Why is hot melt adhesive used for food packaging?

Nowadays, the global promotion of environmental protection and health concepts is becoming increasingly widespread, as the emphasis on this aspect has rapidly led to higher environmental requirements for materials in various industries, including food packaging. At present, many factories pursue high efficiency, high speed, precision, and fully automated production. So the most important sealing step in the packaging industry is not only convenient and efficient to use, but also environmentally friendly products. Sealing the box only requires the use of a hot melt machine to melt the hot melt adhesive into liquid, which is then transported to the surface of the cardboard box through a spray gun or throat to cool and solidify. Therefore, hot melt adhesive sealing boxes have mostly replaced traditional tape and bundled packaging. The cost not only decreases but also becomes more attractive and of better quality. Can be used for food inner or outer packaging, cardboard box sealing, and beverage straws, what are its advantages?

  1. Good performance with multiple advantages
    Products such as cardboard boxes are inherently intended for packaging purposes, so transportation is essential. During transportation, it is necessary to upgrade the testing of cardboard boxes. Not only should it be able to withstand changes in environmental climate, temperature and humidity, but also the impact of loading and unloading processes. In the past, bundled and tape packaging was far inferior to current hot melt adhesive packaging. Firstly, the adhesive tape has poor viscosity and low tensile strength. Unstable adhesion with oily or coated cardboard can easily open; Bundled packaging is prone to displacement and is not tightly tied. On the other hand, hot melt adhesive quickly dries and has good penetration. After bonding with cardboard, it not only enhances strength but is also less prone to deformation and cracking, and can be applied to any part of the cardboard box.
  2. Cost
    The entire sealing and bonding process of hot melt adhesive only takes a few seconds, making it very suitable for mass production. Greatly improving efficiency and saving time, resulting in lower energy consumption and lower costs. Adding glue during processing will not cause downtime; Replacing the tape requires a lot of downtime and is quite troublesome. Moreover, there is no need for partitions inside the hot melt adhesive box. Compared to using adhesive tape to seal the box, the strength of the partitions inside is greater, which reduces the cost of partitions in this area.
  3. Appearance aesthetics
    At present, many businesses have high market competitiveness and require the appearance of cardboard boxes to be designed with patterns, conveying the product and company image to improve aesthetics. Therefore, it is necessary to minimize the factors that may cause obstacles to the appearance of cardboard boxes. Compared to hot melt adhesive, using tape may not be as aesthetically pleasing. Not only does it obstruct the pattern, but it also affects the information transmission outside the packaging. So using hot melt adhesive to bond the display space will be even larger.
