Pineapple-leaf fibre

Higher plant content than most sheet alternatives, but the resin or coating layer still determines wet performance and it is the layer suppliers describe least. The leaves are an agricultural by-product, which is a genuine circularity argument — but it is a feedstock argument, not a durability argument, and the two are often conflated in sales material.

Two marks you will not find on the finished sheet, whatever a supplier implies. GOTS labels textiles containing at least 70% certified organic fibre certified to an IFOAM-family farming standard, and caps additional virgin synthetic material at 10% — a sheet that is 20–40% synthetic cannot qualify on either count, and where GOTS is mentioned in pineapple marketing it normally refers to GOTS-approved colourants, not to the material. FSC covers forest-derived material, including non-timber forest products such as cork and bamboo; pineapple is an agricultural crop, so a certificate number run against the FSC database will not return this material.
