Is it illegal to copy the appearance packaging of other products?

It is illegal to copy the appearance packaging of other products. No matter what kind of patent is targeted at, unauthorized use without the consent of the patentee may constitute infringement. Generally speaking, if the design patent is valid and the annual fee is paid on time, then the patent is valid. As long as the products produced by the defendant are similar in appearance to the appended drawings (six pictures) of the design patent certificate, they can be regarded as infringement. Article 185 of the Civil Code intentionally infringes on the intellectual property rights of others, and if the circumstances are serious, the infringed person has the right to request corresponding punitive damages.
