Decoding the “Non-Woven” Fabric
Unlike traditional woven fabrics like cotton or jute, non-woven materials are not created through the interlacing of yarns. Instead, they are formed by bonding fibers together through mechanical, thermal, or chemical processes. This creates a fabric-like material that is both strong and flexible.
The most common material used in non-woven bags is polypropylene (PP). This thermoplastic polymer is derived from petroleum and offers several advantages for bag production. It’s lightweight, durable, water-resistant, and relatively inexpensive. non woven handle bag making machine made in china
Polypropylene: The Workhorse of Non-Woven Bags
Polypropylene’s versatility makes it an ideal choice for non-woven bag manufacturing. Its inherent strength allows the bags to carry a substantial amount of weight, while its water resistance protects the contents from moisture. Additionally, polypropylene can be easily colored and printed on, allowing for customized designs and branding.
Another material sometimes used is spunbond polypropylene, which offers even greater strength and durability. This material is created by bonding continuous filaments of polypropylene together, resulting in a smoother, more uniform fabric.

Manufacturing Process of Non-Woven Bags
The creation of non-woven bags involves several steps. First, the polypropylene pellets are melted and extruded into long, thin fibers. These fibers are then laid out in a web-like structure. The next step involves bonding the fibers together. This can be achieved through various methods, such as thermal bonding (using heat and pressure), chemical bonding (using adhesives), or mechanical bonding (using needles or water jets). non woven suit cover bag made in china Finally, the bonded fabric is cut and sewn into the desired bag shape, adding handles and other features as needed.
Variations and Additives
While polypropylene is the primary material, other materials and additives can be incorporated to enhance the properties of non-woven bags. For example, calcium carbonate can be added to increase stiffness and opacity. Recycled materials are also becoming more common, contributing to the sustainability of non-woven bags. curtain bag made of recycled pp non-woven
Different Types of Non-Woven Bags
Non-woven bags come in a variety of styles and sizes, each suited for a particular purpose. Tote bags, shopping bags, promotional bags, and even garment bags can be made from non-woven fabrics. flexo printing plates 2.28mm for non-woven bag made in china The versatility of the material allows for customization in terms of size, shape, handle type, and printing options.
