Have you ever wonder what is the colored square box at the back of your skin care tube for?
At one of the blogger get-together recently, I learnt something new. Fellow blogger friends shared about the meaning of the small little square box that was found on the top edge crimp behind most skin care or product tubes. I was told that different color box bear different meaning.
Green: All natural
Red: Some natural, but most chemicals
Black: Only chemicals are used.
Black/Blue line: 100% chemical
Red Line: 50% chemical, 50% natural
Green Line: 100% natural
Well, after some digging online I found out that all this is not true 😀
So what exactly does the colored square box means?
It is referred as “eye marks”. Eye Marks is used in the manufacturing process in order to detect and align squeeze tubes. Normally these marks are printed on the area that will be trimmed off later. But because of the tube shape it is not necessary to trim it off. All colors are made from 4 colors in printing. Eye Mark is also used to make sure everything lines up. So yes, these colored box is just marks used in printing process, nothing else.
Corporate Color / Any Printing Color Used
Not sure if you notice this or not but I do. Most of the time the color used to print these square boxes are usually the brand’s corporate color or color from the printing. I remember freaking out upon seeing red square box on all my Clarins tube!
Some spread rumors saying these colored square boxes has something to do with the formulation of the product as well. That is not true. It is just a mark used on printing of the tube 🙂
If the printing at the back of the tube is silver, the color on the square box will most probably be silver too. If it’s white printing, the square box will be white most probably. I think you get the drill 😀
There has been countless information being spreaded on various platform with regards to the color square box that appear on various products. Most of these information claimed that different color represent the type of ingredient used or even product formulation.
These “eye marks” are also found on many different products and even newspapers printing uses the square as identifying marks. There is also quite a number of concern on toothpaste. Really? Toothpaste? Okay so I did some reading and found this.
Toothpaste tubes would be produced by one manufacturer but the toothpaste brands may get their tubes filled in the same filling factory as other brands. Photo sensors on the machines in the filling plants would need to know that whats on the tube goes in the tube hence the need for indicators.
Eye marks is also used to indicate to the machine that the tube is the right way up when being filled. So the next time you are thinking hard about the colored square box at the back of your skin care tube, just ignore it. It is mainly for printing purposes 😀
