The dairy industry holds the "national tide style", choosing the right packaging is equivalent to half of it

　　Data show that at present, after 1990, they have become the main consumer. They are pursuing fashion and novelty and chasing trends. Therefore, if modern products want to come out, they must grasp the characteristics of 1990, continue to innovate research and development, and combine corporate brands with young trends in the trend of young trends in Let's tell the brand story together.

　　At present, Guo Chao and Guofeng, as a new form of expression and attitude, have attracted much attention from consumers. Many dairy companies introduce national tide elements and launch people with refreshing online celebrities and brand joint products. For example, Sanyuan pure milk joins hands with the Forbidden City culture, Guangming fresh milk is integrated into the big white rabbit milk sugar, Yili raw milk ice cream meets Hankou Second Factory soda, etc. The combination of these classics and trends refreshes consumers' understanding of domestic goods, and also allows consumers to make consumers Feel the new vitality of dairy products.

　　The combination of dairy products and national tide style, the most important and most impact is the packaging bag, the appearance design of the packaging bag, and the material selection of the packaging bag, which will affect the overall performance of the product. The appearance design is unreasonable and cannot express the trendy elements. If the material selection is incorrect, it will affect the quality of fresh milk. Therefore, choosing the right packaging is equivalent to half of success.

　　Dairy products are fresh drinks, which have strict requirements on sanitation, bacteria, and temperature, and also have high requirements for packaging containers. In summary, the packaging and printing film should have smoothness, thermal sealing, stretching, and lubricating tension on the surface. It must be able to prevent pollution, keep safety, and avoid microbial infection. At the same time, in order to ensure the freshness of milk, it must also be high -resistance, high shieldability, and water separation to ensure that the milk nutritional content and tissue status are relatively stable during the transportation and storage process to ensure the quality of milk.

　　In order to meet the above requirements, the current dairy product packaging is generally selected for polyethylene co -squeezing membranes. According to the composite of the film, it is divided into single -layer packaging film, three -layer composite packaging membrane and five -layer composite packaging membrane.

　　I. Single -layer packaging film is generally made of a certain percentage of white parent materials from various polyethylene materials. It is produced by the film blowing device. The Pakatanide sterilization method (85 ° C/30min) is used for heat installation. This packaging film is relatively thin, the price is relatively low, the toughness is average, and the shading effect is not available. The shelf life of the dairy product of the packaging is generally about three days.

　　Two or three layers of black and white composite film. This membrane is the most common packaging method. Generally, LDPE, LLDPE, EVOH, MLLDPE and other resin are generally adopted, and high -performance composite membranes made of black and white mother materials are squeezed by black and white mother materials. Among them, the black mother material has shielding, so the shelf life of this packaging dairy product is longer, and it can reach about 30 days at normal temperature.

　　Three or five layers of black and white composite film. This packaging is a sterile package. In addition to the three layers of composite membrane materials, the five -layer composite membrane blows the intermediate barrier (composed of high -resistance resin such as EVA and EVAL). This kind of packaging has excellent blockage, thermal sealing performance and oxygen resistance are equally good. Therefore, the shelf life is longer, and it can be stored for 90 days at normal temperature.
