Bagasse Pulp Specifications: Bleached vs Unbleached Sugarcane Pulp

08:58

Choosing polpa di bagassa for paper or molded fiber production starts with the specifications your line can accept. Brightness affects appearance; dirt count affects visible defects; moisture, beating degree and delivery format affect receiving and processing. A product description that says only “sugarcane pulp” cannot answer those purchasing questions.

This guide compares Sheeon’s published specifications for bleached and unbleached sugarcane bagasse pulp. Use the figures to shortlist a grade, then request a current specification sheet and lot-specific test results before writing limits into a purchase order.

Bleached Bagasse Pulp Specifications

The following figures describe the published bleached grade. A published range is a starting point for an RFQ; confirm the current grade specification and the test method used for each contract-critical value.

For a buyer comparing bagasse pulp sheets, the sheet dimensions alone do not establish shipment weight or container capacity. Request the sheets per bale or pack, bale weight, wrapping details and loading plan with the quotation.

Unbleached Bagasse Pulp Specifications

Unbleached pulp is an option when a white finished surface is not required. Its suitability for a particular molded fiber or paper product still depends on trial results, the process formulation and the finished product’s performance requirements.

Parametro Published specification
Luminosità 40–43%
Contenuto di impurità, 0,3–5,0 mm² <40 mm²/500 g
Contenuto di impurità, >5,0 mm² Nessuno
Grammatura 500–530 g/m²
Peso del fardello 250 kg ADMT
Umidità 14 ± 21 TP3T
pH <8,0
Bale dimensions 700 × 800 × 600 mm
Grado di battitura 18°SR

Which Bagasse Pulp Grade Fits Your Application?

When should you consider bleached bagasse pulp?

Consider the bleached grade when the intended sheet or molded product needs a lighter appearance. Its published brightness is above 80%, and the supplied specification includes tensile, tear and burst figures. Confirm appearance, strength and processing behavior on your own equipment before approving a production order.

When should you consider unbleached bagasse pulp?

Consider the unbleached grade when the natural fiber color is acceptable and your process can work with its published 18°SR beating degree. The specification provides bale dimensions and a nominal bale weight, which are useful for planning receiving and handling. Request strength data if your end product has load-bearing or stacking requirements.

Polpa di bagassa can be evaluated as a fiber input for molded pulp packaging and paper products, including applications such as trays, protective inserts, plates or cups. These are potential downstream uses, not a claim that a given pulp grade is automatically suitable for every finished product or food-contact condition.

How to Specify Dirt Count, Brightness and Beating Degree

Dirt count: Put both particle-size bands in the RFQ. The published limits are expressed as total dirt area per 500 g for particles from 0.3 to 5.0 mm², with “none” stated for particles above 5.0 mm². Ask how samples are taken and how “none” is verified; a general promise of “low dirt” is too vague for acceptance testing.

Brightness: Set a brightness requirement only after deciding what the finished surface needs to look like. Brightness is an optical property. It does not replace tensile, tear, burst or finished-product testing.

Beating degree: The published values are 22°SR for bleached pulp and 18°SR for unbleached pulp. Ask for the measurement method and lot result, then assess whether the pulp fits your refining and forming process. A difference in °SR alone does not predict finished-product performance.

What Documents Should a Bagasse Pulp Buyer Request?

Before confirming a bulk order, request:

  • A current specification sheet identifying the exact bleached or unbleached grade.
  • A sample and its matching test report, especially for dirt count, moisture and any required strength indices.
  • Lot-specific results or agreed acceptance limits for contract-critical parameters.
  • The test method and edition used for each reported result.
  • Packing details: sheet or bale format, units per pack, dimensions, net weight and loading plan.
  • Documents supporting any food-contact or third-party testing claim relevant to the intended market and use.

If the finished product will contact food, do not treat a general “CE,” “FDA” or “SGS” statement as proof that the purchased pulp or the final molded article is compliant. EU food-contact materials fall under the framework of Regulation (EC) No 1935/2004; CE marking applies only where specific EU harmonisation rules require it. In the US, the scope of a food-contact authorization depends on the applicable authorization route and intended use. Request documents that identify the material, tested conditions and scope, then assess the finished article where required.

Bagasse Pulp Price: What to Include in an RFQ

A reliable bagasse pulp price comparison needs more than a price per kilogram. No current public price range is provided for these grades, so request a quotation against a defined purchasing specification.

Send Sheeon the following details to obtain a more useful quote:

RFQ detail What to provide
Grade Bleached or unbleached bagasse pulp
Application Paper, molded fiber packaging or another intended use
Key limits Brightness, dirt count, moisture and required strength values
Trial requirement Sample quantity and the tests you plan to run
Order volume Trial volume and expected bulk volume
Delivery Destination and requested Incoterm
Documentation Test report, packing list and any application-specific compliance documents

Request a grade-specific quote: Share your target specifications and destination with Sheeon’s sales team. Ask for the current specification sheet, sample availability, packing details and a quotation on the same weight and delivery basis you will use to compare suppliers.

FAQ

What is the difference between sugarcane pulp and bagasse pulp?

In this sourcing context, bagasse pulp refers to pulp made from sugarcane bagasse. Buyers also search for it as sugarcane pulp or sugarcane bagasse pulp. A purchase specification should identify the actual grade and measured properties rather than rely on the product name alone.

What are the main differences between bleached and unbleached bagasse pulp?

The published bleached grade has brightness above 80%, a 22°SR beating degree and a 0.3–5.0 mm² dirt-count limit below 35 mm²/500 g. The unbleached grade lists 40–43% brightness, 18°SR and a limit below 40 mm²/500 g for the same dirt band. Their published packing formats also differ.

Can bagasse pulp be used to make plates and molded packaging?

Bagasse pulp may be evaluated for molded fiber products such as plates and packaging. Whether a particular grade works depends on forming trials, the complete product formulation, required performance and any applicable food-contact requirements.

Is bleached bagasse pulp stronger than unbleached bagasse pulp?

The supplied bleached specification lists tensile, tear and burst indices, while the unbleached specification supplied here does not. The available figures therefore do not support a direct strength comparison. Request reports produced under comparable methods and conditions.

How much does bagasse pulp cost per kilogram?

There is no published price per kilogram for either grade in the supplied material. Ask for a quotation specifying grade, quantity, weight basis, packaging, destination and delivery terms so offers can be compared fairly.

Can I request a sample before a bulk order?

Sample development and technical support are described as available capabilities. Confirm sample availability, quantity, cost and the accompanying test documents directly when sending your inquiry.
