What are the norms for the design of food packaging bags

1. Strength requirements

Packaging can prevent food from being damaged by various external forces during storage and stacking, such as pressure, impact and vibration. There are many factors that affect the strength of food packaging design, including the mode of transportation (such as by car, by plane, etc.), the stacking form (for example, multi-layer stacking is required), and in addition, environmental factors need to be taken into account, including natural climate and hygiene environment.

2. Barrier requirements

Barrier property is one of the important attributes in food packaging design. During the storage of many foods, due to poor packaging design, food quality problems are prone to occur. The barrier requirements for packaging design are determined by the characteristics of the food itself. Its characteristics include external blocking, internal blocking or selective blocking, etc., involving air, water, grease, light, microorganisms, etc.

3. Breathing requirements

There are many foods that still maintain their respiratory function during storage. Therefore, the design material or container of this kind of food packaging bag is breathable or can control breathing, thereby achieving the purpose of preservation.

4. External requirements

When designing food packaging bags, it is also necessary to pay attention to some external requirements, reflecting the characteristics of the product through packaging. All of these are the external visualization and expression forms and means of food.

5. Safety Requirements

There are also safety requirements for packaging bag design, including hygiene safety, handling safety, etc., and it is also necessary to reflect the safety of use. The main point is that the materials used for packaging bags should be environmentally friendly and hygienic, rather than those that may cause harm to the human body. In terms of packaging design technology, efforts should be made to keep the nutrition, color and taste of processed foods unchanged as much as possible. At the same time, the safety of consumers when taking them after shopping should also be taken into account. Safety in use is to ensure that consumers are not harmed during the opening and consumption process.

Of course, apart from the above, there are many inherent requirements when designing food packaging bags, such as heat resistance requirements, light resistance requirements, breakage resistance requirements, moisture-proof requirements, etc. Moreover, the outer packaging of food can also serve as a promotional method for food. On the outer packaging, we can reflect the characteristics of the food, the way of consumption, and various nutritional components, etc. Thus playing a role in promoting the products.
