The role of product packaging design is to protect the product, beautify the product, and promote the product. It is also a technical and artistic means to increase the commercial value of the product. Packaging is a dependency of the product and an important means to realize the value of the product.

If putting the product in a particular package works best, don't limit yourself to this one solution. This kind of soap is best equipped with a box, but it is not an ordinary box that can only open at one end.

Make sure your design makes up for the deficiencies of your internal products. In this case, the outer packaging is as simple and natural as the inner product.

Think about what happens when a person interacts with their product. Assume that this product is a pair of luxury slippers. Because it is a luxury product, the product comes with a nice dust-proof lace, and it is placed in the box.

​Why do you pick this particular brand? Is it because of an impulse, or because of real needs? Maybe this thing is interesting, so you bought it. Like buying a shampoo, of course you may need a bottle of shampoo, but do you really need a brand that looks beautiful and expensive shampoo? That may not be so! But you did buy this bottle of shampoo because it made you feel fashionable, even if this brand of shampoo was thrown into a discount basket.
