Conclusion first: Factories with large daily shipments and automated production lines have lower comprehensive costs and better anti disassembly properties for sealing boxes with hot melt adhesive particles; For businesses that focus on small batches and manual packaging, adhesive tape is more flexible. The watershed is roughly 500 boxes per day – beyond this amount, the hot melt glue sealing machine can usually recover its investment within a year.
| Comparison item | Hot melt adhesive particle sealing box | Tape sealing box |
|---|---|---|
| Cost of single box consumables | About 0.03-0.06 yuan | About 0.08-0.15 yuan |
| Sealing speed | Production line automation, fast | Mainly manual, slow |
| Anti disassembly and anti-theft measures | Tearing open will damage the box and prevent tampering | Can be torn open and re pasted, with weak resistance to disassembly |
| Appearance | No tape marks, neat and beautiful | The winding marks are obvious |
| Environmental recycling | The cardboard box can be directly recycled | Need to tear off the tape before recycling |
| Initial investment | Sealing machine and adhesive glue equipment are required | almost zero |
In scenarios such as e-commerce warehouses, food factories, and daily chemical factories where thousands of boxes are shipped per day, hot melt glue sealing frees up manual labor from the packaging process, and the overall cost per box is only about half of that of adhesive tape; Export boxes and high-value goods place greater emphasis on tamper proof properties, and adhesive seals must leave marks when torn open. Sunlife’s hot melt adhesive for box sealing has fast initial adhesion and low temperature non brittleness. It is compatible with mainstream box sealing machines and can be used immediately. Guangzhou Sunlife Trading also provides on-site glue testing services.
Q: Will the hot melt adhesive seal open in winter?
Choose a low-temperature resistant formula and ensure 3-5 seconds of compression, and there are no problems with conventional warehousing logistics outside of cold storage.
Q: Can the old sealing machine be replaced with hot melt adhesive sealing?
Most folding and sealing machines can be equipped with a hot melt adhesive spraying system, and the cost of modification is much lower than that of replacing the entire machine. You can send a sample of the box for evaluation first.
In one sentence: For small quantities, use adhesive tape to save time, for large quantities, use rubber particles to calculate the total amount. Making decisions based on daily shipment volume is the least likely to be wrong.
