PP Yogurt Cup IML Label Injection Molding

Zhongyu's China PP Yogurt Cup IML Label Injection Molding can achieve integrated printing of cartoon characters, multi-flavor color zoning, storage conditions, ingredient instructions, traceability QR codes, and warning signs. The colors are rich, and the character lines are clear and well-represented. It is suitable for multi-flavor molds with quick replacement for rapid production of different appearance cups.

Custom IML Waterproof In Mold Label for Food Packaging Product Specifications

Why it is suitable for yogurt cups?

Low-temperature yogurt and pudding need to be refrigerated at 2-6℃ throughout the process. The outer wall of the cup accumulates condensation water for a long time. Ordinary stickers are prone to delaminate and bubble when exposed to water vapor, and screen printing is easily worn off by wiping.

The IML label pattern is embedded in the cup body layer, and it remains intact and stable even when in contact with condensation water vapor for a long time. Food terminals need frequent stacking transportation, box loading and handling, and the labels are resistant to friction. The patterns will not be scratched during the circulation process.

Food enterprises often launch multiple flavors. With the same injection mold, only the IML labels need to be replaced to produce cups with different appearances. There is no need to modify the mold, which reduces the cost of new product mold development and shortens the new product launch cycle.

The label and PP cup body material are of the same origin. The labels do not need to be separated for recycling, which is in line with the environmental packaging demands of food brands.

IML Label Injection Molding Production Process

1. Gravure printing on PET/PP film and Lamination

2. Cutting into standard label sheets

3. Automatic robot places labels into injection mold cavity

4. Plastic melt injection, film and plastic melt into one piece

5. Demold finished IML plastic products directly

Material

Our PP Yogurt Cup IML Label Injection Molding uses food-contact grade multi-layered IML special film, which is suitable for food injection molding environment. The ink is selected as low-temperature food-grade printing ink, meeting the relevant domestic food contact material standards. It does not release harmful substances even under high-temperature injection molding.

The film material has good tensile and elongation properties. After the cup mouth and cup bottom deformation positions are stretched, the patterns do not deform or show broken lines or missed printing, and is suitable for thin-walled PP yogurt cup injection molding.

FAQ

Q1: Will there be any pattern abnormalities if the PP Yogurt Cup IML Label Injection Molding is repeatedly soaked in cold water?

A: The graphics are sealed inside the cup body and are not eroded by the cold water. Aging verification can be conducted in a simulated refrigerated environment.

Q2: With the same flavor but using the same mold, can the IML labels be quickly switched?

A: Yes, only the label sheet needs to be replaced. The mold does not need to be modified, enabling rapid production of cups with multiple flavors.

Q3: Can your food-related IML labels provide a food contact testing report?

A: For each batch of orders, corresponding batch material test data can be provided to meet the requirements of food factories.

Q4: Will the thin-walled yogurt injection molded cups deform or become blurry after injection and stretching?

A: During the initial stage, compensation for the cup body deformation is combined. After sample confirmation, the production process is then implemented for large-scale production.

Q5: For new project development, what is the minimum number of samples that can be made for testing?

A: Support for small-batch samples. The sample production process is consistent with the large-scale production process.

Q6: Are the film materials and inks all controlled by your company, and is there any outsourcing printing?

A: The printing processing of food-related IML labels is all completed in the factory, and the entire process is traceable.

Q7: After the IML label is formed, can the cups still undergo heat sealing processing?

A: The label does not affect the heat sealing area of the cup mouth. The cup mouth design needs to be confirmed in advance.
