STANDARD
TESTING PROCEDURE FOR ALUMINIUM FOIL PLAIN 182MM×0.05 MM
1.0 Objective: The purpose of
this STP is to ensure the compliance of quality of 0.04MM Plain Aluminium foil.
2.0 Scope: To establish the standard testing procedure of 0.04MM Plain Aluminium
foil in Pharmaceuticals.
3.0 Procedure:
3.1 Description: Plain 0.040mm Aluminium Foil Coated
Laminated with L D P E.
3.2 Thickness: Measure the thickness of Aluminium
foil by vernier caliper at 10 points. Obtained average value should be within
limit as per specification.
3.3 Width: Measure the width of Aluminium foil by
scale. Obtained value should be within limit as per specification.
3.4 Total GSM: Take 10 x 10 cm of Aluminium
foil and, weigh it. The weight of Aluminium foil divide by length and width of
foil. The obtained value should be within limit as per specification.
3.5 Foil GSM: Take 10 x 10 cm of Aluminium
foil and separate the foil and LDPE layer, weigh the foil only. The weight
of divide foil by length and width of
foil. The obtained value should be within limit as per specification.
3.6 LDPE GSM: Take 10 x 10 cm of Aluminium
foil and separate the foil and LDPE layer, weigh the LDPE only. The weight of LDPE divide by length and width of LDPE. The
obtained value should be within limit as per specification.
3.7 Printing: Compare with the Printing as per
approved Text. Design and Colour Scheme.
Pin Hole: Check the pinholes
under adequate light with the help of magnifying glass.
