♥ speaks to me

Packaging material for the product act as a barrier that provide protection from external damaging effects.

For our product, Low Density Polyethylene (LDPE) plastic is use.



LDPE is translucent, flexible, good barrier to water vapour and is relatively inert. Being translucent, it is very desirable to consumers as it allows consumer to see the product through the packaging. Being a flexible packaging, we will not take up space during distribution and thus allows efficient distribution of product from producer to consumers. Being a good barrier to water vapour, it prevents moisture from entering the product and so prevents the growth of microbes which will bring harm to the consumers. Also, since the plastic is relatively inert, it is resistant to chemical and will not have any reaction with the product itself. With this, it prevents the migration of migrants from the packaging to the product that may cause potential harm to the consumers and may also have adverse effect on the flavor & acceptability of the product. It also prevents the sorption of volatiles substances from the product into the plastic which may result in a loss of aromas or flavor of the product.

However, LDPE plastic has low gas barrier which is relatively undesirable as oxygen may enter the packaging which may cause an increase in aerobic microbes.
