Brief introduction of cooler bag

There is thermal cooler material in the thermal cooler bag. This material has a relatively low thermal conductivity, which hinders the contact with the air, so that the temperature in the bag can not be directly dissipated. The thermal cooler bag is made of Oxford cloth or nylon cloth, which is tough and wear-resistant. There are waterproof rubber soles and anti-skid pads, independent thermal food storage, equipped with anti-pressure system, not to be squeezed. cooler bag, also known as passive refrigerator, is a kind of bag with high heat preservation and constant temperature effect, which has the functions of cold preservation, warmth preservation and freshness preservation. Aspects to reduce heat loss. The thermal cooler bag adopts special materials, especially the inner material, the density is higher than the density, and the super-dense thermal cooler cotton is often added in the middle. The thermal cooler lunch box is developed from the thermal cooler bottle. The thermal cooler principle is the same as that of the thermal cooler bottle. Reflecting thermal radiation, the cup's vacuum layer or cooler can block heat transfer. The thermal cooler bag is a bag with a constant temperature effect, which can prevent cold/warm in winter and cool in summer. The thermal cooler layer is super thick thermal cooler cotton, which has good thermal cooler effect, foldable and easy to carry.

The following is a list of contents

• The reflective fabric inside the thermal bag is reflective tin foil

• It saves a lot of plastic bags and supports environmental protection

The reflective fabric inside the thermal bag is reflective tin foil

The reflective fabric inside the thermal bag is reflective tin foil. Tinfoil, also known as aluminum foil, is a tool made of flat metal aluminum, which is mainly used for kitchen cooking, serving food, or making some simple and clean materials. Thousands of tons of aluminium foil are used globally to protect and package food, cosmetics and chemicals. Most foils are glossy on one side and matte on the other. Food can be covered with aluminum foil on both sides of the food. Generally, it is recommended to cover the front of the food to improve the thermal conductivity. The thermal cooler effect of 2-3 hours and 6 hours is different, mainly because of the different internal thermal cooler materials, the thermal cooler effect of the inner aluminum foil will be better, and the effect of the pearl cotton aluminum film will be worse. If you want to increase the thermal cooler effect, you can also add an ice pack. It is usually better to use pearl cotton to maintain the temperature

It saves a lot of plastic bags and supports environmental protection

It saves a lot of plastic bags and supports environmental protection; it is clean and hygienic, the cooler bag itself is waterproof and oil-proof, and the materials are all made of environmentally friendly materials, which have excellent wear resistance and wrinkle resistance; the heat preservation effect is good, and the food is still steaming when you go out. . In this way, the problem of working and eating for office workers can be easily solved, and the opportunity to go out for a picnic can be greatly increased; the thermal cooler bag itself is low in price, and can be used multiple times. Print personalized slogans to enhance visibility.

There are large and medium-sized thermal cooler bags designed for motorcycles, bicycles, and automobiles. There are also sports backpacks, school bags, professional gift and product packaging bags, and leisure shopping bags. The thermal cooler bag is designed to be more Professional development, more and more can bring the most affordable services to people's lives. At present, the thermal cooler bags on the market can be kept warm for about 4-6 hours. It is recommended to add ice cubes or more items inside.
