                    Notes          10.2.1 Kinds of Packaging

                                   Depending on the use of packaging materials, the packaging for export products can be classified
                                   into the following categories:

                                   Plastic Packaging

                                   The various kinds of plastic materials are used for packaging of the export products. The most
                                   common plastic materials used for packaging are polyethylene (PE) and polypropylene (PP).
                                   Polyethylene  film  has  two  main  varieties  of  consumer  packaging  namely,  low  density
                                   polyethylene (PE-LD) film and high-density polyethylene (PE-HD).
                                   PE-LD film is used for making plastic bags, shrink wrapping and stretch wrapping. This film is
                                   very useful to provide protection against moisture and dirt. It does not however, provide any
                                   mechanical protection. The exporters can use the plastic bags made of PE-LD films for wrapping
                                   articles to package products like T-shirts, table cloths, napkins, leather hand bags etc. These products
                                   are placed inside the plastic bags, which are transparent and are suited for retail display.
                                   In shrink-wrapping, a specially treated film is loosely wrapped around the product(s) and then
                                   shrunk with heat to form a tight package. This kind of wrapping is suitable for solid products
                                   like sets of drinking glasses, a group of egg-cups, sets of table mates and so on.
                                   In stretch wrapping, a thin film is tightly wound around the product, often in several layers.
                                   When  the wrap is completed, the stretched film tries to return to its original size,  thereby
                                   holding the product or group of products tightly in place.
                                   PE-HD is also used for making plastic bags because it provides better resistance against moisture
                                   and fats than PE-LD. PE-HD is more expensive than the PE-LD. Both the forms of plastic films are
                                   environment friendly as they are easy to recycle.
                                   The PP films are stronger than the PE films. It is better to use bags made of PP films for packaging
                                   textiles and garments as these can be printed or can be used in plain form as well. PP films are
                                   better than PE films in terms of providing better moisture protection but these films are more
                                   expensive. Another alternative to PP films is polyvinyl chloride (PVC) material.

                                       !
                                     Caution But from environmental point of view, PVE materials should not be used, as these
                                     are not recyclable.

                                   Plastic boxes can be used especially as retail packages for jewellery and other small, precious
                                   products. They are also well-suited to add appeal to products such as embroidered handkerchiefs
                                   or tablecloths, souvenir dolls, etc. They come in square, oval or round shapes; printed or plain.
                                   Paper Based Packaging


                                   Paper based materials are used as wrapping, as paperboard cartons or corrugated fibreboard
                                   boxes. The various types of paper can be coated with plastics, waxed or treated with anti corrosion
                                   agents. Paper is either  produced from  virgin wood  fibres or recycled fibres.  The former  is
                                   stronger than the latter.
                                   Paper wrappings provide protection  against dust and light, but do not provide mechanical
                                   protection.
                                   Paper absorbs moisture when the surrounding air is more humid than the paper, and it gives up,
                                   moisture when the surroundings are drier. Thus, paper wrappings can be used to some extent as
