Back seal milk powder packaging machine

The back-seal milk powder packaging machine is an automatic packaging equipment specially designed for milk powder (such as infant formula milk powder, adult milk powder, goat milk powder, etc.). Its core feature is the adoption of a back-seal bag type (that is, the sealing edge of the packaging bag is located on the back, forming a flat sealing structure). It completes the integrated process of milk powder metering, bag making, filling, sealing and additional processing, and is widely used in the packaging of small bags (such as 10g, 20g, 50g) or medium bags (such as 200g, 500g) of milk powder in the dairy industry. It is a key equipment for realizing the standardized and portable production of milk powder products. Core Features 1.Adapting to the characteristics of milk powder to ensure product quality Milk powder has the characteristics of being easy to absorb moisture, agglomerate, and being light and easy to generate dust. The equipment is designed specifically for this: Moisture-proof sealing: High-precision heat-sealing technology is adopted to ensure that the back-seal edge is tightly sealed, blocking the entry of air and moisture, and extending the shelf life of milk powder; some models are equipped with nitrogen filling function to further prevent moisture and oxidation. Anti-caking assistance: A stirring device (such as paddle stirring, low-speed stirring) is built in the storage bin to prevent milk powder from agglomerating due to standing and ensure uniform feeding. 2.Advantages of back-seal bag type, adapting to milk powder packaging needs Compared with three-side sealed, four-side sealed and other bag types, the back-seal bag type has the characteristics of flat sealing, upright bag body and complete printing surface: The back seal does not occupy the front printing area, so it can fully display key information such as milk powder brand, formula and nutritional components, improving the aesthetics of packaging; The sealing strength is high and tear-resistant, which is suitable for products like milk powder that need to be opened and closed repeatedly (an easy-tear opening can be made synchronously for the convenience of consumers); The bag type is compact, saving storage and transportation space, and is especially suitable for small-dose portable milk powder (such as travel packs, trial packs). 3.Integrated automatic process to improve production efficiency It integrates functions such as bag making, metering, filling, sealing and cutting, without the need for pre-made bags, and directly completes the whole process through food-grade films: The film is unwound and folded into a back-seal bag type by a forming device, and longitudinal (back-seal) and transverse sealing are completed synchronously; The metering system precisely controls the filling amount of milk powder (the error is usually ≤±1%), adapting to various specifications such as 10g-500g; Some high-end models can synchronously complete additional operations such as date coding, batch number printing, easy-tear opening cutting, and weight detection, realizing "one-click production" with an efficiency of up to 200 bags per minute.
