Hot melt adhesive is a new type of sealing material that appeared in the 60's. After 30 years of promotion, the hot melt adhesive sealing technology has developed into a very common type of carton sealing in the western developed countries. In China, when hot melt adhesive first appeared, it was difficult to popularize due to its high price. However, in recent years, the world famous hot melt adhesive manufacturers such as Atofindley and Fuller have already The construction of factories in Guangdong, China, respectively, reduced the cost, which made the prices of hot melt adhesives more reasonable and economical. This laid the foundation for the wide application of hot melt adhesives in China. At present, it has become more and more common in coastal areas, especially in foreign companies in Europe and the United States.
Second, the advantages of hot melt adhesive sealing Hot melt adhesive is a plastic adhesive, in a certain temperature range, its physical state changes with temperature changes, while the chemical properties remain unchanged, non-toxic and tasteless, can be used for food and medicine The industry is an environmentally friendly chemical product. Hot-melt adhesive bonding is the use of a hot melter to melt the hot-melt adhesive by heat. The glue after the adhesive becomes a liquid and is sent to the product through the throat of the fuser and the spray gun. The hot-melt adhesive is cooled and finished. Bonding, it can meet the requirements of the carton sealing, and overcome the previous defects in those carton sealing forms. Hot melt adhesive advantages:
1. Fast, the entire bonding process takes only 1-3 seconds to complete.
2. It occupies less space, and the hot melt machine is small in size and requires only a small space.
3. The lowest production cost per unit product.
4. The adhesive effect is good, the adhesive strength is high, and the overall strength of the bonded carton is strengthened, so that the carton is not easily deformed and cracked.
5. No treatment waste problem. Accord with environmental protection requirements, in line with export packaging requirements.
6. With anti-theft effect, it can be cited whether the package object has been opened by anyone.
7. Different glue spray modes can be adjusted for identification and anti-counterfeiting.
Third, the hot melt adhesive and the traditional sealing tape, packing tape in the carton sealing application comparison A hot melt adhesive and sealing tape in the carton sealing application stickers stickers (sealing tape)
Hot Melt Adhesive 1 has poor adhesive strength, low tensile strength, and can burn through the coating if the coated or oily paper board is weakly adhered. The adhesive strength is high. 2 It is easily creased and self-adhesive, resulting in shutdown. Wrinkle and self-adhesion problems 3 Tape needs to be replaced resulting in downtime of about 8-16% per shift. Adhesion does not cause downtime 4 Tape storage is valid for half a year and also requires certain storage conditions, otherwise it is easily deteriorated. Hot melt adhesive storage period is 2 years , And the storage area is small, no storage special requirements 5 Low performance in low temperature resistance, in the cold climate in the north, easy to open the low temperature resistance of the adhesive, as low as -40oC
6 The BOPP material used for packing tape is non-environmental product, which has environmental pollution and affects the export of the product. Hot melt adhesive is suitable for environmental protection requirements. There is no problem of waste disposal. The product is suitable for exporting to Europe and the United States. B hot melt adhesive and packing tape are used for carton sealing. Box Application Comparison Strapping Plastic Braid (Packing Belt)
Hot Melt Adhesive 1 Lifting the carton with packing straps during transportation can easily damage the surface of the carton. Hidden Adhesive Bonding will not damage or affect the beautiful carton printing. 2 The Cardboard Box is easily deformed or even cracked during transport. The strength of the carton is strengthened. It is not easily deformed and cracked. 3 The equipment needs to constantly adjust the tension of the tension band, change the belt without stopping for several times, and do not need to stop the feeding. 4 The commonly used packing belts are non-environmental products and wastes, which affect the export of products to European and American countries. Hot melt adhesives are suitable for environmental protection requirements. No processing waste problem, the product is suitable for exporting to Europe and the United States. 5 Packaging items are easily opened without verification. Can not verify that the packaged goods were opened without authorization. 4. Hot melt adhesives in carton sealing and packing tapes and U-shaped copper. The cost of nails is compared with the cost of hot melt adhesive strapping and sealing with nails. Each carton costs 0.05 yuan, 0.25 yuan, 0.06 yuan, and 0.15 yuan. * Calculated from the following data: Hot melt adhesive 25 yuan / kg (current market price)
2. Package with 8.3 yuan / kg 3. Sealing tape 20 yuan / 500 meters 4. Nail 12 yuan / 1000 five, hot melt adhesive and hot melt adhesive machine to play the advantages of hot melt adhesive in the carton sealing, must use high quality hot melt adhesive and the corresponding quality and reliable hot melt adhesive machine to be match.
For hot-melt adhesives, the original company Atofindicy and another multinational company, Bostik, have been merged. The complementary strengths make the newly formed merger company, Bostik. Findley has become one of the most powerful adhesive companies in the world and can supply all types of hot melt adhesives to meet the different needs of customers.
For hot-melt adhesives, the world-famous manufacturers of hot-melt adhesives, such as Nodson and ITW Dynatec, have representatives in mainland China. When choosing a hot melt machine, consider cost and efficiency. According to the speed requirements, the appearance and shape of the box, the production site, the layout of the characteristics of the appropriate choice of hot melt adhesive equipment and hoses, nozzles and supporting ancillary equipment to achieve automatic spray or semi-automatic spray, and then play the hot melt Advantages of plastic to achieve good results and economic benefits. In this regard, it is possible to consult a professional hot-melt adhesive machine manufacturer. Generally speaking, the use of a fully-automatic or semi-automatic adhesive injection method is more effective than the manual method in comparison with the manual method, which will give full play to the speed and cost advantages of hot-melt adhesives in terms of sealing.

Hot melt adhesive sealing technology overview
I. Overview For industrial enterprises, when the product is loaded into the carton, the next step will be to face the problem of sealing. At present, the vast majority of enterprises generally use traditional sealing tapes, U-shaped sealing nails, and strapping plastic braids. However, these sealing forms have more or less certain defects: if the sticky adhesive tape is not strong, it is not sticky to the coated or oily cardboard in particular. In addition, it is also prone to open gel in cold climate areas. Bundling plastic braids is costly and does not meet environmental requirements. U-type sealing nails can easily affect the surface quality of the product packaging, and it is easy to damage the products inside the box.
