IML (IN MOULD LABELLING)



The name “In mould labelling” derives directly from its technique: a preprinted polypropylene label (PP) is placed in a mold in the form of the final product, such as in the form of an ink pack.
Then, the molten PP is added to the mold. It fuses with the label and, during curing, assumes the shape of the mold. Resulting in the fusion of the label and the packaging into one.

When starting an IML project it is important to inform not only the suppliers of the label about the ultimate goal of the project, but also the other partners involved, such as the partners of processing machines, molds and automation. Sharing production parameters with all partners helps you make every IML project a success!


THE PRODUCTION PROCESSES:

- Injection molding

- Blow molding

- Thermoforming



MOLD LABELING OFFERS MULTIPLE SIGNIFICANT ADVANTAGES:


- Maximum print quality

The offset printing technique ensures high resolution images. In addition, you can decorate all sides of a package with a single label.

- Strong and hygienic

The mold label resists moisture and major temperature changes: the best solution for decorating plastic packaging for frozen and fresh produce! The label on mold is also scratch-resistant, does not break and is not susceptible to wrinkles.

- Production period and costs

During the labeling process in the mold the cartons are produced and decorated in a single step. The storage of empty packaging becomes unnecessary, transport costs and storage belong to the past.

- Enviroment friend

The labeling on the mold preserves the environment: the packaging and the label consist of the same material and can be completely recycled.

- A wide range of appearance and touch options

The same plastic packaging product can be decorated with a wide range of different materials, paints and seals. This allows you to differentiate your product from the shelf.

- Rapid design changes

You only need to swap the design of one label for another in your IML automation to make a quick change. The loss in production is almost nil during the start of a new design.



VARIOUS IML SOLUTIONS AVAILABLE:

Glossy IML Labels

A glossy appearance is a great way to differentiate an IML package. A glossy label is based on an IML material with a single layer. Bright appearance is achieved as a result of processing in the IML system.

Manufacturers of packaging for confectionery and ink, among others, were the first adepts of the brilliant IML labels. Depending on the size of the plastic packaging, we offer a variety of material thickness options as well as different materials with various technical characteristics (such as fiber orientation and injection point sensitivity).

The glossy IML label is available for injection molding and blow molding. IML is being developed for thermoformed.


IML labels orange peel

Over the years, the orange peel - also known as satin - has become the best-known IML variety. This type of IML label is produced with a multilayer substrate, containing foamed polypropylene in the medium. Due to the use of high temperatures and pressure, some of the air is released from the substrate during the IML process. The result is an "orange peel".

There are a few reasons why this substrate remains the most popular:

- Efficiency in cost

- Ease of procedure

- The only IML label option that allows overlapping

- Does not make the package rounded (when used with packages <5 liters)



However, there are some technical features that should be taken into consideration when choosing the IML orange peel labels:

Choose the right thickness according to the dimensions of the packaging
Know how to create the perfect overlap
Experiment to both grain directions to optimize process parameters
Be aware of the sensitive area of ​​the injection site

The IML orange peel label is available for injection molding, blow molding and IML thermoforming. Typically, early-adopter markets such as ice creams, creams and margarine prefer the appearance and texture of the orange peel label.



Transparent IML Labels

In addition to the IML peel and bright orange labels, more and more markets use transparent IML labels. This option offers the possibility of creating a transparent surface in the package, keeping the colors vivid through the use of opaque white functionality.

Packaging manufacturers can offer these features with their production systems. However, some technical aspects should be taken into account:

- Direction of fibers

- Overlap Zone


The transparent IML label is available for injection molding and blow molding. IML is also available for thermoforming.
Markets such as cosmetics, hygiene products, sweets, ice cream and pet food are especially interested in transparent IML, since this option offers the "label" look.
