Q:How to distinguish between PET gold card paper and foil gold paper peritoneum what is the difference?.

1.PET gold paper and aluminium foil gold paper are different in manufacturing process:PET (polyester) is a transparent plastic, PET gold paper is printed on the substrate (cardboard), affixed with PET film, and then hot stampingAluminum foil is rolled directly into sheet metal with aluminum foil. Gold foil paper is printed or hot pressed on the base material (cardboard) with aluminum foil attached

Q:Can foil be used to shield electromagnetic interference? Please, great God!

There is a certain effect, because it is a metal layer, of course, your package method also has a certain relationship

Q:The aluminium foil is melted and glued to the electric ceramic stove. How can I get rid of it? A safe way of not hurting the stove

Reheated and thawed again.If the area of the foil is slightly larger, you may consider dropping the cold water at the high temperature after heating. But do not control the amount of water dripping. Be careful not to spill the water onto the ceramic panel to damage the panel.

Q:Why aluminum foil used in food packing bags?A, good thermal conductivity, B, good ductility, C and strong corrosion resistance

Oxygen can be prevented from entering the food bag (common plastics can hardly prevent oxygen from infiltrating slowly),

Q:What about the electromagnetic shielding effect of aluminum foil tape and copper foil tape?

Shielding effect is the same, because aluminum is easier to oxidize than copper, difficult to weld and other reasons, the general shielding with copper tape.

Q:What material is the aluminum foil made of?

There are two kinds of roll, divided heat roll and cold roller.The rolls used in common cold rolls include 9Cr, 9Cr2,9Crv, 8CrMoV and so on. The cold rolls require surface quenching and the hardness is HS45~105

Q:What is the specific weight of aluminum foil?

Aluminum foil is a metal aluminum directly rolled into sheets of hot stamping material, the effect of stamping and silver foil stamping similar effects, it is also called the false. Because of its soft texture and good ductility, it has a silvery luster. If the rolled sheet is made of sodium silicate on the offset paper, the foil can be printed. But the aluminum foil itself is easy to oxidize and the color is dull, friction, touch and so on will fade. Therefore, it is not suitable for the long-term preservation of books, covers and other hot stamping.

Q:What are the materials for aluminum foil films? What are the characteristics?

Aluminum foil has all the properties of metallic aluminum. Heat conduction, air tightness, shielding, shielding and electromagnetic radiation are all important properties.

Q:Black shading and shading of the aluminum foil machine what is the difference

A set of yarns or sets of yarns arranged parallel to all the work needles fed into the machine,

Q:Where are the aluminum foil lunch boxes used?
