This is the highest basis weight in the Manila family: the paper to choose when 6 or 9 gsm tissue can no longer withstand handling, and the last one before the jump is no longer about weight but about fiber. Its place is the perimeter — mounting tabs, sheet edges, map or plan edges — areas that are repeatedly touched.\n\n\u003ch3\u003eWhy choose Tengujo 18 gsm?\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSufficient body for handling\u003c\/strong\u003e — at 18 gsm, the sheet has significantly more body than the 6 and 9 gsm tissues: you position the strip, adjust it, and reposition it with less tendency for it to curl on itself. It is still a tissue and must be treated as such, especially when wet, but the margin for maneuver is different.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorking translucency, not veiling\u003c\/strong\u003e — it allows the lines and texture of the support underneath to be read, but it is perceived as a layer. It does not optically disappear. This is why it is a perimeter paper and not for the center of an image: if the reinforcement should not be visible over the image, lower the basis weight — 9 gsm for local reinforcement, 6 gsm if the veiling is integral.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbaca fiber, foliar, 3–6 mm, chemical pulp\u003c\/strong\u003e — this is the fiber that defines the entire Manila family.

A paper with an alkaline reserve transfers carbonate to the assembly. This Tengujo does not: what you apply is the paper and the adhesive, nothing more. It's worth noting that the entire Tengujo range falls within this same pH range, so if your intervention criteria require the exact opposite, a different basis weight is not what you need: contact us and we can discuss it.
