Carrying Bento is a healthy and natural way of life. Lunch bags are recognized by school and office workers for their concepts of safety and environmental protection, cold and heat preservation, convenient carrying, sanitation and easy cleaning. With the development of living standards, it has become a common phenomenon to bring meals out or for office workers. Enjoy all kinds of delicious food at home and with your family. You can also take it out of the lunch bag and enjoy it outdoors or at your place of work.
Although the appearance of the lunch bag is no different from that of an ordinary handbag, there is a large gap in the internal structure and functional nature. From the functional nature, the lunch bag is just like a mobile "refrigerator". Lunch bags are usually made of Oxford waterproof fabric, as well as felt or rubber materials. Oxford lunch bag is lined with pearl PE cotton insulation layer, strong and stylish. Easy to use, carry and clean.
(1) Heat and cold insulation
Heat preservation is the most basic function of lunch bag. It is a special bag with short-term heat preservation effect. The product insulation layer is pearl cotton + aluminum foil tin paper, which can provide good heat insulation effect. According to the needs of life, different sizes are designed and equipped with reusable technological ice bags, which can keep cold.
To have superior impact resistance, it is not easy to break and leave scratches when pressed or impacted.
This is the first consideration when choosing a lunch bag. Although different brands of products have different sealing methods, excellent sealing is a necessary condition for the lasting preservation of stored food.
The international sealing measurement standard is evaluated by the moisture permeability test. The moisture permeability of high-quality felt lunch bags is 200 times lower than that of similar products, which can keep the food fresh for a longer time.
3. Maintenance instructions for the lunch bags
(1) The food left inside the lunch bag is easy to produce bad smell, so the lunch bag must be cleaned regularly.
