How to reduce the drawing problem of packaging hot melt adhesive? The manufacturer’s downtime may come at a high cost. Preventing production issues and maintaining production line operation are crucial for brand owners. Threading is a common issue that affects consumer packaging. Reduce the drawing of hot melt packaging adhesive by making some easy to implement changes to three variables (equipment, environment, and adhesive).
Equipment: Check the settings every time the production line is changed
1. Check the position, angle, temperature, nozzle size, and condition
2. Confirm that the nozzle head is not blocked and in good condition
3. Check the distance between the nozzle and the substrate to determine if it can be reduced
4. Check the filter and hose to confirm that there is no accumulation or carbonization
5. Check the solenoid valve and fuel tank pressure
Environment: Environmental temperature and airflow can impactPackaging hot melt adhesive
1. Reduce direct airflow to avoid high viscosity and premature adhesive drying
2. Review the airflow in the production area to ensure that the fans and; HVAC The system will not directly blow towards the application point. This is more critical in applications where the distance between the nozzle and the package is large.
3. Substrate temperature is also a factor
Adhesive: Specific operating parameters are set by the formula
1. Check if the temperature of the hot melt tank is correct. If the hot melt adhesive is too sticky, the temperature may be too low
2. If the applicator and hose are not hot enough, please confirm to set the applicator temperature according to the recommended operating instructions, and then the adhesive will start to cool when moving from the can to the applicator
3. Confirm with the adhesive supplier that the correct adhesive has been used in the application. Some adhesives are easier to draw than others.
In our industry, it is crucial for EVA hot melt adhesive to handle packaging materials correctly – they must be removable and should not damage the finished product, production process, or environment during recycling. However, for adhesive companies, producing glue today is equally important, as it contributes to a more sustainable future for packaging and […]
Why can’t EVA hot melt adhesive stick? Hot melt adhesive is a widely used adhesive in industrial production processes, but there may be inevitable non stick situations during application. So what are the reasons that affect the viscosity of hot melt adhesive? It is mainly divided into the following three categories: 1 EVA hot melt […]
The core of Guangzhou flatbed hot melt adhesive isMoisture and heat resistance, good leveling, strong initial adhesion, and adaptable opening timePriority selectionModified EVA (mass production) or PUR (high-end)Accurately match according to the substrate, equipment, and season, avoiding “soft in summer and brittle in winter, opening glue in the south”. 1、 Guangzhou climate pain points (key […]
What is EVA hot melt adhesive made of and can they be recycled? The difference between biodegradable and biobased packaging follows a global trend where consumers want to produce and purchase more environmentally friendly products. The awareness and recognition of more environmentally friendly and sustainable packaging materials (such as reusable, biodegradable, etc.) are growing, but […]
