Occasionally, a thermal bag's ice retention period will be listed in the product description. How long the ice can be stored in the bag before it begins to melt. While these measures can serve as a general guide, it's important to keep in mind that ice may melt more quickly than the estimated time if you're using it outside or if the temperature is higher than normal.
(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.
(2) Durable
To have superior impact resistance, it is not easy to break and leave scratches when pressed or impacted.
(3) Sealing
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.
(4) Preservation
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.
For food delivery businesses, insulated lunch bags are perfect. They keep food fresh during transit. Custom-branded bags improve the customer experience and keep meals hot.
(1) The food left inside the lunch bag is easy to produce bad smell, so the lunch bag must be cleaned regularly.
(2) Open the upper cover and clean and wipe it with a soft towel or sponge dipped in warm water or neutral detergent.
(3) After using detergent, it must be cleaned with clean water and then wiped dry with a dry cloth.
(4) Always remove the dust from the top of the lunch bag to avoid affecting the aesthetic effect.
(1) When cleaning the lunch bag, do not directly sprinkle water on the box or the box body, so as to avoid man-made damage to the bag and infiltration into the insulation layer.
(2) Open flame contact or sharp tool cutting is prohibited.
(3) Avoid long-term exposure to rain, humidity and sunlight, which will affect the thermal insulation effect.
