There are many kinds of foams to become laminated in packaging applications. Custom packaging and Laminating machine together with the bonding queries about hot melts and hot melt equipment every day.
The range of foams and substrates they are laminated to require a number of form of hot melts and various kinds of hot melt systems to make use of these hot melts.
Some 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 should be applied at the higher temperature and laminated fast among others remain “Open” and may be assemble a long time after the applying.
Most customers consider the use of hot melt for bonding Fabric laminating machine because they products accelerate the production process. The conventional method of applying hot melts is at bead form and unfortunately from your stick gun oftentimes. Often the hot melt in bead from burns into the foam decreasing the laminated region 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 methods allow you to use a longer open time hot melts really quick to a temperature sensitive foams or Travel Head Cutting Machine and not impact the surface negatively. The more time open time simply gives you much more time to work alongside the adhesive because it is being applied in the thin pattern to foam.
All substrates ought to be evaluated with all the proposed hot melt and application strategy to insure that this adhesive and application system meet you production and quality requirements.
