2ply

2ply, or two-ply, is a term used to describe a product that consists of two plies, or layers, typically two strands twisted or bonded together to form a single unit. The designation is used across several industries, most notably in textiles and sheet-based consumer products. In general, a 2-ply item is thicker and stronger than its single-ply counterpart, reflecting the added layer or strand, while often costing more and using more material.

In paper products, 2-ply refers to tissues, toilet paper, paper towels, and napkins made from two thin sheets joined together. The two plies can be bonded or perforated for easy separation during use. The two-layer structure tends to improve absorption, softness, and durability, but it also increases material usage and may affect flushability or packaging.

In yarn and textiles, 2-ply describes yarn formed by twisting two strands together. This composition can alter hand feel, warmth, strength, and drape. Two-ply yarns are common in knitting and crocheting and can be used to achieve a balance between solidity and pliability. The ply count is one factor among many, including fiber type, twist, and ply direction, that influence finished fabric characteristics.

Manufacturers label products with ply counts as a quick indicator of thickness and strength, but there is no universal standard governing ply terminology across all industries. Consumers should consider the intended use, material composition, and performance requirements when interpreting a 2-ply designation.
