According to this it takes about 50 tons of PE granules to make about 40 Kilometers of clingfilm.

Moar plastic manufacturing. Thickness of 2/10,000 of an inch. Plastic is crazy cheap and efficient compared to other methods.

Plastic bags. Full roll is 348 lbs which makes 35,000 bags.

If you're wondering about crude to plastic efficiency...

It takes about 0.4 gallons of crude oil to make one pound of plastic, which means that 11 million metric tons of plastic equates to approximately 9.7 trillion gallons of oil.

A nice copout answer from the US Government lol.

The U.S. Energy Information Administration (EIA) is unable to determine the specific amounts or origin of the feedstocks that are actually used to manufacture plastics in the United States.

This oil website even busts their chops on it lol.

This fact itself raises questions such as, “How many barrels of oil go into plastic packaging?” A question that is quite difficult to answer. The Energy Information Administration absolutely refuses to answer it, saying that it collects no data in this segment. Yet data from a few years ago, when the EIA still collected information about this, shows that in 2010 some 191 million barrels of LPG and NGL were used for the production of plastics along with 412 billion cu ft of natural gas. The liquids amount constituted about 2.7 percent of the country’s total petroleum consumption. Most of the natural gas used in plastics production was used as a fuel rather than feedstock.

Plastics production accounts for about 4 percent of global oil production. That’s according to figures for 2012, so now it may well be higher.

Some interesting glass to plastic energy efficiency info, not discounting their completely different use cases.

The total energy required to produce, package, and transport a 16 oz. PET container is 32 MJ compared to 34 MJ for a 16 oz. glass container – virtually the same. Producing a pound of plastic resin, however, uses nearly nine times the energy of producing a pound of glass. These comparisons assume the use of virgin glass.

I can tell you for certain it's more than two packs of Twix. A lot more.
