When using BOPP (Biaxially Oriented Polypropylene) film for in-mold labeling (IML) in injection molding, several challenges may arise during printing, processing, and molding. Below is a detailed breakdown of common problems and corresponding solutions.
1. Printing Issues
Problems:
● Ink adhesion problems: BOPP film has a smooth, non-porous surface, making ink adhesion difficult.
● Ink drying issues: Some inks dry too slowly on BOPP, leading to smudging or incomplete curing.
● Color variation or poor opacity: The ink may not appear as expected due to the film’s transparency or reflectivity.
Solutions:
✅ Use IML-compatible inks, such as UV-curable or solvent-based inks, to improve adhesion.
✅ Perform surface treatment (e.g., corona treatment or primer coating) to increase surface tension and ink bonding.
✅ Choose white or opaque BOPP films for better color consistency and opacity.
2. Static Electricity Problems
Problems:
● Film sticking together: High static charge causes BOPP labels to stick, making feeding and handling difficult.
● Dust attraction: Static buildup attracts dust and debris, which can affect print quality and mold adhesion.
Solutions:
✅ Use anti-static treatments or coatings on the BOPP film to reduce static buildup.
✅ Install ionizing bars in the production line to neutralize static charges.
✅ Maintain proper humidity levels in the production environment to minimize static electricity.
3. Die-Cutting and Label Handling Issues
Problems:
● Poor die-cutting precision: BOPP’s toughness can cause rough or uneven cuts.
● Edge curling: Improper cutting or tension control may lead to curled labels, affecting placement in the mold.
● Film tearing or warping: Incorrect tension during processing can damage the labels.
Solutions:
✅ Use sharp, high-precision dies and optimize cutting pressure for clean edges.
✅ Control web tension in the cutting process to prevent label warping.
✅ Use multi-layer BOPP films that provide better stiffness and stability.
4. Adhesion and Bonding Problems in the Injection Mold
Problems:
● Label shifting inside the mold: If the label does not stay in place, it can cause misalignment or defects.
● Weak bonding with plastic: BOPP film may not adhere well to the injected plastic, leading to peeling.
● Wrinkling or air bubbles: Poor label positioning or excessive mold temperature can cause defects.
Solutions:
✅ Use static charge or vacuum systems to hold the label in place before injection.
✅ Ensure the film is coated with a suitable anchoring layer for better adhesion to the molded plastic.
✅ Adjust mold temperature and injection pressure to minimize air entrapment and improve label integration.
5. Temperature and Shrinkage Issues
Problems:
● Film shrinkage or distortion: High temperatures during molding can cause the BOPP label to shrink unevenly.
● Dimensional stability problems: If the film expands or contracts too much, it can lead to misalignment.
Solutions:
✅ Use high-heat-resistant BOPP films specifically designed for IML applications.
✅ Ensure proper label conditioning before molding to minimize expansion or shrinkage.
✅ Control mold temperature and injection cycle time to reduce thermal stress on the label.
6. Environmental and Storage Problems
Problems:
● Film brittleness in low temperatures: BOPP can become brittle in cold storage conditions.
● Moisture-related issues: High humidity can affect ink adhesion and cause film distortion.
Solutions:
✅ Store BOPP film in a controlled environment with stable temperature and humidity.
✅ Use protective packaging to prevent dust and moisture exposure.
✅ Allow films to acclimate to room temperature before printing and molding.

When using metallized paper for label production, several common issues may arise. Below is a list of potential problems and corresponding solutions:
1. Printing Issues
Problems:
● Poor ink adhesion: The smooth metallized surface makes it difficult for regular inks to adhere, leading to ink peeling or blurring.
● Slow drying speed: The metallized layer reduces ink absorption and evaporation, causing longer drying times and lower production efficiency.
● Low color reproduction accuracy: The reflective nature of the metallized surface can affect color presentation, leading to deviations in print color.
Solutions:
✅ Use specialized inks (such as UV or water-based inks) to improve adhesion and drying speed.
✅ Apply corona treatment or pre-coating to increase surface energy and improve ink adhesion.
✅ Use a white base layer or adjust color management settings to compensate for the reflective effect.
2. Coating and Surface Treatment Issues
Problems:
● Poor adhesion of UV varnish or lamination: The low surface energy of the metallized paper may cause coatings or varnish layers to peel off.
● Low surface tension: This can affect ink, coating, and adhesive performance, leading to poor processing results.
Solutions:
✅ Use corona treatment or pre-coating layers to increase surface energy, improving the adhesion of UV varnish, lamination, or top coatings.
✅ Choose specially formulated UV varnish or water-based coatings designed for metallized paper.
✅ Store the paper in a dry environment to prevent moisture from affecting the metallized layer.
3. Die-cutting and Processing Issues
Problems:
● Edge cracking or aluminum layer peeling: The metallized layer may detach during die-cutting, affecting the label’s appearance.
● Aluminum layer separation after cutting: The metallized coating may peel off when the label is bent or folded, reducing product quality.
Solutions:
✅ Use high-quality die-cutting blades and optimize pressure settings to prevent cracking or peeling.
✅ Choose flexible metallized paper to enhance adhesion and resistance to folding.
✅ Adjust the die-cutting angle to minimize direct impact on the metallized layer, reducing peeling risks.
4. Adhesion Issues
Problems:
● Weak adhesive bonding: The metallized layer can interfere with glue adhesion, making labels difficult to stick.
● Bubbles or detachment: Adhesives may form bubbles or fail in high humidity or high-temperature environments.
Solutions:
✅ Use adhesives specifically designed for metallized surfaces, such as high-adhesion solvent-based adhesives.
✅ Apply a primer or coating layer to enhance the adhesive’s bonding ability.
✅ Control humidity levels to prevent moisture absorption, which could impact adhesion performance.
5. Durability and Storage Issues
Problems:
● Moisture absorption and warping: Metallized paper has higher moisture sensitivity, leading to deformation when improperly stored.
● Poor heat resistance: High temperatures may cause oxidation or discoloration of the metallized layer.
Solutions:
✅ Store in a dry and temperature-controlled environment (recommended humidity < 50%, temperature 20-25°C).
✅ Use moisture-proof packaging to prevent humidity damage during storage and transportation.
✅ Avoid direct sunlight and high temperatures to prevent oxidation or discoloration of the metallized layer.
6. Environmental and Regulatory Issues
Problems:
● Difficult to recycle: Some metallized papers are harder to recycle due to the presence of the aluminum layer.
● Food safety concerns: Some metallized coatings may not comply with food packaging regulations.
Solutions:
✅ Choose eco-friendly and recyclable metallized paper, such as water-based coated metallized paper.
✅ Ensure compliance with FDA, EU, and other food safety standards, especially for food packaging labels.
✅ Reduce the use of solvent-based chemicals in production and adopt environmentally friendly coating technologies to lower pollution risks.
