Design the package based on the users’ needs, desires and expectations: The buyers focus on stylish and user-friendly packaging, which directly connect with the product they seek.
Use the appropriate messages and design: The packaging should inform potential customers about the product and the reason they should choose it. It is therefore necessary to avoid the use of large texts and complex designing. Everything in moderation!
Carefully select colors and fonts: The packaging should be impressive, but not fancy. The colors should complement and enhance the product,
instead of downgrading it. Choose a font that is distinct and readable and which suits with the brand logo.

Make sure packaging is effective for each distribution channel: The primary purpose of packaging is to stand out on store shelves and if the product is available online it should be suitable for online shopping as well.
Fit packaging over the product and make it user friendly: The packaging should be practical in terms of shape, size, use and materials. It should also be durable, functional, easy to open, close and transport, and should incorporate mechanisms to facilitate the proper discharge of the product. If the product is premium, consumers will expect appropriate packaging.

Be environmentally friendly: Avoid unnecessary materials and use recyclable / renewable materials. Design a package that ensures the integrity of the product and which does not produce a lot of waste.
Create a package that protects and preserves intact the product: Food safety is a predominant concern for consumers and both the US 
authorities and the EU have set strict regulations for this. Subsequently, packaging should retain food pure and fresh.
Create a package that facilitates distributors: Draw a package that is easily stacked and stored, making it easier for retailers to place the product on the shelf and in their warehouses.
