Treatment method
Although non-polar polymers such as polyethylene and polypropylene have poor affinity for ink, satisfactory printing effects can still be obtained after proper treatment. Therefore, necessary treatment of plastic film before printing is a key step to ensure the quality of printed materials. To improve the printing effect, appropriate surface treatment, such as corona, flame or acid treatment, must be carried out, which can increase the polarity of the film and improve its printing performance. The treatment method usually involves increasing the polarity of the plastic film by oxidation, thereby changing its surface structure. These methods include discharge (such as corona or spark) treatment, flame treatment, ultraviolet radiation treatment, and treatment with acid (such as sulfuric acid or chromic acid). Among them, corona treatment is highly regarded for its simplicity and popularity.
The effect of corona treatment is affected by many factors, including the output power of the treatment equipment, the distance between the two electrodes, the discharge area of the electrodes, the treatment speed, and the treatment method and number of times. The treated film should be printed immediately, otherwise it may fail.
During the EDM process, the polymer may cross-link due to the free radical reaction generated by corona discharge, resulting in a rough surface and enhanced wettability to polar solvents. This treatment can usually significantly improve the printing properties of plastic films.
In addition, to further improve the printing effect, antistatic additives such as trihydroxylaurylamide ethyl quaternary ammonium perchlorate can be used to enhance the static charge decay effect, thereby improving the adhesion of the ink. In gravure and chiral printing, the wettability of solvent-based inks has been further optimized.
Printing method
Plastic films use flexographic, gravure and screen printing technology, and it is particularly important to choose the right ink, especially gravure printing often uses synthetic resin and pigment blended ink. The printing methods of plastic films mainly include flexographic printing, gravure printing and screen printing. For gravure plastic films, the commonly used ink is a colloidal fluid formed by fully grinding and dispersing synthetic resins, alcohol organic solvents and pigments. This ink has good fluidity, printing performance and rapid drying, and is particularly suitable for gravure rotary printing on polyethylene, polypropylene and other films.
Troubleshooting IML Printing Issues： A Comprehensive Guide
In-Mold Labeling (IML) is a highly efficient and popular packaging method used across a wide range of industries, including food and beverage, consumer goods, and cosmetics. However, like any manufacturing process, IML printing can face its own set of challenges. In this blog, we'll answer common questions and provide practical tips to help you troubleshoot and optimize your IML printing process.
➤Q1: What are the most common IML printing issues?
IML printing is a complex process that requires precise control over several factors. Here are some of the most frequent issues faced by manufacturers:
●Ink Smearing or Smudging
█Cause: Poor ink adhesion or improper curing.
█Solution: Ensure that the correct ink type is used for the specific material . Also, check that the curing system is properly calibrated to ensure complete curing.
●Label Positioning Problems
█Cause: Misalignment of labels during the injection molding process.
█Solution: Adjust the mold alignment and ensure that the label is properly placed before injection. You may also need to check for any irregularities in the mold's surface.
●Bubbles and Wrinkling on Labels
█Cause: Air trapped between the label and the mold or uneven heating.
█Solution: Ensure that the mold temperature is consistent and that the label is free of any contaminants before applying it.
●Print Defects (e.g., Fading, Inconsistent Colors)
█Cause: Incorrect ink viscosity or improper printing conditions.
█Solution: Review your ink formulation and printing parameters. Ensure that the printer's settings, including pressure, temperature, and speed, are properly adjusted.
➤Q2: How can I improve ink adhesion for better IML print quality?
Ink adhesion is critical for achieving a durable, high-quality print on IML labels. Here are some tips to improve ink adhesion:
●Surface Treatment:
Treat the substrate to enhance its surface energy. Methods like corona treatment or plasma treatment can increase the bonding strength between the ink and the label.
●Choosing the Right Ink:
Use inks that are specifically designed for IML applications. UV-cured inks are highly recommended for their fast drying times and excellent adhesion properties.
●Correct Temperature Control:
Maintaining the proper temperature during printing and curing ensures that the ink adheres properly. Overheating or underheating can lead to adhesion failure.
●Consistency in Ink Viscosity:
Monitor and adjust ink viscosity regularly. If it's too thick, the ink may not adhere correctly, while if it's too thin, the print may be too light or unclear.
➤Q3: What are the technical specifications to consider for IML printing?
When it comes to technical specifications for IML printing, several factors must be taken into account:
●Printer Resolution:
A printer with a resolution of at least 300 dpi is recommended to achieve sharp and clear prints.
●Ink Compatibility:
Ensure that the ink is compatible with the molding material (PP, PET, PE, etc.) and can withstand the conditions it will be exposed to.
●Mold Temperature:
Typical mold temperatures range from 180°C to 200°C. Consistent control of mold temperature is crucial to prevent defects like warping or improper label adhesion.
●Curing Time:
The curing time for UV inks typically ranges from 3 to 6 seconds depending on the lamp intensity and material. Over-curing can cause embrittlement, while under-curing can result in poor adhesion.
●Injection Pressure:
Maintaining a consistent injection pressure of around 700 to 1200 bar is essential to ensure proper mold filling and label placement.
➤Q4: How can market trends influence IML printing processes?
IML is growing rapidly due to its superior aesthetic appeal, efficiency, and sustainability. Market trends play a key role in shaping IML printing processes. Here are some trends to watch:
●Rising Demand for Sustainable Packaging:
According to Grand View Research, the global IML market size is expected to reach $8.7 billion by 2027, driven by consumer demand for eco-friendly packaging.
●Impact: This increased demand for recyclable and biodegradable materials means that IML printers must adopt inks and materials that meet sustainability standards without compromising quality.
●Advancements in Technology:
Automation and smart molding technologies are making it easier to handle more complex designs and achieve higher print quality with fewer defects. This trend is especially important for brands that require high-definition prints.
●Shorter Lead Times and Faster Turnaround:
As the e-commerce market expands, there’s increasing pressure to deliver packaging faster. According to a 2024 Packaging Trends report, manufacturers are focusing on improving the speed of IML production while maintaining print quality.
●Customization and Personalization:
Consumers are increasingly looking for personalized packaging, leading to a rise in demand for customized IML labels. This trend is pushing the industry to innovate in terms of design and printing capabilities.
➤Q5: How can I optimize my IML printing process for efficiency?
Maximizing efficiency in IML printing requires balancing speed, quality, and cost. Here are a few strategies:
●Invest in High-Quality Equipment:
High-performance printers and molders can significantly reduce the frequency of errors and defects. Opt for machines that allow for quick setup changes and consistent results.
●Monitor and Adjust Environmental Conditions:
Make sure that temperature, humidity, and airflow in the printing environment are consistent. These factors can affect ink drying, curing, and adhesion.
●Regular Equipment Maintenance:
Schedule routine maintenance checks for your printers and molds. Timely calibration and cleaning can prevent downtime and ensure optimal performance.
