As you know, i am preparing a student in his engineering career and he needs to practise listening materials. I use youtube but i don �t get some phrases. I �d be so grateful if could help me!! My best regards from Spain.

Dear JuanBegi,

The second speaker has a VERY strong Australian accent.  For example �process� = �prices�.

I have included all the hesitations, pauses, etc. of the speakers.

I hope that this transcript helps you.

Today there are many kinds of materials used for packaging.  However, plastic in its many different forms has become the material of choice for manufacturers.  So why is plastic such a good packaging material?

Well, plastic is such a good pla � packaging material because it�s able to be used in a thermo-pouring process.  And by that I mean that we can heat it up ---erm --- and then change its shape by blowing it into a mould, cooling it down, and then it retains that shape.  So, from a very simple sheet, we are able to form quite complex shapes.  Erm, plastic is also very strong material � so � ah� we�re able to use very little plastic to make quite a robust � er � packaging product that�s able to protect our � erm � products from manufacture to market.  Erm, it�s also a very well presented material.  Erm, obviously, you see a lot of clear plastic packaging in the, in the supermarket, so, again, we�re able to display the customers� products quite clearly within the packaging.

Plastic is lightweight. This reduces transportation and energy costs especially when compared to glass. It is a good barrier against moisture and dust.  It maintains its strength, wet or dry, and it�s easy to handle.

Plastic is a relatively inexpensive material.  So, where does it come from?  Plastic is made from by-products of the petrochemical industry.  By capturing products like methane and ethane that are burned off in the manufacturing process, we are able to make polymers. These polymers are made into different plastics, using additives, and various thicknesses of plastic film. Thin plastic films are used as cling-wraps around sandwiches or fresh bakery products like cakes. Slightly thicker and double-layer films are used for chips, snack-foods and confectionery.  The tougher plastics like TEC, are used for carbonated soft-drinks, as they provide an excellent gas and moisture barrier, that�s strong and yet light-weight.
