In-mold labeling technology has been developed in Europe and America for many years. The application is very extensive. Since 2000, China's blow molding in-mold labeling technology has been vigorously promoted, and the in-mold labeling product packaging has produced good results once it is available. At present, there are several manufacturers of in-mold labeling technology and equipment in China to provide relevant equipment and corresponding technical services to plastic packaging products enterprises, to promote the development of in-mold labeling technology, and cause concern in the plastic packaging industry.
In-mold labeling systems are primarily used for blow molding products. The in-mold labeling technology is to use a special process to manufacture a trademark (in-mold label) by using an in-mold labeling machine to blow a plastic hollow product while blowing it into a mold cavity, and to perform labeling and high temperature and high pressure. Hollow product blowing is done simultaneously, which simplifies the production process compared to traditional self-adhesive labeling methods, which greatly increases productivity.
The advantage of the in-mold label is that the label and the plastic product are the same type of plastic resin, which can be fused together at a high temperature in the mold. The combination is natural, and has the characteristics of waterproof, oil proof, mildew proof, etc., and is not easy to fall off under various harsh environments. And the logo is more beautiful. In addition, labels and products can be recycled at the same time, simplifying the regeneration process and taking into account environmental protection, which is consistent with the environmental protection themes currently advocated at home and abroad. And because the in-mold labeling system (including the production of in-mold labels and the application of in-mold labeling machine) is relatively complicated, it also reduces the possibility of fraud, which leads to the pursuit of quality, the pursuit of quality, the pursuit of brand plastic packaging The user manufacturers of the products provide very reliable brand protection means. Therefore, the hollow packaging products produced by the in-mold labeling technology are more and more popular among users. In the domestic market, the in-mold label has been in the market for nearly a year or two, and finally began to scale the application, attracting more and more people in the industry and the attention of the end users of Zui.
In the past, blow molding machines equipped with imported in-mold labeling systems were 3 to 40% more expensive than ordinary blow molding machines. The price bottleneck has made the majority of users discouraged, and to a certain extent, has delayed the promotion speed of in-mold labeling technology. At present, after the hard work of engineers and technicians of relevant domestic equipment manufacturers, the company has finally developed its own in-mold labeling machine products, and its price is only about one-half to one-third of imported products. The product performance has reached And more than the same imported equipment, and has been successfully applied to production, resulting in great economic and social benefits.
At this stage, the application of in-mold labeling technology in China is still in its infancy. The blow molding machine equipped with in-mold labeling machine has a lower proportion of the users of the whole blow molding machine, but it has broad market demand and looks forward to the future. In-mold labeling technology will be promoted and applied in China.

Titration (also known as titrimetry[1] and volumetric analysis) is a common laboratory method of quantitative chemical analysis to determine the concentration of an identified analyte (a substance to be analyzed). A reagent, termed the titrant or Titrator,[2] is prepared as a standard solution of known concentration and volume. The titrant reacts with a solution of analyte (which may also be termed the titrand[3]) to determine the analyte's concentration. The volume of titrant that reacted with the analyte is termed the titration volume.
