To protect goods
       It can be said that the essential function of all packaging is the same, that is, to protect the packaging, so the primary effect of food packaging bags is to protect food. In the whole process of food from being produced to being purchased by customers, various external factors will affect it. What food packaging bags have to do is to protect the quality of food and prevent problems such as evaporation, penetration, bumping, and kneading during this process.
       Convenience
       As mentioned above, food packaging bags are products that are used in the fast-paced urban life, and are products that are born to facilitate the lives of the masses.
       Avoid danger
       Packaging can play an important role in reducing shipping safety hazards. Bags also prevent food from going back into other products. Food packaging also reduces the chance of food being stolen. Some food packaging is strong and has anti-counterfeiting labels, the effect is to protect the interests of merchants from loss. The packaging bag can have labels such as laser logo, special color, SMS authentication and so on. To prevent theft, other retailers put electronic surveillance tags on food packaging bags, which are demagnetized when customers get to the store's exit.
       Improve your image
       In today's life, corporate image and corporate culture are both a potential value of an enterprise. The combination of food packaging bags and corporate image can improve visibility and expand corporate influence. For example, Coca-Cola, Lay's, Nongfu Spring, etc. all pay special attention to this.
