What is a Polyester Film?
The film is made from polyester, a kind of polymer resin. Polyester is a highly adaptable plastic film that possesses excellent optical, physical, mechanical, thermal, and chemical characteristics. Sometimes referred to as "Biaxially Oriented Polyethylene Terathalate," or simply "Polyester," Polyethylene terephthalate is the chemical name, and its common acronym is "PET."
Biaxially orientated PET, or BOPET, is the most widely used polyester film.1 It maintains its physical qualities across a wider temperature range than most other popular plastic films, from minus 70 degrees Celsius to plus 100 degrees Celsius.
The polyester film comes in a wide range of styles, widths, and thicknesses with qualities designed to satisfy the needs of a wide variety of applications.
What are the Uses & Benefits of the Polyester Film?
1. Directly Printed Electronics
To guarantee good registration and performance of silver conductive inks, MelinexAR ST polyester films are thermally stabilized at 150A C for 30 minutes (MD/TD shrinkage at 1%).
2. Optical Displays
MelinexAR 453 is a high-clarity film that has been coated on one side to improve its adherence to most printing inks and industrial coatings. If you need a material with a double coating, choose MelinexAR 454.
3. Flexible Electronics
In Flexible Electronics applications like membrane switch circuits, MelinexAR ST polyester films may be used as both the printing shorting pad layer and the bottom circuit.
4. Medical Films
Diagnostic test strips, transdermal patch components, medical face shields, microfluidic tests, and medical labeling are just a few examples of when the medical film is put to use.
5. Cast and Release
You may "release" anything from a package by mechanically adding fillers to the basic polymer, or you can use a chemical coating (like silicone) to the product film (the most popular of which is called MylarAR RSXR951).
6. Tags & Labels
The print-receptive bases of several MelinexAR and MylarAR materials make them ideal for use with pressure-sensitive labels.
7. Electrical Parts
High dielectric strength, thermal durability, and thermal and electric barrier resistance are features of MylarAR, MelinexAR polyester, and TeonexAR PEN films.
8. Postal Application Forms
Films that have been modified to work with various printing processes, such as screen printing, offset printing, and lithography. Polyester can have additional coatings applied to make it suitable for digital printing.
9. Industrial Use
MylarAR A is a polyester film that may be used for a wide variety of purposes, from industrial to everyday ones like stencils.
1. The Advantages Grow While the Prices Fall:
Biaxially oriented polyester film provides several advantages over competing materials, but they are also less expensive.
These films are one of the most efficient ways to cut money while still getting the job done. Polyester films are inherently resistant to UV light and do not require de-lamination, unlike other polymers. When it comes to transporting and storing goods, they are the most effective at preventing damage from environmental factors and natural disasters.
2. Stylish and Comfortable
Polyester films are highly useful, and they also happen to be aesthetically pleasing. With their superior shine and great transparency, they make for a visually appealing final touch on product packaging. Additionally, silk and matte, films are available in a wide variety of additional sheens, textures, and tonalities.
Best of all, they don't become wrinkled or shrink in unfavorable climates or lengthy shipping times.
3. It's Like Finding a Treasure Chest of Options
Polyester films are versatile because their physical properties may be easily modified during manufacture to meet specific packaging or product needs. This can be achieved by incorporating chemicals into the polymerization of the PET resin, such as slip modifiers (surface modifiers) or color additives. Surfaces can be treated externally to achieve a variety of finishes.
4. It's Practical Yet Eco-friendly
Polyester films are becoming increasingly common because they meet the criteria for being environmentally friendly. That shopping today knows full well that protecting the environment is crucial.
For this reason, they are increasingly picking out products with eco-friendly attributes. Polyester films, as opposed to regular plastic, are the best option in this situation.
How Many Types of Polyester Film?
1. APET Film
To be more precise, APET Film is an amorphous polyethylene terephthalate thermal pet film. Rigid pet film, rigid polyester film, and APET Sheet are all other names for APET film. Its high clarity and low processing cost are making it a go-to for a wide range of packaging applications. In addition, polyester is replacing other plastics like PVC film since it is an eco-friendlier option.
2. Transparent Polyester film roll
PET Film is another name for polyester film. This product is fabricated using PET that has been stretched (PET). It is transparent, has excellent scent barrier capabilities, is electrically insulating, and has high tensile strength, among other advantages.
Available in the standard thicknesses of 6 mics, 12 mics, 23 mics, 25 mics, 50 mics, 75 mics, 100 mics, 250 mics, and 350 mics, transparent polyester film rolls are a convenient option for many applications.
3. White PET film
Titanium dioxide is added to a particular PET masterbatch to create a white opaque polyester film. This low-transparency PET film has a high opacity, making it ideal for use in a wide range of industrial and packaging contexts. It's got great mechanical strength, can withstand high temperatures, and holds its shape well. When it comes to printing, nothing beats the versatility of the opaque white polyester film.
4. Yellow Polyester Film
PET Film or Polyester in a Sunny Yellow Color masterbatch is used to create the various hues used in the film. This is a film made using a chip-dyed boat. It has the potential to serve as a superior surface for commercial and industrial purposes. Consequently, insulating tapes and release film liners are where it finds their primary use. The most common thicknesses for the yellow film are 25 microns, 50 microns, 75 microns, 100 microns, and 125 microns.
5. PET Protective Film
The PET material used in protective films is clear and colorless. This surface has been treated to make it harder. There is a 3H-4H range for surface hardness. Wear resistance increases with increased surface hardness. PET protective film materials' principal virtue is also their transparency to light. In most cases, more than 90% of light is allowed through.
6. Heat Sealable PET Film
One type of coextruded, biaxially oriented polyester film is heat sealable PET film. Corona treatment on one side of the film makes it suitable for heat sealing. A different treated or untreated corona side. Good ink adherence has been achieved by corona treatment on the side that will be used for printing.
7. PET Release Film
In the field of thermal transfer, PET release film is frequently employed. It uses PET film as its foundation. As a result of its silicone coating, it is also known as Silicone coated release film or Silicone PET Release Film.
8. PETG Heat Shrink Film
GPET (Glycol-modified Polyethylene Terephthalate) film, also known as PETG HEAT Shrink Film, is another name for this material. This plastic film is an amorphous polyester, meaning it lacks a crystalline structure. Polymerization through condensate yields TPA, EG, and CHDM as its constituents. When it comes to heat resistance and shrinking, nothing beats PETG Heat Shrink Film.
Between 70 and 80 degrees Celsius, it begins to shrink. Up to 80% reduction is possible.
9. Black Polyester Film
A unique black color masterbatch is used to create the black polyester film. (BOPET film with a dyed chip) It has excellent heat stability, mechanical properties, and black coverage. Insulation, application, light-shielding, and shading tape are all common uses. Recommended thicknesses are 50 u, 75 u, 100 u, 125 u, 150 u, 175 u, 188 u, 250 u, and 300 u.
Things to Consider Before Selecting a Polyester Film
How high-end is the app? Medical packaging is high-end, whereas flexible duct polyester film is low-end.
Buying wider might increase costs. Different manufacturers' widths need trimming (deckle). The more a manufacturing line is trimmed, the higher its efficiency and yield, and the savings may be passed on. This charting helps increase manufacturing profits.
3. Inner Diameter
Larger cores provide for greater economies of scale. Smaller core sizes, such as 1 and 3 in., can't hold production-friendly weights and roll lengths. 10-in. cores carrying jumbo rolls are gaining popularity due to fewer post-production changeovers.
4. Outer Diameter
The wider a roll's O.D., the longer its length and the better its efficiency, which means more output and less changeover time. Today, 26-30 in. O.D.s are optimal.
Haze and clarity affect film prices. A clearer, brighter film costs more. Film processing increases these costs. The "filler-free" chemistry of brighter films requires slower processing, more cautious handling, and poorer manufacturing yields.
Handling might affect a film's profitability. Internal (fillers) and exterior (topical, therapy), surface alterations, and coextrusions can influence COF.
Most polyester film is 90 to 110 percent MD and TD. When tensile strength is modified, production rates and forward draw manufacturing units that create a sensitized film for the magnetic and thermal transfer ribbon industries are slower and more expensive.
