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%.

Q:How to make aluminum foil paper?
A method to manufacture aluminum foil paper with forgery-proof watermark is made from paper pulp fiber. The production steps are as follows: Crash the pulp material with hydrapulper and beat with beater with beating degree of 20-70°SR and wet weight ≥0.5g; Add additives to the pulp: Filler 10-40%, sizing agent 1-8%, preservative 350ml/ton; Beating degree of 20-70°SR and wet weight ≥0.5g; Press the watermark net with die sinking, use watermark net at the vat of paper machine, reproduce the pulp into paper sheet with paper machine after being diluted, roll the sheet with calendar, slit the sheet into corresponding specification with slitter and then get the aluminum foil backing paper with forgery-proof watermark. The watermark of this invention is distributed uniformly, clearly visible as well as obviously rough and uneven in surface by touching, which has significant counterfeit effect, so it can be used to package the cigarette. Sovereignty item 1: A method to manufacture aluminum foil paper with forgery-proof watermark is made from paper pulp fiber. The production steps are as follows: a. Beating: Crash the pulp material with hydrapulper and beat with beater with beating degree of 20-70°SR and wet weight ≥0.5g; b. Composite pulp tank: Add additives to the pulp: Filler 10-40%, sizing agent 1-8%, preservative 350ml/ton; beating degree of 20-70°SR and wet weight ≥0.5g; c. Press the watermark net with die sinking, use watermark net at the vat of paper machine; d. Reproduce the pulp into paper sheet with paper machine after being diluted, roll the sheet with calendar, slit the sheet into corresponding specification with slitter and then get the aluminum foil backing paper with forgery-proof watermark; e. Composite aluminum foil with watermark aluminum foil backing paper to make aluminum foil paper with forgery-proof watermark.
Q:What is the material of aluminum foil film and what are its characteristics?
Heat conduction, air tightness, shielding, shielding and electromagnetic radiation are all important properties.
Q:Is the environmental friendly aluminium foil box poisonous

Q:What are the differences between aluminized film and aluminum foil film?
Aluminized film is a film, such as PP, PET and other vacuum evaporated aluminum layer; aluminum foil film is a composite of aluminum foil and plastic film. Aluminum coating is very thin, the thickness is 300-400, and the aluminum foil is about 0.01mm.
Q:Does working in the aluminum foil companies harm the health?
I am working in the same company with her and I am a maintenance worker in aluminum foil workshop.To be honest, it is the cleanest workshop in the whole factory. Only little kerosene can be smelt. What's more, her main job is foreigh trade, nearly outside the workshop.
Q:Aluminum foil composite film which good quality?
Has the advantages of high strength aluminum woven composite film, good sealing performance, moisture resistance, shading, tear resistance, puncture resistance and other advantages, is widely used in various large precision vacuum packaging equipment, various equipment shipping, transportation and long-term storage of choice of flexible packaging materials.
Q:five facts about aluminium?
Take a look on this website - They have some interesting information about aluminium - www.bwcaluminium.co.uk
Q:Would it be a bad thing to build an aluminum motorcycle frame?
First in 1973 Harley did not make a rigid frame, so please double check your year. Aluminum is a bad idea, it won't hold up. We recommend Steel .125 wall, DOM (seamless) Or if you have Ex. welding skills, Chrome Moly tubing is much lighter and stronger.
Q:Did you know aluminum in deodorant cause breast cancer?
This is only a theory, but I avoided the aluminum based ANTI-PERSPERANTS anyway. The deoderants usually don't have aluminum, so I bought the products that just said deoderant. I used to use a woman's product without aluminum, now I cannot find women's products that only have deoderant. Some other men's products that DO NOT have anti-persperants/aluminum, are Speed Stick by Mennan,(various scents). Interesting that there is a theory that aluminum in ant-ipersperants, may cause breast cancer, and all of the women's deoderants now have aluminum in them. Wonder why that happened? Some company could make a fortune if they started manufacturing women's deoderants without the anti-persperant containing aluminum.
Q:What are the key features and advantages of the aluminum foil food bags?
2, oil resistance and good aroma and particularly outstanding performance 3, excellent barrier properties, barrier properties and strong air, anti-oxidation, waterproof, moisture-proof 4, good sealing performance, high softness
