What is Cosmo BOPET Films, and how do Its Applications surround us?

The everyday Lives of Human Beings could be challenging and hectic if no inventions were made for the Cosmo BOPET Films.

Cosmo BOPET Films, also known as the BOPET (Biaxially Oriented Polyethylene Terephthalate), is a clear, flexible, transparent, or translucent material produced from polyester (PET) resin stretched scientifically and mechanically. PET is used for its high tensile strength, chemical and dimensional stability, transparency, reflectivity, gas and aroma barrier properties, and electrical insulation.

Cosmo BOPET Films applications have made our life easy and convenient, and fast-paced for the modern world.

Let’s dive deep and understand more about the Cosmo BOPET Films.

How are Cosmo BOPET Films made?

The manufacturing process of Cosmo BOPET Films starts with the melted PET Resin being extruded onto a chill roll, which quenches it into the amorphous state. It is then biaxially oriented. When This happens, it is called BOPET. The most common way of doing this is the sequential process. The film is first drawn in the machine direction using heated rollers and subsequently removed in the transverse order, for Example – orthogonally to the direction of travel in a heated oven.

Once the drawing is completed, the film is “heat set” or crystallized under tension in the oven at temperatures typically above 200 °C (392 °F). The heat setting step prevents the film from shrinking back to its original 

upstretched shape and locks in the molecular orientation in the film plane. The orientation of the polymer chains is responsible for the high strength and stiffness of biaxially oriented PET film.

Biaxially oriented PET film can be metalized by depositing a thin layer of evaporated aluminum Vapors of gold, silver, or other metal colors onto it.

The Metalized BOPET is less permeable to gasses important in food packaging and reflects up to 99% of light to Protect the Inside Content of applications like food packaging.

The aluminized Cosmo BOPET Films gets laminated with a layer of polyethylene, which provides seal ability and improves puncture resistance.

Applications Gamut of Cosmo BOPET Films

The Applications and conversion possibilities with Cosmo BOPET Films are Limitless, or BOPET applications are abundant around us, to which we get introduced and exposed daily.

We list a few of the Finest Applications of Cosmo BOPET Films for the Sake of Knowledge of all industry Peers.

Flexible packaging and Cosmo BOPET Films

Laminates containing metalized BOPET foil protect food against oxidation and aroma loss, achieving long shelf life. Examples are coffee foil packaging and Stand pouches for convenience foods, FMCG, Food & Retail Industry.

• Candy is being wrapped in silver BOPET.

They were previously wrapped in foil.

• White Cosmo BOPET Films is used for the Lidding Application in Yogurt, Cup Noodles, Mineral water, Soups, and Dessert Packaging.

• Transparent Cosmo BOPET Films is used as lidding for fresh or frozen ready meals & Beverages. Due to its excellent heat resistance, it can remain on the package during microwave or oven heating.

• Ultra Clear Cosmo BOPET Films is Used for the Thermal lamination Process for the Mono Cartons and Expensive catalogs.

• Nylon Air Balloons are being Replaced with the Metallized BOPET and Non-Metalized Cosmo BOPET Films.

• Cosmo BOPET Films also makes Printable Media for Photobook & Security Printing Industry.

• Cosmo BOPET Films is the go-to choice for the Bag in Box Packaging Applications for the Wine Industry & other beverages.

The use of Cosmo BOPET Films is endless; we only need to imagine our Product or Brand Incorporating this into their Product strategy.

PET-G Version of Cosmo BOPET Films is Very Famous for the Uniform Shrink Sleeve Applications.

Why is Cosmo BOPET Films the Right Choice?

Food-Safe

Some of the Cosmo BOPET Films are FDA-compliant, making them safe for packaging and other applications in the FMCG, Food & Beverage industries if the Convertors and Brand use the Recommended Packaging and Laminate structure along with the Proper Recycling Process.

Shock Resistant

The orientation of the polymer chains is responsible for the high strength and stiffness of biaxially oriented PET film.

Excellent Oxygen Barrier

The Metalized BOPET is less permeable to the gas barrier against gasses and oxygen to protect the inside content.

Durability

The PET Resin makes the Cosmo BOPET Films more durable than any other film for wear and tear purposes if combined with the Polyethene layer.

UV Resistant

The Metalized BOPET offers better protection against UV Rays as well.

Optical

High gloss Surface

Cosmo BOPET Films can be developed in the High Gloss Surface category for POS, POP, and Lamination Purposes.

Recyclable

Cosmo BOPET Films is fully recyclable, helping with waste reduction, and does not harm the environment.

Summary

Next time you are working on a project that requires a Packaging film that offers versatility, durability, and resistance to harsh environments, consider Cosmo BOPET Films. Not only for its properties that outshine many of those of the same materials, but it is also a cost-effective solution without betting on the quality.

At Cosmo Film, we look forward to serving you with the best Cosmo BOPET Films.
