Today i will talk about what is the difference between five-layer tube and two-layer tube.

First, Please see this picture, it is a five-layer tube, we can see that it includes outer layer, bonding layer, insulating layer, bonding layer and inner layer.

Five-layer tube has much better gas barrier properties and toughness, it can prevent other gases sinking into it. In other words, it also can effectively stop dissolved aromatic compounds and other components sinking out effectively.Five-layer tube is more adhesive than two-layer tube. It can be filled with some liquid foundation, such as eye cream, sun cream and so on.

However, Two-layer tube is cheaper than five-layer tube, so you can choose two-layer tube if you prefer low price. Two-layer tube can be filled with some shampoo,such as face wash etc..
