Food packaging bags are a type of packaging design. In order to preserve fresh food in life, product packaging bags are made. Food packaging bags are film containers that are in direct contact with food and are dressed to protect food.
Food packaging bags are produced with food plastic film, generally more than 2 layers of composite material packaging bags.
What is the role of food packaging bags?
1 Physical protection
The food stored in the packaging bag should avoid extrusion, shock, vibration, temperature difference and other phenomena.
2 case protection
The outer shell can separate the food from oxygen, water vapor, stains, etc. Preventing leakage is also a necessary factor in the packaging design. Some packages include desiccants or release agents to extend shelf life. The removal of air from vacuum packaging or bags is also the primary method of food packaging. Keeping food clean, fresh and safe within the shelf life is the main function of the packaging bag.
3 The same packaging
Packing small items of the same kind in one package is a great way to save on bulk. Powders and granular objects are to be encapsulated.
4 Convey the message
Packaging and labels tell people how to use, transport, recycle or dispose of packaging or food.
Marketing often uses box labels to encourage potential buyers to purchase an item. Packaging design has been a very important and changing phenomenon for decades. Marketing communications and graphic design are applied to the outer box and (for some reason) to the highlights of the sales display.
Packaging can play an important role in reducing transportation safety risks. Food packaging also prevents food from being classified as other commodities. Food packaging can also reduce the likelihood of stealing food. Some food packaging is sturdy and has anti-counterfeiting signs, which play a role in protecting the interests of merchants from loss. Labels such as laser logos, special colors, and text certification can be affixed to the packaging bags. In addition, retailers, in order to prevent theft, put electronic surveillance tags on food packaging bags so that consumers can get the store exit and eliminate the magnetic force.
Packaging can be easily added, loaded and unloaded, stacked, displayed, sold, opened, repacked, used and recycled.
