cooler bag: The secret of the summer crisper

As time goes by, summer is coming. In the hot summer, whether it is a seaside holiday, outdoor picnic, or the delivery of raw ingredients, ice packs can play an important role in bringing a lot of convenience to people's lives. What exactly is an cooler bag? What scientific and technological secrets does it contain? Now, let's go into the world of ice packs.

Core material, casting excellent performance

The key reason why the cooler bag can achieve efficient insulation is the special material used. At present, the outside of the mainstream cooler bag on the market uses Oxford cloth, nylon cloth, non-woven fabrics and other fabrics. Oxford cloth thin, wear resistance, good water resistance, and has good wrinkle resistance, can withstand a variety of outdoor environment test. Nylon cloth is known for its high strength, high toughness, not only waterproof, but also has excellent tear resistance, extending the service life of the cooler bag.

The insulation layer inside the cooler bag is usually made of materials such as pearl cotton, EPE foam or aluminum foil. Pearl cotton has good thermal insulation performance, light texture, significant buffer effect, can effectively block heat transfer, protect the items in the ice pack from external high temperature. EPE foam insulation performance is excellent, high chemical stability, not easy to deformation, friendly to the environment. Aluminum foil has reflective properties, can reflect the outside heat, further enhance the insulation effect, to ensure that the ice pack inside to maintain a low temperature state.

Innovative design, showing humanized care

Today's cooler bag pay more attention to humanization in design, and have been carefully optimized from appearance to function. In the appearance design, the ice bag is rich in color, diverse patterns, and integrates fashion elements. It is not only a practical fresh-keeping tool, but also a fashion item. Some cooler bag also adopt a collapsible design, which can be easily stored when not in use, saving space and convenient to carry, greatly facilitating people's travel.

In terms of functional design, the cooler bag is equipped with multiple pockets to facilitate users to classify and store items. Some cooler bag have a dry and wet separation area, which can store wet items separately from dry items to keep them dry and clean. In addition, some of the cooler bag are also installed with air vents to effectively avoid the accumulation of internal water vapor and prevent moisture.
