The biggest disadvantage of using this technique is that it is expensive when compared to hot lamination. Also, the chances of bubble formation are high during this technique. Where pharmaceutical manufacturing is concerned,
Hot Melt Glue offers quite a few advantages over conventional manufacturing techniques.
First of all, there are fewer steps required in the manufacturing of drugs and there are no drying steps, which saves time and increases productivity. The process is simple and can be carried out continuously and efficiently. Some specific applications for hot melt dispensing equipment are bag forming and sealing, tray forming, case and carton sealing, labeling, pallet stabilization, corrugated box assembly, folded cartons, and myriad types of product assembly.
The best part about using this technique is that it can be used for all documents. Paper that have inkjet ink and heat sensitive material can be easily laminated using this technique. It is a simple procedure and can be easily performed by people who have no formal training. Other advantages of using cold lamination machine are that they require little maintenance and are safe.
You know when you get a free gift with a magazine such as a CD or the free samples you get stuck to the inside pages? Nobody ever seems to be able to figure out exactly what that stuff is yet so many are strangely fascinated by it. It is in fact either glue dots or hot melt glue.
Another strange phenomenon to many people is what they put on envelopes and stamps to make them sticky when you lick them. Yes, you guessed it, this is quite frequently a hot melt adhesive. The reason why this is a common method that is used is because hot melt adhesives can be formulated to increase their water sensitivity, which is why they become sticky again when exposed to something wet.
As a result of the temperatures and intense mixing that occurs throughout the manufacturing process, active ingredients are more evenly dispersed in the polymer, this leads to a better bioavailability. So for those of you who thought
Hot Melt Web had no relevance to their lives whatsoever, you now know that you wouldn't get free samples in magazines without it.
