Mooncake gift box hardcover pasting hot melt adhesive granules case: How gift box factories can achieve stable production before the Mid Autumn Festival peak season

The problem of pasting in a mooncake gift box factory

Directly speaking, the result is that a boutique gift box factory in South China has switched to using Sunlife hot melt adhesive for pasting to adapt to the model, and the pasting process during the Mid Autumn Festival peak season has improvedThe repair rate for bubble curling has decreased from about 6% to within 1%, and the production line speed has increased by about 15%.Guangzhou Sunlife Trading has compiled this case for reference by peers who make high-end gift boxes such as mooncake boxes and tea boxes.

Problem site

During the pre peak season sampling, the customer found that the edge wrapping and inner lining pasting of the top and bottom covers were frequently bubbling and the corners were raised in the high-temperature workshop, especially at the joint between the laminated paper and the gray board. The opening time of the original adhesive was too short, and the workers had not yet compacted the adhesive before it dried, resulting in weak bonding; Heating up and rushing to finish has led to overflow and wire drawing, and the busier the work, the more chaotic it becomes.

Solution process

• Identify the bottleneck of the process firstThe judgment is that it is caused by a combination of insufficient opening time and fluctuations in adhesive temperature, rather than a paper material issue.
• Change the compatible modelUse gift box pasting type hot melt adhesive particles with slightly longer opening time and higher initial adhesion, allowing workers enough time to press them together.
• Standardized parametersFixed glue temperature range, glue amount, and pressure holding time, written as a workstation card.
• Send samples for testing before increasing the quantityAfter confirming that there are no bubbles during the small-scale trial run, the entire batch will be put into production to avoid overturning during peak season.

Frequently Asked Questions

Q: What should be considered the most when selecting adhesive for pasting and pasting high-end gift boxes?
Check the opening hours and initial adhesion. Pasting should leave enough time for pressing and be pressed firmly, so that the two match without foaming.

Q: What should I do if I’m afraid of running out of supplies during peak season?
Lock up the quantity in advance and keep stock in stock. Sunlife hot melt adhesive can assist customers in measuring usage and preparing inventory plans before the peak season.

Summary: The foaming and curling edges of gift box pasting are mostly due to the mismatch between opening time and temperature. By changing to the right model and standardizing parameters, stable production can still be achieved during peak seasons.
