Determine whether the material used to make the box is the same as before, and whether the surface has been treated, such as copperplate paper, with completely different properties from the original one. The performance differences of hot melt adhesives for the same purpose in the market are not significant. It will be difficult to find suitable hot melt adhesive for cardboard boxes, and passive selection may increase production costs. If the bonding effect of the cardboard packaging is really poor, it is recommended to adjust the surface treatment process of the cardboard box.
Secondly, whether the temperature has changed significantly from the previous time, the external temperature will affect the curing speed of the hot melt adhesive. When the weather is cold, the curing speed will be shortened, and if the line speed cannot keep up, it will not stick firmly. There are several solutions:
Firstly, it is to improve the speed of the production line, so that the glue can complete the sealing operation with better adhesive performance; Secondly, increase the usage temperature of hot melt adhesive by 5-10 degrees Celsius to prolong the cooling time; 3. Replace the hot melt adhesive with one that dries less quickly in cold weather.Moreover, whether the quality of the cardboard box hot melt adhesive is consistent with before and how much the quality of the raw materials fluctuates have an impact on the quality of the hot melt adhesive products. If the manufacturer does not control it well, it will have a significant impact on performance. This is a matter of choosing a long-term cooperative hot melt adhesive supplier. It is important to choose a Sunlife hot melt adhesive manufacturer with research and development capabilities, rather than relying on a formula to constantly adjust the composition ratio. What happens in the application can fundamentally solve the problem.
Products that have been designed, perfected, manufactured, and inspected to ensure compliance with the highest standards. It’s time for packaging now. The last thing we want is a fragile container that will burst under harsh conditions such as storage, transportation, or shelving. After all, packaging is usually the first impression of a product on potential […]
Hot melt adhesive granules are a type of plastic adhesive. Within a certain temperature range, its physical state changes with temperature, while its chemical properties remain unchanged. It is non-toxic and odorless. It is an environmentally friendly chemical product. Easy to package, transport, and store, solvent-free, pollution-free, and non-toxic. Some hot melt adhesives may encounter […]
Direct answer: The back adhesive layer of wireless adhesive packaging for books and periodicals is usually controlled at 0.6-1.0mm, and the side adhesive is 0.2-0.4mm; the thickness of the adhesive dots/lines for corrugated cardboard box sealing is generally 0.3-0.8mm; the thinnest layer for color box pasting is 0.15-0.3mm.The thickness is not necessarily better, sufficient, uniform, […]
Adhesives are used almost everywhere in the manufacturing industry to keep things together. Having a reliable adhesive will make a difference when attempting to bond surfaces. Each type of adhesive has its unique characteristics, which may make one adhesive more suitable for your current application than others. Water based adhesive Commercial water-based adhesive, also known […]
