What is the Difference Between Spunbond and Meltblown Polypropylene?
The main difference between meltblown and spunbond polypropylene is their manufacturing process. Spunbond involves extruding continuous filaments that are laid down on a conveyor belt, while meltblown uses high-velocity air to blow molten polypropylene, creating fine fibers with a random arrangement.
But while they’re both made from polypropylene and go through different a manufacturing flow, they have significant differences in terms of material composition, properties, and applications.
Spunbond vs Meltblown Manufacturing Process
Meltblown fabric is created through a specialized and precise process known as meltblowing (no surprise there!). The procedure’s key feature lies in its ability to produce fibers with diameters in the micrometer range, resulting in a highly porous structure:
- Pellets: It begins with polypropylene resin pellets, which are melted and then extruded through small nozzles called spinnerets.
- Blown air: High-velocity hot air is blown across the extruded molten polymer, causing it to stretch and form ultrafine fibers.
- Web: These fibers are randomly collected onto a moving conveyor belt, creating a non-woven web.
In contrast, the spunbond procedure is:
- Extrusion: Initially, the process extrudes continuous filaments of polypropylene polymer from a spinneret.
- Conveyor: These filaments are then laid down on a moving conveyor belt
- Bonding: They’re then bonded together through mechanical, thermal, or chemical processes.
The combination of extrusion and bonding creates a non-woven that can withstand significant stress and wear.
Meltblown vs Spunbond: Material Composition and Structure
Meltblown and spunbond materials exhibit unique material compositions and structures, giving rise to their individual properties and functionalities.
Since both fabrics are primarily composed of polypropylene—a thermoplastic polymer widely used in the textile industry—they both have low density, chemical resistance, and thermal stability, making them well-suited for multiple applications (more on this below!)
Meltblown
For meltblowns, its ability to be melted and extruded into ultrafine fibers is central to its filtration efficiency. Meltblown fabrics may also incorporate additives or treatments to enhance specific properties, like fluid repellency or electrostatic charge for improved filtration.
The unique manufacturing process of meltblowns we discussed above results in an intricate and highly porous structure and a non-woven web with randomly oriented fibers.
This random arrangement forms a dense network with numerous small pores, allowing for efficient particle capture. As such, the high surface area of the fine fibers contributes to the fabric’s exceptional filtration performance, enabling it to trap even the tiniest particles.
Spunbond
Like meltblown, spunbonds can incorporate additives or treatments to enhance specific properties, depending on the intended application.
Spunbond fabrics’ manufacturing procedure results in a strong and uniform non-woven structure with a smooth and consistent surface, making them well-suited for printing and lamination processes.
Applications of Spunbond Nonwovens vs Meltblown
Meltblown and spunbonds find diverse applications across various industries, each capitalizing on its distinct properties.
Meltblown Fabric Applications
Meltblown fabrics are widely recognized for their exceptional filtration capabilities since their fine and porous structure enables them to efficiently capture microscopic particles, making them vital components in medical and hygiene products.
In particular, it’s extensively used in the following to provide superior airborne particle filtering, protecting healthcare workers and the public from infectious agents.:
- Surgical masks
- N95 respirators
- Other personal protective equipment (PPE)
Beyond healthcare, meltblown’s efficiency extends to air and liquid filtration systems, particularly in air purifiers, vacuum cleaner bags, and water filters, ensuring cleaner and safer environments.
Additionally, meltblowns are employed in environmental applications such as oil spill cleanup, where their absorbent properties help contain and remove hazardous substances from water bodies.
Spunbond Fabric Applications
Spunbond fabrics’ robustness and versatility make them indispensable in various industries, particularly where strength and durability are paramount.
One of the most notable applications is bulk bags, used for transporting and storing bulk materials like grains, chemicals, and construction aggregates. They particularly provide reliable containment and protection for heavy loads, ensuring safe and efficient material handling.
Spunbond is also widely used in geotextiles for soil stabilization and erosion control in civil engineering projects. Its ability to withstand environmental stressors makes it suitable for enhancing soil stability and reinforcing structures, such as roads and embankments.
Moreover, the smooth and uniform surface of spunbond fabrics makes them well-suited for printing and lamination processes, enabling eye-catching designs for promotional bags and packaging.
Cost and Availability: Spunbond Polypropylene vs Meltblown
Meltblowns typically go through a more intricate manufacturing process, which can result in a higher production cost compared to spunbond. The demand for meltblown materials, especially during times of increased need for medical and filtration applications, may also influence its pricing.
On the other hand, spunbond materials, with their simpler manufacturing process and more abundant raw materials, may be more cost-effective and readily available.
The accessibility of spunbond can positively affect lead times, allowing manufacturers to respond quickly to market demands and maintain a consistent supply chain.
It’s essential for businesses to strike a balance between cost considerations and the desired properties of the material for their specific applications.
Some industries, where filtration efficiency is paramount, may prioritize the use of meltblown despite its higher cost. In contrast, others may opt for spunbond due to its favorable balance of strength, durability, and cost-effectiveness.

Environmental Impact and the Spunbond, Meltblown Difference
Both materials are derived from polypropylene—a type of plastic that poses challenges in terms of disposable waste management and recycling.
Meltblown fabrics consist of ultrafine fibers that are difficult to recycle through traditional methods. The small size of these fibers may cause challenges during separation processes, making recycling more complex.
Consequently, appropriate disposal methods and waste management practices become vital to minimize the environmental impact of used meltblown materials.
Spunbond materials offer certain advantages in terms of potential recycling and reusability. Their continuous filaments make them relatively easier to manage at end-of-life. Depending on the specific composition and treatment of the spunbonds, recycling options may be available.
Additionally, the durability and strength of spunbond materials can lead to their reuse in certain applications, extending their lifespan and reducing waste.
Spunbond vs Meltblown: Which is Better for Storage & Transportation?
When it comes to storage and transportation, choosing the right fabric is vital to ensure the safety and integrity of goods throughout the supply chain.
Meltblown and spunbond materials offer distinct advantages, catering to specific requirements in this critical aspect of various industries.
Spunbond
Spunbonds are favored for their exceptional strength and durability, making them an ideal choice for bulk bag manufacturing and for the use of storage & transportation.

Moreover, spunbond’s smooth and uniform surface allows for easy printing and customization, enabling clear labeling and branding, essential for efficient inventory management and product identification during storage and transportation.
Meltblown
While meltblown fabrics excel in filtration applications, their unique properties can also benefit storage and transportation under specific circumstances.
In scenarios where product protection from airborne particles or environmental contaminants is crucial, incorporating meltblown layers within packaging materials can add an extra layer of security. For example, using meltblown as a filtration layer within bulk bags can safeguard sensitive products from contamination during transit and storage.
Additionally, meltblown materials have found application in specialized packaging solutions designed to protect goods from specific risks, such as oil spill cleanup materials, where the absorbent nature of meltblown helps contain and manage hazardous substances during transportation and storage.
