Technology has been changed and improved in many areas, and the packaging industry is not an exception. IML or In-Mould Labeling is the latest inclusion in packaging that combines products and label together to make them one. Other labels are generally attached against a completed container. But like its name, IML is placed in the process of mold and thus, it becomes a unified part of the packaging where you cannot separate label from the container.Here, you can get the information about IML opens an ocean of opportunities in packaging and labeling
In this post, we will discuss in detail about different manufacturing processes of IML products, the benefits it provides, and its usage in different areas of packaging. To know more about IML, keep scrolling.
Different manufacturing processes of IML:
Through the systematic procedure of blow molding, hollow plastic parts are produced. The process of blow molding is done by extrusion, injection, or stretching. In this process, first, the plastics are melted and shaped like a ‘parison’. The shape of a ‘parison’ is like a tube with an opening on one side so that compressed air can propagate within it to give it the desired shape.
In this molding process, manufacturers inject melt materials within a mold. Generally, thermoplastic or thermosetting polymers are used in this process. In this process, manufacturers inject a certain amount of hot melted mass within a mold under a high-pressure environment. With time, the liquid mass loses heat, gets cold and rigid, and adapts the shape of the mold.
The process of thermoforming is mainly used in case of solid and inflexible plastic packaging. Here, a thermoplastic sheet is heated first and manufacturers give it a certain look or shape. With time, when it gets cooled off and rigid, it maintains the shape. One easy and simple version of thermoforming is vacuum forming.
Benefits of IML:
While IML products serve many benefits, some of them are listed below:
i) It gives a product its desired look. Earlier, labeling was done on a certain portion of a cover. With IML products, you can label anywhere in your cover, giving it a proper decorative design.
ii) It provides the utmost printing quality. Through offset printing system, you can add high-resolution images and with one label, you can cover all portions of a container.
iii) IML packaging can oppose high and rapid temperature difference and humidity. So, it is a very good option for frozen product packaging. Moreover, they are scratch proof and you cannot crack or break it.
iv) IML products do not harm the environment. Materials used at the time of packaging and labeling can be totally recycled.
v) IML products are microwave and dishwasher friendly and pose no harm to food contact.
Usage of IML products:
IML products are extensively used in the packing of Fast Moving Consumer Goods (FMCG) products. It is used in making plastic bottles, use and throw shake glasses, stationery equipment, etc. It is also used in the packaging of frozen and refrigerated foods because of its high-temperature durability.
