IML(in mold labeling) for extrusion blow molding

IML is a very robust method for decorating consumer and industrial products. IML gives product manufacturers the ability to have multiple colours, graphic effects and/or textures when the part comes out the mould. It is a cost-effective alternative to pad printing, hot stamping, paint and laser etching. IML has many advantages over pressure-sensitive labels such as its ability to eliminate secondary operations and problems typically seen with an adhesive application. It offers a ‘no-label’ look and is more durable. Some of the technical advantages of IML include:

  • Complete decoration of the moulded part
  • Durability of graphics: Inks are protected by film in second surface constructions
  • Secondary operations associated with post-moulding decoration are eliminated
  • Abolition of need for recessed label areas
  • Multiple films and constructions available to meet customer requirements
  • Easier to produce multi-colour applications
  • Generally lower scrap rates
  • More durable and tamper-proof
  • Superior colour balancing
  • No area where dirt can collect
  • Unlimited colours available

IML In mould labelling offers several major advantages:

Maximum print quality
The offset printing technique ensures high-resolution images. Besides, you can decorate all the sides of a container with one single label.

Strong and hygienic
In mould labels resist humidity and big changes in temperature: the best solution to decorate plastic containers for frozen and refrigerated products! In mould labels are also scratch resistant, cannot crack and are not susceptible to wrinkles.

Shorter production time and lower production costs
During the in mould labeling process containers are produced and decorated in one single step. Storage of blank containers becomes unnecessary, storage and transport costs belong to the past.

In mould labelling saves the environment: the packaging and the label consist of the same material and can therefore be fully recycled.

Wide range of look & feel options
The same plastic packaging product can be decorated with a wide range of different materials, inks an lacquers. This allows you to differentiate your product on the shelf.

Quick design changeovers
It only takes a shift from one label design to another on your IML automation to make a quick changeover. There is almost no production loss during the start-up of a new design.

IML(in mold labeling) on extrusion blow molding

IML (in mold labeling) on productionWhat is IML? The term “in mould labelling” is directly derived from the technique: a preprinted polypropylene (PP) label is placed in a mould. This mould has the shape of the end product, e.g. the shape of a butter tub.

Then the molten PP is added to the mould. It fuses with the label, and while curing, takes the shape of the mould. Result: label and packaging become one.

In mould labelling can be done in the following production processes:

  • Injection moulding
  • Blow moulding
  • Thermoforming

When starting up an IML project it is important to not only inform the label suppliers about the final objective of the project, but also the other partners that are involved, such as the process machine, mould and automation partners. Exchanging the production parameters between all partners helps you to make each IML project a success!
