Areas
of Work
The packaging industry can be classified according to the basic packaging material used.
FLEXIBLE
Packaging is among the most widely used, as flexible materials lend themselves to wide mutation and combination possibilities. Flexible packaging is used for a variety of products from foodstuffs to toilet preparations. It is slowly replacing many other traditional packaging materials.
RIGID PLASTIC
Packaging is mainly made from polyethylene and polyester, and is useful for household storing purposes and for products such as oil, ghee, etc.
PLASTIC
Has a wide usage in the packaging industry as it can be converted into a range of materials suitable for almost; all applications, such as strip packaging using laminates for coatings, blister packaging using foil, skin packaging using polyvinyl chlorides, shrink packaging using polyethylene and polypropylene woven sacks, and many others which are now replacing traditional packaging materials such as tin, wood, and even paper.
GLASS
Containers are used by the cosmetics, soft drinks and liquor industries. But glass is under threat and is slowly being replaced by newer, more durable materials, particularly plastic. The liquor industry is beginning to use laminated pouches.
METAL
Containers especially tin and aluminium are the traditional materials used for containers. Tin is still widely used for low quality and bulk packaging, while aluminium continues to be used for items such as packaged foodstuffs toothpastes and so on, but flexible packaging is gradually taking over this share of the market too.
PAPER BOARD AND CORRUGATED BOXES
Are amongst the oldest in the industry and are used for a variety of products particularly bulk goods. Multiwall paper sacks are among the prime packaging materials for powders and granular
products, although polyethylene and polypropylene woven sacks are now being widely used.
Although the carton industry is losing its market to plastic and flexible packaging, it is still widely used, particularly for processed foods. Duplex board, triplex board or pulp board, waxed or polycoated from inside, and multi-colored printed board, find application in products like tea, coffee and baby foods, as also liquid fruit drinks, edible oils and frozen products, dental care products, soaps and shaving creams.
WOOD AND PLYWOOD
With increasing awareness regarding the effects of deforestation the use of wood as a packaging material is decreasing. Although it is used mainly for packing bulk goods like fresh fruit, it is slowly being replaced by paperboard cartons.
TEXTILES AND ANCILLARY MATERIALS
Cotton cloth and jute have been used as packaging materials for decades, particularly for coal, bulk grains, seeds, chemicals, etc. However, they are now making way for plastic and paper packaging.
