PDF-PP CAPS.pdf Aluminium Closure Stock in mill finiah
GBS 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 earring and printable surfaces make it
ideal for pilfer-proof caps and vial seals.

Packing
Sheet: Sheets are placed in wooden boxes on wooden skids with runners along the length of the sheet. They are wrapped in HDPE with hardboard on top and bottom of the stack. Hoop iron strapping runs along the 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.
Applications :
- Pilfer-proof caps
- Vial seals
- Cream containers and caps
AS Per detail application, we also use AA1060/3105/3104,H14,H16,H18 for pp caps production
