In-mold label (IML for short) refers to a kind of label, which means that the previously printed and die-cut label is placed in an open mold, and the label and the resin are fused into a whole during the process of molding the plastic product.
In recent years, the use of in-mold labels has become increasingly widespread: it is used in food packaging containers, such as dairy products, ice cream, condiments; there are containers for petrochemical products, such as lubricants; there are containers for daily chemical products, such as shampoo, shower gel Etc.; as well as for washing containers such as laundry detergents, softeners, toilet cleaners, glass cleaners, etc.
The in-mold label has excellent performance in terms of appearance, production efficiency, anti-counterfeit, waterproof, anti-shedding, etc. This has also become the main reason why the merchants have adopted such a process.
Compared with traditional labeling methods, in-mold labeling methods have the advantages of improving production efficiency, reducing downstream equipment and reducing labor. Since the in-mold labeling and the container molding are completed at the same time, the label and the container are integrated after molding, and the complexity of the in-mold labeling molding process is also correspondingly increased. If the molding process of the in-mold labeling process cannot proceed smoothly and stably, the molding plant cannot only increase the production efficiency, but also increase the production cost.
The large part of the reason for using the in-mold label to increase the cost is that when the molding plant begins to quantify the production of a product, the product's non-defective rate significantly increases when compared with the small-scale trial production. The main reasons for the increase in non-performing rates are: 1. Bubbles: 2. Defective mark 3. Weight mark. 4, after the formation of the label off the ink and so on. Whether or not these problems can be solved is the key to reducing costs.
The above problems can be eliminated by changing the production conditions of the molding process and reducing the production speed. On the other hand, it is related to the size and shape of the container label. Changing production conditions or speed increases production costs. So we hope that the molding process does not make too many changes or settings on the molding machine. In this way, the in-mold labeling container can achieve the effect of reducing costs. Therefore, how to choose different uses, different materials, different processes, different manufacturers of in-mold label paper. It can be used in a large number of normal production during the process of printing and forming in the front course, which is the key to reduce the cost of in-mold labeling containers. Below, we briefly discuss the importance of selecting different labels for the production of in-mold label containers.
At present, the commonly used substrates in the market generally include PP, A, PP/PE compound, PP and coating. There are also BOPP and paper substrates, which are still relatively small in the market. From the perspective of the characteristics of the substrate. PE is the softest. PPjPE Secondly, PP has the most stiffness. The above-mentioned materials, in addition to paper, have a certain waterproof, anti-oil, anti-acid and alkali properties. Different materials have a certain label
The price difference is due to the small percentage of the label in the container cost. The price difference of the label raw material itself does not significantly affect the cost of the container. Many molding factories understand the price of labels. They are generally accustomed to using materials for the first time. When considering the use of new materials for labels, it is easy to make a single comparison from the price point, which will affect the reasonable choice of label paper. Various in-mold labeling papers are unique, and they need to be considered in the selection of labels: 1. Container size (label area size), 2. Container shape, 3. Molding speed and adhesion: 4. The printing effect of the label and the requirement for the flatness of the label after molding.
