Blow Molding PP Toiletry Bottles with IML Label

Zhongyu Manufacturer created this Blow Molding PP Toiletry Bottles with IML Label, adjusting the formula for the multi-directional stretching characteristics of the irregular bottles. The film material is delivered in roll form or pre-cut sheet form. After injection molding, the film material integrates with the PP bottle body molecules, and the graphics are sealed in the bottle wall layer.

Parameter Table

IML Label Blow 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.molten plastic is blown into the mold, taking shap, the plastic wraps around the label along with the surface of the mold

5. As the plastic cools, the label integrates with the product, allowing the label to be directly embedded into the product

Manufacturing Process

1. Curved Surface Process Evaluation Stage

Receive the 3D drawings of the customer's bottles, analyze the stretching ratios of different areas around the bottle shoulder and handle edge, and output suggestions for film material and layout deformation adjustment.

2. Special Edition Color Printing Stage

Select food contact grade compatible inks, make color adjustment for the daily-use food production conditions, and strictly control the accuracy of multi-language small characters, QR codes, etc.

3. Dust-Free Composite Processing Stage

Complete the film material modification processing in the clean workshop, optimize the elongation rate of the film material, and adapt it to the different stretching deformations of the daily-use bottles at various locations.

4. Precise Die Cutting Process

Cut the film sheet according to the unfolded contour of the bottle body, strictly control the shape tolerance, and adapt to the automated mechanical hand picking and embedding label operation.

5. Simulation Injection Mold Verification

Use the corresponding bottle type molds to conduct on-machine simulation tests, check the actual state of text, QR codes, and patterns after formation, and screen out potential risks in advance.

6. Finished Product Inspection and Delivery

Conduct batch-by-batch inspection of the appearance and size of the film sheet, retain batch inspection records, and deliver the packaging to the customer after completion.

FAQ

Q1: How to improve the stretching deformation of the patterns around the handle of the shaped cosmetic bottle with a handle?

A: Based on the 3D data of the bottle, perform pre-compensation for the shape deformation and use special elongation rate film materials to reduce the pattern distortion.

Q2: Can we only purchase the roll material and have our side complete the die-cutting processing?

A: We support the supply of roll material and also provide reference for die-cutting tolerances.

Q3: Can this Blow Molding PP Toiletry Bottles with IML Label be used for food-contact edible oil and sauce bottles?

A: We can use a food-grade ink formula and provide corresponding material testing data.

Q4: Can the new IML film for cosmetic bottles be directly switched to the IML embossing process without modifying the original mold?

A: We need to evaluate the mold and embossing tooling, and confirm the feasibility of the modification.

Q5: What is the minimum order quantity for the IML film of this type of cosmetic bottle?

A: We support small rolls for sample testing, and the specific quantity will be calculated based on the bottle size.

Q6: Are the printing and film material post-processing processes outsourced for manufacturing?

A: All processes are completed in our dust-free workshop, and the batch production records are fully archived.

Q7: Are there any issues with the registration deviation of small-sized characters in multiple languages in different batches?

A: We strictly control the registration, and can stably control the printing deviation between batches.
