PET and Polyester Films

Electronics: Used for insulation tapes, insulating spacers in electronic components, flexible circuits, and displays. It's also used in camera shutters and other electronic product components due to its resistance to temperature, chemicals, and wear.

Adhesive Tapes: Employed as a backing material for various adhesive tapes, including insulation tapes and light-blocking tapes.

Packaging: Used in flexible packaging for food, beverages, and pharmaceuticals, thanks to its barrier properties and food safety. It is also used for labels and tags.

Solar Energy: Used as a protective layer in photovoltaic cells and solar backplanes.

Decoration and Lamination: Can be used in furniture surfaces, building components, and for decorative and protective laminates.

Musical Instruments: Utilized for drumheads in musical instruments.

Other Industrial Applications: Includes uses in membrane switches, sound film diaphragms, shading screens, and as a base material in various industrial processes. 

Golden polyester film, often referred to as gold metalized polyester film, is a specialized type of biaxially oriented polyester film (BOPET) with a luxurious golden appearance. This golden effect is achieved through a vacuum metallization process that applies a thin layer of golden-colored metal to the film. 

Here's a breakdown of its key features and uses:

Features

Vibrant Golden Appearance: The most distinguishing feature, providing a rich and metallic gold finish.

Superior Gloss: Offers a higher gloss compared to lacquer-coated metalized films.

Excellent Barrier Properties: Provides a strong barrier against moisture, oxygen, light, and aroma loss, enhancing the shelf life of packaged products.

High Tensile Strength: Ensures durability and resistance to pressure.

Good Thermal Properties: Can withstand a range of temperatures, including high temperatures for sterilization and refrigerated/frozen conditions.

Good Printability: Can be printed using various techniques.

Dimensional Stability: Maintains its shape and size over a wide range of temperatures.

Food Contact Safe: Conforms to food safety regulations like EC 10/2011, REACH, and US FDA standards, ensuring it doesn't contaminate food or beverages. 

Uses

Flexible & Carton Packaging: Enhances the visual appeal and barrier properties of packaging for various products.

Decorative Packaging: Adds elegance and a premium look to luxury packaging, book covers, and invitations.

Labeling & Wrapping: Used for eye-catching labels and wrapping applications.

Insulation: Used in applications where its reflective properties can be beneficial, such as in survival blankets.

Specialty Applications: Can be used in fields like the optoelectronic and electronics industries, for wire and cable insulation, and in printing. 

Flexible Packaging: Widely used for food, beverages, and pharmaceuticals due to its barrier properties and food-safe nature.

Electronics: Utilized in flexible circuits, cable insulation, capacitor films, and advanced display technologies like OLEDs.

Industrial Applications: Found in cable wrapping, sheet forming, and transformer insulation films.

Labeling & Printing: Used for pressure-sensitive labels, printed films, and graphic applications due to its printability and dimensional stability.

Protective Coatings: Applied as protective coatings for windows, screens, and solar panels.

Other Applications: Used in medical and healthcare packaging, plastic cards, tape backing, and membrane switch overlays.
