Aluminium Strip Foils(Laminated)

What is ALUMINIUM STRIP FOIL: 
Alminium Strip foil is an excellent barrier to moisture, vapour and gases. It completely blocks the passage of light and entry of unwanted odours. Each Tablet is individually protected.

 Laminated foils can be offered both un-printed and printed strip foil as per customers requirements in Foil/LDPE and Foil/HSL structures.

These are special foils with general lamination of LDPE of 150 gauge or 35-37 micron on the aluminium foils. Used for aluminium table packing as strips both side with printing
