X-ray inspection equipment can reach the penetration of 30-34mm thick steel plate, and the wire resolution is 40AWG, that is, the wire with a diameter of 0.08 mm
Therefore, tin foil packaging can't shield X-rays, and the structure of the packaging will be very clear. In addition, metal wires with a diameter of 0.08mm can be distinguished, and their penetrability is also different, including 14mm steel plate, 38mm steel plate, 40mm steel plate and 43mm steel plate, among which the steel plate with a penetrability of 40mm is the most common.
Use of aluminum foil paper:
Aluminum foil paper refers to the paper made of aluminum foil backing paper and aluminum foil pasting and bonding. Soft and easy to deform, like paper, it does not rebound after deformation. Can be qualitative, ensure shading, will not fall, opaque, pollution-free, and cheap. Used for moisture-proof and decorative packaging of high-grade cigarettes, sweets and other foods.
It is also used as raw and auxiliary materials for industrial manufacturing, and the packaging aluminum foil only accounts for 30% of the total domestic demand. Although the development of aluminum foil packaging is late, the market is growing rapidly and the prospect is eye-catching.
This is very significant in architectural applications. Sticking to the surface of thermal insulation material makes the construction more convenient and clean, especially the aesthetics has reached a new height. However, the effect of different kinds of aluminum foil paper is very different, for example, fireproof and ordinary are not of the same grade.
