characteristic
Thermal insulation: thermal insulation materials, such as pearl wool, aluminum foil tin paper, high-density foam, can effectively block heat transfer, maintain the low or high temperature of milk, and extend the preservation time of milk.
Good sealing: usually equipped with zipper, buckle and other sealing devices to ensure that the inside of the bag is isolated from the outside air, reduce heat exchange, and prevent milk from spilling.
Strong durability: Made of sturdy and durable materials such as nylon, polyester fibers, etc., it has certain wear resistance, tear resistance, and compression resistance, and can withstand friction, collision, and compression in daily use.
Lightweight and portable: Designed to be lightweight and easy to carry, whether placed in a backpack, on a bicycle, or handheld, it will not impose too much burden on users and is convenient for use in travel, shopping, sports, and other scenarios.
Diverse styles: There are multiple options in terms of color, pattern, size, etc. Some are also designed with additional pockets, compartments, handles, shoulder straps, etc., to meet the personalized needs and aesthetic preferences of different users.
purpose
Daily shopping: After purchasing milk, putting the milk carton in a thermos bag can prevent the milk from spoiling due to changes in ambient temperature on the way home, especially in hot summers or cold winters, where the insulation effect is more important.
Outdoor activities such as picnicking, camping, hiking, etc., carrying a milk carton insulated bag can allow people to enjoy fresh and warm milk outdoors, providing convenience for outdoor activities.
Maternal and child care: For breastfeeding mothers, they can use insulated bags to store the extracted breast milk when going out, maintain the temperature of the breast milk, and ensure that the baby can drink safe and healthy breast milk.
Delivery service: Milk delivery personnel use insulated bags during the delivery process to ensure that the milk maintains good quality when delivered to customers, thereby improving customer satisfaction.
Common materials
External material: Generally made of nylon, polyester fiber and other materials, it has waterproof, wear-resistant, UV resistant and other characteristics, which can protect the internal insulation layer and milk carton from the influence of the external environment. For example, Benfan's BF-BAG2 milk insulation bag has an external material of 600D nylon.
Internal materials: Aluminum foil, polyethylene and other materials are usually used, which have good heat reflection and insulation properties, can effectively block heat transfer, and maintain stable temperature inside the bag. For example, some insulation bags use 420D nylon and PPU coating on the inner layer to further enhance the insulation effect.
Material of insulation layer: common materials include pearl wool, high-density foam, aerogel, etc. These materials have low thermal conductivity, which can effectively slow down the heat transmission and extend the heat preservation time of milk. For example, the insulation bag of CH-BOX brand uses three layers of thick aluminum foil cardboard and aluminum foil bag lining, with superior heat preservation effect.
Cleaning and maintenance
Cleaning method: Generally speaking, the milk carton insulation bag can be wiped with a damp cloth to remove surface stains. If the stains are stubborn, a mild cleaning agent can be used for cleaning, but bleach or highly corrosive cleaning agents should be avoided. After cleaning, it should be naturally dried and avoid direct sunlight.
Maintenance points: When not in use, the insulation bag should be folded neatly and stored in a dry and ventilated place to avoid squeezing and scratching with sharp objects. At the same time, the sealing performance and insulation effect of the insulation bag should be regularly checked, and if damaged, it should be replaced in a timely manner.
