What are the internal requirements for food packaging from bag in box manufacturers
Internal requirements: the internal requirements of food packaging refer to the technical requirements of food packaging manufacturers to ensure the quality and quantity of food in their packaging through packaging and bag in box manufacturers.
Strength requirements: it means that the package can protect the packaged food from various destructive forces such as pressure, impact force and vibration force during storage, stacking, transportation and handling. There are many factors related to the strength of food packaging, including transportation mode, stacking form and environment.
Barrier requirements: barrier is one of the important properties in food packaging. Many food in storage and packaging, due to poor barrier, the flavor and quality of food change, and ultimately affect the quality of food. The barrier requirements introduced by the manufacturers of bags in boxes are determined by the characteristics of the food itself, including external barrier, internal barrier or selective barrier, etc. There are air, water, grease, light, microorganism and so on.
Respiratory requirements: some exported foods, such as fresh fruits and vegetables, still maintain respiratory function during packaging and storage. Therefore, such packaging materials or containers have air permeability, or can control respiration, so as to achieve the purpose of preservation.
Nutrition requirements: bag in box manufacturers introduce that food will gradually lose nutrition in the process of packaging and storage. Therefore, food packaging should be conducive to the preservation of food nutrition, and it is more ideal to lock nutrition through packaging. Other requirements: there are many inherent requirements for food packaging, such as heat resistance requirements, lightproof requirements, shatterproof requirements, moisture requirements, etc. http://m.switzerland-hotel.com/
