In an average supermarket, which stocks 15000 items, the typical shopper passes by some 300 items per minute. Given that 53 percent of all purchases are made of impulse, the effective package operates as a five second commercial. The package must perform many of the sales tasks: attract attention, describe the product's features, and create convenience, appearance, and prestige of better packages.

2.       Company and brand image: packages contribute to the instant recognition of the company or brand.

3.       Innovation opportunities: innovation packaging can bring large benefits to consumers and profits to the producers. Soft soap concerned the market on pumps for dispensing soap. Toothpaste pump dispenses have captured 12 % of the toothpaste market because they are more convenient and less messy.
