Hot melt adhesive film
Different Types of Hot Melt Adhesive Films
There are many classification methods for hot melt adhesive films, including classification by ingredients, methods of use, properties, uses, bonding materials, and size specifications.
The hot-melt adhesive film is classified into TPU hot-melt adhesive film, PES hot-melt adhesive film, PO hot-melt adhesive film, EVA hot-melt adhesive film, and PA hot-melt adhesive film according to the classification of ingredients.
Different hot melt adhesive films differ in appearance, properties, and adhesion to different materials. For example, TPU hot melt adhesive film with medium and high-temperature melting points is more used for elastic bonding fabrics; EVA hot melt adhesive film is more used for yoga mats.
High-temperature TPU hot melt adhesive film has elasticity, transparent colour and excellent washing resistance. Mainly used in the bonding of elastic fabrics, it can be used in sports apparel, underwear, home textiles and other fields.
Its advantages are high viscosity, elasticity, washability and softness.
Main application bonding: cloth, polyurethane sponge, TPU film, ABS
The low-temperature TPU hot melt adhesive film has no elasticity, the colour is white and translucent, and it is washable. It is mainly used for the bonding of leather, polyurethane sponge, PVC film and other materials. The advantage is low-temperature bonding, which is not easy to cause thermal damage to the material.
Main application bonding: leather, polyurethane sponge, cloth, PVC film, wood, paper.
PES hot melt adhesive film has no elasticity, the melting point is medium and high temperature, the color is white and translucent, and it has excellent washing resistance. Mainly used for the bonding of polyester fabric, polyester sponge, PET film and other materials, and can be used in clothing trademarks, warning reflective strips, jacket fly, home textiles, industrial products and other fields. The advantages are a stiff hand, good tack and excellent washability.
Main application bonding: polyester fabric, polyester sponge, PET film, aluminium metal.
EVA hot melt adhesive film has elasticity, low-temperature melting point and transparent colour. It is mainly used for the bonding of EVA foam, XPE foam, PET film, PP non-woven fabric and elastic fabric. It can be used in shoe materials, home textiles, home building materials, clothing and other fields.
Compared with other films, EVA film has slightly worse adhesion and washing resistance on fabrics, so it is not used much in clothing. The advantages are low-temperature bonding, easy operation, elasticity and softness.
Main application bonding: EVA foam, XPE foam, paper and wood, PP non-woven fabric, PET film, elastic fabric.
PO hot melt adhesive film has no elasticity, high-temperature melting point, transparent colour, washable. It is mainly used for the bonding of materials such as cloth, sponge, iron sheets, etc., and can be used in clothing trademarks, industrial products and other fields.
The raw material cost of PO film is low, so the product price is cheaper. The advantages are that: cheap, and washable.
Main application bonding: cloth, sponge, iron sheet, steel sheet.
PA hot melt adhesive film has no elasticity, high-temperature melting point, transparent colour, washable. It is mainly used for the bonding of various fabrics, sponges, PI films, PET films, nylon and other materials. It has good chemical stability and better high-temperature resistance. It can be used in electronics, clothing, home textiles and other fields.
Due to the high price, in the field of clothing, most uses can be replaced by TPU film, so PA film is less used in clothing. The advantages are: suitable for all kinds of textiles, excellent viscosity, and higher temperature resistance.
Main application bonding: all kinds of fabrics, sponges, PI films, PET films.
What is hot melt adhesive film?
Hot melt adhesive film is not sticky at room temperature, similar to the ordinary film, but it melts at high temperature, is sticky on both sides, and does not contain solvent. It is an environmentally friendly adhesive with no allergic skin irritation.
The hot-melt adhesive film we produce is a thermoplastic hot-melt adhesive film material. Unlike the thermosetting hot-melt adhesive film, it can be melted and bonded many times, while the thermosetting hot-melt adhesive film can only be melted once. It can be seen that thermoplastic hot melt adhesive films are inferior in high-temperature resistance and are widely used in the bonding of textiles and fabrics and related fields, such as clothing, shoe materials, hat materials, automotive interiors, and home textiles.
Hot melt adhesive film has different names, such as plain film, thermal lamination film, heat activated adhesive film, iron on adhesive paper, thermal film bonding, and so on. As long as they are used for double-sided bonding, the products referred to are identical.
With and without backing paper:
There are three types of hot melt adhesive films: with release paper, PE release film, and without backing paper. Among them, the use of release paper and PE release film is the same. They are first attached to one side of the material, then peel off the backing paper, and then attach to the other side of the material (both times need to be heated). The hot melt adhesive film without backing paper only needs to be placed in the middle of the two materials, and then pressed on one of the materials to complete the lamination.
In the above hot melt adhesive film products with different components, there are instructions on whether the product has a backing paper, you can check it to get the information you want.
It should be noted that in the same type of hot-melt adhesive film, the hot-melt adhesive films with backing paper and without the backing paper of different models have similar compositions, but they are not exactly the same.
Adhesive film properties:
Different hot-melt adhesive films have different properties, including high/low-temperature use, elasticity, wash-resistant strength, softness, color, high temperature, and low-temperature resistance, etc. You can choose a suitable film according to your needs, which can be viewed in the TDS section of the product link above.
Field of use:
Different types of hot melt adhesive films have different application fields due to their own properties and materials suitable for bonding. For example, TPU high-temperature hot-melt adhesive film is more used in underwear because it has high elasticity and is more washable; PO hot-melt adhesive film is more used in trademarks because it is cheap and washable.
Applicable materials:
Different types of hot-melt adhesive films are used for different materials. For example, for bonding XPE foam, hot-melt adhesive films made of EVA are usually used because they are all made of EVA; hot-melt adhesives such as TPU are usually used for elastic bonding fabrics. Adhesive film, because it has elasticity; PES hot melt adhesive film is usually used for bonding PET film because it has better viscosity; low-temperature TPU film is more used for bonding leather because it will not damage the leather and can provide Good adhesive adhesion. Materials to be bonded are broadly classified into several types, including cloth, leather, sponge, film, wood, plastic, rubber, sheet metal, and more.
