This is a hot melt adhesive film material that has appeared in the past two years and was born for products that require breathable properties. In fact, it uses hot melt adhesive film products as the base material and uses a perforation process to produce hot melt adhesive film products that are breathable and water-permeable.
Only the hot melt adhesive film with a backing paper can be punched, and the backing paper has a backing. They add an additional process to the conventional hot melt adhesive film production - drilling. Production process: First produce conventional hot melt adhesive film products, and then transport them to the punching factory for processing.
Judging from the several relatively mature hot melt adhesive film products currently on the market, hot melt adhesive films made of PA, PES, EVA, TPU, PO and other materials can all be drilled. The punching process has no restrictions on the width and thickness of the product. Note: The cost of perforated hot-melt adhesive films of the same specifications will be relatively higher, mainly because there are more processes.
Advantages: To make up for the air permeability and water permeability that conventional adhesive films do not have, the use of punched hot melt adhesive film lamination can maintain the original air permeability of the compounded materials. This is more important in specific areas, such as health belts, cushions, etc. At the same time, the stickiness remains strong.
Different types of hot melt adhesive films correspond to different properties and different bonding materials. But they can all be drilled, so before choosing to drill, you must first select the appropriate type and model of hot melt adhesive film.
