Does anyone know with any certainty what the translucent white bags used to hold breakfast cereal are made of?
..and does anyone know where to buy the stuff in moderate bulk quantities?
I've been using cereal bags as a protector when working dents out of a finished (plated or lacquered) instrument and find that there's nothing that comes close to the durability of these things. Unfortunately, I can eat only so much cereal...
It's gotta be some sort of modified PVC. Yea... It's some tough stuff! I always have a roll of waxed paper by my dent machine... but I would buy a roll of the cereal box stuff if I knew where to get it. With no kids left at home we might eat eat a box of cereal every six months or so.

Liner
The liner is the inner bag that protects food inside its carton, keeping it fresh and able to maintain a lengthier shelf life.
For most Kellogg products, the liner is unfolded from a reel, and forms a bag around the cereal. The top and the bottom of this bag are then heat-sealed, and the bag is inserted into its appropriate carton.
You may be surprised to know that Kellogg's has a number of requirements that must be adhered to for liner materials, including:
• Shelf life; a liner must ensure that a product will maintain its freshness while sitting on the shelf (either in the supermarket, or in your pantry at home)
• Appearance; which is very important for a food product
• Peelable seal; so that the bag can be opened conveniently and easily
• Reclosability; to ensure that the bag can be re-sealed, to ensure the continued freshness of the product.
Liner bags are predominantly made of HDPE (High Density Polyethylene), which unfortunately is not a recyclable material. For this reason, Kellogg's is continually working towards reducing the amount of material that is used to manufacture the liners, whilst still maintaining our high level of product integrity, which meets each of the requirements listed above.

I found my answer on the Kellogg's (Australia) Cereal web site. Apparently Austrialians care what their Cocoa Puffs are packaged in:

Hmmmm..... Something is fishy here! HDPE IS reclyable... at least it is in the US. I still think these bags are an alloy... maybe consisting of mostly HDPE... but possibly contain a dab of other stuff to make 'em tough. McMaster-Carr has HDPE film but the thinnest is .004"... probably too thick for our purpose. Chuck, let us know where your research leads.
