Justipedia explains Trade Dress
The trade dress is the features of a product that make the product unique. Problems can arise if one company packages or creates a product that is too similar to the product of another company.
Trademarks exist so that companies can have exclusivity for their products in the market. This prevents intellectual property theft and creates an incentive for business to create their own products. This is why it can be a cause of action if one company infringes upon the trade dress of another.
