There are many types of adhesives, including hot melt adhesive, water-based adhesive, oil-based adhesive, etc. Different adhesive curing methods, speeds, times, and forms vary. What is the difference between hot melt adhesive and water-based adhesive for cardboard packaging?
1. Hot melt adhesive for cardboard packaging
Firstly, let’s talk about hot melt adhesive. Hot melt adhesive does not require solvents or water during operation. At normal temperature, hot melt adhesive is in a solid state; After hot melt adhesive is heated, it melts into a liquid state, and the liquid has the effect of adhesive force.
The advantages are: packaging and shipping costs are relatively low, and materials do not require freezing or drying equipment. It is easy to bond and has a relatively strong adhesive strength. High stability and good water resistance during storage.
The disadvantage is that it requires special application devices; Although the adhesive strength is high, it is easily affected by temperature and cannot be continuously heated.
2. Environmentally friendly water-based adhesive
Water based coating adhesives are emulsified using water as a solvent and require special emulsification equipment.
Advantages:It uses water as a solvent and is cheaper than hot melt adhesive.. Because it uses water as a solvent, it is very environmentally friendly. Under normal circumstances, it has no clusters and no odor. And the glue itself does not burn, with a wide range of solid content and viscosity, which can achieve good water resistance and adhesion.
Disadvantages:The disadvantages of water-based adhesive are that it takes longer to cure than hot melt adhesive, has lower adhesion, and is prone to freezing at low temperatures.. If metal vessels are connected, they are easily contaminated and can produce corrosive substances that corrode some of the metal.
The adhesive market is vast and the industry has unlimited development potential. As a result, numerous high-quality and cost-effective adhesive brands have emerged!
In fact, the difference between cardboard packaging hot melt adhesive and environmentally friendly water-based adhesive is not only these, but also their characteristics in construction. The construction characteristics of adhesives with different properties are also different. For example, hot melt adhesive can be applied, while water-based adhesive needs to be scraped and sprayed. Therefore, when choosing glue, it is also necessary to understand its construction process in order to prescribe the right medicine and ensure good adhesion.
In our industry, it is crucial for EVA hot melt adhesive to handle packaging materials correctly – they must be removable and should not damage the finished product, production process, or environment during recycling. However, for adhesive companies, producing glue today is equally important, as it contributes to a more sustainable future for packaging and […]
Hot melt adhesive granulesWhere is the cheapest wholesale? The question of ‘where is cheap’ is about channels, but the real question is’ where is the lowest overall cost ‘. There are roughly three types of wholesale channels: direct supply from manufacturers, distribution agents, and e-commerce platforms. Whether it is cheap or not depends on the […]
More and more manufacturers are using EVA hot melt adhesive to process books and other materials, regardless of the size of the processing plant, there will still be an upward trend in the future. This is because using this adhesive has the advantages of fast book publishing, short cycle time, beautiful appearance of books, and […]
Hot melt adhesive is a type of thermoplastic that melts into a solid state by heating and applying temperature. When the adhesive begins to solidify (heat loss) before the material is bonded, cold bonding occurs, which can lead to bonding failure. Usually, it appears to be firmly adhered after bonding, but the bonding strength may […]
