It is Often called 'bendy plywood' or 'flexiply', flexible plywood is used extensively in furniture and shopfitting, wherever curves are desirable, thus demanding a panel that is extremely flexible.
Plywood such as this is available in two main types; a plywood whose manufacturing process allows it to bend more than would be expected for a given thickness, i.e. a true flexible plywood, or a plywood that will bend because it is a high quality, very thin plywood such as thin birch.
Available in both long grain ('column wrap') and cross grain ('barrel wrap') orientation, a wide range of finished thicknesses can be created by bonding more than one sheet of bendy plywood together.
Because it does not require any special equipment or prior experience, the use of flexible plywood in any curved project helps reduces the cost in labour and material to a minimum.
