Aluminum Foil Is The Most Commonly Used Material In Modern Packaging
Oct 30, 2017

Aluminum foil is not only soft texture, good ductility, easy to process, and light and beautiful, easy to recycle, environmentally friendly, is the most commonly used in modern packaging materials. However, because aluminum foil easily in the packaging, the use of the formation of pinhole and reduce its barrier performance, so aluminum foil often with the film, polymer or other metal sheet made of composite materials used. The practice has proved that aluminum foil composite can greatly improve the barrier of packaging, Aluminum Foil improve the mechanical strength and mechanical properties of aluminum foil, especially for the production of composite flexible packaging vacuum aluminum foil bags and packaging lining, widely used in food, medicine, cosmetics and other goods packaging.

The use of aluminum foil moisture, rust, gas and corrosion resistance, so that the paper with the post to become aluminum foil composite paper, or thermoplastic plastic film as a adhesive to the aluminum foil and paper composite into multi-layer composite paper. Aluminum Foil This composite paper synthesizes the high barrier of aluminum foil and the folding resistance and impact resistance of the paper, and becomes a high-performance packaging material. Most of the compounds in the material are non-toxic and tasteless materials, will not cause internal and human pollution, easy to achieve the packaging of health and safety standards, Aluminum Foil and because of the resin in heating to the high temperature can be decomposed, so that paper and aluminum foil separation, thus greatly improving the recycling of materials, reducing material waste and the environment caused by the load.

At present, this kind of processing paper variety, can be used according to different needs of different paper. In the industrial product packaging used kraft paper more, and plastic can be used polyethylene, polypropylene, polyester film, etc., especially the use of polyester film made of aluminum-plastic composite papers, folding aluminum foil is not easy to break, not easy to form pinhole, Aluminum Foil you can maintain its excellent barrier performance. In order to improve the strength of composite processing paper, it can also be sandwiched into the reinforcement network to meet the need for heavy duty packaging. Because of the high barrier of aluminum-plastic composite processing paper and a variety of packaging adaptability, so now whether in the industrial product packaging or food packaging has a wide range of applications.

Aluminum-plastic composite tank is made of aluminum foil and plastic film, kraft paper (cardboard) composite, can be made into square, cylindrical, rectangular, Aluminum Foil cone and other forms of packaging cans. Among them, cylindrical aluminum foil composite cans (hereinafter referred to as LFG cans) first appeared in the United States, now many countries are used in this form of packaging.

The LFG tank is characterized by low quality, 20% lighter than aluminum cans, and a 20% lower than the cost of a horse's iron pot. Of course, it's cheaper than aluminum cans. The liquid, solid content has good moisture resistance, sealing, shading and barrier, especially to avoid the common horse iron cans weld place pollution; stiffness, mechanical strength, compressive strength, Axial pressure and end-cover force are high, Aluminum Foil especially suitable for the packaging of frozen food.

This kind of tank is generally exceptionally surface, cardboard, inner liner and inner surface layer 4 parts. The appearance layer is the label layer, uses in the printing trademark and so on the text, Aluminum Foil can use the paper, plastic film or aluminum foil composite material; The cardboard layer is made of $number layer long fiber paperboard to ensure the stiffness and mechanical strength of the tank body. Aluminum Foil The inner lining is the main part of the tank body, as the barrier layer, which plays the role of moisture-proof, seepage-proof, and light-resistance, so the composite material Commonly used are coated aluminum foil, aluminum-plastic composite materials or aluminum-plastic paper composite materials. At the same time, because of its good processing performance, can also be based on different packaging requirements, flexible transformation of composite layer and structure.

This composite material also has non-toxic, tasteless, do not pollute the characteristics of the inside, can be reused, recycled, used to replace tinplate and other metal sheet can avoid the metal weld caused by pollution, but also to further reduce costs and improve economic efficiency.

Aluminum foil with clean, hygienic and shiny appearance, it can be made with many other packaging materials integrated packaging materials, and aluminum foil surface printing effect than other materials are better, in addition to aluminum foil has the following characteristics:

(1) aluminum foil surface is extremely clean, hygienic, Aluminum Foil any bacteria or microorganisms can not grow on its surface.

(2) aluminum foil is a non-toxic packaging material, it can be directly contact with food without any harm to the health of human suffering.

(3) aluminum foil for a tasteless odorless packaging material, Aluminum Foil will not make the packaged food has any peculiar smell.

(4) If the foil itself is not volatile, it and packaged food will never dry or shrink.

(5) No matter at high temperature or at low temperature, aluminum foil will not have oil infiltration phenomenon.

(6) Aluminum foil is a kind of opaque packaging materials, Aluminum Foil so for the Sunshine line irradiation products, such as margarine is a good packaging material.
