Aluminium foils:

Characteristics of Punched Aluminum Foils in Different Sizes:

+ Laminated :

  • Laminated with PE (Poly Ethylene) Film
 This type is using in sealing PE containers; the most common types are used in sealing yogurt containers.
  • Laminated with CPP (Cast Poly Propylene) Film

a) To seal PP containers
This type is used in sealing acidic and alkali materials such as UF cheese, pickles, verjuice and cup buttermilks and so on.

b) To seal PS containers
These types are used instead of PS coated in some cases, in which easily opening is not a matter of importance, (Notice: using PS coating results in having an easy open seal)

+ Coated :

  • Coated with PS (Poly Styrene)
This type is appropriate to do heat sealing the PS containers
  • Coated with PP (Poly Propylene)
This type is appropriate to do heat sealing the PS containers
  • Laminated
  • Coated
  • laminated PE

To use in relating industry....

 

The History of Aluminum Foil:

Unparalleled and unique characteristic of Aluminum foils has been resulted in using it in a wide range of manufactures, including technical application( fire retardant walls and doors, optic fibers and electric cables), thermodynamic transformations ( using as fin in air coolers, heaters, condenser, oil coolers), packaging industries( food products, beverages, pharmaceutical products such as solids, liquids, pomades, jells, creams or tablets, hygienic and cosmetic products, all kinds of oils such as break, machine and industrial ones, all PE of agriculture all pesticides, oil and chemical products, washing materials and detergent), home utilization ( a wide range of utilization from cooking to freezing) and all kinds of products which need packaging and keeping in containers and bottles; To some extent that, now there is a high level of interest toward investment in Aluminum foil industry. Although, this rate is not high in North America, sales of Aluminum foils have faced a noticeable grow in Europe and Asia during first six month, which is a proof of increasing aluminum foil products.

Along with scientific and technological development and increasing our need to Aluminum utilization, different field of Aluminum consuming is recognized and grown; to some extend,available foils in markets are sorted in different groups as follow:

Technical application : fire retardant walls and doors, optic fibers and electric cables
thermodynamic transformations : using as fin in air coolers, heaters, condenser, oil coolers
packaging industries : food products, beverages, pharmaceutical products such as solids, liquids, pomades, jells, creams or tablets, hygienic and cosmetic products, all kinds of oil such as break, machine and industrial ones, all PE of agriculture all pesticides, oil and chemical products, washing materials and detergent
home utilization : a wide range of utilization from cooking to freezing and all kinds of products which need packaging and keeping in containers and bottles; To some extent that, now there is a high level of interest toward investment in Aluminum foil industry

Why Aluminum?

Some reasons why Aluminum is used in a wide range in industry are as follow:

• Economic aspects.
• Long life
• Aluminum foils have a natural hardness in its surface along with it has a transparent layer of oxides in its surface making it stable in several application; Because aluminum oxide prevents of oxidation process.
• Low mass density : Having low density means that; in an equal weight the aluminum capsizes much space in comparison with a high density element or metal.

In addition, there are a large number of other characteristic which are allocated to Aluminum, coming as follow:

• Easy screwing and forming.
• The highest amount of thermic and electric conductivity in the weight unit.
• Corrosion resistance.
• Non toxic
• Easy supply in comparison with other metals
• High reflectivity
• Ideal humid insulator
• Light
• Recyclable
• Earth storage

Especial characteristic of Aluminum metal :

• Aluminum is a silvery white metal with melting point of 658 centigrade and with symbol Al.
• Having 2.7 especial weight and superior characteristics in comparison with other metals.
• Corrosion, oxidation, chemical humid and vapor resistance.
• Capability of easy and soon recyclability .
• Lacking of some characteristic such as magnetic, gleaming, firing and toxic ones.
• Capability of molding, freezing, rolling pin, pasting and riveting, and variation in alloying products .
• Safe characteristics for human and animals and wide range application.
• Surface characteristics; it is produced in different standard condition such as chemical, mechanical and tamper conditions.
