Advantages of Printing Labels Inside the Empty Margarine Tubs

Nowadays, companies use various packaging made of different materials to display products on shelves. Plastic packaging is one of the most commonly used types of packaging. Companies customize plastic packaging through various printing methods to maintain a leading position in the competition on shelves. Over the years, in-mold labeling (IML) printing has also been considered one of the most practical and attractive packaging customization methods.

More and more packaging uses in-mold labeling

"IML" is a combination of the initials of the term "in-mold labeling"; it is a labeling technology that more and more companies prefer to use. The labeling to be printed is embedded into the plastic packaging inside the injection mold. In-mold labeling is fundamentally different from other labeling technologies. Before the mold is closed, the in-mold label is placed into the mold through an in-mold labeling robot system. After the mold is closed, molten polypropylene is injected into the mold. The in-mold label melts and adheres to the outer wall of the produced plastic product. As a result of this process, the final product features high-quality printing.

The labels used in in-mold labeling technology are typically made of polypropylene (PP) and color-printed through offset printing. Since polypropylene is a high-temperature resistant material, it can remain intact in hot injection molds.

What are the advantages of using in-mold labeling for empty margarine tubs?

The most remarkable feature of the in-mold labeling process is that the surface is a hardened transparent film, the middle is a printed pattern layer, and the back is a plastic layer. Since the ink is sandwiched in the middle, the product is scratch-resistant and has good friction resistance, and the color can remain bright and not easy to fade for a long time.

The raw materials of in-mold labels (IML Labels) are the same as those of plastic products produced, making it easy for recycling. This is an environmentally friendly method. Using in-mold labeling labels for empty margarine boxes increases the wear resistance and heat resistance of plastic products. In-mold labeling labels enhance the waterproof properties of the plastic products they contain. Since in-mold labeling is a labeling method conducted simultaneously with injection molding, using in-mold labels for empty margarine boxes can save time and cost.

In-mold labeling labels made of polypropylene have a bright appearance and are eye-catching, which positively influences the sales of empty margarine tubs. In-mold labeling, with the help of the in-mold labeling robot system, can provide hygiene labeling without human contact. The packaging products of empty margarine tubs produced using in-mold labeling technology offer a variety of product design possibilities. The largest visual advertising and information area has an abundance of sector diversity, with a wide range of capacity options.
