Product Description
Size: 12 Pc. Value Pack
The Rubbermaid 12 Piece Premier Food Storage Set contains (2) 1.25 cup, (2) 2 cup, (1) 3 cup, and (1) 5 cup containers with lids. Rubbermaid Premier Containers are made with Tritan™ plastic that resists stains and odors. Plus, Premiers have Flex & Seal™ lids that are easy to seal and remove. Part of the Easy Find Lids system, Premier lids snap to bases and other lids so you will not have to search for lids again and nest together to take up less room in your cabinets. The crystal clear bases are perfect for easily seeing the contents of the container and the square shape allows for easy stacking and storage in the refrigerator. The new Rubbermaid Premier food storage containers are BPA free.
CUSTOMER REVIEW
To start with, let me say I realize this review is a little over the top. I mean after all, we are talking about a cheap little container we use to store left-over macaroni. That being said, if you're like my family we end up storing, heating, and washing these containers a lot and we want them to clean up easy, not warp or crack in the dishwasher, and above all, to be safe (especially for use when my wife is pregnant and for storing or heating food for our children).
The original Premier line was the only plastic food storage product I've ever owned that didn't stain when it held tomato sauce. It's wasn't just tomato sauce: all kinds of berries in sugar, purple cabbage, beets, you name it we've stored it. They just didn't stain. They were hard, durable, and the lids were really easy to put on and take off. Microwaving and dishwashing did little to the appearance (they dull slightly but it's barely noticeable). Easily the best product of its kind I'd ever owned.
And one day I threw them all away.
When my wife and I started our family we took a good survey of the science and decided that the health risks associated with BPA were probably real. We are both very analytical engineers who did way too much research into this. We decided that while the risks to adults were inconclusive there was serious indicators that BPA's endocrine disrupting aspects were very likely a health risk for babies, particularly in the early days of fetal development (one large manufacturer of BPA now refuses to sell it for use in infant products). We decided to get rid of any polycarbonate food containers made with BPA and so the Premier (which contained BPA) got tossed out. We switched to the Easy Find Lids line which was good, but not as good as the Premiere line.
In of March 2010 Rubbermaid introduced a new line of Premier food storage containers that are BPA free. These have red lids, a swirl pattern in the plastic and "BPA Free" stamped on the bottom. These are made using the "Tritan" branded co-polymer manufactured by Eastman. Eastman has specifically developed Tritan to avoid the health risks associated with plastics made with BPA. So there are two questions: Is it safe? And does it work as well as the old Premier line?
Is it safe?
The answer appears to be yes, and I think Eastman has done a good job of publishing their testing methods and using reputable outside research to validate that Tritan is very safe. It passes (of course) the basic toxicity test and skin testing (to their great credit Eastman has published their testing methods for peer review). More importantly none of the monomers used in manufacturing (there are three) interact with the endocrine system. To be specific they were tested by the Robert Wood Johnson Medical School for estrogen and testosterone binding (there was none). It was further subjected to both Ueterotrophic and Hershberger assays by Wil Research Laboratories. The uterotrophic assay test for estrogenicity (basically "does it imitate estrogen") on both immature and ovulating female rats. The Hershberger assays test for androgen affects (most notably testosterone). In both cases there were no affects. (BPA for example has demonstrated BPA-induced uterotrophy in rats in testing done by the National Institutes of Health.) In short, it does appear that pregnant women and babies can safely use these products: it should not disrupt natural hormonal activity.
Does it work?
In most cases Tritan is better than polycarbonate and better than other BPA free alternatives such as transparent ABS, cyclic olefin, and impact modified acrylics. About the only thing that the "old" Premier was better at was heat resistance. What distinguishes Tritan from other co-polymers is that it combines hydrolytic resistance, heat resistance, stress tolerance and chemical resistance. Which is to say you can clean in the dishwasher over and over without it warping or cracking. A home dishwasher attacks dishes with heat (up to 70c) chemical detergents, water, and abrasion (when overpacked). Tritan has a transition temperature of around 110c (just enough to let you safely sterilize baby bottles made from it) far above the temperature of even commercial dishwashers. Tritan is also less likely to warp or crack under stress than polycarbonate. So whereas the old Premiere might crack or warp after a dozen runs in an overfull dishwasher, the new Premier can survive hundreds of such runs. It's high chemical resistance not only protects it from detergents it means you can store tomato sauce in it. In short it's generally better than the old Premier line except that if you leave both too close to the stove, the new Premier will melt first. So don't do that.
I've tried them out myself and I have to say the new Premier line is probably the best plastic food container line out there. I don't particularly care for the swirly lines, but aside from that I really like them.
