Foshan Opalus Adhesive Products Co., Ltd manufactures 2 mil packing tape with a clear BOPP film backing and pressure-sensitive adhesive coating for applications where thickness is specified in mils. A 2.0 mil grade equals approximately 50.8 u/um total thickness, measured across the finished tape structure rather than the BOPP film alone. The finished thickness includes both the backing film and adhesive layer, which are important when reviewing carton sealing performance and production consistency.
Product Overview
2 Mil Clear BOPP Packing Tape is a carton sealing tape produced with a clear polypropylene film backing and adhesive coating layer. The 2.0 mil designation refers to finished tape thickness, not roll width. A 2 inch wide roll can be produced in different thickness grades, so width and thickness should always be reviewed separately.
The finished thickness is determined by the combined BOPP film structure and adhesive coating amount. During production inspection, thickness measurement, coating consistency, slit edge condition, winding quality, and roll appearance are reviewed together. These controls help maintain stable performance between approved samples and repeat production batches.
Thickness Grade Comparison: 1.8 Mil, 2.0 Mil and 2.2 Mil
| Thickness Grade | Approximate Thickness | Typical Selection Consideration |
|---|---|---|
| 1.8 mil | 45.7 u/um | Lower material usage for general carton sealing |
| 2.0 mil | 50.8 u/um | Balanced thickness grade for daily and medium carton sealing |
| 2.2 mil | 55.9 u/um | Higher thickness margin and increased stiffness |
The 2.0 mil grade is commonly selected when a balance between material usage, roll handling, sealing reliability, and packaging cost is required. A higher mil value does not automatically mean heavy duty performance because final results also depend on BOPP film strength, adhesive formulation, carton surface condition, and sealing method.
Benefits
- Maintains a controlled 2.0 mil total thickness grade for consistent carton sealing performance.
- Clear BOPP construction keeps carton labels and printed surfaces visible after sealing.
- Allows review of thickness, width, roll length, and core size before bulk production.
- Supports evaluation through peel adhesion, tensile strength, elongation, and holding power testing.
- Approved samples and retained references help compare repeat production batches.
What Is the Difference Between 2 Mil and 45 Micron BOPP Packing Tape?
The difference between 2 mil and 45 micron tape starts with the measurement system. Mil is an imperial thickness unit, while micron is a metric unit. Since 1 mil equals 25.4 u/um, a 2.0 mil tape is approximately 50.8 u/um in total thickness and should not be treated as a renamed 45 micron product.
When comparing a clear carton sealing tape produced in the 2.0 mil thickness range with a metric thickness grade, the complete tape construction should be reviewed, including BOPP film thickness, adhesive coating level, and thickness tolerance.

How Should 2 Mil Clear BOPP Packing Tape Be Verified Before Bulk Production?
Before bulk production, the tape should be checked against the agreed thickness grade and tested on the actual cartons used in the application. Verification normally includes total thickness measurement, width inspection, roll length confirmation, core size checking, and carton sealing trials.
Performance reviews may include peel adhesion, tensile strength, elongation, shear holding, unwind condition, and visual inspection after sealing. Retaining an approved sample and comparing future batches helps identify changes in thickness, winding quality, or slit edge condition.
FAQ
Does 2 mil packing tape mean the tape width is 2 inches?
No. 2 mil refers to total tape thickness, while inch normally describes roll width. These are separate specifications.
Is 2 mil the same as 50 micron BOPP packing tape?
A 2.0 mil grade is approximately 50.8 u/um, but the final comparison should include thickness tolerance and tape construction.
How should different thickness grades be selected?
Selection depends on carton material, sealing method, material usage, and required holding performance.
What should be confirmed before bulk production?
Confirm thickness, width, roll length, adhesive performance, approved samples, carton testing, and batch consistency.
