Bottle cap materials
what metal are bottle caps made of? — Preceding unsigned comment added by 24.15.47.148 (talk) 12:32, June 21, 2005 (UTC) For Pet bottles caps are made by using HDPE & LDPE. —Preceding unsigned comment added by 124.43.232.239 (talk) 08:59, 12 May 2011 (UTC)

bottle caps and closures
This subject is in need of editing. Many glass bottles are capped with aluminum or plastic closures. Most plastic closures can be recycled. A range of sport caps are used on sport drinks.

Then there's the claim that twist-offs are the dominant form. Maybe in the USA, bucko, but out here in the vast majority of the world you can go for twenty years and see nary a one - and those that ARE around are on stuff imported from the USA. 86.11.124.189 15:44, 28 July 2006 (UTC)

Physical characteristics
How much does a bottlecap weigh? -josteinaj, 19.feb.06, 00:58 UTC

Some answers to the above questions
I found a source on crown cap material: 

Crown caps apparantly are made from tin plate.

I also found a wholesale supplier selling bottle caps: 

1 gross (144) of bottlecaps is .75 pounds; 10,000 bottlecaps is 52 pounds. WOW TKS SO MUCH — Preceding unsigned comment added by 110.92.124.244 (talk) 01:18, 26 February 2018 (UTC)

From this we can derive that a bottlecap is about 2.3-2.4 grams in weight, or .08 oz. --Soundwave106 14:31, 20 July 2006 (UTC)

Twist-off caps
Added the fact that twist-offs are widely used in Australia. They are virtually unknown in the UK (where I live), so it was a bit of an eyebrow-raiser to go to Australia and see people open bottles with their bare hands! 217.155.20.163 22:23, 31 March 2007 (UTC) PET caps are made by using H.D.P.E. & L.D.P.E —Preceding unsigned comment added by Prageeth666 (talk • contribs) 09:41, 12 May 2011 (UTC)

Bottle cap image
The old bottle cap image was deleted for lacking permission information (see .) A new bottle cap image should be added. -- Hi  Ev  10:46, 21 August 2007 (UTC)

Inappropriate business use
The article contained what appeared to be substantial material from one company, directing buyers how to use their products. Part of that and a plug for Colnect were removed. 76.102.1.193 (talk) 23:51, 16 June 2012 (UTC)

Reverted what appeared to be substantial recent material added by a series of edits from one company, extolling the virtues of a product and offering samples. 162.136.192.1 (talk) 15:27, 29 May 2015 (UTC)

Screw Cap
Is "Deus exes" an actual brand of beer, or do we mean "Dos Equis?" 66.67.103.126 (talk) 01:37, 20 March 2014 (UTC)

As currency?
When we were kids the YMCA summer camp/day care service would bus us to the local theater and pay with bottle caps. We were probably encouraged to bring in bottle caps, but I don't remember that. We usually didn't see new or popular movies, but that could have been because there wasn't enough for kids. A lot of the movies were Japanese giant monster movies and Ultra-Man like scenarios. This would've been in the late 80s/early 90s. What was going here?--184.63.132.236 (talk) 03:49, 19 June 2015 (UTC)

Reference to Fallout video game seems inappropriate.
The game itself has nothing to do with bottle caps, and someone coming to this page would likely not find this bit of information relevant or useful. If a reference to the Fallout video game is allowed to remain, then should we also find every single other TV show, movie, or theatrical play that includes bottle caps in some way to include on this page? What is so special about this game?

I think this section should be removed. — Preceding unsigned comment added by 143.85.5.26 (talk) 18:40, 31 May 2016 (UTC)

-Well, for starters, Fallout was the reason I even came to this wiki page, looking for the actual weight of a modern [| Crown cork bottle cap.]. Bottle caps are the currency of the game, and are such an icon of the series that you can get Fallout bottle cap keychains, necklaces, earrings, shirts with bottle cap references, you name it. In the Nuka-World add on for Fallout 4, there's even an anthropomorphic bottle cap mascot for a product called "Nuka-Cola". In short, bottle caps are a BIG deal in the Fallout universe, and seeing as the game grossed $750 million in its first week of sales, the game itself is a big deal. To omit it from the bottle cap wiki page seems like it would be a rather large oversight. — Preceding unsigned comment added by 71.35.167.87 (talk) 20:49, 9 September 2016 (UTC)

collecting for charity
In Europe schools and other places often collect caps for charity. This needs a section, ideally explaining why caps are so desirable (what's special about them that charities want them?). Malick78 (talk) 10:04, 3 December 2019 (UTC)
