First of all, let’s talk about the results: a textbook printing factory in South China needs to complete wireless binding of about 1.2 million teaching aids 45 days before the start of the school season. After switching to Sunlife hot melt adhesive for books and magazines and locking in the batch supply plan, the production line continues to operate at full capacity, with a page drop rate controlled below 0.3%, and delivered on schedule.
This printing factory has a peak production of teaching aids in July and August every year, with three high-speed glue binding lines operating in two shifts. In previous years, there were two pain points: one was the tight supply of rubber granules during peak seasons, with temporary restocking waiting for a week and production lines having to stop waiting; The second issue is the fluctuation of glue temperature on the high-speed line, causing some batches of book backs to become brittle, and there have been feedback of page drops since the start of the school year.
| indicator | Last year’s peak season | This peak season |

| Stop the line and wait for glue | Accumulated for 3 days | 0 days |
| Page drop rate | About 1.2% | Less than 0.3% |
| delivery cycle | Delay by 5 days | 2 days in advance |
Q: What are the special requirements for adhesive particles in teaching aids?
Teaching auxiliary paper is lightweight and frequently flipped, requiring good adhesive strength and resistance to repeated folding. Ordinary sealing rubber particles cannot replace book and magazine specific particles.
Q: How to ensure continuous supply during peak season?
Confirming the schedule one month in advance and signing a batch supply plan, the manufacturer prepares production according to the plan, which is much more secure than placing an order temporarily.
The experience of this case is simple: during peak season, it’s not just about the quality of rubber particles, but also about the coordination of supply rhythm and on-site debugging.
