Two colors cream tube is often used for packaging two formulas. To distinguish them, their colors will be made in different. The tube as the photo attached is outside tube transparent and inside tube pink color. The cap’s outside is acrylic material high transparency and inside is PP pink color.
The nozzle of the tube is bigger than the normal tube, because there should design the squeezing out holes from inner tube and outer tube.
This two colors cream tube was made because of two reasons, one is for nice looking, another is for function. Because when the formula mixed well, the different colors can’t be squeezed out orderly as we thought, there are two colors, but looks not so beautiful. By using the two colors cream tube can get orderly color mixing result, making people very happy after seeing the formula squeezing out.
The requested length of the tube should refer to the outer tube, the inner tube is often made longer than the outer, just to operate conveniently during the tube production, and this also guarantees airtightness of the tube’s tail-sealing.
