What is a food packaging bag? The packaging bag will be in contact with the food, and it is the packaging film used to hold and protect the food. Generally speaking, packaging bags are made of a layer of film material. Food packaging bags can reduce food damage during transportation or in the natural environment. In addition, food packaging bags have different styles and types, which can be easily Divide the product categories locally, and some special specifications need to be paid attention to when designing food packaging bags.
1. Strength requirements
Packaging can prevent food from being damaged by various external forces, such as pressure, shock, and vibration, during storage and stacking. There are many factors that affect the design strength of food packaging, including transportation methods (such as trucks, airplanes, etc.) and stacking methods (such as multi-layer stacking or cross stacking). In addition, environmental factors, including natural climate and hygienic environment, need to be considered.
2. Barrier requirements
Barrier is one of the important attributes in food packaging design. Many foods are easy to cause food quality problems due to poor packaging design barriers during storage. The barrier requirements of packaging design are determined by the characteristics of the food itself. Its characteristics include external barrier, inter
nal barrier or selective barrier, etc., with air, water, grease, light, microorganisms, etc.
3. Internal requirements
The internal requirements of food packaging bag design refer to the need to ensure the quality and data of the food when de
signing the packaging bag to meet its specified technical requirements.
4. Nutritional requirements
The nutrition of food is gradually reduced during packaging and storage. Therefore, the design of food packaging bags should have the function of facilitating the preservation of food nutrition. The most ideal state is that the nutrition of the food can be locked through the design or composition of the packaging bag, which is not easy Drain.
5. Breathing requirements
There are many foods that maintain respiratory function during storage (for example, fruits, vegetables, etc.). Therefore, this kind of food packaging bag design material or container needs to have air permeability, or be able to control breathing, so as to achieve the purpose of keeping fresh.
6. External promotion requirements
When designing food packaging bags, you also need to pay attention to some external requirements. The external design of the packaging bag is a good means of food promotion. It can promote the characteristics of the food, the way of eating, the nutrition and cultural meanings, etc. on the packaging. . Necessary information promotion and image promotion or color marketing, promotion and other structures. These are all external visualization and expression forms and marketing methods of food.
7. Safety requirements
There are also safety requirements in the design of packaging bags, including hygiene and safety, safe handling, etc., and also need to reflect the safety of use. The part of health and safety is mainly that the materials used in the packaging bags should be environmentally friendly and sanitary, rather than materials that are harmful to the human body. In terms of packaging design technology, the nutrition, color and taste of processed foods should be kept unchanged as much as possible, and the safety of consumers after shopping should also be included. The use of safety is to ensure that consumers are not harmed during the process of opening and eating.
In addition, the food packaging bag design has some other requirements in addition to the above common requirements, such as the heat resistance, depth, shatter resistance, moisture resistance and other special requirements of the material, which are all designed according to the characteristics of the food. . Of course, it is also necessary to pay attention to the degradation performance of the packaging material in the natural environment when designing the packaging to avoid environmental hazards.
