FL18 : Pearlised BOPP
What is Pearlised BOPP Film?
Pearlised BOPP (Biaxially Oriented Polypropylene) is a special type of plastic film known for its pearly white appearance, lower density, and excellent light barrier. It's widely used in flexible packaging due to its aesthetic appeal, cost-effectiveness, and functional benefits.

Key Features of Pearlised BOPP Film
• Pearly white opaque appearance
• Lightweight due to lower density (~0.60–0.65 g/cm³)
• Excellent light and moisture barrier
• Good printability with corona treatment
• Available in sealable grades
• Recyclable under PP stream

How is Pearlised BOPP Made?
Pearlised BOPP is produced by blending polypropylene resin with voiding agents like calcium carbonate. When the film is stretched biaxially (machine and transverse directions), micro-voids form, giving it a pearlescent look and reduced density.
Manufacturing Steps:
1. Blending resin with voiding agents
2. Extruding into a flat sheet
3. Casting on a chill roll
4. Biaxial orientation (MD & TD)
5. Heat setting
6. Surface treatment (typically corona)

Applications of Pearlised BOPP in Flexible Packaging
Food Packaging:
• Ice cream wrappers
• Biscuits and cookies
• Snacks and confectionery
• Instant noodles
• Dairy powders
Non-Food Applications:
• Soap and cosmetic wrappers
• Labels for hygiene products
• Personal care sachets
Sustainable Packaging:
• Used in mono-material structures (e.g., BOPP/BOPP or BOPP/CPP) for easier recycling

Cost Advantage of Pearlised BOPP
Due to its lower density, pearlised BOPP provides more square meters per kilogram, reducing cost per pack. It's also cost-effective because it:
• Eliminates the need for white ink
• Can be used in mono-web (single-layer) applications
• Requires no lamination in some cases (e.g., ice cream wrappers)

Sustainability Benefits
Pearlised BOPP supports recyclable packaging by enabling mono-material laminates. It also reduces plastic consumption due to its lower weight.

Frequently Asked Questions
Q1: Is pearlised BOPP film food safe? Yes, food-grade certified variants are widely available.
Q2: Can pearlised BOPP be printed? Yes, when surface-treated. It supports gravure and flexo printing.
Q3: Is it recyclable? Yes, it is recyclable under polypropylene recycling streams.
Q4: Is it heat sealable? Yes, sealable grades are available for FFS and flow-wrap.
Q5: How is it different from white PET? White PET is denser, stronger, and used for high-end laminates. Pearlised BOPP is lighter and better for cost-sensitive applications.
