BOPP Film for Soft Packaging Printing Lamination
BOPP films are produced by extruding polypropylene resin into a sheet, which is then stretched and cooled in two orthogonal directions (broadly meaning "crosswise" and "lengthwise") to enhance its strength and clarity. This process increases the molecular orientation of the material, resulting in improved mechanical properties like tensile strength, tear resistance, and elongation.

BOPP (Biaxially Oriented Polypropylene) plastic film Here's an introduction to BOPP plastic film:
Manufacturing Process:
BOPP films are produced by extruding polypropylene resin into a sheet, which is then stretched and cooled in two orthogonal directions (broadly meaning "crosswise" and "lengthwise") to enhance its strength and clarity. This process increases the molecular orientation of the material, resulting in improved mechanical properties like tensile strength, tear resistance, and elongation.
Properties:
- High Transparency: BOPP films offer excellent clarity, making them suitable for packaging applications where product visibility is important.
- High Tensile Strength: They have a high tensile strength, which makes them durable and resistant to tearing.
- Water Resistance: BOPP films are highly water-resistant, making them ideal for packaging products that need to be protected from moisture.
- Chemical Resistance: They are resistant to most chemicals, ensuring they can be used for packaging products that might come into contact with chemicals during storage or transportation.
- Heat Sealability: BOPP films can be heat sealed, which is useful in manufacturing bags, pouches, and other types of packaging.
- Low Coefficient of Friction: This property makes them easy to print on and handle, reducing the risk of damage during the manufacturing process.
