Customized packaging for your need.
There are various packaging forms for milk powder products on the market, among which soft packaging is a more common one. The following is an introduction to milk powder product packaging:
Common milk powder packaging forms
• Canned: usually iron cans or aluminum cans are used, such as some Nestle Nan products. It has excellent sealing performance, can effectively block air, moisture and light, prevent milk powder from getting damp, oxidized and deteriorating, and has a long shelf life. It has strong pressure resistance and is not easily damaged during transportation, but it is relatively heavy and inconvenient to carry, with high production and transportation costs and high prices.
• Boxed: Generally, it is a small independent package in a paper box, such as some products of Friso. This packaging is easy to carry and use, which can ensure the freshness of milk powder to a certain extent. At the same time, the kind of the packaging has a beautiful appearance design. However, the packaging cost is relatively high. The paper box has poor pressure resistance needing to be protected during transportation.
• Combination pack: Some brands have launched a combination of canned and boxed packs, such as HiPP Noka 1897 Hezhi milk powder. It takes into account the sealing and long shelf life of canned and the easy-to-carry characteristics of boxed, meeting the different needs of consumers.
• Flexible packaging: Generally, milk powder is placed in a packaging bag with aluminum plating, which has the functions of oxygen barrier, moisture barrier, light protection, and extremely high sealing. The packaging bags for milk powder can ensure the quality of milk powder on the one hand, and meanwhile they can save a certain amount of cost as well, which is more cost-effective.
Features and advantages of soft packaging for milk powder
• Material and structure: Milk powder soft packaging generally uses composite film materials, and the common structure is printing layer/barrier layer/reinforcement layer/heat sealing layer. The printing layer is mostly PET and BOPP, which can present exquisite printing effects; the barrier layer is mainly aluminum foil or vacuum aluminum plating layer, which can achieve the functions of oxygen barrier, moisture barrier, and light protection; the reinforcement layer can prevent the aluminum foil or aluminum plating layer from breaking or pinholes due to external force; the heat sealing layer is usually made of PE material to ensure that the packaging is well sealed.
• Good barrier performance: It can effectively block oxygen, water vapor and light, prevent milk powder from oxidation, moisture and loss of nutrients. For example, the soft packaging of Nestle Family Nutrition Sweet Milk Powder uses high barrier polyolefin materials, which performs well in water and oxygen barrier.
• Lightweight and low cost: Compared with canned milk powder, soft packaging is light in weight, easy to carry and transport, and the production cost is relatively low, making the product price more competitive and providing consumers with an economical choice.
• Good printing adaptability: Printing layer materials such as PET and BOPP have good printing performance, which can achieve exquisite pattern and text printing, enhance the product's appearance and brand recognition, facilitating consumers to choose from a wide range of products.
Precautions for soft packaging
• Hygiene and safety: As packaging that directly contacts food, it must comply with national standards, and the evaporation residue must not contain harmful heavy metal elements. The total number of bacteria and E. coli must meet the standards, and the solvent residue must be strictly controlled to avoid odor and safety hazards to milk powder.
• Heat sealing performance: The heat-sealing layer must have sufficient hot adhesive strength to ensure a firm seal and prevent leakage during storage and transportation, which affects the quality of milk powder.
• Mechanical adaptability: If used in an automatic packaging machine, the packaging film must have good adaptability to the equipment to ensure smooth operation during the packaging process without slipping, jamming, and other problems.
