Sheeon Pulp Technical Team | Technical Content Team | Published: August 28, 2026<\/p>\n

Pulpe de bagasse non blanchie<\/a><\/strong><\/span> is sugarcane fiber pulp left in its natural, minimally-processed state, with brightness typically at 40\u201343% against the 80%+ of bleached grades. For molded fiber packaging manufacturers, that lower processing level translates into a different cost profile and a narrower \u2014 but specific \u2014 set of applications where whiteness isn’t the priority.<\/p>\n

What “Unbleached” Actually Changes<\/h2>\n

Skipping the bleaching stage isn’t just a color decision. It changes beating degree, moisture handling and the packaging format the pulp ships in. Sheeon’s unbleached bagasse pulp is published at 18\u00b0SR beating degree, against 22\u00b0SR for the bleached grade \u2014 meaning less fiber refining has taken place before the pulp reaches a manufacturer’s own line. For buyers doing their own re-pulping and forming, that’s a real variable, not a footnote: less upstream refining generally means more processing work on your end, offset by a lower per-ton material cost.<\/p>\n

Note what’s absent from this list: tensile, tear and burst index figures \u2014 all published for Sheeon’s bleached grade \u2014 are not disclosed for pulpe de bagasse non blanchie<\/a><\/strong><\/span> on the reviewed pages. For molded fiber applications where wall or rim strength matters, this is a figure worth requesting directly before committing to volume, rather than assuming it matches the bleached grade’s numbers.<\/p>\n

Where Unbleached Bagasse Pulp Fits in Molded Fiber Packaging<\/h2>\n

Cushioning and protective packaging inserts. Where the packaging layer isn’t visible to the end consumer, natural brown-toned fiber performs the same structural role as bleached pulp at a lower material cost, since no whitening processing is built into the price.<\/p>\n

Trays and non-visible molded components. Industrial and shipping trays that prioritize load-bearing structure over surface appearance are a common fit \u2014 dirt count under 40 mm\u00b2\/500 g is close enough to the bleached grade’s 35 mm\u00b2\/500 g threshold that visible-surface quality differences are minor for applications where the surface isn’t the selling point.<\/p>\n

Bulk furnish blending. Manufacturers running their own bleaching or whitening step downstream sometimes source unbleached pulp specifically to control that processing stage in-house rather than paying for pre-bleached material.<\/p>\n

An Edge Case Worth Flagging: Basis Weight Isn’t Finished Product Weight<\/h2>\n

Manufacturers new to sourcing sometimes read the 500\u2013530 g\/m\u00b2 basis weight figure and assume it describes the grammage of the finished molded packaging piece. It doesn’t. That figure describes the pulp sheet as delivered in bale form \u2014 before re-pulping, forming and pressing reshape the fiber into a molded product with its own thickness and weight profile. Confusing the two can throw off cost-per-unit calculations before a production run even starts; treat the 500\u2013530 g\/m\u00b2 figure as a raw-material spec, not a finished-packaging spec.<\/p>\n
