Product packaging must be appealing to people in order to attract their attention. If your product looks just like everyone else's, people might just pass right by it until they find one that attracts their attention. So the key is to be unique. Packaging is purposely designed to hold and protect the product but aside from that it can also be a powerful selling tool.
So try to be unique in your packaging and at the same time, try to keep it simple. You want to get your message out there and provide a product that is easy for your customers to use. Just make your packaging memorable and you'll see the difference it make to your sales.
