How to choose and use hot melt adhesive particles for packaging and sealing in dust-free workshops? A manual for operation

The dust-free workshop (food, electronics, medical equipment packaging) is sealed with hot melt adhesive particles, and the core is three words: low smoke, low odor, and less dust. Prioritize the selection of low odor and low volatility rubber particles, and control the temperature, clean the pot frequently, and add glue in a standardized manner during operation to ensure stable sealing in a clean environment without affecting the cleanliness level. Below, we will explain the selection and operation in two parts.

Key selection points

• Low odor and low volatilityChoose a specialized low smoke and low odor formula to reduce VOCs and odors, and avoid affecting the air quality of the clean room;
• Suitable softening pointSelect according to the packaging, storage, and transportation temperature, and equip the food cold chain with a low-temperature resistant type;
• Clean without falling debrisThe appearance of the adhesive particles is clean and dust-free, reducing particle scattering during adhesive application;
• Compatibility certificationFood and medical packaging should prioritize models with corresponding safety certifications.

Operating Steps

• The first step is environmental preparationThe glue melting equipment should be placed at the sealing station with relatively low cleanliness requirements, and the glue adding area should be locally dust-proof;
• Step 2 Temperature SettingSet according to the recommended values of Sunlife hot melt adhesive (commonly 150-170 ℃ for sealing) to avoid overheating and smoke generation;
• Step 3: Standardize the addition of glueAdd glue with a clean measuring tool to avoid impurities and dust from being carried in by hand;
• The fourth step is to make up for it with a small amount of diligenceKeep the glue in the pot fresh and reduce the odor caused by long-term high-temperature oxidation;
• Step 5: Regularly clean the potClean the pot weekly to remove black residue and ensure that the glue line is clean and free of carbide particles.

Details of Three Cleanrooms

One is to choose an independent and sealed glue box as much as possible to reduce the exposure of the glue; The second is precise control of the amount of glue sprayed to avoid product contamination caused by overflowing glue droplets; Thirdly, the replacement of glue and cleaning of the pot should be arranged during the shutdown period and cleaned properly. Guangzhou Sunlife Trading can recommend low smoke and low odor models for clean room customers and provide safety information.

Frequently Asked Questions

Q: Can ordinary sealing rubber particles be used in the dust-free workshop?
It can be used for short-term emergencies, but ordinary rubber particles have high smoke and odor. For long-term use, it is recommended to switch to a low smoke and low odor specialized type, which is more in line with cleanliness management.

Q: Are there any additional requirements for rubber granules in food packaging sealing?
have Select models that meet food contact safety requirements and keep safety information for future reference. Sunlife hot melt adhesive can provide corresponding certified models.

Implement the selection of “low smoke and low odor” and the operation of “temperature controlled and diligent cleaning pot” in place, and the sealing of the dust-free workshop box is both firm and does not affect the cleanliness index.
