Injection Molding PP Yogurt Cup with IML Label

The high-quality Injection Molding PP Yogurt Cup with IML Label supplied by Zhongyu can be directly used for refrigerating dairy-based jelly and fruit puddings, fully accommodating all the layout information required by food regulations, supporting the simultaneous development of multiple SKU fruit flavors, serving the mass production of food brands, and being suitable for domestic food distribution and export food packaging projects.

Differentiation Engineering

Unlike the general IML label scheme, we have conducted specialized engineering adjustments for thin-walled containers of pudding type.

The cup wall of pudding cups is thin, and the curved surface has a large arc. At the same time, the layout includes both large-area real-life fruit color pictures and a large number of high-density small characters and barcode areas.

We do not apply general film parameters. Instead, we make regional manuscript compensation based on the cup's curvature and the stretching ratio at various locations, distinguishing the stretching deformation of the picture area and the barcode area to ensure that the real-shot image does not deform after injection molding, and the small nutritional text and barcode can still be clearly scanned and recognized.

At the same time, we also consider the entire food production line conditions at the back end, evaluate the die-cutting edge of the label, the winding tension of the material, and match high-speed automatic label embedding injection molding equipment.

At the same time, we also evaluate the heat-sealing area of the cup mouth to avoid interference from the label on the aluminum foil sealing effect, and connect the entire process chain from injection molding, filling, heat sealing to low-temperature storage, achieving process adaptation rather than just meeting the printing appearance effect.

Industry pitfalls experience

Many food customers encounter hidden problems when doing IML: the sample appearance is qualified, but the actual fruit scene patterns have weak dots, the nutrition text is stretched and deformed, and the barcode scanning fails after mass production.

The problem lies in the fact that the stretching ratios of different parts of the thin-walled cup are different. The general label only simply scales the text manuscript, lacking zone deformation compensation； some manufacturers only look at the printing sample and do not do on-machine injection simulation verification.

In the early stage of our project, we conducted simulation injection tests to verify the actual state of the images, texts, and barcodes after molding, intercepting the risks of image distortion and barcode failure at the sample stage, avoiding the scrapping of large quantities of finished product packaging by food enterprises.

FAQ

Q1: The complex layout featuring large-scale real fruit images and detailed small barcodes can still be recognized after injection molding. Will the barcodes remain stable and readable after mass production?

A: We conducted pre-processing for deformation compensation and carried out on-machine simulation verification to ensure that the barcodes remain stable and readable after mass production.

Q2: Will the Injection Molding PP Yogurt Cup with IML Label affect the heat-sealing sealing performance of the cup opening?

A: We evaluated the cup opening layout in advance and ensured that the label avoids the heat-sealing area, thus not interfering with the sealing process.

Q3: Can you provide the relevant food contact inspection documents for the corresponding order batch?

A: Yes, we support this. For each batch, we can issue corresponding material inspection reports for internal factory audits and reviews.

Q4: For the new project development, which drawings need to be provided to us for process assessment in the early stage?

A: Providing the 3D drawings of the cup body is sufficient to complete the analysis of the stretching ratio and draft modification suggestions.

Q5: Does your company complete the entire printing and processing of the food IML labels in-house?

A: The entire food IML process is internally produced, without outsourcing procedures. The production records can be fully traced.

Q6: For mass production, will there be significant color differences in the colorful fruit images between different batches?

A: We will establish a color profile and dot gain process file. Each batch will be compared with the sample sheet to control the color.

Q7: For the IML label finished products of pudding, will there be a potential problem of label delamination after refrigeration storage?

A: We conduct low-temperature circulation simulation tests internally to verify the stability of the label's connection with the cup body.
