    Packing Specification

    Winding film+ double layer vacuum bag+ bubble wrap + plywood case

    Shelf Life of Product

    24 months (Unpacked)

    Instructions for use of INNOLAMIN™ ionoplast interlayer - IPL

    1. This product is packaged in two vacuum bags at the time of factory shipment, primarily to protect the product from external moisture.
    2. After opening, it must be stored in an environment with a temperature ≤25°C and humidity ≤30%. Due to the ionic nature of the interlayer film, it easily reacts with moisture in the air, leading to an increase in water content. This can reduce the material's transparency and optical performance, degrade its mechanical properties, and damage its internal structure, affecting its overall stability and ultimately rendering the product unusable.
    3. Improper handling of the product during storage can cause a significant number of bubbles to form in the laminated glass and a drastic reduction in adhesion to the glass.
    4. Slice open one long side of the packaging bag with a knife, Gently shake the bag and remove the INNOLAMIN™ Ionoplast-IPL.
    5. During the removal and handling process, it is essential for operators to wear lint-free gloves and attire that is both dust-proof and anti-static. This precaution prevents contamination within the laminated glass, which can occur due to electrostatic attraction of impurities from the INNOLAMIN™ Ionoplast-IPL.
    6. During intermittent production, it is necessary to seal the INNOLAMIN™ Ionoplast-IPL packaging bag with either tape or a heat sealer. This measure prevents the LGML™ Ionoplast-IPL from being exposed to the atmosphere and absorbing moisture, which could result in reduced bonding performance.
    7. It is advisable to measure the moisture level of INNOLAMIN™ Ionoplast-IPL using the thermogravimetric method prior to each production run. This ensures that the moisture content of the film remains below 0.2%.

    Rolling Process Control

    1. The operator should verify the tin side of the incoming glass to ensure the laminated glass structure is arranged as follows: empty/tin/INNOLAMIN™ IPL/tin/empty. Due to the ionic bonding method between the INNOLAMIN™ IPL interlayer and the glass, ensuring the tin surface of the glass faces the interior of the laminated glass enhances bonding strength and extends the product's lifespan.
    2. Maintain the quality of the water in the washing machine, preferably using deionized water, to eliminate impurities such as organic residues after cleaning the glass. This will prevent stains and minimize adhesion issues between the INNOLAMIN™ IPL and the glass, as well as keep the interior of the laminated product free from contaminants.
    3. When manufacturing tempered laminated glass, it is crucial to meticulously control the flatness (bow and wave) of the tempered glass and ensure the precise alignment of the two glass pieces to enhance the edge sealing quality.
    4. Before laminating the sheets, workers should use a glue roller to remove any impurities from the  Ionoplast-IPL. This includes contaminants embedded within the Ionoplast-IPL, those adsorbed onto the surface, and any particles that may have inadvertently settled on the film.
    5. When cutting Ionoplast-IPL, employ a wallpaper knife to trace an outline along the template, and then pull apart the Ionoplast-IPL along the scored lines.

          6. Rolling process parameters are as follows

    Rolling Process Parameters
    Glass Thickness Clip 1.52mm FilmPreheating Zone Temperature (℃)The Temperature of the First Area of the Main Box (℃)The Temperature of the Second Area of the Main Box (℃)Rolling Speed (m/min)
    6+1.52+61501901901.4 or 1.5
    8+1.52+81502002001.0 or 1.2
    10+1.52+101502102000.9 or 1.0
    12+1.52+121502102000.7 or 0.8

    The above parameters are for reference only, each unit can reasonably adjust the parameter design (temperature and speed) according to the glass length, layout size, and equipment conditions.

    7.For all types of coatings (such as color glaze surfaces, sunshine film surfaces, and low-E film surfaces) that come into contact with INNOLAMIN™ Ionoplast-IPL in synthetic laminated glass, it is essential to perform compatibility and bond performance tests to assess the product's machinability and quality.

    8.Given the rigidity of INNOLAMIN™ Ionoplast-IPL, prepressing the initial set of rollers is typically unnecessary. Instead, only the second set of rollers after the main heating furnace should be employed for single-layer applications. (Note: For multi-layer applications, ensure the upper and lower glass are secured with high-temperature adhesive to prevent misalignment.)

    9.The gap for the second set of rollers should be 3mm less than the glass's nominal thickness. The surface temperature of these rollers should maintain 65±3℃. Adjust the roller speed based on the glass surface temperature and the edge sealing condition post-prepressing.

    10.Following prepressing, the spacing of the glass on the stacking shelf should be at least the glass's nominal thickness. Additionally, using metal rods as spacers is not advisable as they can disrupt normal airflow between the glass sheets, causing uneven heating and cooling, and resulting in light distortion due to uneven force on the glass surface.

    11.The heat preservation temperature of the autoclave is not lower than 135℃, the heat preservation time is not less than 90min, the working pressure is 11.5～12.8bar, and the exhaust temperature is not higher than 42℃.

    Vacuum extractiom process:

    For laminated glass consisting of more than two layers or multiple layers of film, rolling is not recommended. Instead, use the vacuum process. The laminated glass can be pre-rolled without complete edge sealing, followed by vacuum bag treatment (cold pumping). For larger glass layouts or numerous interlayers, it is advisable to use additional suction silica gel tubes to maintain the vacuum level within the vacuum bag.

    Storage and Transportation:

    1.The temperature is lower than 25℃, and the humidity is lower than 30%.
     
    2.Keep the product away from direct sunlight, ensure it is waterproof and moisture-proof, maintain a distance from heat sources, and avoid applying pressure.
     
    3.Store any unused film properly. Before the next use, it is advisable to create a sample glass with an area of at least 0.5㎡ to verify product quality.
     
    4.Store INNOLAMIN™ IPL high-strength ionoplast interlayer material in rolls inside vacuum moisture-proof bags. These interlayer materials can be kept at normal temperatures while sealed. However, once the vacuum moisture-proof bags are opened, the material should be used promptly. Any unused product should be resealed and stored in a controlled temperature and humidity environment.

    5.It is advisable to use the purchased interlayer within two years from the purchase date to minimize any potential decline in bonding performance.
