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.
