Bottles made of Polylactic Acid (100% from field corn); Biodegradable

Fresh whole foods deserve fresh eco friendly zero leaching packaging. Fresh raw milk is 100% pure whole food from nature, as are the new bottles developed by Organic Pasture Dairy Company. In conjunction with NatureWorks LLC, OPDC will begin manufacturing a clear bottle made of PLA ( Polylactic Acid), a polymer with similar characteristics to traditional thermoplastics but made from 100% field maize (corn). That's right, PLA has zero potential phyto-chemical leaching. It is not made from petroleum fuels or chemicals like all other plastics. PLA is bio-degrable and compostable given warmth, bacteria, moisture and time. The container itself when composed becomes a living food for living things, not land fill filler.

But Natureworks LLC is a Cargill company - will the corn be organic, conventional, or genetically engineered?

if you are not allergic to corn. Corn is one of the fasted growing food allergies. I can't have anything wtih corn starch, corn syrup or anything like that.

i.e. you may not be allergic to the starch or syrup itself, but to some trace ingredient found in the natural product. The plastic is so different in its chemical properties (mostly solubility) that it may be entirely free of the allergen. Of course, I'm not a doctor, so don't take my word for it. Only testing will tell. But I'd be real surprised if polylactic acid (which could just as well be named polylactone, FWIW) is an allergan. It breaks down to lactic acid, which your body produces naturally -- when it builds up in your muscles from long exercise, it causes muscle cramps, but at lower concentrations it's a harmless part of your body's normal metabolic 'exhaust'.

For comparison, latex rubber can be made hypoallergenic by repeated washing, which removes traces of plant proteins. When the onset of AIDS caused demand for surgical rubber (gloves, condoms) to skyrocket, mfgrs tried out a faster process in which the rubber was washed only twice, instead of three times, as previously. This resulted in a sharp increase in cases of latex sensitivity. Some hospital workers had to quit their jobs because the dust from latex gloves was everywhere -- they literally couldn't walk into a hospital without suffering a reaction. What would seem like a tiny amount of a contaminant made all the difference.
