Aluminum foil insulation bag
Aluminum foil is not poisonous and has no special smell. The inside of the aluminum foil insulation bag is made of pearl cotton, aluminum foil tin foil and other materials. These materials have the characteristics of thermal insulation and are often used in the production of thermal insulation bags on the market. These materials are fully compliant with food safety regulations. The aluminum foil has excellent barrier performance, good moisture resistance and heat preservation. Even if the heat passes through the inner aluminum foil layer and reaches the middle PE airbag layer, heat convection will be formed in the middle layer, and it is not easy to penetrate the outer aluminum foil layer, so as to achieve good heat preservation. Thermal insulation effect.
Portable polyester cooling bag
There are many kinds of cooling bag outer materials, the most commonly used are polyester and PP non-woven fabrics. We use polyester for this cooling bag. Polyester fabric has the following advantages:
1. Good elasticity and strong anti-wrinkle ability.
Polyester fabric has high strength and elastic recovery ability, so the cooling bag made of polyester fabric is more durable, the fabric is not easy to wrinkle during use, has good anti-wrinkle and iron-free performance, and the cooling bag has a better setting effect.
2. Good corrosion resistance
Polyester fabrics are resistant to bleaches, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. Dilute alkali resistance, not afraid of mildew, but hot alkali can make it decompose. It also has strong acid and alkali resistance and UV resistance. Therefore, the cooling bag made of polyester fabric has better corrosion resistance.
3. Strong sunlight resistance
Lightfastness is second only to acrylic. The light fastness of polyester fabric is better than that of acrylic fiber, and its light fastness is better than that of natural fiber fabric. Especially the light fastness behind the glass is very good, almost on par with acrylic.
4. Good color fastness
Although polyester fabric has poor dyeability, it has good color fastness and is not easy to fade. Once dyed successfully, the color will not fade easily. Therefore, the color fixing effect of the polyester cooling bag fabric is particularly good, and it is not easy to fade after long-term use.
5. Good wear resistance
The cooling bag made of polyester material has better wear resistance and scratch resistance, and can be used for a long time without deformation, fading and damage under normal use.
Insulation duration of Aluminum foil insulation bag
The aluminum foil insulation bag can keep warm for 1-3 hours. The main thing is to look at the environment in which the aluminum foil insulation bag is in use and the current weather temperature.
In summer, the temperature during the day is about 30 degrees, so the heat preservation time of the heat preservation bag will be a little longer, about 2~3 hours, but if it is used in winter, it will be shorter, so the heat preservation time The time is different, about 40 minutes to 1.5 hours.
Insulation duration of thickened aluminum foil insulation bag
Thickened aluminum foil insulation bag can keep warm for about 2 to 4 hours. The specific heat preservation time depends on the quality of the aluminum foil insulation bag. If the aluminum foil insulation bag is very thin, the heat preservation time should not exceed 1 hour. If the aluminum foil insulation bag is particularly thick, the heat preservation performance will also be improved, then the heat preservation time can reach at least three to four hours. When we choose an aluminum foil insulation bag, we must choose a slightly thicker one, which can better reduce heat leakage.
