As a new form of label packaging, in-mold label has been popular in developed countries in Europe and America for many years. In recent years, it has also been favored by more and more printing substrate suppliers, label manufacturers and end consumers in China. In-mold labels are mostly used for trademarks and label descriptions of food packaging, and play an important role in food logistics, anti-counterfeiting, and identification. In-mold labeling is a new technology with great potential in China. Its promotion replaces labeling machines, reduces the production costs of manufacturers, and at the same time increases the recycling rate of food packaging (containers), reduces food inventory, and shortens The production cycle improves production efficiency and is very popular in the food and packaging industry.
The table is novel and beautiful
The in-mold label and the plastic container are formed together. The in-mold label and the bottle body naturally touch together, and the inlay is firm. The label changes with the shape of the powder bottle. The corners of the label are not visible on the plastic bottle, and the appearance looks very beautiful . The label deforms with the deformation of the powder bottle, so there will be no blistering or wrinkling. The hand feels smooth, especially for the daily chemical products with labels as the main outer packaging. The advantages are self-evident. The printing effect of the labels in the chess is good. It can print detailed design patterns and delicate pictures, with strong visual expression. , The in-mold label is tightly integrated with the bottle body. The label and the container have good drillability. The in-mold label has no corners, and the label will not be separated from the container when the container is warped and squeezed. Bid drop phenomenon. It can resist twisting, scratching and pollution during production and transportation, so that the label can remain intact and beautiful for a long time. The in-mold label will not bulge or mold in a humid environment.
Strong anti-counterfeiting function
The system of in-mold labeling is relatively complicated and requires special processing molds (in-mold labeling robots) or modification of the original mold. A set of molds is hundreds of thousands of yuan, and the production cost is high, which greatly reduces the possibility of fraud. Provide user manufacturers with a more reliable means of brand protection. However, only a few companies in China with large investment in disposable equipment can provide in-mold labeling services. There are many variations in mold design, label printing and processing, and labeling forming processes. Therefore, there are technical barriers to in-mold labels and it is difficult to counterfeit or imitate. In contrast, self-adhesive labels are very popular now. Mature technology is not only easy to counterfeit, but the cost is also very low. Therefore, counterfeit and inferior products of self-adhesive labels have harmed the interests of manufacturers.
Safety and environmental protection
Traditional labels wait until the container is formed before proceeding to the labeling process. The in-mold label and container forming can be completed at one time to avoid possible contamination of the bottle by the labeling process. The in-mold label and the bottle body are completely integrated. The in-mold label material usually uses the same material as the plastic bottle body. After the product is used, the plastic bottle can be crushed and recycled together, and the recycling rate is higher and the cost is low. In-mold labels are classified as environmentally friendly packaging materials, and plastic bottles with self-adhesive labels are more troublesome to recycle. You must first tear off the self-adhesive labels to remove the adhesive from the bottles and then recycle them. In contrast, recycling The efficiency is low and the cost of recovery is relatively high. Therefore, it can be said that the in-mold label conforms to the development trend of green packaging.
High efficiency and high benefit
In-mold label and container forming can be completed at one time, reducing labor costs, no need for post-processing, immediate delivery, reduced inventory, shortened production cycle, and improved production efficiency. In addition, it has good printing performance and can be used to print exquisite patterns in the same way as non-thousand glue labels.
market expectation
In-mold labels are used for the labels and instructions of plastic barrels, bottles, boxes, such as dairy products, ice cream, condiments, salad oil, soy sauce, vinegar, coffee, juice, tea beverages, yogurt, etc. that are frozen for a long time or contact with water. In addition, it is also used in plastic packaging such as HDPE, PP, PET, PS and other related industries such as medical treatment, machinery and agriculture. At present, in-mold labels are moving towards recyclable pre-labeled containers, which not only increase the speed of assembly line, reduce product costs, but also meet the needs of protecting the environment. Experts predict that with the rapid development of technology, in-mold labels will be Apply to various fields.
With the development of in-mold labeling technology, in-mold labels have been adopted in more and more fields. In addition to daily chemicals, lubricants, etc., they have also begun to be used in food and medicine. Also because of the wide range of applications, users have higher and higher requirements for in-mold label printing: how to improve the adhesion of the ink; the wear resistance of the varnish; the hot stamping adaptability and vacuum aluminum plating. Users have higher and higher requirements for molding, not only for the appearance of the molded container, but also for reducing costs and improving productivity. In order to meet different needs, a variety of new in-mold label materials have also emerged. In addition to the well-known white high-gloss PP in-mold label material from Japan’s YUPO, several new in-mold PP materials recently launched by the company are gradually being widely adopted by users.
The first is the transparent PP in-mold label. The transparent material can reflect the color of the container itself, so that the label and the container are harmoniously integrated, and truly achieve the "no label" effect. The transparent in-mold label not only solves the common curling problem of transparent PP and PE self-adhesive labels, but also reduces the cost for relatively expensive bottle screen printing. Moreover, it has a good printing effect and is also suitable for hot and cold hot stamping. Therefore, as soon as it was launched on the market, it has been widely used in the daily chemical industry that focuses on the appearance of containers.
