An Insulated Lunch Bag is also known as an insulated bag, an insulation cover, and a heat curtain, and there are two kinds of such bags, detachable and non-detachable Insulated Lunch Bags.
This Insulated Lunch Bag comes with an external layer, one inner layer, and a layer of insulation in the middle, it is adjustable to the actual needs of customers and will be a perfect combination of different materials and a reasonable solution for insulation. Every insulating layer, a result of precise measurement, meticulous design, and careful sewing, is different according to its real user conditions.
It is heat-resistant, stain-resistant, well-insulated and durable, and even can be applied to the insulation of tubes at different temperatures and in various shapes, as well as all kinds of equipment.
This bag is made of bio-fibers, a kind of popular material, which is not extremely high-temperature-tolerant but will not produce any flying chips to hurt our hands. The material used in the layer for insulation, as well as its thickness and size, are decided by actual application conditions, then the insulation can be perfectly assured. The external layer is pieces of coated fabrics, providing properties of acid and alkali resistance, waterproofness, and weather resistance. Based on different temperature requirements, the materials of another two layers are all well-chosen— the layer in the middle is made of suitably insulated cotton and the inner layer consists of appropriate asbestos and stainless-steel wire gauze (function as the wearing layer). The insulated bags are no electric appliances, they are only designed for making the coldness or heat of food last longer, and the food itself is the source of coldness and heat.
Great heat and cold resistance: Insulated Lunch Bags call for a high degree of heat and cold resistance, which means that even in the hot water, they will not be out of shape.
Excellent durability: Insulated Lunch Bags call for a high degree of shock resistance, which means that great pressure and percussion will not cause damages or scratches to the external layer.
Outstanding leakproofness: although different brands of insulated bags may have different ways to make their products leakproof, an outstanding leakproofness has always been an essential element to keep the food fresh.
Better fresh-preservation capacity: the international seal's standards are measured by water vapor permeability tests. The permeability of a quality insulated lunch bag could be 200 times lower than an ordinary one, which means that a well-insulated lunch bag is capable of keeping food fresh.
