Life in the fast-paced modern world would be significantly more challenging without the innovations made possible by Chiripal BOPET Films.

Chiripal BOPET Films, also known as BOPET (Biaxially Oriented Polyethylene Terephthalate), is a flexible, clear, transparent, or translucent material derived from polyester (PET) resin. This film is mechanically and scientifically stretched, offering exceptional tensile strength, chemical and dimensional stability, transparency, reflectivity, gas and aroma barrier properties, and electrical insulation.

These attributes make Chiripal BOPET Films indispensable in enhancing convenience and efficiency in everyday applications.

Let’s explore the fascinating world of Chiripal BOPET Films in greater detail.



How Are Chiripal BOPET Films Manufactured?

The production of Chiripal BOPET Films begins with melted PET resin being extruded onto a chill roll, solidifying it into an amorphous state. The film then undergoes biaxial orientation, commonly executed through a sequential process. Initially, it is stretched in the machine direction using heated rollers and subsequently drawn in the transverse direction in a heated oven.

Upon completion of this process, the film undergoes "heat setting" at temperatures exceeding 200 °C (392 °F), ensuring dimensional stability and preventing shrinkage. The molecular alignment achieved through this process is responsible for the high strength and stiffness of Chiripal BOPET Films.

Additionally, biaxially oriented PET film can be metalized by applying a thin layer of evaporated aluminum or other metallic coatings. This enhances its barrier properties, reducing permeability to gases and providing up to 99% light reflectivity, making it ideal for food packaging.

To improve sealability and puncture resistance, metalized Chiripal BOPET Films are laminated with a polyethylene layer.


Diverse Applications of Chiripal BOPET Films

The versatility of Chiripal BOPET Films enables limitless applications across numerous industries. Below are some of its most impactful uses:

Flexible Packaging

  • Extended Shelf Life: Laminates containing metalized BOPET Films prevent oxidation and aroma loss, ensuring food freshness. Common applications include coffee packaging and stand-up pouches for convenience foods, FMCG, and retail products.
  • Candy Wrapping: Silver BOPET has replaced traditional foil in confectionery wrapping.
  • Lidding Applications: White Chiripal BOPET Films are extensively used for yogurt, cup noodles, mineral water, soups, and dessert packaging.
  • Transparent Packaging: Chiripal BOPET Films provide excellent heat resistance, making them suitable for fresh or frozen ready meals and beverages, even during microwave or oven heating.
  • Thermal Lamination: Ultra-clear Chiripal BOPET Films are widely utilized for premium mono cartons and high-end catalogs.
  • Air Balloons: Traditional nylon balloons are now being replaced with metallized and non-metallized Chiripal BOPET Films.
  • Printable Media: These films serve as an essential component in photobooks and security printing.
  • Bag-in-Box Packaging: The wine and beverage industry relies on Chiripal BOPET Films for high-performance flexible packaging.
  • Shrink Sleeves: PET-G variations of Chiripal BOPET Films are highly sought after for uniform shrink sleeve applications.



Why Choose Chiripal BOPET Films?

  • Food-Safe: Many Chiripal BOPET Films are FDA-compliant, ensuring safety for food and beverage applications when used with recommended laminate structures and proper recycling processes.
  • Shock Resistance: The biaxial orientation of polymer chains grants superior strength and rigidity to the film.
  • Excellent Oxygen Barrier: Metalized BOPET Films significantly reduce gas permeability, protecting contents from oxidation.
  • Durability: The PET resin composition enhances the film’s resistance to wear and tear, especially when paired with polyethylene layers.
  • UV Protection: Metalized BOPET Films offer enhanced resistance against harmful UV rays.
  • Optical Excellence: High-gloss surfaces make these films ideal for point-of-sale (POS) and point-of-purchase (POP) displays, as well as lamination purposes.
  • Recyclability: Fully recyclable Chiripal BOPET Films contribute to waste reduction and environmental sustainability.
