Understanding Plastic Film Thickness – From Microns to Functionality

The plastic film thickness is a crucial specification that determines the strength, durability, flexibility, and application performance of the film. Whether used for packaging, protection, lamination, or industrial use, selecting the correct film thickness ensures optimal results and cost-efficiency.

At NAIGU, we manufacture plastic films in a wide range of thicknesses – from ultra-thin 10 microns to heavy-duty 200 microns – using materials like PE, PET, CPP, and biodegradable blends. All films are precisely measured using micrometers and undergo strict quality control to meet international standards.

Plastic Film Thickness Measurement Tools

Common Units for Measuring Plastic Film Thickness

  • Micron (μm): Most commonly used in industrial and packaging sectors. 1 micron = 0.001mm.
  • Gauge: Traditional imperial unit. 100 gauge ≈ 25.4 microns.
  • Mil: Used in North America. 1 mil = 25.4 microns = 0.001 inch.

Choosing the right thickness depends on how the film will be used. For example, food packaging requires barrier films of 20–80 microns, while industrial mattress packaging might use films of 100–200 microns for durability and puncture resistance.


Recommended Thickness by Application

Application Recommended Thickness Material
Retail Packaging Bags 40–60 microns PE, BOPP
Mattress Packaging 100–150 microns PE, HDPE
Shrink Film for Logistics 60–100 microns LDPE, POF
Food Packaging 20–50 microns PET, CPP, EVOH multilayer
Protective Furniture Wrap 80–120 microns PE, LLDPE

Why Plastic Film Thickness Matters

  • Influences strength, tear resistance, and puncture performance
  • Affects flexibility and foldability
  • Impacts printability and lamination process
  • Determines roll weight and transportation cost
  • Regulates barrier properties (for moisture, oxygen, aroma)

Choosing the wrong thickness can result in overpackaging or damage during handling. NAIGU provides custom recommendations based on your product, environment, and machinery.
