The Science Behind In-Mould Labeling: Ensuring Quality in 900ml Ice Cream Tub Packaging



In the world of packaging, innovation is constantly at play. One such innovation that has transformed the way we perceive packaging is in-mould labeling (IML). For 900ml ice cream tubs, in-mould labeling is more than just a decorative feature; it’s a science that ensures both quality and aesthetics. In this article, we’ll delve into the fascinating science behind in-mould labeling and how it guarantees top-notch quality for your favorite frozen treats.

Understanding In-Mould Labeling (IML):

In-mould labeling is a process where labels are integrated into the packaging during its manufacturing phase. In the context of 900ml ice cream tubs, these labels are not merely added for visual appeal, but they play a critical role in ensuring the tubs’ overall quality.

The Process:

IML involves the following key steps:

  1. Mold Preparation: A specialized mold is created, which includes the desired label design and information.
  2. Injection Molding: During the manufacturing process, the plastic material for the ice cream tub is injected into the mold. At this stage, the label is fused seamlessly with the tub’s material.
  3. Cooling and Solidifying: The material cools and solidifies, resulting in a tub with an integrated label. This fusion is permanent and resistant to wear and tear.

Benefits of IML in 900ml Ice Cream Tubs:

  1. Durability: IML labels are resistant to moisture and abrasion, making them perfect for ice cream packaging, which often encounters condensation and handling.
  2. Vibrant Graphics: The fusion of labels with the tub material allows for high-resolution, vibrant graphics that make your ice cream packaging stand out on the shelves.
  3. Consistency: IML ensures consistent label placement and alignment, eliminating the possibility of misaligned or wrinkled labels.
  4. Environmentally Friendly: IML reduces waste compared to traditional labeling methods since there’s no need for separate label application.

Quality Control and Assurance:

To guarantee top-notch quality in 900ml ice cream tubs with IML, manufacturers employ rigorous quality control measures. These may include:

  • Thickness Testing: Ensuring uniform thickness across the tub, which is crucial for structural integrity.
  • Label Adhesion Testing: Checking the label’s adhesion to prevent peeling or detachment.
  • Visual Inspections: Examining each tub for any defects or imperfections in the label or structure.


In-mould labeling is not just a decorative feature; it’s a science that ensures the highest quality for 900ml ice cream tubs. From durability and vibrant graphics to eco-friendliness and consistency, IML offers a host of benefits that enhance both the product and the consumer’s experience. The next time you enjoy your favorite ice cream from a 900ml tub with an in-mould label, remember that there’s a fascinating science behind it that ensures excellence in packaging.

Investing in IML technology for your ice cream packaging can make a significant difference in product quality and consumer perception. Stay ahead in the packaging game by embracing the science of in-mould labeling.
