1. Poor Label Release
Causes:
● Inadequate or low-quality adhesive.
● Incorrect label applicator settings (too much or too little pressure).
● Static electricity causing labels to stick together or release unevenly.
Solutions:
✅ Use a suitable adhesive (pressure-sensitive or heat-activated) for better bonding.
✅ Adjust labeling machine pressure and speed for smoother label release.
✅ Apply anti-static coatings or control humidity to reduce static-related issues.
2. Bubbling or Wrinkling After Application
Causes:
● Air trapped under the label during application.
● Improper tension or pressure in the labeling process.
● Contaminants on the bottle surface, such as oil, dust, or moisture.
Solutions:
✅ Use a flexible BOPP film that conforms well to bottle curves.
✅ Adjust the label applicator settings to apply even pressure across the label.
✅ Ensure bottle surfaces are clean and dry before labeling.
3. Poor Print Quality
Causes:
● Incompatible ink or poor ink adhesion to BOPP film.
● Incorrect printing machine settings, affecting ink distribution.
● Inadequate pre-treatment of BOPP film (such as missing corona treatment).
Solutions:
✅ Choose UV, flexographic, or gravure inks that adhere well to BOPP film.
✅ Ensure BOPP film has undergone corona treatment (surface energy ≥38 dyn/cm).
✅ Optimize printing machine settings, such as pressure, speed, and drying time.
4. Misalignment During Label Application
Causes:
● Labeling machine misalignment or improper sensor calibration.
● High-speed application causing labels to shift or slip.
● Poor flexibility of the BOPP film, leading to misplacement.
Solutions:
✅ Adjust the labeling machine sensors to ensure precise label positioning.
✅ Use a rigid and dimensionally stable BOPP film to minimize deformation.
✅ Reduce labeling speed if necessary to allow better alignment.
5. Edge Lifting or Peeling Off
Causes:
● Environmental changes (temperature/humidity) affecting adhesion.
● Uneven thickness of BOPP film causing shrinkage or curling at edges.
● Incompatible adhesive that fails under storage or transportation conditions.
Solutions:
✅ Choose BOPP film with high moisture and temperature resistance.
✅ Ensure label film thickness is consistent to prevent curling.
✅ Select adhesives suited for specific storage and transportation conditions (e.g., low-temp or heat-resistant adhesives).
6. Inconsistent Shrink Performance (For shrink wrap label films)
Causes:
● Uneven heat distribution in the shrink tunnel.
● Mismatch between BOPP shrink properties and bottle shape, leading to wrinkles.
Solutions:
✅ Use an even heat distribution system (hot air or steam shrink tunnels).
✅ Select the right BOPP film thickness and material to match the bottle’s shrink rate.
Summary Table
BOPP wrap label film issues often arise due to labeling process inefficiencies, material selection, printing compatibility, and storage conditions. To ensure optimal performance:
1. Choose the right BOPP film type (transparent, pearlescent, metallized, etc.).
2. Use compatible adhesives and printing inks.
3. Optimize labeling machine settings (pressure, speed, alignment).
4. Control storage conditions to avoid extreme temperature or humidity effects.
