Hot melt adhesive film roll is a film made of hot melt adhesive material, usually supplied in roll form for easy storage and use. When heated to a certain temperature, the hot melt adhesive film will melt and become sticky, so that it can bond two material surfaces. After cooling, the film will re-solidify to form a strong bond. Looking for a roll of hot melt adhesive film? Welcome to contact Alster!
Basic Concept of Hot Melt Adhesive Film Roll
Hot melt adhesive film roll refers to a kind of adhesive film material that can produce adhesion after melting at a certain temperature. It is mainly made of hot melt adhesive and has the characteristics of fast bonding, solvent-free, and environmentally friendly. Roll of hot melt adhesive film is solid at room temperature and needs to be melted by heating before it can be bonded to the substrate. After heating, the film quickly cools and solidifies, thereby achieving a bonding effect.
Classification of Hot Melt Adhesive Film Rolls
Depending on the substrate and application, hot melt adhesive film rolls can be divided into many types, including but not limited to:
- EVA hot melt adhesive film rolls: Made of ethylene-vinyl acetate copolymer (EVA), it has good flexibility and bonding properties, suitable for textiles, footwear and other fields.
- PA hot melt adhesive film rolls: Made of polyamide (PA), it has excellent heat and chemical resistance, and is widely used in electronic components, automotive interiors and other fields.
- PES hot melt adhesive film rolls: Made of polyester (PES), it has high strength and wear resistance, suitable for clothing, household goods and other industries.
- TPU hot melt adhesive film rolls: Made of thermoplastic polyurethane (TPU), it has high elasticity and low temperature resistance, and is widely used in medical equipment, sports goods and other fields.
Characteristics of Hot Melt Adhesive Film Rolls
- Excellent bonding performance: After heating and melting, hot melt adhesive film rolls can quickly bond a variety of materials, such as textiles, plastics,etc., and have high bonding strength and are not easy to fall off.
- Easy to operate: When using the hot melt adhesive film roll, you only need to heat it up, without complicated equipment and processes. It is easy to operate, saves time and labor costs.
- Environmentally friendly and safe: The hot melt adhesive film roll does not contain solvents, does not emit volatile organic compounds (VOC), is environmentally friendly, and harmless to operators.
- Strong weather resistance: The hot melt adhesive film roll has good weather resistance and can maintain stable bonding performance in harsh environments such as high temperature, low temperature, and damp heat.
- Convenient storage: The hot melt adhesive film roll is solid at room temperature, easy to store and transport, and not easily affected by the environment and deteriorated.
Application of Hot Melt Adhesive Film Roll
- Electronic and electrical industry: used for bonding and fixing of electronic components, such as mobile phone screens, computer motherboards, etc., with good insulation and heat resistance.
- Textile and clothing industry: used for bonding of clothing accessories, such as linings, labels, badges, etc., easy to operate and strong bonding.
- Automobile manufacturing industry: used for bonding of automobile interior parts, such as seats, door panels, carpets, etc., with high temperature resistance and aging resistance.
- Furniture manufacturing industry: used for bonding of furniture panels, such as wood boards, plastic boards, etc., with high bonding strength, wear resistance and durability.
- Packaging industry: used for bonding of packaging materials, such as paper boxes, plastic bags, etc., with the characteristics of high efficiency and environmental protection.
How to Use Hot Melt Adhesive Film Rolls
The method of using hot melt adhesive film rolls is relatively simple, generally including the following steps:
- Preparation: Select the appropriate hot melt adhesive film roll according to your needs, and prepare heating equipment, such as hot air guns, hot presses, etc.
- Heating the adhesive film: Heat the hot melt adhesive film roll to its melting point temperature to make it completely melt, usually between 100℃-150℃.
- Bonding substrates: Apply the melted hot melt adhesive film roll evenly on the surface of the substrate to be bonded, and then quickly attach another substrate, apply appropriate pressure to make it fully bonded.
- Cooling and curing: After the bonding is completed, maintain the pressure and wait for the hot melt adhesive film roll to cool and solidify to form a strong bond.
Hot melt adhesive film with roll shapes are gradually replacing traditional adhesive materials and becoming the first choice for many industries due to their excellent bonding performance, simple operation, and environmentally friendly and safe characteristics. With the continuous advancement of technology, the application scope of hot melt adhesive film rolls will be wider and its market prospects will be broader. When selecting and using roll shapes of hot melt adhesive film, you should choose the appropriate type and specifications according to specific application requirements to achieve the best bonding effect.
