Understanding creative process followed by metalized polyester film manufacturers

It is widely known that metalized films are considered to be a good quality of polymer films which contains a skinny layer of metal, especially aluminum. These films elude a very glossy and shiny metallic appearance and are available at a lower weight and a very reduced price. The metalized polyester film manufacturers produce these metalized films which look exactly like aluminum foil and they are broadly used in the packaging of food and in various another decorative purpose. Some of them are used in special applications like electronics and insulation work.

These lustrous metalized films are also used for laminations and hologram purposes. However, many of them are widely popular in comprising as the twisted wrapper for toffee and candle. They are produced using micro slitting process which ensures a uniform coating of metal on the sheet and maintaining a consistent weight throughout.

Process Being Followed in Developing Metalized Films
The process of using physical vapors for deposition of metals can highly be followed in metallization. Aluminum is considered to be the main metal when it comes to deposition along with other metals like chromium and nickel which can also be deposited. Metals are heated first and then they get dissolved with no air inside. Later, a concentration of the metal gets layered on cold polymer films which gets unwind to the source from where vapors of metal can also be deposited. The coating does not get faded with time.

The metalized polyester film manufacturers use these films which do not let oxygen or any moisture to pass through them. Later, when the bundles made from these foils are subjected to manipulation and repeated handling which is very frequent in the retail environment like consumer handling, cartooning etc., pinholes started to get developed and become permeable.

Numerous Benefits of Metallized Film
Just like aluminum foils, these films have a very shiny appearance and they are not readily get exposed to oxygen, light, and water due to the property of the coating which shrinks the capability of the film. They preserve heat, toughness and low density at lower cost in comparison with aluminum foil. So, these metalized foils hold several benefits over traditional aluminum foil.

Know About Extrusion Coating

Extrusion coating is defined as a process which is used to coat the thermoplastic material onto a substrate like paperboard aluminum foil, woven fabric, paper, PET, BOPP film etc. Most commonly used resins in this process are various polyolefin such as ethylene vinyl acetate copolymers, polyethylene, ionomers, and polypropylene. For instance, extrusion coated film manufacturer use this process is for improving the features of paper by coating it with polyethylene, making it a better water resistant.

Process of Extrusion Coating
It includes coating of a substrate with precisely metered film of molten plastic. The thin extruded molten film is pulled down onto a substrate and then into the nip which is amidst the pressure rolls and chill roll, below the die. A specific amount of pressure is there in between these two rolls which forces the plastic onto the surface. This surface moves at a speed which is faster as compared to the extruded film and the drawing of film onto the desired thickness. This entire process includes- Extruder, Die, Chrome Plated Chilled Roll, Back Up Roll, and Winders / Unwinders.


Advantages of Extrusion Coating
As a process-

• •    Double sided coating to achieve desired properties
• •    Solvent / adhesive free
• •    Thickness of the coating varies depending on the end use
• •    Higher line speeds

As an end product-

• •    Provides moisture barrier
• •    Avoid direct contact of content to the substrate
• •    Provide heat seal-able characteristics
• •    Reduces loss of content

Factors Influencing Coating Performance
