40 micron thickness iml label in mold label for plastic lid injection molding
40 micron thickness iml label in mold label for plastic lid injection molding
In mold label (IML) is a pre-printed plastic film placed inside an injection mold before molten resin is injected. During molding, the label fuses with the plastic and becomes an integral part of the finished product. A 40 micron thickness iml label is a thin, lightweight option commonly used for plastic lid injection molding, offering high-quality graphics, durable surface protection, and an adhesive-free, seamless finish. The in mold label for plastic lid injection molding can resist scratching,moisture, and wear while reducing secondary labeling steps and improving production efficiency.

IML in mold label FAQ
Q:What are the influencing factors of the cut size of the IML in mold label and how to measure it correctly?
1) Mainly shrinkage.The label material and the shrinkage ratio of the injection molding machine will all affect the effect after injection molding. It is necessary to measure and test about the product material, label thickness and the shrinkage of the injection molding machine itself, and finally achieve the perfect effect, which can be completely seamless.
2) Make the correct cut size according to the product. It is best if the customer can provide product samples, and then we can make the cut size based on the samples.
Q:The reason why the IML label cannot be attached to the mold/Reasons for insufficient static electricity of IML labels:
1) There is no static electricity added to the label when it leaves the factory. It is equipped with an static charger/electrostatic generator to add static electricity.
2) The environment is humid and static electricity will run away during shipping. Equipped with an electrostatic device/static charger.
3) If you cannot add static electricity using an electrostatic generator, it may be related to the material of the label. Contact us to confirm the reason.
4) If it is manual injection molding,try using a wet rag and adding water.
5) If it is a robot, it may be caused by static electricity removal at the factory.
Q:The color of the IML label becomes darker after injection molding:
1) The base color of the product is too dark, you can use two layers of white when designing.
2) Thicken and deepen the white ink, or use high-concentration white.
Q:The label color is different from the design file:
1) The customer provides an electronic draft or sample label. After the customer confirms the
color and size, the maximum difference between the produced label and the design file is 5%.
2) Determine some spot color numbers according to the Pantone color card.
Production process
IML label production steps:
1. Make Cylinder (Gravure Plate Engraving)
The process begins with engraving a gravure printing cylinder. The customer's custom design is laser‑engraved onto a copper or chrome‑plated steel cylinder.
2. Printing (Gravure Printing)
The engraved cylinder is installed onto a gravure printing press. The cylinder rotates through an ink bath, filling the engraved cells with ink, while a doctor blade removes excess ink from the smooth surface. The cylinder then presses the ink onto the 40 micron OPP or PP film substrate.
3. Drying (Curing)
After each ink layer is applied, the printed film passes through a heated drying tunnel. Hot air evaporates the solvents from the ink, curing it firmly onto the film surface. Complete drying is essential to prevent smudging,ink transfer, or adhesion issues during subsequent handling.
4. Die‑Cutting (Slitting or Punching)
Once the master roll is fully dried, it is transferred to a die‑cutting or slitting machine.The large roll is cut into customer‑specified sizes – either slit into narrow rolls of specific widths (e.g., 100mm,120mm) or die‑cut into individual label shapes.
5. Quality Inspection
Each finished roll undergoes rigorous inspection. Key checks include:
Color accuracy – compared against approved color standards.
Print clarity – no blurring, misregistration, or missing details.
Surface defects – no scratches, bubbles, dust, or stains.
Dimensional accuracy – width, length, thickness (40 micron tolerance), and roll diameter verified.
Adhesion test – ensures the ink layer is properly cured and bonded.
Any defective material is rejected to maintain consistent quality standards.
6. Packaging
After passing inspection, the IML label rolls are carefully packaged. Each roll is wrapped in protective film to prevent dust, scratches, and moisture damage during storage and transit. The rolls are then placed into sturdy cartons, labeled with product details(size,design, batch number, thickness), and sealed for shipment.

FAQ
1.Are you a manufacturer?
2.Can you provide samples?
Yes, we can provide you samples for quality checking. Please let us know your requirements, then we can arrange samples according to your requirements. Our samples are free, but the delivery charge is on your side.
3.How can we guarantee quality?
Always a pre-production sample before mass production;Always final Inspection before shipment.
4.What is "IML"?
IML labels are a kind of decorative material that uses OPP/BOPP raw materials and prints customized design artwork on the raw materials through gravure printing technology. After the customer receives the IML label, when injecting the product, the label is placed in the film cavity of the product. Through injection molding, the label attached to the product is integrally formed, which has a good decorative effect.
