Product Description:

Aluminium foil acts as a total barrier to light and oxygen (which cause fats to oxidise or become rancid), odours and flavours, moistness, and germs, it is used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic processing|aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.

Aluminium foil is widely sold into the consumer market, often in rolls of 500 mm (20 in) width and several metres in length.It is used for wrapping food in order to preserve it, for example, when storing leftover food in a refrigerator (where it serves the additional purpose of preventing odour exchange), when taking sandwiches on a journey, or when selling some kinds of take-away or fast food. Tex-Mex restaurants in the United States, for example, typically provide take-away burritos wrapped in aluminium foil.

Aluminium foils thicker than 25 μm (1 mil) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.

Aluminium foil has a shiny side and a matte side. The shiny side is produced when the aluminium is rolled during the final pass. It is difficult to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollers. When the sheets are later separated, the inside surface is dull, and the outside surface is shiny. This difference in the finish has led to the perception that favouring a side has an effect when cooking. While many believe that the different properties keep heat out when wrapped with the shiny finish facing out, and keep heat in with the shiny finish facing inwards, the actual difference is imperceptible without instrumentation.The reflectivity of bright aluminium foil is 88% while dull embossed foil is about 80%.

We provide a full range of precision aluminum strip for almost any application. We produce aluminum strip in a wide variety of alloys, including clad composites. Our aluminum strip can be produced in standard dimensions or custom made to your special requirements. We produce both imperial and metric units. We manufacture in compliance with the main international specifications, and tighter tolerances or custom tempers are available upon request. We offer various surface conditions, custom finishes (painting, anodizing, embossing), special processing, and multiple packaging options to meet our customer's unique requirements. The following is a summary of our capabilities.

Manufactured in compliance with the main international specifications and standards, including:  Aluminum Association, ASTM, EN, and DIN.
We can also manufacture in compliance with other international standards including:ASME, SAE, AMS, AWS, FED, MIL, QQ, ISO, BS, AFNOR, JIS and GOST.

Manufactured in compliance with the main international specifications and standards.
Tighter tolerances are available upon request.

Aluminium alloys with a wide range of properties are used in engineering structures. Alloy systems are classified by a number system (ANSI) or by names indicating their main alloying constituents (DIN and ISO).

The strength and durability of aluminium alloys vary widely, not only as a result of the components of the specific alloy, but also as a result of heat treatments and manufacturing processes. A lack of knowledge of these aspects has from time to time led to improperly designed structures and gained aluminium a bad reputation.

One important structural limitation of aluminium alloys is their fatigue strength. Unlike steels, aluminium alloys have no well-defined fatigue limit, meaning that fatigue failure eventually occurs, under even very small cyclic loadings. This implies that engineers must assess these loads and design for a fixed life rather than an infinite life.

Q:Does the aluminum foil can prevent from the sunlight shining?
Yes, it can prevent the sun shining.
Q:Does some one has ever used the aluminium foil paper to keep the house roof from overheat? How about the effect of this method?
It has some effect, but not durable. The general effect can be better if you use the material like foam glass to keep heat insulation and preservation.
Q:Are aluminum foil container poisonous?
Aluminum foil, with outstanding barrier properties, under the premise of a sufficient thickness of aluminum foil, substantially completely gas and moisture barrier, thus, in plastic flexible packaging materials, aluminum foil is commonly used as barrier material and a lightweight aluminum, and sealed package Overturn good range of benefits. Mainly health, beauty, but also holding on to some extent.
Q:How about the specifications and prices of aluminum foil thermal insulated hose?
Aluminum foil hose is made by winding aluminum foil glass fiber cloth and steel wool on both sides. It has several types including square hose, circular hose, composite hose and thermal-insulated hose. Since it has good fire resistance and flexibility, it can be used in the ventilation o high-rise buildings. Aluminum foil thermal-insulated hose is made by stuffing glass wool between the two layers of aluminum foil on both sides to preserve the internal heat. Coated with aluminum foil Mylar, aluminum foil hose is internally supported by spiral steel wires. By bonding the aluminum foil Mylar on the steel wires and reinforcing the adhesion and tension in the basement layer, aluminum foil hose is characterized by good resilience, fire resistance and safety, thus it is easy for construction. aluminum foil hose is used in dust absorption and air exhaustion such as air exhaustion of public baths.
Q:What is the principle of insulation of aluminum foil tape?
Air-conditioning foil manufacturing air conditioner heat exchanger fin of special materials, the early use of air-conditioning foil is a prime foil. In order to improve the surface properties of plain foil, before forming coated with anti-corrosion coating of organic and inorganic hydrophilic coating to form hydrophilic foil.
Q:Why aluminum foil can be used in food packaging?
2.Aluminum foil barrier is very good, after the metal aluminum is oxidized by oxygen in the metal surface to form a dense layer of oxide Al2O3 protective film to prevent oxygen to oxidation of aluminum metal, of course, made with aluminum foil bags to use this layer a dense protective film can be well isolated from the outside air into the interior of the bag, serve to prevent oxidative deterioration of food is a role.
Q:What is 1235 aluminum foil
Aluminum foil is the thin aluminum sheet which is widely used in the package of drug capsule and the milk seal. The 1235 aluminum foil brand number is the model number.
Q:How to test the withstand voltage of capacitance?
Simple test:the two aluminium lead wire rolled up like the electrician high-voltage shaking unit(produce high voltage)and voltmeter and capacitance connected in parallel like revolving unit to the measurement and read the voltmeter. The voltage should be higher than withstand voltage. take the advantage of capacitance aluminium of restoring and measurement.
Q:Is tin foil paper the same as aluminum foil paper?
The original tin foil paper is indeed made from tin, but as tin foil paper is harder than aluminum foil and easy to affect the food with a taste of tin, aluminum foil paper replaces tin foil paper in daily life after the reduction of aluminum price. However, as aluminum can affect the development of brain, aluminum foil at present is coated to avoid the liberation of aluminum.
Q:What is air conditioning aluminum foil?
Since aluminum has a low density, thermal conductivity, and ease of processing, tasteless, environmental protection and low cost, etc. are widely used, with air-conditioning heat exchangers made of aluminum foil heat transfer fin material is one representative.
