Question

why do we use polythene​

Answer 1

Answer:

Protection: protects vulnerable products from damage whilst in transit and from contamination or damage by moisture, humidity, gases, microorganisms, insects and light.

Preservation: preserves products for longer, which reduces waste by giving people more time to use or consume them before it is no longer suitable to do so.

Prevents waste: products kept together and spillages avoided.

Transportation: Allows transport over great distances, so that we have access to a wide variety of non-local produce that, in turn, encourages trade. It also saves space through stacking objects which make transporting more efficient.

Displays information: important information about the product, such as nutritional content or allergy advice, is displayed on packaging.

Answer 2

Answer:

Reasons why we use plastic:

To be fit for purpose, packaging must protect and preserve. Plastic packaging performs this function particularly well and provides many other advantages for consumers, suppliers and society. Plastic is:

Safe: plastic is shatter resistant, containers do not break when they are dropped or knocked over, this makes them particularly useful for certain environments, such as the bathroom, around children, at the pool, by the beach or on the go.

Hygienic: plastic keeps products free from contamination. This is particularly useful for medical packaging as packaging can be filled and sealed hygienically without any human

intervention. (e.g. sterile syringes).

Light weight: plastic packaging is lightweight and can take up less space than alternatives, which means lighter loads for planes and trucks and lower emissions.

Secure: plastic can be sealed shut or moulded into a safety mechanism (e.g. child proof locks on medication)

Durable: because plastic packaging is so durable, plastic packaging can be very thin. This means it uses fewer resources and takes up less space for transport which means fewer trucks, trains or planes are needed to transport it.

Versatile: plastics can be transformed in many different ways. They can be blown, injected or thermomoulded. This means it can be used to package pastes and sauces. A variety of decorative effects and colours are also available.

Recyclable: plastic packaging can be recycled many times to create new products, the rates of recycling and the number of different plastics that are recycled in the UK ave been increasing.
