Hindalco's
closure stock is rolled to very fine tolerances
to yield more closure per tonne of stock and
to allow uninterrupted operation of high-speed,
multiple-cavity presses. Its strength, high
formability, low earing and printable surfaces
make it ideal for pilfer-proof caps and vial
seals. |

with runners along the length of the sheet. They
are wrapped in HDPE with hardboard on top and bottom

length of the sheets. Silica gel packets are put
in the boxes for moisture protection.
Alternatively, they are wrapped in a poly-laminated
gunny or polythene, strapped with a hoop iron strap
and clip and placed on a wooden pallet. Edge guards
are used and the sheets are wrapped with protective
thermocol sheets.
Coil:
Coil
is placed on wooden pallets in either eye-to-sky
or eye-to-wall condition, wrapped in HDPE fabric
and hardboard, and strapped with hoop iron. Silica
gel packets are used for moisture protection.
