How to Choose the BOPP Film Thickness

When it comes to food packaging, selecting the correct BOPP film thickness isn’t just a technical detail—it’s a strategic decision that influences shelf life, cost, appearance, and product safety. As sustainability and efficiency become central to the packaging industry, more manufacturers are turning to Biaxially Oriented Polypropylene (BOPP) films for their excellent performance-to-cost ratio.

This article is your comprehensive BOPP thickness guide. We’ll walk you through how to choose the ideal BOPP film thickness for food packaging, based on product type, packaging function, cost considerations, and more.

Understanding the Thickness Range of BOPP Film

According to Kangzheng, a trusted BOPP film manufacturer in China, the typical thickness range of BOPP films is from 10μm to 45μm. Here’s how these layers are typically structured:

• Core layer: The thickest and mechanically strongest, providing tensile strength.

• Outer layers: These lend properties such as heat-sealability or printability. Metallized, matte, or anti-fog coatings may be applied here.

Common Thickness Levels & Their Uses

Food Type vs. Recommended BOPP Thickness

Examples:

• 15μm: Excellent for candy twist wraps and chocolate bars

• 23μm: Ideal for potato chips, bread bags, and inner layers of laminates

• 35μm: Best for frozen food pouches and bulk snack packs

BOPP Film Thickness vs. Packaging Cost

Thickness not only affects protection but also cost. Thicker films mean:

• ✅ Better mechanical strength

• ✅ Increased barrier properties

• ❌ Higher material costs

• ❌ Higher shipping weight
