Aluminum foil on paper back is a kind of composite aluminum paper product, which uses the characteristics of aluminum foil, such as moisture resistance, rust prevention, gas resistance, corrosion resistance, etc. Some manufacturers use thermoplastic film as adhesive to combine aluminum foil and paper to form multi-layer composite paper. This composite aluminum foil is a high-performance packaging material, which combines the high barrier performance of aluminum foil with the folding and impact resistance of paper.
There are many kinds of wrapping paper used to keep food fresh or protect food from moisture, such as cellophane wrapping paper, wax paper, parchment and aluminum foil. Although food wrappers can protect the food they wrap, as the only layer of food protection, they may not be the preferred choice. With the development of aluminum continuous rolling technology, composite aluminum foil lining paper products have been produced - combining the quality of wax paper or parchment with the quality of aluminum foil to form a composite packaging product.
Aluminum foil backing paper is mostly used for packaging candy, cigarettes, etc. to protect food from sunlight and avoid food deterioration. Even in hot weather, the waterproof property of this foil is three times that of standard foil. The paper absorbs moisture, while the foil itself protects the contents from other adverse factors. Foil paper with waterproof and oil proof paper on one side is used for packaging butter, cheese, ice cream and other dairy products.
Composite aluminum foil paper is mainly composed of paper base (aluminum foil backing paper), aluminum foil, color coating, etc.
Aluminum foil backing paper: it is a kind of processing paper with high requirements, and the quantitative range is 21~50 g/m2.
Aluminum foil: It is rolled from metal aluminum.

According to different composite processing methods, aluminum foil paper can be divided into vacuum aluminized paper and composite aluminum foil paper.
Composite aluminum foil paper is made of calendered aluminum foil and base paper with a thickness of 0.006~0.008mm, which are processed in a laminating machine through the action of adhesive. Composite aluminum foil paper is a high-grade composite packaging paper that has developed rapidly in recent years. Because of its good moistureproof, mildew proof and fragrance preserving properties, it is widely used in the cigarette industry, with the largest application amount, and is mostly used for the inner packaging of high-end cigarettes.
Aluminum foil backing paper is the base paper of composite aluminum box paper, which is a kind of industrial paper with high requirements. The quantitative range is 21~50g/m2. The quality shall be supplemented and improved according to the actual production of users.
The composite components in the aluminum foil of the paper back material are mostly non-toxic and tasteless materials, which will not pollute the contents and human body, and can easily meet the packaging health and safety standards.
The aluminum foil has the advantages of high separation performance, light weight, long shelf life at room temperature, etc., so that the food is not easily affected by moisture. Ordinary food packaging saves time, waste and loss.
Aluminum foil composite paper has good barrier performance and waterproof performance. For the food coated with light oil, it can prevent the loss of edible oil and has good oil control effect.
The aluminum foil surface can also be printed with different colors of ink as required to improve the effect of packaging and decoration.
The resin can be decomposed when heated to high temperature, separating paper and aluminum foil, thus greatly improving the recyclability of materials, reducing the waste of materials and the load on the environment.

Chalco aluminum foil backing paper for decoration materials
Aluminum foil backing paper is also used in the field of decoration materials. It not only forms a waterproof film between gypsum and decorative finish, but also increases insulation and helps prevent condensation. You can use it under wallpaper or lining paper. It even helps prevent mold from growing on the walls.
It is a kind of asphalt foil, which can prevent moisture and related problems, such as mildew and mildew. It is 3 layers (kraft paper, asphalt and foil). Of course, if moisture seeps in from outside, the problem needs to be solved. For example, if you have a leak, you still need to fix it. However, this kind of foil does come in handy in some projects. Some people use it in the bathroom to reduce condensation.
Chalco aluminum foil backing paper for energy-saving lamps
Since the second half of 2003, the packaging box of energy-saving lamps of Philips Yaming Lighting Co., Ltd. has been packaged with laser aluminum spray paper. The original packaging box of Philips Energy Saving Lamp was made of paper composite anti-counterfeiting film. Because of the plastic film in this material, it is not environmentally friendly. In order to maintain the good image of international enterprises and effectively reflect the coordinated development of economy, society and environment, Philips decided to use environment-friendly aluminum sprayed paper on the new packaging box of the Energy Saving Lamp.
The new packing box is finished with (250-300) g heavy laser aluminum spray brush. The display effect of the packaging box shelf made of aluminum sprayed paper is very outstanding, which is more glossy and layered than the original packaging. And the stiffness, compressive strength and seismic performance of the new packaging box are still very ideal after transportation, storage and handling.
