How to seal a bag and make it air-tight!

Reused Plastic Bottles Can Leach Toxic Chemicals

You know many advocates who recommend not reusing bottles made from plastic #1 (polyethylene terephthalate, also known as PET or PETE), including most disposable water, soda and juice bottles. According to National Geographic’s The Green Guide, such bottles may be safe for one-time use, but re-use should be avoided be cause studies indicate they may leach DEHP—another probable human carcinogen—when they are in less-than-perfect condition. Repeated re-use of such bottles—which get dented or nicked through normal wear and tear and while being washed—increases the chance that chemicals will leak out of the tiny cracks and crevices that develop over time.

“Luckily” polyethylene terephthalate (PET) is recyclable; up to 30% in 1996.

But here’s what can do with the bottle top.

Cut up a disposable water bottle and keep the neck and top, as in photo.

Insert the plastic bag through the neck and screw the top – to seal.

The bottle is made to be air-tight, such that water will not leak, the secret lies with the design of the top and screw!

This great idea was forwarded to us by Gillian who, unfortunately, was not able to identify the innovator.
