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.
Sealed boxHot melt adhesive granulesWhat should I do if I block the rubber hose? The sealing line is most afraid of rubber hose blockage: the dispensing speed may fluctuate, and even flow may be interrupted, resulting in poor sealing of the box. There are two common reasons for pipe blockage – incorrect glue temperature and […]
How much hot melt adhesive is needed to secure the binding machine? The thicker the adhesive layer, the better. The adhesive layer of the 10-12mm book core is about 0.4mm, and for books with a thickness of ≥ 20mm, it is about 0.8-1.0mm. There are missing pages and an excess adhesive knife on top.
Copperplate paper and coated paper may lose powder, causing the hot melt adhesive to hang on the surface and not stick firmly. First, check out the powder and milling back burrs, and then choose the special adhesive for 396/397 copperplate paper.
Why do the back glue pot and side glue pot have different temperatures? The functions of the back glue (spine glue) and side glue (cover and book core side adhesive) on the book binding line are different: the back glue needs to penetrate deeply and have high adhesive strength; The side glue needs to cure […]
