PTVP Inst'l 30/150 30gsm Brown refers to a specific type of paper product designed for institutional use. "PTVP" likely denotes a product series or manufacturer. The "30/150" could indicate a ream count (e.g., 30 reams per carton of 150 sheets per ream, or perhaps roll length/width in some unit if it's a roll). "30gsm" specifies the paper's basis weight as 30 grams per square meter, indicating it's a relatively lightweight paper. Finally, "Brown" refers to its natural, unbleached color, often associated with kraft paper, which is known for its strength and durability in packaging. This paper is suitable for a wide range of applications in institutional settings, such as wrapping, void fill, protective interleaving, or general-purpose packaging where a lightweight, brown, and cost-effective material is required
