BOPP film: The Perfect Flexible Packaging Solution

Table of Contents

BOPP film holds over 30% of the global flexible packaging market share, making it a critical material. Drawing on 15 years of industry experience, this article provides a detailed explanation of BOPP film to assist you in material selection.

What is BOPP film?

BOPP film is a plastic film manufactured from polypropylene, commonly utilized for packaging, labeling, and lamination. Produced via Ziegler-Natta catalytic polymerization, polypropylene exhibits exceptional flexibility (elongation >200%) and adapts well to complex surfaces, making it an ideal packaging substrate.

BOPP undergoes biaxial orientation (MD/TD ratio 3:1), enhancing strength by over 30% and significantly outperforming uniaxially oriented films. BOPP film is unrivaled in both visual appearance and mechanical and physical properties.

What are the characteristics of BOPP film?

BOPP film boasts comprehensive properties, making it highly valued within the packaging industry. Its principal characteristics include:

Optical Properties

BOPP film exhibits transparency >90% and gloss >85 GU, enhancing product presentation and consumer appeal.

Mechanical Properties

High Strength: BOPP film is robust and durable, exhibiting strong puncture and tear resistance. It remains intact during transit, providing reliable product protection.

Elongation: Elongation exceeds 400%, ensuring durability under high tensile forces (> 50 N/mm).

Abrasion Resistance: BOPP film exhibits excellent wear resistance, prolonging the longevity of product protection.

Electrical and Chemical Properties

Anti-Static Performance: Low electrical charge accumulation prevents static buildup, effectively repelling dust and maintaining surface cleanliness.

Chemical Resistance: Withstands corrosion from most acids, alkalis, and oily substances, preserving physical properties across diverse environments to ensure packaging integrity.

Barrier and Preservation Properties

Moisture and Water Resistance: BOPP film serves as an excellent moisture barrier, suitable for packaging moisture-sensitive products such as soda crackers and preserving food textures.

Gas Barrier Properties: BOPP film exhibits moderate oxygen barrier properties, which can be significantly enhanced through specialized treatments. Common treatments include metallized film and acrylic coating. These effectively prevent product oxidation, extending shelf life.

Varieties and Applications of BOPP Film

Clear BOPP Film:

The most commonly used base variant is clear BOPP film. This type offers excellent processability, enabling diverse processing according to specific requirements: WVTR < 5 g/m²·day, and a water barrier layer combined with pressure-sensitive labels for ink protection.

Applications: Food packaging, printed packaging, retail packaging
