The Versatility of Multiwall Industrial Paper Bags

Who wouldn’t want safe, efficient, and sustainable options when it comes to bulk goods packaging? The answer is no one, which is why multiwall industrial paper bags are the trusted choice across a multitude of industries.  

What are multiwall industrial paper bags?

Made from multiple layers (or “walls”) of paper, multiwall industrial paper bags are often outfitted with integrated barrier materials, like polyethylene, foil, and biodegradable films. These bag liners ensure product protection, durability, and compliance with specific industry requirements.

Get in the Game: Markets Taking Advantage of Multiwall Paper Bags

Dozens of industries rely on multiwall paper bags, with more entering the market daily, particularly in bulk goods handling. A short list of markets already being served around the globe include:

• Agriculture: animal feed, fertilizer, pet food, and livestock feed
• Construction: cement, sand, lime, stucco, and mortar
• Food production: flour, sugar, starch, salt, and dry mixes
• Raw materials: chemicals and minerals
• Pharmaceuticals and nutraceuticals: bulk powders, medicinal ingredients
• Fuel: BBQ charcoal and wood pellets
• Specialty Applications: filter media, industrial powders, specialty clays

Multiwall Industrial Paper Bags that Meet Sustainability Goals

From animal feed to pharmaceuticals, multiwall industrial paper bags serve an extensive range of markets and align with growing sustainability goals. Paper bags  are recyclable or compostable under specific industrial settings, which helps you meet your ESG and green packaging goals.

Why Multiwall Paper Bags Make Sense

Strength, combined with the potential for customization, contributes to the appeal of multiwall paper bags as a robust packaging choice, offering:

1. Exceptional Strength and Durability: Multiwall industrial paper packaging is rated for heavy loads of 25 to 100+ pounds and is tear-resistant, ensuring your products arrive in exactly the condition they are supposed to.
2. Versatile Barrier Protection: Liners protect against moisture, grease, oxygen, and even light, ensuring added levels of security for sensitive products.
3. Cost-Effective and Space-Saving Packaging: Multiwall industrial paper bags are highly cost-effective compared to their rigid counterparts. Since they ship flat, storing them before filling is easy.  
4. Custom Printing and Branding Opportunities: Transform your packaging into a mobile billboard for your brand with custom printing options.

Paper Types, Liners, and Coatings

How do you need the multiwall paper bag to perform? The answer to this question will determine which grade and additional barrier layers, if any, you need for your cargo.

• Kraft Paper: Made from virgin wood pulp, offering excellent strength and tear resistance.
• Extensible Kraft: Engineered for its stretch and high drop resistance.
• High Porosity Paper: Allows for faster air release during filling, especially important for valve bags containing fine powders like cement.
• Recycled Paper: Made from post-consumer or post-industrial fiber, lowering environmental impact.
• Water-Soluble Paper: Dissolves completely in water; ideal for specialty applications where packaging needs to break down quickly without residue.
• Liner Materials
  • Polyethylene liners (HDPE/LDPE/LLDPE or EVA) for moisture protection.
  • Foil for oxygen and light barrier.
  • Biodegradable films for sustainable applications.

• Coatings
  • Water-resistant or grease-resistant coatings can be applied for specialty needs.

Different Styles of Multiwall Paper Bags

Your product type and filling equipment are two critical factors that dictate the right bag design for your operations. Here are some of the options available:

1. Open Mouth Sewn (Sewn Open Mouth/SOM)
   • Top filled, then sewn shut. Popular for agricultural products and animal feed.
2. Pinched Bottom Open Mouth (PBOM)
   • Pre-formed, with one end sealed and the other heat-sealed after filling.
   • Fantastic for moisture-sensitive goods.
3. Valve Bags (PVSE or PVFC)
   • Filled through a valve opening, self-seals through product pressure or by vibration/heat sealing equipment
   • Ideal for fast-filling dry powders like cement, chemicals, or food ingredients
4. Self-Opening Satchel (SOS)
   • Flat-bottom style that stands upright for retail or smaller bulk packaging
5. Pasted Open Mouth (POM)
   • Pre-formed, with one end sealed and the other heat-sealed after filling or flush cut, allowing it to be sewn closed
   • An optional tear strip is included after the heat seal to allow easy access to the product.

Multiwall Industrial Paper Bags: More Than Just Packaging

As an integral part of product protection, logistical efficiency, and branding potential, multiwall industrial paper bags are far more than just packaging. With their multiple configurations, paper grades, and secure barrier options, it’s challenging to find an industry requirement they can’t satisfy.

Do your operations require strong, sustainable, and versatile bulk packaging options? If the answer is yes, multiwall paper bags are not only the top choice on the market today, but a future-proof solution that evolves with emerging materials technology.
