Understanding the Different Types of PP Woven Bags: A Complete Guide by Tan Hung JSC

Packaging plays a crucial role in protecting products, ensuring safe transportation, and enhancing brand identity. Among the many packaging solutions available, PP woven bags (polypropylene woven bags) have become one of the most reliable and sustainable options worldwide. Known for their strength, versatility, and cost-effectiveness, these bags are widely used across agriculture, construction, chemicals, food, and retail industries.

At Tan Hung JSC, a leading PP woven bag manufacturer in Vietnam, we specialize in producing high-quality woven polypropylene bags that cater to diverse industry needs. In this guide, we’ll walk you through the main types of PP woven bags, their unique features, and the industries they serve—helping you choose the most suitable option for your business.

What Are PP Woven Bags?

PP woven bags are made by weaving polypropylene (PP) tapes together, creating a strong and durable fabric. Depending on their construction, lamination, and added features, these bags can be customized for different applications. From packaging rice and sugar to transporting cement and fertilizers, woven polypropylene bags are valued for their strength, reusability, and recyclability.

I. Types of PP Woven Bags Based on Lamination

1. Unlaminated PP Woven Bags

  • Description: The most basic type, made solely from woven polypropylene fabric without any lamination.

  • Key Features:

    • Breathable, allowing air circulation.

    • Cost-effective and lightweight.

    • Easy to print with simple designs.

  • Common Applications: Packaging grains (rice, corn, wheat), sand, gravel, and other non-moisture-sensitive materials.

Unlaminated bags are ideal when breathability is more important than moisture protection.

2. Laminated PP Woven Bags

Lamination adds an extra protective layer to the woven fabric, making the bags stronger and more versatile. Two main types are:

  • PE Lamination (Polyethylene):

    • Adds a thin film layer for basic moisture and dust resistance.

    • Suitable for products that need light protection.

  • BOPP Lamination (Biaxially Oriented Polypropylene):

    • Provides excellent moisture resistance.

    • Allows vibrant, high-quality printing for branding.

    • Available in glossy or matte finishes.

    • Highly durable and tear-resistant.

  • Applications: Flour, sugar, seeds, fertilizers, chemicals, and branded consumer products.

Why Choose Laminated Bags? They combine durability with excellent printability, making them perfect for companies that want functional yet visually appealing packaging.

II. Types of PP Woven Bags Based on Construction

1. Open Mouth PP Woven Bags

  • Description: Standard woven polypropylene bags with an open top, closed after filling by sewing or sealing.

  • Key Features:

    • Simple and cost-effective.

    • Suitable for manual and semi-automatic filling.

  • Applications: Rice, animal feed, fertilizer, and construction materials.

2. Valve PP Woven Bags

  • Description: Designed for fast, automated filling with a built-in valve at the top or bottom corner.

  • Key Features:

    • Allows efficient filling on production lines.

    • Self-closing valve prevents leakage.

    • Perfect for fine powders and bulk packaging.

  • Applications: Cement, flour, dry mortar mixes, and industrial powders.

3. Gusseted PP Woven Bags

  • Description: Bags with extra side or bottom folds that expand when filled.

  • Key Features:

    • Expands into a rectangular shape.

    • Allows neat stacking and efficient space use.

  • Applications: Animal feed, pet food, seeds, and fertilizers.

4. Block Bottom or Square Bottom Bags

    • Can include four lifting loops for mechanical handling (like FIBC or bulk bags).

  • Applications: Fertilizers, construction materials, and heavy agricultural products.

III. Types of PP Woven Bags Based on Special Features

1. UV Stabilized PP Woven Bags

  • Description: Bags with UV stabilizers added during production to withstand sunlight exposure.

Choosing the Right PP Woven Bag for Your Business
