PP Baler Twine vs Natural Fiber Twine: Which Is Better? - Grepl

Home
Blogs

Twine may look simple, but it plays an essential role across multiple industries agriculture, packaging, horticulture, recycling, warehousing, construction, and transportation. From tying hay bales to securing goods in storage, from crop bundling to construction material binding, the quality of twine directly affects safety, efficiency, and durability.

Among all options available today, the two most widely used types are PP baler twine and natural fiber twine. While PP baler twine (polypropylene twine) is valued for its high tensile strength, weather resistance, and compatibility with baling machines, natural fiber twine stands out as a biodegradable, eco friendly twine commonly used for gardening, décor, and light packaging.

This detailed comparison will help you understand which twine is better suited for agriculture, industrial packaging, construction twine applications, and everyday use.

What Is PP Baler Twine?

What Is PP Baler Twine

PP baler twine, also known as polypropylene twine, is a synthetic twine made from strong, high-quality plastic fibers. These fibers are extruded, stretched, and twisted to achieve excellent strength and consistency.

From grepl’s product range, PP baler twine is known for:

High tensile strength
Uniform thickness for smooth knotting
UV resistance for outdoor environments
Moisture & chemical resistance
Lightweight and flexible structure
Multiple denier sizes for different load capacities
Breaking strength ranging from 27.5 kgf to 660 kgf
Colors for easy identification
Compatibility with manual and automatic balers

Because of these features, PP baler twine is widely used as agricultural baler twine, hay baler twine, round baler twine, and polypropylene packaging twine across agriculture, recycling, warehousing, and industrial sectors.

What Is Natural Fiber Twine?

What Is Natural Fiber Twine

Natural fiber twine includes fibers such as jute, sisal, cotton, and hemp all of which are derived from plants. It naturally decomposes and does not leave behind harmful residues, making it a preferred choice for eco-friendly applications.

Typical qualities include:

100% biodegradable twine
Highly eco-friendly
Chemical-free
Strong natural grip
Rustic and traditional look
Ideal for gardening, décor, plant support, and light packaging

However, natural fiber twine has drawbacks: It absorbs water, weakens under sunlight, molds in humidity, and cannot handle the load capacity required for baling machines, construction, or industrial packaging.

PP Baler Twine vs Natural Fiber Twine: Key Differences

Below is a quick comparison:

Feature	PP Baler Twine	Natural Fiber Twine
Material	Polypropylene (synthetic)	Jute, sisal, hemp, cotton
Strength	Very high	Moderate
Breaking Load	27.5 – 660 kgf	Limited (often below 50–80 kgf)
Weather Resistance	Excellent	Poor to Moderate
Moisture Resistance	100% waterproof	Absorbs water
UV Resistance	High	Low
Lifespan	Long	Short
Eco-Impact	Recyclable	Biodegradable
Machine Compatibility	Excellent	Not suitable
Cost per Use	Low (long life)	High (frequent replacement)
Best Use	Heavy agriculture, construction, packaging	Gardening, décor, light bundling

Which Twine Is Stronger and More Durable?

In terms of pure strength, PP baler twine is far superior.

Examples from grepl’s specification chart:

5000 denier: 27.5 kgf (light agricultural tying)
120000 denier: 660 kgf (heavy hay baling, industrial packaging)

Natural fiber twine cannot match this level of strength.It:

Breaks under heavy load
Weakens when wet
Frays under pressure
Develops mold in humid conditions

Therefore, for baler machines, heavy crop bundling, construction material binding, industrial packaging, and transport securement, PP baler twine is the clear winner.

Which Twine Offers Better Outdoor Performance?

Outdoor use exposes twine to sunlight, moisture, chemicals, and microbial activity. In these conditions:

PP Baler Twine Advantages

UV resistant twine: Makes it long-lasting in open fields and sunlight.
Weatherproof: Performs consistently in rain, heat, and dust.
Chemical resistant: Safe around fertilizers and farm chemicals.
Stays strong even when wet: No swelling or weakening in moisture.
Does not rot or mold: Suitable for long-term outdoor storage.

Natural Fiber Twine Weaknesses

Absorbs water: Leads to swelling and faster breakage.
Develops mold/mildew: Occurs in humid climates and rainy seasons.
Weakens in sunlight: UV rays dry and crack natural fibers.
Breaks under extreme outdoor exposure: Short lifespan limits usability.

This makes polypropylene twine the superior choice for farming, recycling, transportation, landscaping, and long-term outdoor usage.

For long-term outdoor usage farming, construction, recycling, forestry, transportation polypropylene twine is unmatched

Which Twine Is More Eco-Friendly?

The eco-friendliness question is often a deciding factor:

Natural Fiber Twine Eco Champion

Fully biodegradable
Compostable
Made from plants
Chemical-free
Naturally safe for soil & water

PP Baler Twine Responsible When Recycled

Not biodegradable
But 100% recyclable
Longer lifespan reduces waste
Lower replacement reduces environmental burden

If the priority is sustainability for light applications, natural fiber twine wins.For heavy-duty use where replacements cause more waste, PP twine becomes the practical eco-efficient choice.

Conclusion:

Light-duty, sustainability-focused applications: Natural Fiber Twine
Heavy-duty use where frequent replacements cause more waste: PP Baler Twine

Which Twine Is Best for Agriculture and Baling?

PP Baler Twine for Heavy-Duty Agriculture:

PP baler twine is the industry standard for farms that rely on baling machines or handle large crop loads.

Where PP Twine Dominates:

Hay baling: handles high compression without snapping.
Silage baling: remains strong in moist, fermented environments.
Crop transport: secure bundling during movement.
Forestry applications: ideal for bundling logs and branches.
Waste handling: robust enough for recycling bundles.
Landscaping bundles: survives prolonged outdoor exposure.

Why farmers prefer it:Its UV resistance, machine compatibility, and load capacity outperform any natural fiber option.Variants such as 20000 baler twine and 40000 baler twine are often preferred for medium and heavy crop loads.

Natural Fiber Twine for Light Farming:

While it cannot support machine baling, it is very useful in garden-level agriculture.

Best Uses:

Plant tying: gentle on delicate stems.
Supporting small crops: perfect for tomatoes, chilies, beans, etc.
Eco-friendly gardening: safe for organic and home farms.

Farming conclusion:

Large farms, machines, heavy crops: PP Baler Twine
Home gardens, small crops, sustainability needs: Natural Fiber Twine

Which Twine Works Better for Construction and Industrial Packaging?

PP baler twine is designed for:

Construction binding
Heavy-duty packaging
Warehouse stock bundling
Textile industry
Transport securement
Long-term load tension

Natural fiber twine is limited to:

Craft packaging
Gift décor
Low-load retail use

Thus, for industries requiring reliability and safety, PP baler twine easily wins.

Cost Comparison: PP Twine vs Natural Fiber Twine

PP Baler Twine – Better Long-Term Value

Even if the upfront price may be slightly higher, PP baler twine offers strong economic benefits:

Long lifespan: fewer replacements
High durability: less material waste
Ideal for bulk use: reduces per-unit cost
