US Patent 6938396 Containers for packaging glass substrates

Containers (19) are provided for packaging flexible substrates (13) such as the glass substrates used in the manufacture of liquid crystal displays. The containers include arc-shaped grooves (25) which apply an elastic strain to the substrates. The elastic strain stiffens the substrates and thus reduces the likelihood of damage to the substrates as a result of vibration during transport or sagging when held horizontally. Through the use of such grooves, dense packaging of large, thin substrates is achieved.
