Bleached bagasse pulp is sugarcane-fiber pulp processed to remove color and lignin residue, typically reaching brightness above 80%. It’s used in molded fiber tableware, food packaging board and printing-grade paper where a white base sheet and food-contact suitability both matter.<\/p>\n

What the Brightness Number Actually Tells You<\/h2>\n

Most marketplace listings for bleached bagasse pulp stop at brightness and gram weight. That’s enough to compare price tags, but not enough to know whether a pulp lot will run cleanly through a molding line or hold up under wet-strength testing. Brightness measures whiteness, not fiber strength \u2014 a batch can hit 80%+ brightness and still underperform on tear resistance if the bleaching process degraded fiber length.<\/p>\n

For Sheeon’s bleached bagasse pulp,<\/a> <\/strong><\/span>the published brightness threshold is >80%, alongside separate \u2014 and independently important \u2014 figures for dirt count, tensile index, tear index and burst index. Treating any single number as a stand-in for overall quality is the first mistake buyers make when comparing suppliers off a summary spec.<\/p>\n

Compared with the typical marketplace product page \u2014 which usually lists gram weight, MOQ and a price band and stops there \u2014 this covers the four values that actually predict runability: dirt count, tensile index, tear index and burst index.<\/p>\n

Bleached vs. Unbleached: What Changes at the Fiber Level<\/h2>\n

Buyers sourcing for the first time sometimes assume “bleached” and “unbleached” are just a color choice. The spec sheet says otherwise.<\/p>\n\n\n\n\n\n\n\n\n

The lower beating degree on the unbleached grade means less fiber refining before use, which typically suits lower-cost molded packaging where surface whiteness isn’t a requirement. Bleached stock’s higher beating degree reflects the additional processing needed to reach printing- and food-packaging-grade brightness.<\/p>\n
