Yashili: Three-layer composite film improves bag packaging quality

The packaging of milk powder must take into consideration factors such as prevention of moisture, oxidation, prevention of bacterial growth, and avoidance of UV radiation. To this end, Guangdong Yashili Group Co., Ltd. uses a three-layer laminated film bag with a layer of biaxially stretched polypropylene film sandwiched between a layer of aluminum foil and a layer of polyethylene film, and is sealed with high-frequency electrothermal welding, which basically avoids light, The infiltration of moisture and gas also solves a series of problems of composite plastic film packaging, such as: plastic film insulation, poor light-shielding properties, milk powder is easily degraded, can only meet the needs of short-term storage; brittle and easy to fold, It is easy to cause damage.
