What percentage of food grade polyethylene foam is used vs. polyester? And which part exactly is the polyester used for?

It's about half food-grade polyethylene and half polyester. The mattress meets all flammability requirements without needing any flame barriers or other flame retardant chemicals. It's also completely waterproof without needing vinyl or perfluorinated compounds. It's hygienic in that anything wipes right off, and without staining. It is firm (the way the Consumer Products Safety Commission wants it). It's also firm at the edges (for jumping toddlers) with a snug fit. It is free of known allergenic materials like latex. It does not contain any polyurethane foam or so-called soy-foam (which is polyurethane foam). It comes with a limited lifetime warranty and is durable and well-built, even though the whole mattress weighs only about seven pounds (which makes it real easy to bend over the edge of the crib and pick up the mattress and change the sheet). Healthy Child Healthy World recommends this mattress. And Lullaby Earth has won a ton of awards.

It should also be noted that 100% natural talalay foam does not really exist. Foam produced using the talalay process contains materials other than latex. While "100% natural talalay foam" is offered by many retailers, this label is a bit misleading. The "100% natural" refers only to the latex content of the foam and ignores the fact that the foam contains materials other than latex. If the product description in accurate then this would be a latex topper manufactured in the Dunlop process and would be more eco friendly with no "off-gassing"

Good grief Naturepedic's answer was annoying, not to mention cagey. All that lead-up made me feel like it was going to be something much worse between the cotton layers than it actually is. Why can't the company just say, "food grade polyurethane?"

Just another note I think this clears it up...#1 - PET or PETEFull Name: Polyethylene TerephthalateUsually clear or green, glossy, rigid containers that sink in waterClear and green soda bottlesCooking oil bottles, peanut butter jarsSalad dressing bottles and other food and drink containers

If speaking on a chemistry level, then yes I believe, polyester is derived from olefinic process too. I am not a chemist, but merely a consumer who would like to reduce waste. Since purchasing these bags I have not used any of the disposable plastic bags that markets offer you to bag your produce. If these bags were described as "be free from further disposable plastic bags usage" might be more helpful to you.

At Jarden Consumer Solutions (JCS), we are committed to producing trusted household products that meet or exceed applicable product standards. BPA is a key component in the production of polycarbonate plastics. Polycarbonates (PC) are used in a variety of applications in the appliance industry where strength, durability and clarity are required. BPA is also present in certain thermo set epoxies used in coatings, adhesives, paints, etc. Phthalates are primarily used in vinyl to make the material more pliable/flexible. A vast majority of our products are made from BPA free plastics such as Polypropylene (PP), Acrylonitrile-Butadiene-Styrene (ABS), Styrene-Acrylonitrile (SAN), High Impact Polystyrene (HIPS), Polyethylene (PE), etc. and inorganic materials such as glass, which do not contain BPA. Currently, Polycarbonates (PC) continue to be recognized as safe for food contact applications by the United States Food and Drug Administration (FDA). JCS purchases Polycarbonates (PC) from trusted suppliers, who monitor to ensure what they sell complies with all current federal, state and local health and safety regulations.

I don't know is the only answer I have. You need to ask the manufacturer. Some plastics withstand heat better than others.

Some good info on plastics for food is found here. But essentially it says plastic bags used for food are OK. http://www.seventhgeneration.com/learn/blog/safer-kitchens-bag

Yes, this is 100% food grade silicone but it is not 100% silicone. Please read FAQ for an explanation by the manufacturer of our silicone products. Sorry for answering your question late. I just came back from vacation and I did not have access to my computer while I was away.

The foam is dense. I put it under a mattress cover to protect it from liquids and myself from the used mattress. I sleep comfortable with it. It is much better than the egg carton type.

Do your research! I believe food grade is safe for humans according to the FDA. I haven't tried it yet. I'm looking for more complete info first.

This is what I found online about soy foam which is what is in this mattress along with the latex. But I would suggest you google it also to see what you can find on the subject. "The current market is in a craze over soy-foam. Marketed as being better for the environment than polyurethane based foams, we did some research to see what this 'green' foam was all about. As it turns out, Soy foam is not much better than poly-based foam, and some people would argue that it has the same impact. Soy foam is actually made the same way as the polyurethane based foam, with 20% of the mixture being replaced as soy product. So the foam is 20% soy, 33% isocyanates, and 47% polyurethane.? Due to the polyurethane content, the foam still requires the toxic flame retardants, and the foam contains the same level of isocyanates. Currently, soy foam also biodegrades at the same rate as poly-based foam. The reason for the low percentage of soy content is that when soy is present at higher levels it produces an undesirable, burnt smell. In addition, the use of pesticides and fertilizers on the soy crop have a negative impact on the environment, as do the mono cultures in which soy is planted. Soy is such a diverse and valuable food source that it may not be used best as a plastic substitute."

These other reviewers obviously do not know the difference between plastic and other materials. It's neither (plastic would melt with the heat); it's actually an FDA approved polycarbonate dome. You will not be disappointed.

LDPE is one of the 7 plastics listed by the FDA as food safe. I am guessing you are looking for food grade plastic for aquaponics. Unfortunately these manufacturers do not publish the info we are looking for. The 7 plastics considered food grade are PETE/PET, PVC, HDPE, LDPE, PP, PS, and Grade 7 (other). HDPE(stiff), and LDPE(flexible) are the best choices for aquaponics, with PVC (white) plumbing. Hope this helps, it took me a bit to figure this out for myself.

I use 2% milk - you can use any type of milk but the low fat milk tends to froth better. Some people use soy as well.
