There are numerous types of foams to get laminated in packaging applications. Custom packaging and Laminating machine using the bonding queries about hot melts and hot melt equipment daily.
The plethora of foams and substrates they can be laminated to require many different sort of hot melts and several types of hot melt systems to make use of these hot melts.
A number of the standard hot melts used are pressure sensitives (PSA) , polyolefins (APAO), ethyl vynil acetates (EVA). Each hot melt offers different bond capabilities. Each hot melt has different viscosities and softening points for temperature resistance requiring different application methods. Some have to be applied in a higher temperature and laminated fast as well as others remain “Open” and may be assemble a long time after the application form.
Most customers consider the usage of hot melt for bonding Hot met pur laminating machine because they products accelerate the production process. The conventional means of applying hot melts is within bead form and unfortunately from the stick gun in many cases. Frequently the hot melt in bead from burns to the foam decreasing the laminated part of 03dexopky involving the two substrates.
Optional ways of hot melt application which are used worldwide by foam fabricators are spray, swirl, fiberization and rollcoating. These techniques allow you to apply a longer open time hot melts very fast into a temperature sensitive foams or Swing Arm Cutting Machine rather than modify the surface negatively. The more time open time simply gives you additional time to do business with the adhesive as it is being applied in the thin pattern to foam.
All substrates must be evaluated using the proposed hot melt and application approach to insure how the adhesive and application system meet you production and quality requirements.
