  TESTING OF PACKAGING MATERIAL :

TESTING OF PACKAGING MATERIAL Presented by: Mr. Sandip S. Herma M.Pharm.(sem-1),Q.A., Roll No:33 Year:2012-13 Guided by: Ms. Heena Bagada Assistant Professor & Ms. Aashka Jani Assistant Professor DEPARTMENT OF PHARMACEUTICAL SCIENCE SAURASHTRA UNIVERSITY, RAJKOT. 1

Why is it necessary? :

Why is it necessary? By testing of packaging material, we can check that this material is of required quality or not. Different tests are carried out based on the property of the material and purpose of its use. Packaging material is not only a protecting layer but also affect the stability and quality of the product. So it is necessary to qualify the packaging material as per standard data to maintain the throughout quality of the product. 2

Different type of packaging material used for pharmaceutical products: Glass Metal Plastic Rubber 6

GLASS:

GLASS 7

GLASS:

GLASS Glass is one of the most widely used materials for parenteral products. So special care has to be taken in case of the glass. Each glass container has to be tested by following pharmacopoeial tests : Test for surface hydrolytic resistance Test for hydrolytic resistance of powdered glass Light transmission test for colored glass Test for resistance to thermal shock Test for Arsenic 8

HYDROLYTIC RESISTANCE TEST:

HYDROLYTIC RESISTANCE TEST SurfaceHRT powder glassHRT PRINCIPLE: Amount of alkali leached from the glass is determined in the test. The container is filled with the pure water and maintained at specified autoclaving condition for specified time period. The leached alkali is titrated against the acid. So at neutralization point it will give the amount of alkali leached. 9

Test for surface hydrolytic resistance:

Test for surface hydrolytic resistance Nominal capacity of container (ml) Number of containers to be used Volume of test solution to be used for titration (ml) Up to 3 20 25 5 or less 10 50 6 to 30 5 50 More than 30 3 100 Take no. of container as specified below: 10

Test for hydrolytic resistance of powder glass:

Test for hydrolytic resistance of powder glass Hammer the container & collect 100g glass ( fragments should not be greater than 25mm) Powder it to obtain 20gm fragment on retain on 250 micron sieve but pass through 425 micron sieve(as per IP) Magnet passing to purify Now perform as per previous test by adding 100ml CO2 free water And Match the result with IP specifications 13

Light transmission test for colored glass:

Light transmission test for colored glass Break glass container with carborundum or diamond wheel Select wall section Put it in specimen holder of spectrometer with care Place test specimen in the spectrometer with its cylindrical axis parallel to the slit and in such a way light beam is perpendicular to the section Measure the transmission of specimen with reference to air in spectral region of the 290-450 nm continuously or with interval of 20 nm. 14

PowerPoint Presentation:

The observed light transmission for colored glass should be not more than 10% at any wavelength in the range of 290-450 nm, irrespective of the type and capacity of container. 15

Test for resistance to thermal shock:

Test for resistance to thermal shock Particularly used for blood products or biological product Empty container in autoclave(140 o C for 30min) Place in oven(250 o C for 1 hr) Fill 70% container with 0.9% of NaCl and cool to the -20 o C for 1hr After restoring to room temperature the container must comply with test for resistance to centrifugation 16

Test for Arsenic:

Test for Arsenic Carry out the test on ampoules The inner and outer surfaces are washed five times with freshly distilled water. Prepare a test solution as described in the test for Hydrolytic resistance for an adequate number of ampoules to produce 50 ml. Pipette 10 ml of the test solution from the combined contents of all the ampoules into a flask, add 10 ml of nitricacid and evaporate to dryness on a water-bath. Dry the residue in an oven at 130° for 30 minutes. 17

PowerPoint Presentation:

Cool, add to the residue 10.0 ml of hydrazine- molybdate reagent swirl to dissolve and heat under reflux on a water-bath for 20 minutes. Cool to room temperature. Determine the absorbance of the resulting solution at the maximum at about 840 nm using 10.0 ml of hydrazine- molybdate reagent as the blank. The absorbance of the test solution does not exceed the absorbance obtained by using 0.1 ml of arsenic standard solution (10 ppm As) in place of the test solution (0.1 ppm). 18

Fill the tubes with a suitable molten eye ointment base, close the open end of each tube by a double fold and allow the filled tubes to cool overnight at a temperature of 15º to 20º. A metal bacteriological filter with 4.25 cm filter paper of suitable porosity supported on suitable perforated plate H eat it above the melting range of the base. Remove the caps and apply uniform pressure to the closed end of each tube in turn, in such a manner that the time taken to express as much of the base as possible through each nozzle is not less than 20 sec. 21

This type of tests are generally used for secondary packaging materials:

This type of tests are generally used for secondary packaging materials Like…… Paper board Wooden ply Etc…… 47 Transportation test

Transport packaging testing:

Transport packaging testing Transport packaging and their contents are influenced by the modes of transport. Depending on which transport mode that is used, packages will be exposed to different kind of stresses. The main stresses are; Mechanical Strains - The most common mechanical strains on transported goods are force stresses like, stacking pressure and shocks and energy stresses like vibration and dropping. Climatic Stresses - Climate plays a vital part for the durability and performance of the packaging during the transport. Testing Methods Packaging is tested in two ways; 1) regarding their material performance 2) how they perform during the actual transportation. 48

PowerPoint Presentation:

Drop Test, ISO 2248 - The test simulates actual shocks by dropping the package and its content freely against a rigid plane surface from a predetermined height. For example, a drop test can be conducted so that the package hits the surface diagonally against one corner, as in the picture beside. 49

PowerPoint Presentation:

The Compression and Stacking Tests, ISO 12048 and 2234 - This test is performed to assess the ability of a transport package to withstand compressive forces and to protect its contents during compression. The test may also be used as a stacking test to investigate the performance of i.e. the bottom package in a stack during storage in a warehouse. 50

PowerPoint Presentation:

The Vibration Test, ISO 2247 and 8318 - Various forms of transportation vibrations can be simulated in a laboratory through a vibration test. The test-bench can be made to swing and vibrate in almost any direction with a number of frequencies and amplitudes to emulate the transportation being used. 51

PowerPoint Presentation:

The Horizontal Impact Test, ISO 2244 - Horizontal shocks are simulated by applying a horizontal velocity to the test specimen and bringing it to halt by impact with a vertical impact surface. 52

PowerPoint Presentation:

The Water-Spray Test, ISO 2875 - The test is designed so that each area of the top surface of the package is sprayed with water maintained at a constant temperature at a specified rate for a specified period. The test package shall be filled with its intended contents and closed normally, as if ready for distribution 53

PowerPoint Presentation:

The Rolling and Toppling Test, ISO 2876 AND 8768 - In a rolling test the package is placed on a horizontal impact surface with the resting surface down. The package is tilted until the point of balance on this edge is reached. Then it is permitted to overbalance without thrust so as to impact on the surface. This procedure shall be repeated until all six sides have been impacted. 54

PowerPoint Presentation:

Bending Test-EPU: 4/86:89 - the ability of the package to withstand compression is based on the bending strength and bending stiffness of the sheet material. Therefore this is a vital test to perform in order to get the best possible packaging. 55

PowerPoint Presentation:

Moisture Absorption Test - In order to determine the plywood box’s capability to protect the goods from moisture and to establish how moisture resistant the actual box will be a moisture absorption test is performed on the different batches of plywood used. 56

Bye Bye Thought:

Bye Bye Thought To secure the quality of product from external environment , protector must be also quality bonded And the same way………… “Quality of a person is highly dependent on the quality of surrounding people.” 57
