Compare Woven and Non-Woven Polypropylene Bags
Woven and non-woven polypropylene (PPNW) bags are both made from the same material, but they differ in their manufacturing process and properties.
| Aspect | Woven Polypropylene Bags | Non-Woven Polypropylene Bags |
|---|---|---|
| Construction | Made by weaving polypropylene threads together | Created by bonding or felting polypropylene fibers without weaving |
| Strength | Strong and durable, suitable for heavier loads | Decent strength for lighter loads, less prone to fraying |
| Customizability | Can be produced in various colors, designs | Limited in design, screen printed, spot colors |
| Common Uses | Used for heavy-duty applications like grains, seeds, etc. | Popular as reusable shopping bags, promotional items, and lighter-duty uses |
Both types have their advantages and are chosen based on specific needs - woven for heavy-duty applications and non-woven for lighter uses and promotional purposes.
Why Use Polypropylene Fabric for Your Bags?

Antimicrobial
Add optional 24/7 protection against microbes, proven 99.99% effective, safe, recyclable, and compliant with BRP, FDA and EPA standards.
Easy to Clean
Polypropylene fabric is easy to clean, allowing for quick and hassle-free maintenance to keep the bags looking new.
Cost-Effective
Polypropylene is an affordable material, making bags made from it a budget-friendly option for various applications.
How We Make Our Reusable Polypropylene Bags
Polypropylene is made by taking polypropylene polymers and spinning them using heat and air into long fluffy threads, like cotton candy, then pressing the threads together between hot rollers to get a flexible but solid fabric with a weave-like texture similar to canvas.
Woven Polypropylene Manufacturing Process
The manufacturing process of woven polypropylene reusable bags involves several steps. Here's a general overview of the process:
Material Selection: Polypropylene (PP) resin is the primary raw material for woven polypropylene bags. The resin may contain additives to enhance specific properties like UV resistance or color.
Extrusion: The polypropylene resin is melted and extruded through a circular die to create flat plastic tapes. These tapes are then stretched and cooled to form a flat ribbon-like structure.
Warping: The flat tapes are wound onto spools and arranged parallel to each other. These tapes will become the warp (lengthwise) threads of the woven fabric.
Weaving: The warp tapes are interlaced with weft (crosswise) tapes using a weaving machine. The weaving process creates a woven fabric with a unique pattern and texture.
Lamination (Optional): In some cases, the woven fabric may undergo a lamination process to enhance strength, water resistance, or printability. A layer of polypropylene film may be added to one or both sides of the custom laminated bag fabric.
Printing (Optional): If desired, the woven fabric can be printed with various designs, logos, or information. This step typically occurs after lamination.
Non-woven Polypropylene Manufacturing Process
The manufacturing process for non-woven polypropylene reusable bags involves several steps. Non-woven polypropylene is a type of fabric made from thermoplastic polymer (polypropylene) fibers. Here is a general overview of the manufacturing process:
Polymer Extrusion: The process begins with the extrusion of polypropylene pellets. These pellets are melted and then extruded to form continuous filaments.
Filament Formation: The molten polypropylene is forced through spinnerets to create continuous filaments. These filaments are then cooled and solidified.
Web Formation: The filaments are laid down in a random arrangement to form a web of fibers. This web serves as the base for the non-woven fabric.
Web Bonding: The web of polypropylene fibers undergoes a bonding process to give it strength and stability. There are different methods for bonding, including heat bonding, chemical bonding, or mechanical bonding.
Calendering: The non-woven fabric may undergo calendering, a process where the material passes between heated rollers. This helps improve the fabric's smoothness and thickness uniformity.
