Some plastics occur in nature, like tree rubber. It’s a Matter of Chemistry. It is used predominantly as a fiber (known by the trade name “polyester”) and for bottling or packaging. This property of plasticity , often found in combination with other special properties such as low density , low electrical conductivity, transparency, and toughness, allows plastics to be made into a great variety of products. There are many reasons for this, but plastic’s lightweight and durable nature certainly assist in making it an ideal candidate for outdoor structures. They have countless uses.

Polypropylene is used for a wide number of different products. It comes from a non-renewable source (petroleum), it is contaminating and non-biodegradable (it can take more than 1000 years to decompose). We had to work with the materials that nature provided, but no more—we now design our own materials. Since all materials in contact with foods can have tiny amounts of substances transfer into the food, the FDA reviews scientific tests to determine how much is transferred and that any transfer does not pose a risk to human health.

Also known as PET, PETE or polyester, it is often used for carbonated beverages, water and … OK. A very loaded question, with a very multi-dimension answer required: * Plastics derive from pure substances, and can be precisely formed into specific shapes repetitively, with potentially variable material properties throughout the “object”.
