PACKAGING :
Packaging means the wrapping or bottling of products to make them safe from damages during transportation and storage. It keeps a product safe and marketable and helps in identifying, describing, and promoting the product.
“Packing is the preparation of product or commodity for proper storage and/or transportation. It may entail blocking, marking, sealing, strapping, weather proofing, wrapping, etc.”

For ease of convenience, we can classify the location factors into two: geographical factors and non-geographical factors.�

�Uniformity. Refers to the quantity between and within batches of products encompassing the impurities, excipients and ingredients. The term refers to minimizing variation between the items or doses, etc. However, variations in uniformity post storage are related to the changes in the drug/product, environment or the packing of the product. Uniformity is the foundation of batch processing and manufacturing, and packaging plays a major role.��Purity. Refers not only to the percentage of the active ingredient but also the level of impurities. Similar to how innovative analytical techniques have made the identification of impurities practical, their elimination has been aided by modern chemical techniques. Pharma packaging helps prevent the drug from exposure to impurities.��

Integrity.
11
A good packaging should have such a characteristic that it creates confidence in the minds of the buyers that the contents must be of standard quality.

In order to make your drugs affordable, cost effectiveness of packaging materials should be considered. Manufactures should endavour not to compromise the integrity of their formulation while cutting cost rather they should look for a better way to reduce cost which can by reduction of wastage of packaging material.
How easy is it for a patient to use a formulation in terms of size, weight, method of opening or reclosing if appropriate during administration of the dosage form should be considered while choosing packaging material for a dosage form.
The legibility of printing is an important factor to consider while choosing and designing a package for your formulations as it serves as a source of information and identification of a formulation as explained in the importance of giving your product a perfect finish.

STABILITY TESTING AND COMPATIBILITY TESTING

�STAGE S IN THE DEVELOPMENT OF A PACKAGE PRODUCT COMBINATION:
17
�This is the stage where a product is tested in a range of possible package, usually over a range of conditions from say 200C to 450C, together with alteration in temperature –humidity range. In addition to the storage tests indicated above the immersion of pieces of package or package components if plastic, in the product or a stimulant i.e. an extractive-type-test may also be employed. Extractive tests are usually mandatory for plastics used for injectables and ophthalmic products. Feasibility tests usually extend over a period of 1-12 months. Only after a period of normally 3-6months any decision about the package is taken.
18
Formal stability test is conducted only after a suitable package –product combination is selected. By conducting the formal stability test, the shelf life of a product can be determined. Normally three large-scale batches of product in each package is selected. For long term stability test purpose the temperature is maintained at 250C with a relative humidity of 60% and in case of accelerated stability test , the temperature is maintained at 400c with a relative humidity of 75%. The samples are kept over a period of 5 years and examinations are conducted at the intervals of 0 (optimal), 3,6,9,12,18,24,30,36,48 and 60 months. The data generated are send to the regulatory authorities as part of the marketing authorization application.
19
Qualification and quality control of packaging components: ��A packaging system found acceptable for one drug product is not automatically assumed to be appropriate for another. Each application should contain enough information to show that each proposed container closure system and its components are suitable for its intended use. The type and extent of information that should be provided in an application will depend on the dosage form and the route of administration. ��Protection:�A container intended to provide protection from light or offered as a light-resistant container must meet the requirements of the USP<661> Light Transmission test. The procedure requires the use of a spectrophotometer, with the required sensitivity and accuracy, adapted for measuring the amount of light transmitted by the plastic materials used for the container. The ability of a container closure system to protect against moisture can be ascertained by performing the USP <661> Water Vapor Permeation test°. ��
20
Compatibility:�Components compatible with a dosage form will not interact sufficiently to change the quality of the product or its components. A leachability study designed to evaluate the amount and/or nature of any chemical migrating from the plastic material to the pharmaceutical product should be implemented. �Analytical techniques such as Liquid Chromatography/ Mass Spectrometry to evaluate nonvolatile organics, Gas Chromatography/Mass Spectrometry (GC/MS) to evaluate semi volatile organics, and Inductively Coupled Plasma (ICP) spectroscopy to detect and quantitate inorganic elements should be a part of this study. ��Coupling MS to LC and GC methods provides a definitive and effective tool for identifying unknown impurities and degradation products.�Other changes such as pH shifts, precipitates, and discoloration, which may cause degradation of pharmaceutical product must be evaluated.��

STANDARD AND SPECIALTY PACKAGING SOLUTION FOR THE PHARMACEUTICAL INDUSTRY:��Traceable Solutions for Medical Packaging:�The demand for safety and integrity in the area of medical packaging has taken on new and significant implications in the past two or three years. Child safety, correct dosage, patient traceability, tampering and diversion of pharmaceuticals are always an area of concern, medical packaging. �Rondo - fluted trays�For all low fragile product needs, whether they are made from glass, metal, plastic or wood, anything that needs special packaging considerations and still should be clearly visible, with the help of rondo fluted trays. The contents can be easily removed and put back after every use. �

Coding in pharmaceutical packaging:��Coding and marketing have many functions in pharmaceutical packaging. They provide expiry dates for products, lot and date codes to aid in tracing and recalls, bar codes, sales messages and other important information .. Barcodes can be read by optical scanners called barcode readers or scanned from an image by special software. Barcodes are widely used to implement Auto ID Data Capture (AIDC) systems that improve the speed and accuracy of computer data entry.���� Symbologies:��The mapping between messages and barcodes is called a symbology. The specification of a symbology includes the encoding of the single digits/characters of the message as well as the start and stop markers into bars and space, the size of the quiet zone required to be before and after the barcode as well as the computation of a checksum ���
24
Technology of barcodes:�A linear barcode is a binary code (1s and 0s). The lines and spaces are of varying thickness and printed in different combinations. To be scanned, there must be accurate printing and adequate contrast between the bars and spaces. Scanners employ various technologies to "read" codes. The two most common forms are lasers and cameras.� �Thermal transfer and inkjet printers:�Thermal transfer and inkjet printers are more appropriate for production line bar code printing. Specifically, thermal transfer printers produce high quality, legible and clear bar codes, as well as other types of codes. Because ink is not involved, there is never any quality degradation during the process. Moreover, such printers are virtually maintenance free while they can also be connected to a software network for record keeping purposes, which helps with validation. The main drawback of this technology is that although it can be set up quickly, it lacks printing speed. �����
25
Inkjet Printers:�Inkjet printers are the fastest and least expensive units available on the market. Unfortunately, there are considerable limitations to what they can print. In addition, they require frequent maintenance and can be quite messy. Another major downfall is that the print fades after successive use. Water-based inkjet fluids tend to streak and blur, while non water, soluble inkjet fluids produce a shine that reflects to the scanner and affects how the bar code is read.��Dot -Matrix printers:�Dot -Matrix printers produce low-quality codes with low contrast, although this depends on the ribbon used.��Laser printers:�Laser printers are off-line devices requiring a separate label applicator. They are subjected to toner flaking, meaning that they are unreliable for long-term bar code printing��
