Consumption survey of candy packaging

as the candy market is competing for taste in the candy market, it is increasingly chasing the white hot and seeking to become more popular. Consumers with high consumption are no longer able to pay. It is becoming more and more important just because the packaging is full. For candy enterprises, in order to improve and develop, they must provide consumers with more products with packaging charm and high packaging quality

on the eve of the Mid Autumn Festival and the national day, through the special inspection on the quality of candy packaging, it is found that today's candy packaging has indeed been greatly improved compared with previous years. However, there are still the following problems:

first, the packaging and printing coloring is not strong. During the inspection, it was found that some fruit candy wrappers were not well colored due to printing, and the paint on the wrappers was often stuck to the candy when they were peeled off, making them inedible

second, the wrapping paper is not wear-resistant. Some old people like to put a few sweets in their pockets. However, because the wrapping paper is not strong, the wrapping paper will be damaged and inedible after a short time. It is a pity

third, the date of production and shelf life are generally not indicated on the candy packaging. Because the candy package is too small, it is impossible to print the production date and shelf life. However, candy, like other foods, takes a long time, and various types of twists and turns of wire core are the important reasons for insulation eccentricity. 1. It is easy to soften, harden, taste and deteriorate, affecting food consumption, but this problem has not attracted the attention of more manufacturers

fourth, there is packet leakage. During the inspection, it was found that, except for some expensive candies such as chocolate, the missing package of common fruit candy and other candies is common, generally between 3% and 5%, and the missing package candies are often contaminated and inedible

although candy is small, it concerns millions of consumers. We hope that manufacturers will continue to improve the packaging quality so that consumers can buy candy at ease

Boda and Kangda jointly promote the development of solvent-free composite adhesives

under the trend of "low energy consumption and no pollution" and focusing on the development of green packaging, environmental protection and high efficiency will be the inevitable development trend of the packaging industry in the future. In terms of composite adhesives, it has become a consensus in the packaging industry that environmentally friendly and safe water-based and solvent-free adhesives will replace the traditional solvent-based adhesives. At present, in the United States, water-based adhesives have accounted for 30% of the flexible packaging composite adhesive market, while in Europe and Europe, solvent-free adhesives have accounted for 40% of the flexible packaging composite adhesive market. Waterborne polyurethane adhesive has the advantages of no pollution to the environment, non combustible, non-toxic, wide adaptability and so on. However, the composite strength of water-based adhesives is very low. 2. The data collection rate is too low to compare with that of ester soluble polyurethane adhesives. At present, the technical development in cooking is still a difficult problem. At the same time, the drying speed is slow, and the energy consumption and cost are high. Therefore, its application range in packaging is still very narrow. In a real sense, solvent-free polyvinyl chloride adhesive is an environmental friendly adhesive. At present, solvent-free adhesive has been widely used abroad. The utility model has the advantages of no solvent pollution and relatively low cost; No solvent evaporation drying process is required, which reduces energy consumption; The composite products are free from the problem of residual solvent and reduce the risk of fire in the production process. They are suitable for various types of plastic composite packaging and have good bonding effect on aluminum foil. They have high peel strength. Their chemical resistance and high temperature cooking resistance are comparable to those of ester soluble polyurethane

as an environment-friendly solvent-free two-component polyurethane adhesive, although it has been widely used abroad, it is far from spreading in China. The main reason is that the solvent-free adhesive has a high viscosity, and the existing dry laminating machines of most domestic composite film packaging manufacturers can not uniformly coat it, so the solvent-free special laminating equipment must be used, and the renewal of the equipment requires a lot of money and a long time

in addition, the solvent-free adhesive drying machine and solvent-free adhesive were all imported from abroad, with large equipment investment and high production cost. At the same time, due to the small scale, large number and fierce competition of Chinese flexible packaging enterprises, there are generally problems of uncertain business volume, which can not meet the needs of the operation of solvent-free composite production lines. As a result, the equipment of some manufacturers is often idle and the utilization rate of equipment is very low. However, with the successful development of domestic solventless coating and laminating equipment and solventless glue, the cost of using solventless laminating process in domestic enterprises will be greatly reduced. In particular, the (2006) No. 86 document issued by the General Administration of quality supervision, inspection and food inspection stipulates that products such as plastic packaging containers and tools for food must obtain a production license (i.e. QS certification) before they can enter the market, which puts forward stricter requirements for the hygiene and safety of food packaging enterprises. Driven by this environment, the development and application prospect of solvent-free composite process in domestic flexible packaging will be bright

as a science, industry and trade integrated enterprise that has been committed to developing and developing high-tech packaging and printing equipment for many years, Wenzhou Boda machinery has seen the market application prospect of solvent-free laminating equipment with a long-term vision. After years of research, it has successfully developed WTF solvent-free coating laminating machine recently. The main mechanical properties of the machine are as follows: 1. Glue coating and mixing mechanism: each unit glue is pumped into the special glue mixing mechanism through two groups of precision metering pumps a and B to achieve the solvent-free finished glue coating. 2. Solventless coating mechanism: in view of the irreversibility of solventless adhesive, it is designed into a glue tank and a five roll transfer coating mechanism. The required coating requirements are met through the adjustment of gap and speed. It is equipped with a PLC servo program control system. The coating mechanism can also be coated with UV curable organic silica gel. 3. UV lamp curing system: it can be equipped with high-efficiency UV lamp to cure according to the needs of the process. 4. Composite structure: according to the special process of solvent-free adhesive, the required finished products can be achieved through multi roll composite through tension and speed control. The effective working width of the coating equipment reaches 600 ~ 1600 mm, the maximum mechanical speed can reach 200 m/min, the maximum diameter of unwinding:

800mm, the maximum diameter of rewinding: 800mm, and the tension control range of the film: 2 ~ 45kg. The overall characteristics of the machine are: compact structure, less occupied space, low equipment installation and maintenance costs, and less energy consumption. According to the company's manager, the price of this solvent-free composite equipment is 2,3 lower than that of the same type of imported equipment. Therefore, it can greatly save the investment cost of enterprises

in order to further promote the solvent-free process, Boda machinery has formed a strategic alliance with Shanghai Kangda Chemical Co., Ltd., the first company in China that has successfully developed the solvent-free laminating adhesive, to jointly promote the two-component solvent-free polyurethane laminating adhesive that is conducive to the physical and mental health of workers and environmental protection, so that it can be widely used in the composite flexible packaging industry

Shanghai Kangda Chemical Co., Ltd., founded in 1988, is an enterprise specializing in the production of adhesives. Its founder, luqiting senior engineer, is a well-known scholar in the domestic adhesive industry and enjoys the government subsidy of the State Council. Under the leadership of President Lu, the enterprise has developed into a national leading enterprise of adhesives with fixed assets of 60million yuan and products of more than 200 types in eight categories with a starting capital of 25000 yuan. After years of painstaking research and development, the company has developed a series of two-component solventless polyurethane laminating adhesives with independent intellectual property rights

specific products include the following categories: W d8118 45oC coating adhesive, w d8128 normal temperature coating adhesive, w d8138 normal temperature coating high performance adhesive, and w d8168 cooking resistant adhesive. The basic characteristics of the rubber like materials of these experimental machines are: normal temperature coating, long operation time, small coating amount, high peel strength, curing at 40 ~ 50 OC for 48 hours or at room temperature for 7 ~ 10 days, and resistance to 100 ℃ boiling for more than 30min. It is suitable for laminating CPP, PE, PVDC, NY, OPP, pet and other films. In addition to the basic characteristics of the other three kinds of gum minerals, the cooking resistant gum also has the resistance to acid, salt and other media. It can be boiled at 121 ℃ for more than 40min. It is suitable for the composite between PA/CPP, pet, CPP and other transparent cooking films. Compared with the dry compounding process, these adhesives generally save 20% ~ 30% of the cost. The company's solvent-free adhesive has been used in the production of PVDC composite membrane of Shuanghui group, and the manufacturer has responded well

in China, the solvent-free compounding technology began to receive attention in recent five years. According to incomplete statistics, there are more than 30 solvent-free dry compounding machines in China, but they are all imported equipment. It is believed that with the localization of solvent-free composite equipment and materials, the solvent-free composite technology with more health, environmental protection, safety, energy conservation, efficiency and practical value will be recognized and used in the domestic upholstery industry. Broada and Kangda, who are full of foresight, jointly promote the development process of solvent-free composite process and create a more brilliant tomorrow for their own enterprises
