Very interesting tradeoff between packaging and shipping. Per their website FAQs... Why isn’t my bottle of Gorilla Super Glue filled to the top? For high performance and usability, the adhesive needs to be protected from air. One way to keep the air out of the adhesive is by packaging in thick plastic bottles. If the thicker plastic bottle was completely full of adhesive, it would be too hard to squeeze the glue out of the bottle. https://gorillatough.com/product/gorilla-super-glue/#product-details-accordion
Interesting. Maybe that explains why my tiny bottles of Krazy Glue always dried up after the 2nd/3rd use.
OK...but why not 2/3 full as opposed to 1/3 full? Inquiring minds want to know... Maybe the 'Gorilla' doing the testing says it has to do with viscosity and liquid dynamics...all top secret stuff !
I'm not buying it! Contradicting statements in that paragraph. "Adhesive needs to be protected from air" yet the bottle is filled with 2/3 air??? As for getting the glue out, you need VERY LITTLE CA to get the job done so you don't need to get that much out. Plus it's hard to get liquid out of a full bottle???!!! BS! If so, all those bottles of liquid in the supermarket need a redesign! I've used just about all brands of CA in years of building R/C airplanes and none come that empty.
Prior to the GG website, saw this comment on Reddit regarding glue level... "Oooo oooo I know this one, first off you should see on the front label of that gorilla glue a line that indicates the fill line, (I believe for this size it’s 20g) The large amount of air space prevents the glue from spilling out while using and pulls the glue back in to the bottle so it doesn’t dry on the nozzle and seal it off when you stop squeezing. I love gorilla glue for this reason. I used to hear it all the time that “this glue is only half full” but you’ll find that it’s compatible amounts you get from other companies however I’ve never had issues with the nozzle clogging with this design" I've thought that for a while with higher shipping-carrier costs. So many products in larger than needed container or package. Maybe due to higher economies of scale for minimizing the number of different packaging sizes? No doubt some marketers - manufacturers use larger packaging for projecting "getting more of something" -- you gotta love that 1/3 fill line.
Honestly I wish they made smaller bottles of super glue, I don't use enough of it and it usually goes bad before I finish the bottle. I wouldn't mind paying less and having only 5 grams! I know they have tiny metal squeeze tubes, but I think those are single use or just about, not as contrôlable as the regular plastic bottles.
The same idea on the container size likely applies to different size boxes. And you are not talking about enough of a weight difference to make an appreciable difference in shipping.
It's not the weight but the volume. Weight and volume are both factors in determining shipping costs. That's why all the shipping companies ask you for your box dimensions.
Density is what matters. Which IS determined by weight and volume. At least that's what they told me at every transportation company I worked at. All I am saying is there is likely not an appreciable savings having to re-configure a production line and keep numerous sizes of containers or boxes to ship them in for the size these are.
To be honest, I wouldn't call that "very small nondescript print." It's actually as big or bigger than most of the rest of the print on that label.
Does anyone know of any other Gorilla Glue products that use the same bottle? Or other volumes of the super glue? If they don't use the bottle elsewhere, then the "economy of scale" goes out the window.
Late as usual. I've used the same Gorilla super glue with the blue label for a long time now. Every bottle I have purchased is filled like that. There are other versions including a gel version (green on the label and cap) and it and the other versions I have seen come filled to the same point. I'm actually okay with the bigger size of the bottle vs the fill just because it's easier to handle with my big goofy hands. For the most part I have been pleased with how it works but it's not always the best glue for the job depending on the materials used. The fumes can and will cause fogging of the model surface in certain applications so beware of that. the only other issue I have had with it was I bought a bottle and when I opened the package, the glue had solidified. The store where I got it replaced it no question. I can only guess the bottle didn't seal properly at manufacture or maybe it had just been on the rack in the store that long, who knows. Another tip I learned from MK is store it in the freezer.
I'm wondering if the bottles, half filled with glue and half with what is assumed to be air, may actually be filled with dry nitrogen. Super glue needs moisture to cure ........ that moisture is typically in "normal" air. If the bottle has dry nitrogen in it then if only one drop of glue leaves the bottle then only one drop of "normal" air enters the bottle. I stand a good chance of being wrong ............ buuuuuuuuut I'm wondering.
