Difference Between Hot Melt Adhesive Film and Web

Hot melt adhesive mesh and hot melt adhesive film are products made through different production processes. Want to know the difference between hot melt adhesive film and web? Follow us! Hot melt adhesive mesh is usually formed by applying hot melt adhesive on a mesh-like substrate to form a mesh with good air permeability, which is suitable for applications that require air permeability, such as clothing and medical patches. In contrast, hot melt adhesive film is formed by directly applying hot melt adhesive on the substrate to form a continuous adhesive film with higher viscosity and sealing, which is suitable for occasions that require strong adhesion and waterproofness. Due to different production processes, there are significant difference between hot melt adhesive film and web in terms of cost, air permeability and viscosity.

Difference Between Hot Melt Adhesive Film and Web

Difference Between The Production Process of Hot Melt Adhesive Film and Web

Hot melt adhesive web and adhesive film are both hot melt adhesive products, but the production process is different. Hot melt adhesive web is made by melting hot melt adhesive through an extruder and then using melt-blown web forming method. It looks similar to non-woven fabrics and is packaged in rolls. You can check hot melt adhesive web for more information; while hot melt adhesive film is made by melting hot melt adhesive through an extruder and then using a doctor blade, laminating machine or blow molding machine. It looks similar to a film and is packaged in rolls. You can check hot melt adhesive film for more information.

Difference Between the Cost of Hot Melt Adhesive Film and Web

The commonly used hot melt adhesive mesh film is much cheaper than the commonly used hot melt adhesive film. This is mainly because the commonly used hot melt adhesive mesh film has a low gram weight, mainly 15g/㎡-30g/㎡, while the commonly used hot melt adhesive film is usually 0.03mm, 0.05mm, 0.10mm thick, converted into a gram weight of generally 28g/㎡-120g/㎡, the glue content is much higher, so the price is also more expensive. Of course, if the gram weight of the hot melt adhesive mesh film and the hot melt adhesive film is similar, the cost is not much different. At the same time, some models of hot melt adhesive films are equipped with release paper, which will increase the additional cost of the film. Therefore, the most intuitive feeling for everyone is that the price of hot melt adhesive film is more expensive.

Difference in Breathability Between Adhesive Film and Web

The structure of hot melt adhesive mesh determines that it is a product with good breathability. It can be used for fabric bonding in the clothing field, and it can still maintain the breathability of the fabric after bonding; while hot melt adhesive film has no breathability, so its production process is to make it directly into the shape of a thin film, which will block the mesh of the fabric after bonding.

Difference in Viscosity Between Hot Melt Adhesive Film and Web

Usually, hot melt adhesive film has better viscosity than hot melt adhesive mesh. This is not just a problem of high gram weight of hot melt adhesive film, because in the structure of hot melt adhesive film, the adhesive molecules are closely connected, while there will be a certain gap between the adhesive molecules of hot melt adhesive mesh. Therefore, even if the adhesive content of the adhesive mesh is the same, the adhesive film has greater viscosity than the mesh. Customers with higher fastness requirements can choose this type of product. Of course, there are many other factors for bonding strength, such as choosing a suitable type of adhesive film.

Differences in the Application Fields of Film and Web

Application Fields of Hot Melt Adhesive Film

Hot melt adhesive film is widely used in many fields, including labels and logos, packaging materials, electronics, clothing industry and automotive industry. It provides excellent adhesion and durability in label making, ensuring that labels can adhere firmly to various surfaces for a long time. As a packaging material, it can effectively seal and protect items from damage. In electronic products, hot melt adhesive film is used for insulation and protection, such as mobile phone screen protectors and circuit board insulation materials. In the clothing industry, it is used for heat transfer logos and patching fabrics, providing strong bonding while maintaining the softness of clothing. In the automotive industry, hot melt adhesive film is used to fix and bond interior parts, with high temperature resistance and durability, suitable for various in-vehicle applications.

Application Fields of Hot Melt Adhesive Web

Hot melt adhesive mesh film performs well in the fields of medical, textile, construction, home and filtration materials. It is often used in medical dressings such as wound dressings and breathable bandages. Its mesh structure allows wounds to breathe, accelerate healing while providing necessary protection. In the textile and clothing industry, it is used to make adhesive parts that need to be breathable, such as sportswear and breathable fabrics, to enhance wearing comfort. In the construction and home fields, hot melt adhesive mesh is used for wallpaper and floor paving to improve the blistering problem caused by moisture. In filter materials, its mesh structure helps to make air and liquid filters, providing good filtration effect and breathability. In the packaging industry, the breathability of the mesh makes it perform well in food and pharmaceutical packaging, preventing moisture from being generated and maintaining the freshness of the product.
