When using double-sided adhesive coating (with one adhesive line on each side of the box cover) for sealing express cardboard boxes, different box types, cardboard weights, and sealing speeds have an impacthot melt adhesive pelletsThe dosage has a significant impact. Rework with less explosive boxes and waste costs with more. This list summarizes the measured usage benchmarks for 5 common box types.
| box-type | Cardboard weight | Single sided adhesive line length | Total usage on both sides | Sealing speed |
|---|---|---|---|---|
| Standard docking box | 300g | 40cm | 2.0-2.5g | 15 boxes per minute |
| Heavy duty corrugated box | 450g | 45cm | 3.5-4.0g | 10 boxes/minute |
| Alien folding box | 350g | 50cm | 3.0-3.5g | 12 boxes/minute |
| Small self-locking box | 250g | 25cm | 1.2-1.5g | 20 boxes/minute |
| High stacking box | 500g | 50cm | 4.5-5.0g | 8 boxes/minute |
The fast curing series of Sunlife hot melt adhesive particles has a clear and precise adhesive breakage, suitable for high-speed sealing lines to reduce single box costs.
Q: Will the container burst after reducing the usage?
A: According to the standard usage in this list, the stacking pressure resistance requirements can be met. There is a risk of container bursting only when the usage is more than 10% below the benchmark.
Q: How much more double-sided adhesive is used than single-sided adhesive?
A: About 60-80% more. But the adhesive strength of double-sided tape is more than 1.5 times that of single-sided tape, and heavy-duty boxes must use double-sided tape.
The significance of surface treatment to the bonding strength of hot melt adhesives: The quality of surface treatment is often the key to determining the success or failure of a good adhesive joint. This is because the wettability of the adhesive to the surface of the adherend and the intermolecular forces at the interface (i.e., […]
For a long time, assembly lines have been the most effective way to mass-produce almost all products. Of course, product assembly has been constantly improving. In recent decades, hot melt adhesives have become an indispensable part of the assembly process. Here are several ways in which hot melt adhesive is crucial to the success of […]
Round spine hardcoverhot melt adhesive pelletsSpecial requirements The spine of a round spine hardcover book is curved, and when opened, the book core bends along the curved surface. The adhesive layer needs to have good flexibility and resilience. Hard rubber particles have high adhesive strength but are prone to cracking when bent, while soft rubber […]
Not all cardboard boxes are standard rectangles The e-commerce and retail industries are increasingly using irregular cardboard boxes (such as hexagonal boxes, drawer boxes, and top and bottom covers), and the sealing and gluing path is much more complex than standard unboxing. Here are 5 common types of irregular box shapeshot melt adhesive pelletsGlue application […]
