The close relationship between food packaging and food has long been known. Food packaging is like food "protective clothing", not only has the function of carrying and protecting food, but also has the function of facilitating food storage, transportation and promoting sales. At the same time, with the continuous improvement of people's living standards, food safety issues have gradually become the focus of attention, which also puts forward higher requirements for the safety of food packaging, making food packaging enterprises always put safety in the first place in the design, function realization and safety testing of food packaging.
Food packaging design should have innovative design concepts, reasonable design according to the positioning of consumers. At the same time, for some special consumer groups, such as children, we should also pay attention to the safety design of food packaging, such as the selection of environmentally friendly packaging materials, the packaging structure should be as simple as possible, and at the same time, it is required to meet the needs of children and physical characteristics to prevent accidental injury to children.
In addition to innovative and safe design, the functional realization of food packaging is also very important, especially with the increasing demand for fresh food in the consumer market, food packaging with fresh-keeping function has gradually become popular. Especially for the current demand for fresh fruits and vegetables, modified atmosphere packaging, film packaging, antibacterial packaging and other technologies have been introduced, providing more protection for the safety of fresh fruits and vegetables.
In order to further ensure the safety of food packaging, relevant personnel have also done a lot of work in food packaging safety testing. For example, in order to eliminate consumer panic, some researchers have evaluated the potential risks of DEHP in food plastic packaging materials, further improving consumers' awareness of the safety of DEHP.
At present, the state also attaches great importance to food packaging safety, and has issued a series of policies and regulations related to food packaging safety. Food packaging enterprises should strengthen the safety awareness of food packaging, establish the concept of "food packaging is equivalent to food", and add a lock to food safety.
