Technology and effect of in mold label (VI)

purpose of in mold label

the first generation of in mold label is based on paper, with heat sealing adhesive coated on one side and printed pattern on the other side. At present, most in mold labels are based on plastic film. During the blow molding process, the film does not need to be completely melted, but is integrated with the plastic container. The heat resistance, moisture resistance and chemical resistance stability are better than that of paper

in mold label has been popular in some European and American countries for many years, and the manufacturing and labeling process of in mold label is relatively mature. In Europe and the United States, the proportion of in mold labels used in container labels is about 12% ~ 15%. From 1984 to 2000 in North America, in mold labels maintained an astonishing growth rate of 20%. At present, blow molded finished products account for 95% of the in mold label production. In Europe, about 80% of the in mold labels are used in containers that are molded by injection molding process or thermal molding for daily food, such as soft bread, margarine, cheese, sauce and ice cream, and 20% are used in containers that are molded by blow molding for household chemicals, industrial washing products and some fruit juices

in the south of China, the in mold label market has developed in the daily chemical industry, mainly due to the requirements of anti-counterfeiting. In other developed countries, the daily chemical industry has always been the main goal of in mold label promotion. There are also examples of application in South China and East China, but the in mold label has not achieved good results in the field of daily chemical products in China. The reason may be that there are many domestic manufacturers of daily chemical products, the competition between them is very fierce, they are very sensitive to the cost, and the use of in mold labels requires huge investment, so everyone is in a wait-and-see attitude. In addition, the appearance requirements of domestic daily chemical products are uneven, and only a few high-end products are suitable for in mold labels (such as gravure printing, bronzing and other processes). Some other products have a considerable quantity, but their profits are relatively thin and their requirements for labels are relatively low. Therefore, there are many labels printed with paper-based self-adhesive or two-color silk. Although we have reached a consensus on in mold labels, manufacturers in the fields of molding, printing and so on have made quite negative investment in equipment, leading to the end-users in the field of daily chemicals can only take a wait-and-see attitude

food enterprises are the main application direction of in mold labels in terms of their quantity and types. In mold labels have great advantages in improving the value of commodities in terms of hygiene. However, it is still difficult to apply the in mold label to the food field in China, because the domestic food is mainly low-cost goods, and consumers' requirements for the appearance of food packaging are still behind the taste and price. Consumers and manufacturers still follow the consumption habits of the past. Iron cans and glass bottles are mainly used as packaging in food containers. Plastic containers, especially PP materials, which are widely used by in mold technology at present, are still very few. The application of in mold labels in food packaging is expected to come naturally after consumers' requirements for packaging are raised

however, China's in mold labels have entered a large-scale development in recent years, and the development speed is quite amazing (the base number is relatively small). Some well-known multinational companies have been using in mold labels on their foreign products for some time. Limited to the few domestic manufacturers with high-quality in mold labeling equipment and processes for blow molding and injection molding, the printing and processing of in mold labels is still immature. Therefore, the in mold label printing and processing market in China is only in the primary stage

it has only been twoorthree years since in mold labels appeared in China, and only a few enterprises have mastered the technology of in mold labels. In recent years, with the development of labeling technology, the price of label materials has decreased, and in mold labels have developed to a certain extent. In mold labels have begun to be favored by more and more insiders and end consumers

in mold label application example

1 Beijing Longmen hetiankuan Food Co., Ltd. is the first enterprise in the condiment industry to adopt in mold labels. Heat seal a layer of plastic film outside the 2.1l plastic barrel, and the inner layer of this film is PE. The outer layer is PP. During the blowing process of the plastic barrel, this layer of film is heat sealed on the barrel wall, so there is no need to label after filling rice vinegar. Compared with the old packaging, the new packaging has a clear and bright appearance; The production process is simplified, and the labeling link is reduced. The workload of the original day can be completed in two and a half hours, which improves the production efficiency; Moreover, one production line is reduced by one third of the staff (the original manual labeling workers). Although the cost per barrel increased by a dime, the total cost decreased. After using the in mold label, the labeling is more accurate than before, the transportation wear after filling is less, and the plastic label has more practical benefits than the paper label

2. PP plastic cup and PP plastic cover are mostly used for plastic boxed ice cream. Because ice cream needs to be refrigerated in the ice card giant, when the box is covered with water and frosted, the edge curling and bulging of the adhesive label caused by moisture occur from time to time. In serious cases, the label falls off, damaging the product appearance and image, and affecting the business, production and reputation. Therefore, famous enterprises in the food industry such as Beijing Nestle, heluxue and Baxi have successively adopted in mold labeling technology. Nestle (China) launched DSM's wangwenyong's 1.5L super large family ice cream in early 2003. The label is flat and firm, not easy to be stained by foreign matters, and the product packaging is more beautiful. The label reduces the injection raw material consumption of the box cover without the help of labor, reduces the labor input and improves the production efficiency. At present, Nestle has an annual consumption of 50000 in mold labels

3. Around 2000, in order to connect with the international advanced pharmaceutical packaging, Janssen head office of Belgium adopted the packaging form of in mold label bottle of Janssen Thailand branch. In addition, in mold labeling technology was just emerging in China at that time, and various suppliers (labels, printing, bottle blowing and other enterprises) recommended this new packaging form to users one after another. At the same time, in order to improve the product image, Xi'an Janssen timely adopted in mold labeling plastic bottles. Xi'an Janssen "Caile" medicine bottle is a 50ml in mold labeled polyethylene hydrocarbon bottle. The supplier is Fuxiang plastic packaging (Shanghai) Co., Ltd. and the label base material is Japan Yupo's in mold label. The product has a more beautiful appearance, enhanced the brand display effect, enhanced the anti-counterfeiting function of the metallographic microscope you use, avoided the possible pollution of the bottle caused by the labeling process, improved the work efficiency, and achieved sustained and stable growth in sales performance. After the packaging is changed, the in mold labeling bottle is changed from a cylindrical bottle to a flat round shape. The label is flatly attached to the front and back sides of the bottle body, and integrated with the bottle body, avoiding the phenomenon of edge warping and off label in the previous labeling, making the appearance of the bottle more beautiful and tidy, improving the brand image, and making it easier for consumers to read the instructions

around 2000, in mold labeling technology has just entered the Chinese packaging market. There are not many enterprises that can provide this packaging technology, the cost is high, and there are relatively few application enterprises. The anti-counterfeiting effect is very obvious

minimizing the pollution of packaging containers may always be the concern of all pharmaceutical enterprises. After Xi'an Janssen applied the in mold labeling bottle, due to the automatic operation of all machines, the pollution caused by the labeling process to the bottle was avoided to the greatest extent, and the work efficiency was improved. Most of the national standards for stainless steel materials stipulated the perfect combination of tensile test and hardness test at the same time

4. Xi'an kaimi is a household chemical enterprise with outstanding achievements in China. It always pays attention to the product packaging image and takes the route of medium and high-end washing products. At the end of 2003, we took the lead in applying in mold labels to several key products, such as 500ml kaimi Diwang, 350ml kaimi Lingjing and 350ml kaimi glass cleaner. This year, all cleaning product packages of kaimi have applied in mold labeling technology

5. Shanghai white cat household washing products have been at medium and low prices, and pay more attention to the product image. In early 2003, the in mold labeling technology was investigated. Although the cost of bottle making was more expensive than before, due to the saving of labor and manufacturing processes, the product cost was reduced to a certain extent, the production efficiency was also improved, and the shortcomings of label curling, easy glue opening and falling off were overcome. They decided to apply in mold labeling technology in a small batch in the near future

6. Foshan An'an has been using in mold labels since 2001, mainly considering the use of this technology in terms of anti-counterfeiting. In the past few years, the company has achieved unexpected results. In addition to anti-counterfeiting, it has also reduced costs

development of in mold labels

in mold labels are being applied to recyclable pre labeled containers, improving the speed of the packaging line, increasing container filling, improving the appearance and better extrusion performance. As countries begin to pay attention to environmental protection, after improving the process and reducing the production cost, the in mold label process is expected to be further developed in the next few years.
