluating five factors:

3.1 Cost vs. Performance

Bag TypeCost (USD/1,000 bags)Max Load (kg)Shelf Life
2-Ply Uncoated$120256 months
3-Ply PE-Laminated$1804012 months
4-Ply PP-Laminated$2405018 months

Insight: For humid climates (e.g., Southeast Asia), 4-ply PP bags reduce long-term losses despite higher upfront costs.

3.2 Safety and Hygiene

  • Anti-Microbial Treatments: Silver-ion coatings inhibit bacterial growth (99.9% reduction in Salmonella).
  • Food-Grade Inks: Compliant with FDA 21 CFR for direct contact.

3.3 Technical Parameters

  • Thickness: 150–300 GSM (higher GSM for abrasive feeds like minerals).
  • Inner Liners: Foil or PE liners for fatty additives (e.g., fish oil premixes).
  • Size Customization: Bags sized to fit automated filling lines (e.g., 50 kg for poultry, 25 kg for aquaculture).
