Packaging Hot Melt Adhesive
Packaging Hot Melt Adhesive Overview
Packaging hot melt adhesive is a heat-activated adhesive used to bond packaging components together during the industrial manufacturing process. The adhesive is heated to the recommended operating temperature and then applied to the object and then bonded to the second substrate during the open time of the adhesive. When it cools, the adhesive dries and forms a bond between the surfaces being joined.
Packaging hot melt adhesive is a combination of EVA and resin, primarily used for carton sealing. It cures quickly and flows easily, and can be used with a variety of standard hot-melt application systems.
Can be used on semi-automatic carton packaging machinery and fully automatic carton packaging machinery. It can also be used for the dispensing of the adhesive in stripes, where the adhesive is applied in a controlled pattern depending on the equipment and packaging process.

Packaging Hot Melt Adhesive Advantages
Fast Setting for Efficient Carton Sealing
Our packaging hot melt adhesive sets in 2-4 seconds for a more efficient way through the sealing process. It’s made for production environments where fast bonding and decreased waiting time are significant.
Non-Stringing for Cleaner Application
Our adhesive will not string and will help minimize unwanted adhesive strings and residue around the dispensing area. This facilitates cleaner carton sealing processes and aids reduce concerns about messy application.
Good Flowability for Smooth Dispensing
Our packaging hot melt adhesive has a Brookfield viscosity of 1,500 ± 400 cP at 160°C, which ensures good flowability for a smooth dispensing through compatible hot melt systems. This will aid in establishing a more controlled application process if the recommended operating conditions are adhered to.
Compatible with Standard Hot Melt Systems
We can supply all kinds of carton packaging machine with our adhesive, such as semi-automatic carton packaging machine, fully automatic carton packaging machine and normal stripe-coating dispensing system. The suggested speed for fully automatic case sealing lines is up to 30 products per minute, which can help customers evaluate the suitability of the lines prior to purchase.

Product Applications
This packaging hot melt adhesive is primarily intended for carton sealing and is suitable for semi-automatic and fully automatic carton packaging machinery.
Carton Sealing
The adhesive is ideal for sealing all kinds of cartons. Its short setting time supports carton sealing processes in which the bonded components need to proceed efficiently through subsequent production stages.
Actual suitability depends on carton construction, surface characteristics, adhesive application and the bonding requirements of the finished package.
Industrial Packaging Equipment
The adhesive can be applied using standard hot melt adhesive systems, including stripe-coating dispensing. It is compatible with semi-automatic and fully automatic carton packaging machinery, subject to the equipment’s operating requirements.
For fully automatic case sealing lines, the recommended operating speed is no more than 30 products per minute. The application pattern and operating settings should be verified on the intended production line.
Bonding Different Materials
In addition to carton sealing, the product’s technical data sheet lists bonding applications involving metal, non-metal, paperboard, laminated paper and non-laminated paper.
Compatibility may vary between individual material combinations. Where the adhesive is designed for a particular substrate or a combination of different materials, application testing is recommended to ensure that the desired bond performance is achieved prior to routine production use.
Application and Operating Recommendations
Application Equipment
This packaging hot melt adhesive is suitable for standard hot melt dispensing systems, including stripe-coating applications. Keep equipment at recommended temperature and provide a uniform adhesive pattern. Ensure that the nozzle, adhesive feed and temperature control are stable and operating correctly, regularly.
Recommended Operating Temperature
The recommended operating temperature is 160–180°C. Under extreme hot weather conditions, 140–150°C is recommended. Actual settings should be adjusted according to the equipment, substrate and working environment.
Production Speed
For fully automatic case sealing lines, the recommended speed is no more than 30 products per minute. Actual performance depends on the equipment, carton design and bonding conditions. Verify the settings before routine production.
Open Time and Setting Time
The open time of the adhesive is 5-8 seconds and the setting time is 2-4 seconds. These parameters affect the timing of carton joining and handling. Modify the application process based on the type of substrate, the amount of adhesive and production process.
The results may differ depending on the substrate, amount of application, temperature and production environments. Adjust settings as per equipment and material being processed.
