The use of adhesive tape in factories and factories increases the amount of plastic waste released into the environment, affecting the natural environment and people. However, with Nordson’s glue spray solution, which is currently being applied in most industries today, businesses do not need to worry about the problem of harming the environment. In addition, the glue spray solution from Nordson brings precision injection technology for hot melt glue or cold glue applied in many industries to help manufacturers: reduce costs, increase productivity and improve product quality as well as product appearance.
I. In which industry is the glue spray solution applied?
1. Industries:
Currently, the industries in general and products in particular applying glue sprayers are listed as: Food and beverage industry, pharmaceutical industry, packaging industry, wood industry, mattress industry, electronics industry, and industry. Automotive, Diaper industry, …
2. Nordson Company – the leader in glue spray solution technology:
Nordson is a world leader in providing solutions for the packaging and electronics industries. Nordson Glue Spray Systems are standard systems widely used in the global packaging industry. Manufacturing industries use this application as packaging for the food industry, labels for bottling applications, cans.
Nordson ‘s technology is used in the production of many everyday consumer products. As a leading supplier to the nonwovens industry, such as baby diapers, diaper pants, feminine hygiene products, surgical gowns, wipes and towels, Nordson equipment is Used in spray applications, applying adhesives, cosmetic primers or fragrance oils to these products.
II. Structure of Nordson glue spray system:
1. Glue machine – Melter:
The glue furnace is responsible for melting the glue to the set temperature before it is pumped out the glue pipe to the spray gun.
ProBlue® Flex Melter is the next generation of smart glue injection technology from the world’s leading manufacturer. Modular design solution that can be easily upgraded in the future gives users more flexibility, improved accuracy, better connectivity and easier system integration, etc.
Basic parts of glue melting machine – melter:
- Glue furnace – Glue Tank: Heating melts the glue in the tank by thermistor to the set temperature
- Pumping system: depending on the actual application, a piston pump or a suitable roaster will be used
- Pneumatic system: supply and adjust compressed air pressure for glue pump
- Circuit board and control screen system: signal processing and transmission
- I/O or Ethernet connection: advanced connectivity
- OLED display or OEM HMI
2. Glue conduit:
The glue pipe has the function of leading hot glue from the glue pot to the gun and heating to reach the set temperature, keeping the glue from degrading. The structure of the pipe consists of the core of the conduit and the outer layer of insulation, in the middle is a resistance wiring to heat the line and use a temperature sensor to send a signal to the glue sprayer.
The technology and material of the conduit determines the quality of the glue during use. High-tech glue pipes will limit the glue burning during the glue heating process in the tube. The less the glue burns, the less it will cause the glue to clog and stop the machine.
3. Pattern controller – Pattern controller
Controller – Pattern controller makes programming of spray adhesive profiles simple, accurate and reliable.
Nordson’s Spectra system is the next generation of controllers that reduce the complexity of programming injection profiles while improving product quality and increasing productivity.
In addition, there is also the feature of remembering the established profiles to save time for users.
4. Glue gun – Applicator/Gun:
This is the most important part in the glue injection system. Depending on the needs of each application, the company will tailor it to suit the intended use.
There are many types of glue spray such as line spray (Bead), point spray (Dot), spiral spray (Swirl), sweep (Slot), …
- The nozzle can be changed, for each purpose of use.
Glue line parameters can be customized such as glue length, glue line distance, finished product output, glue injection speed, etc.
5. Automatic gluing system
The Fulfill® Retrofit Adhesive Fill Kit is attached to the glue pot and automatically refills when the level sensor sends a signal. Automatic glue injection helps save labor, limit contact with chemicals and especially improve the efficiency of the glue spray system when limiting glue burning and protecting the pump.
III. Types of hot melt adhesives used in Nordson spray solutions:
Depending on the application and adhesive material, businesses will use different types of hot melt glue. Hot melt glue includes 4 main types: EVA, PO, PSA, PUR.
Hot melt glue is usually in a solid state, does not contain volatile organic compounds, is not affected by air humidity, this is convenient for the process of storing, preserving or transporting products, helping Save cost and labor a lot.
Hotmelt glue will have two main parameters:
- Adhesion: adhesive adhesion to the surface of the object.
- Cohesion: adhesion, bonding of the glue itself.

IV. Advantages of using Nordson glue spray solution:
1. Cost reduction compared to using tape:
The glue spray solution from Nordson helps the factory to use a small amount of hot melt glue on each product, which is much more cost-effective than using duct tape. The payback time for the glue spray system is only 1-2 years.
2. Stronger than using duct tape, avoid product loss:
Switch to a hot melt spray solution that improves stickiness and is more durable than duct tape. The use of glue spray also helps businesses easily check the integrity of the product packaging, easily identify if product loss occurs.
3. Make the product look more professional and aesthetic
Using glue spray helps the product look more aesthetic, the product also creates sympathy for consumers, increasing the likelihood of buying.
4. Environmental friendliness:
Using spray glue in production helps products not to slip when overlapping, easy to move, no need to use shrink film, making it environmentally friendly and cost-effective.
V. Advantages of using Nordson hot glue compared to conventional tape
| Nordson Hot Glue |
Regular duct tape |
|
Nice model |
|
| Hot melt adhesive will penetrate the surface of most cartons.
The glue is applied directly to the lids of the box, creating a solid bond that keeps the product square and solid. |
Ordinary adhesive tape does not penetrate the fibers on the surface of the carton and only helps to bind the two outer wings, making the inner wings loose, so the load capacity of the case will be weak, increasing the possibility of product damage. , which is costly during transportation |
|
Fake |
|
| Hot melt glue will cause the product packaging to tear if there is a case of trying to open the box before it reaches its destination. In addition, hot melt adhesive also helps to provide tamper proof and superior product protection. | Regular duct tape can be easily cut with a knife or any other sharp object. Products can be tampered with and product packaging closed without the consumer’s knowledge.
Regular duct tape also provides poorer tamper proof. |
|
Appearance |
|
| Hot melt glue is hidden under the wings of the product packaging. Helps products not to be hidden and clearly shows expensive logos and promotes the company’s brand image. | Conventional adhesive tapes lose or hide the company logo, limiting the effectiveness of the brand image and message. Regular tape is also more expensive and causes static electricity inside, which accumulates dust particles, which then adhere to the adhesive layer on the tape.
Retailers consider this as “dirt” on the inside of the product and return the product to the manufacturer |
