How do small and medium-sized enterprises develop product of cosmetics.
1. Don’t make too many products. There are more and more small and medium-sized cosmetic manufacturers. Their products almost cover all kinds of cosmetics. You can see that there are many products, but in fact, they have many disadvantages. The first one is that the sales volume is not necessarily high. The 80/20 law states that 80% of the benefits of any entity come from 20% of the products, that is, 80% of the products can only contribute 20% of the benefits, which is not economic.

This is changing the traditional concept of plastic composite tube packaging only for simple packaging of low-grade products.
What standard should cosmetic tube have in respect of oxygen resistance
