Why can aluminized bubble bag be insulated?

Aluminized film bubble bag has good toughness, can protect the packaging products from external extrusion. Better protection than regular plastic bubbles, but you know what? Another very unique function of aluminized film bubbles is insulation, let's take a look at the principle.

The material structure of the aluminized film bubble bag is an aluminized layer coated with a CPE bubble layer, and the aluminized layer is a composite material formed by PET electroplating aluminum. It is well known that the main performance of aluminum is to prevent oxygen, light and moisture, so the material of our thermal insulation bag is inseparable from aluminum plating film.

But some friends may ask, why not directly compound aluminum on the bubble, but first coat aluminum on PET? This question is very good, this is because, aluminum has another very special performance, that is, it is fragile, there is no way to be well attached to the bubble, after all, the bubble is not flat and smooth PET film, so only in this way can the advantages of aluminum be better played.

The author also wants to expand the knowledge of thermal insulation bags for friends, the above mentioned thermal insulation bags are inseparable from the aluminized layer, so the thermal insulation bag with an aluminized layer can be insulated, and then the material of the thermal insulation bag can be more diversified, the common thermal insulation bag in our life has aluminized film composite EPE, which is what we often say foam, this foam can have a variety of different thickness choices, When packaging food, different thicknesses can be selected for unnecessary insulation needs.

If we still have printing requirements, there are two different options.

The first kind of surface printing, the other is the inner layer printing. As the name suggests, one is the printing layer is the inner layer, and the other is the surface printing. These two have their own advantages, if we just need to print a small range of LOGO, choose surface printing is better, so that the cost is low and can meet the printing requirements; If we need a large area of full bag printing, then we need to choose the inner layer printing, the principle of inner layer printing is to print the ink on a layer of plastic film, and then this layer of film composite in the outermost layer.

Today to introduce the knowledge is these, if you have other questions or want to know the content, you can give us a message or email to contact me yo.

Have a nice day, everyone~
