With increased public interest in green living, many food packagers combat negative public image by creating environmentally responsible packaging. Examples of this trend include the Poland Spring Eco-Shape Bottle and the Starbucks recyclable cardboard cup. However, many suppliers continue to use extra packaging, such as cards, to maintain a minimum level of food sanitation and product safety.
Food products that include cardboard in the packaging are fragile. The products may be easily crushed or dismantled and require the additional protection offered by the cards. Examples of food products that are shielded by cards are Almond Joy candy bars, Reese's Pieces candy and Hostess cupcakes.
Food packaging cards offer an additional layer of protection against environmental hazards, such as nearby spills. Product waste is thereby minimised. Additionally, paper cards with a wax layer prevent the intrusion of vapours and preserve the quality and taste of a product. However, not all cards contain a wax coating.
Clear packaging uses the white card as a background, which allows the nutritional information and ingredient list to be visible from the outside. This method is advantageous because it prevents ink from contacting the food product.
Card can be used as an alternative to plastic packaging materials, such as polystyrene. Food cards may be recycled with magazines and other glossy paper products.
Plating plays a influential part in the culinary arts. Stacks of books and entire courses have been written about the importance of food presentation, such as "Working The Plate" by Christopher Styler and "Food Presentation" by Michelle Valigursky. Although a white card is not an elaborate piece, the packaging material frames the food item. Dark chocolate looks darker; Dots candy buttons look more colourful. Cardboard packaging makes you want to eat the product and--more importantly--buy more.
