Thermoforming

Applications

• BOPS film is characterized by high transparency and gloss, and by its resistance to acid and alkaline solutions, salts, soaps, and detergents. It is odorless, neutral in flavor, and easy to cut and print.
• BOPS film is mainly used as thick film for thermoforming applications or thin film for flexible packaging applications.
• Thermoforming The largest application for BOPS is thermoforming.
• Due to its high transparency and gloss, as well as its good stiffness and formability, BOPS sheets are converted into food trays and containers for fresh produce, pastries, and desserts. BOPS is also used for blister packaging of medical products, cosmetics, and electronic gadgets.
• Labels and sleeves BOPS film is printed and converted into labels and sleeves for bottles and containers, as well as for in-mold labeling.
• Laminated film BOPS, laminated with aluminum, is used for production of lids (e.g. dairy products). High transparency film Due to its transparency and stiffness, thin BOPS film is used for envelope windows
