1. Physical protection of the food stored in the packaging bag shall avoid squeezing, collision, vibration, temperature difference and other phenomena.
2. The protective outer shell can separate food from oxygen, water vapor, stain, etc. and prevent leakage is also a necessary factor for package design.Some packages include desiccant or deoxidizer to prolong shelf life.The vacuum packing or the air in the packing bag is also the main food packing method.Keeping food clean, fresh and safe during its shelf-life is the primary function of packaging bags.
3. Encapsulating or loading small items of the same type into a package is a good way to save volume.Powder and granular objects need to be encapsulated.
4. Conveying information on packaging and labels to tell people how to use, transport, recycle or dispose of packaging or food.
5. Box labels are often used in marketing to encourage potential buyers to buy products.Packaging design has been an important and ever-changing phenomenon for decades.Marketing communications and graphic design are applied to the packaging box and (for some reason) the highlights of the sales presentation.
6. Safe packaging can play an important role in reducing transportation safety risks.Packaging also prevents food from going to other products.Food packaging also reduces the likelihood that food will be stolen.Some food packages are strong and have anti-fake labels, which protect the interests of merchants from losses.The bag can have laser logo, special color, SMS authentication and other labels.In addition, retailers place electronic monitoring labels on food packages to prevent theft, and customers are taken to the store's exit for demagnetization.
Convenient packaging may be available for purchase, loading, unloading, stacking, display, sale, opening, reloading, use and reuse.
8. Partial control of individual packaging helps to accurately control the overall situation.Food packaging, such as salt, can be used to keep track of inventory.It also makes it easier to count recent sales, such as milk companies sending and recycling milk bottles, rather than letting consumers fill them themselves
