Technisches Team von Sheeon Pulp | Technisches Team des Unternehmens | Veröffentlicht: September 2026

Straw pulp is a type of non-wood pulp produced from agricultural residues such as wheat straw instead of traditional wood fiber. Among different agricultural fiber materials, wheat straw pulp has become an important alternative raw material for paper production, packaging, and sustainable fiber applications.

Commercial wheat straw pulp is mainly supplied in different grades, especially TCF bleached wheat straw pulp and unbleached wheat straw pulp. These grades vary in brightness, opacity, cleanliness, strength properties, and application suitability.

For paper mills, packaging manufacturers, importers, and industrial raw material buyers, choosing the right wheat straw pulp supplier requires understanding not only the grade name but also the actual technical specifications, including fiber characteristics, moisture, dirt count, brightness, and quality consistency.

Sheeon Pulp supplies wheat straw pulp solutions for global B2B customers seeking sustainable alternatives to conventional wood-based fiber. As a China-based non-wood pulp supplier, Sheeon focuses on agricultural waste valorization, stable bulk supply, customized specifications, and international export support.

The specifications below reflect the published product data available at the time of writing. Buyers should always request a current certificate of analysis (COA) and product-specific documentation before confirming bulk orders.

What “TCF” Means for Wheat Straw Pulp

TCF stands for Totally Chlorine Free, referring to a bleaching process that avoids chlorine-based bleaching chemicals completely.

In the wheat straw pulping process, bleaching is an important stage that determines the final appearance, brightness, and suitability of pulp for different paper applications.

TCF bleaching is often considered by buyers looking for environmentally focused sustainable pulp solutions because the process does not use elemental chlorine or chlorine-containing bleaching chemicals.

However, TCF describes a bleaching method, not an automatic certification.

A pulp produced through a TCF process does not automatically mean it has:

• FSC certification
• Organic certification
• Food-contact approval
• Specific environmental certification
• Any other third-party compliance document

These certifications and approvals require separate evaluation and documentation.

For example, a buyer producing food packaging, disposable paper products, or environmentally friendly packaging materials should verify whether the specific wheat straw pulp grade meets the regulations required for their target market.

At Sheeon Pulp, we recommend that buyers evaluate:

• Bleaching process
• Fiber source
• Product specification
• Intended application
• Required certifications
• Destination market regulations

rather than relying only on a product name.

Why Wheat Straw Pulp Gets Used in Packaging and Paper Production

The demand for Weizenstrohpülpe has increased as paper manufacturers search for alternatives to traditional wood pulp.

Wheat straw is an agricultural residue generated after grain harvesting. Instead of being treated only as agricultural waste, it can be processed into valuable fiber for paper making, packaging, and other industrial applications.

Compared with conventional wood pulp, wheat straw pulp offers several potential advantages:

• Uses agricultural byproducts as raw materials
• Supports non-wood fiber development
• Provides an alternative fiber source for paper production
• Helps diversify pulp supply chains
• Supports sustainable packaging development

However, wheat straw pulp is not designed to replace every type of wood pulp application.

The best application depends on the required balance between:

Requirement	Important Consideration
Helligkeit	Important for white printing paper
Strength	Important for packaging performance
Deckkraft	Important for visual quality
Cost efficiency	Important for large-volume production
Fiber characteristics	Important for machine performance
Sustainability goals	Important for eco-friendly product positioning

In many packaging applications, unbleached wheat straw pulp can provide a practical balance between cost and performance.

For applications requiring higher brightness, cleaner appearance, and better visual quality, TCF bleached wheat straw pulp may be more suitable.

Zu den üblichen Anwendungen gehören:

• Verpackungspapier
• Food packaging materials
• Paperboard
• Corrugated medium
• Tissue-related applications
• Sustainable paper products
• Agricultural fiber-based packaging

For paper mills comparing wheat straw pulp price, the lowest purchase cost is not always the most important factor.

The real purchasing value depends on:

• Pulp consistency
• Production stability
• Required specifications
• Transportation cost
• Processing compatibility
• Final product performance

TCF Bleached vs. Unbleached Wheat Straw Pulp: Specification Comparison

Different customers require different grades of wheat straw pulp.

A packaging producer may prioritize strength and cost efficiency, while a printing paper manufacturer may focus more on brightness, cleanliness, and appearance.

The following comparison shows the key differences between Sheeon’s TCF bleached and unbleached wheat straw pulp grades.

Parameter	TCF Bleached Wheat Straw Pulp	Unbleached Wheat Straw Pulp
Helligkeit	≥75%	35–40%
Deckkraft	≥90%	≥85%
Fiber length	0.8–1.2 mm	0.8–1.2 mm
Zugfestigkeitsindex	≥45 N·m/g	≥40 N·m/g
Tränenindex	≥4.5	Not published
Burst-Index	≥3,5	Not published
Viskosität	≥300	Not published
Luftfeuchtigkeit	≤20%	14 ± 21 TP3T
pH-Wert	6,5–8,0	≤8.0
Dirt count	≤30 mm²/500 g	≤50 mm²/500 g

The fiber length is identical between the two grades because the underlying agricultural raw material is the same.

The main differences come from later processing stages, especially washing, screening, and bleaching.

For example:

• Gebleichter Weizenstrohzellstoff provides higher brightness and tighter cleanliness control.
• Ungebleichter Weizenstrohbrei provides a more natural appearance and can be suitable for cost-sensitive applications.

For buyers comparing wheat straw pulp manufacturers, technical consistency is usually more important than simply selecting a grade with the highest brightness.

A reliable supplier should provide:

• Technical data sheet
• Certificate of analysis
• Moisture information
• Brightness data
• Packaging information
• Production batch details

Understanding Wheat Straw Pulp Quality Factors

When purchasing straw pulp, buyers should evaluate several technical factors instead of focusing on one specification.

Helligkeit

Brightness describes the optical appearance of pulp.

A higher brightness value is generally preferred for:

• Druckpapier
• Schreibpapier
• White packaging
• Premium paper products

Unbleached grades usually maintain a natural brownish color because they retain more original fiber coloration.

Deckkraft

Opacity determines how effectively paper blocks light passing through the sheet.

Higher opacity helps reduce:

• Show-through
• Visual interference
• Reduced readability

For applications involving printed surfaces, opacity can significantly affect the final paper quality.

Fiber Strength

Although wheat straw fibers are generally shorter than many wood fibers, proper pulping and refining can produce useful strength characteristics.

Strength performance depends on:

• Cooking conditions
• Fiber separation
• Refining degree
• Paper formulation
• End application
• Cleanliness

Dirt count is particularly important for visually sensitive products.

Lower dirt count is usually preferred for:

• Druckpapier
• Tissue products
• Premium packaging

For industrial packaging where appearance is less critical, a slightly wider tolerance may be acceptable.

Moisture Control

Moisture affects:

Storage stability

• Shipping weight
• Repulping performance
• Warehouse conditions

International buyers should always confirm moisture requirements before shipment.

A Common Misconception: Company Certifications Don’t Automatically Apply to a Specific Grade

A common mistake in industrial purchasing is assuming that company-level certifications automatically apply to every product grade.

They do not.

A supplier may have company certifications, management system certifications, or factory compliance documents, but each individual pulp product may require separate documentation depending on the buyer’s application.

For example, a customer purchasing Weizenstrohpülpe for food packaging may require specific food-contact documentation.

A customer producing sustainable paper products may focus more on:

• Fiber traceability
• Environmental documentation
• Chemical information
• Supply chain transparency

A customer purchasing pulp for industrial packaging may focus more on:

• Strength
• Price
• Availability
• Production stability

Therefore, buyers should always request product-specific documentation.

This is especially important for international B2B purchasing because regulatory requirements vary between markets.

Sheeon Pulp recommends that buyers confirm:

• Product specification
• Applicable certificates
• Testing reports
• Compliance documents
• Intended use

before placing large-volume orders.

Choosing Between TCF Bleached and Unbleached Wheat Straw Pulp for Different Applications

Selecting the correct wheat straw pulp grade depends mainly on the final product requirements.

A packaging manufacturer, paper mill, tissue producer, or sustainable material brand may have completely different priorities. Some customers need higher brightness and cleaner appearance, while others focus on cost efficiency, strength, and stable bulk supply.

Before purchasing wheat straw pulp, buyers should first define:

• Final paper or packaging application
• Required brightness
• Strength requirements
• Printing requirements
• Food-contact requirements (if applicable)
• Target market regulations
• Monthly consumption volume
• Required certification documents

The same straw pulp grade cannot always meet every application.

1. Check Your Target Brightness First

Brightness is one of the first factors that separates TCF bleached wheat straw pulp from unbleached grades.

If the finished product requires a white appearance, printing quality, or premium visual performance, the higher brightness of bleached pulp provides a stronger starting point.

Typical applications that may prefer bleached grades include:

• White printing paper
• Schreibpapier
• Premium packaging paper
• Tissue-related products
• High-visibility sustainable paper products

Ungebleichter Weizenstrohbrei, with its natural color, is often more suitable for:

• Kraft-style packaging
• Corrugated applications
• Natural paper products
• Industrial paper grades

The right choice depends on whether appearance or cost efficiency is the higher priority.

2. Compare Dirt Count Requirements

Dirt count measures visible particles or impurities remaining in pulp.

For visually sensitive applications, cleanliness becomes especially important.

For example:

Application	Typical Priority
Druckpapier	Very high cleanliness
Seidenpapier	High cleanliness
Premium packaging	Medium to high cleanliness
Industrial packaging	Moderate cleanliness

The difference between:

• TCF Bleached Wheat Straw Pulp: ≤30 mm²/500 g
• Unbleached Wheat Straw Pulp: ≤50 mm²/500 g

shows that different grades are designed for different expectations.

A buyer searching for wheat straw paper manufacturers should therefore ask not only about sustainability but also about actual quality-control data.

3. Match Moisture Specification With Storage Conditions

Moisture is often overlooked during pulp purchasing.

However, for international buyers importing bulk wheat straw pulp, moisture affects:

• Shipping weight
• Storage conditions
• Warehouse management
• Repulping efficiency
• Long-distance transportation stability

Before confirming an order, buyers should understand:

• Moisture tolerance
• Packing method
• Bale protection
• Container loading conditions
• Expected storage period

A supplier experienced in global export should be able to provide clear packing and transportation recommendations.

4. Request Complete Technical Data Before Bulk Purchasing

Some buyers compare suppliers only by:

• Wheat straw pulp price
• Ton price
• Shipping cost

However, the lowest quotation does not always represent the lowest total production cost.

A complete comparison should include:

 

Technical Factor	Why It Matters
Helligkeit	Determines visual quality
Deckkraft	Influences printing appearance
Faserfestigkeit	Affects paper performance
Luftfeuchtigkeit	Impacts storage and shipping
Dirt count	Controls appearance
Consistency	Reduces production variation
Verpackung	Protects material during transport

For industrial buyers, stable quality is usually more valuable than a small difference in initial purchase price.

5. Request Product-Specific Documentation

For international procurement, buyers should request:

• Certificate of Analysis (COA)
• Technical Data Sheet (TDS)
• Product specification
• Packing details
• Production information
• Applicable compliance documents

This is especially important for customers purchasing:

• Food packaging materials
• Sustainable paper products
• Export-oriented paper grades
• Large-volume pulp supply

A professional wheat straw pulp supplier should support technical communication before and after ordering.

Trade-Offs to Weigh

Both TCF bleached and unbleached wheat straw pulp have advantages depending on the target application.

The better choice is not always the brightest pulp or the cheapest pulp.

It is the grade that best matches the final production requirement.

TCF Bleached Wheat Straw Pulp Advantages

The main advantage of TCF bleached wheat straw pulp is improved appearance and cleaner visual performance.

Key benefits include:

Higher Brightness

With brightness ≥75%, bleached wheat straw pulp is more suitable for products requiring a lighter appearance.
