    The only one I know is Pet, we put it in our coffee years ago. Now I drink it black. Google is a wonderful thing.

    PP5 participates in the regulation of glucocorticoid receptor nucleocytoplasmic shuttling, and that the GR-induced transcriptional activity observed when the expression of PP5 is suppressed by treatment with ISIS 15534 results from the nuclear accumulation of GR in a form that is capable of binding DNA yet still requires agonist to elicit maximal transcriptional activation.

    PET stands for polyethylene terephthalate, a plastic resin and a form of polyester. Polyethylene terephthalate is a polymer that is formed by combining two monomers called modified ethylene glycol and purified terephthalic acid.

    --or--

    Positron emission tomography, also called PET imaging or a PET scan, is a diagnostic examination that involves the acquisition of physiologic images based on the detection of radiation from the emission of positrons. Positrons are tiny particles emitted from a radioactive substance administered to the patient. The subsequent images of the human body developed with this technique are used to evaluate a variety of diseases.

    A linear polymer, High Density Polyethylene (HDPE) is prepared from ethylene by a catalytic process. The absence of branching results in a more closely packed structure with a higher density and somewhat higher chemical resistance than LDPE. HDPE is also somewhat harder and more opaque and it can withstand rather higher temperatures (120° Celsius for short periods, 110° Celsius continuously). High density polyethylene lends itself particularly well to blow molding.

    Google is your friend!

    Well, if your are referring to plastics, then it's PP for polyproylene, NOT "PP5".

    The complete list:

    * Type 1 - PETE Polyethylene Terephthalate (PET)--Soda & water containers, some waterproof packaging.

    * Type 2 - HDPE High-Density Polyethylene--Milk, detergent & oil bottles. Toys and plastic bags.

    * Type 3 - V Vinyl/Polyvinyl Chloride (PVC)--Food wrap, vegetable oil bottles, blister packages.

    * Type 4 - LDPE Low-Density Polyethylene--Many plastic bags. Shrink wrap, garment bags.

    * Type 5 - PP Polypropylene--Refrigerated containers, some bags, most bottle tops, some carpets, some food wrap.

    * Type 6 - PS Polystyrene--Throwaway utensils, meat packing, protective packing.

    * Type 7 - OTHER Usually layered or mixed plastic.--No recycling potential - must be landfilled.

    Just checked with Snopes because I also used those bottles again and again- froze 'em, left them in a hot car etc etc---------they say nonsense--not true.
    Whew--guess it's still my pig like appetite causing my weight gain!!

    I know when you heat food in a microwave it's not good to leave it covered with plastic film. Use a glass cover or a plastic utensil designed for that purpose.

    apparently the film can emit stuff when heated that gets in the food.
