This is a double-sided tape manufactured via Hot-melt Coating Technology.
Its structure can be broken down as follows:
Adhesive (EVA Adhesive): This is the core component. EVA stands for Ethylene-vinyl Acetate Copolymer. When heated, this material melts into a fluid that can be evenly applied to the substrate. Upon cooling, it rapidly solidifies into a viscous adhesive layer. EVA adhesive is characterized by excellent initial tack, fast curing speed, and cost-effectiveness.
Base Material (Cotton Paper): It refers to a highly durable, tear-resistant thin paper commonly known as kraft paper. Serving as the adhesive carrier, it provides the following properties:
Flexibility: Easily conforms to curved surfaces
Easy Tearability: Can be torn manually for convenient processing
Buffering: Has a certain filling effect on rough surfaces
Release Liner (Release Paper): Also known as silicone oil paper or anti-stick paper. Its surface is treated with silicone oil to prevent adhesive sticking. Its functions are as follows:
Protect the Adhesive Layer: Prevents the double-sided adhesive from sticking to itself or being contaminated with dust before use
Facilitate Rolling and Die-cutting: Enables easy processing during production
Thanks to its low cost, good initial adhesion, and excellent flexibility, it is widely used in the following scenarios:
Home Decoration: Frame and photo collage, wallpaper trimming, carpet installation, DIY crafts, etc.
Stationery and Gift Packaging: Photo album making, handicrafts, gift box packaging
Electronics Industry: Used for fixing and shielding non-precision parts with no heat resistance requirements, such as wire harnesses, lightweight speakers, and some plastic shells
Packaging and Printing: Carton sealing, internal product fixation in packaging boxes, and book binding reinforcement
Building Materials: Fixing skirting boards, mirrors, and lightweight insulation materials
Note: EVA adhesive has relatively poor temperature and solvent resistance (typically applicable in 0-50℃), making it unsuitable for high-temperature environments (e.g., near engine compartments) or harsh outdoor conditions requiring prolonged exposure to sunlight and rain.
What is the Material: Plastic, metal, wood, glass, or fabric? Different materials have varying surface energies, which will affect the bonding effect.
What is the Surface Condition: Smooth surfaces (e.g., glass, metal) or rough, porous surfaces (e.g., wood, cement)? Rough surfaces typically require thicker tape with better tack.
Temperature: Will it be exposed to extreme temperatures? EVA hot-melt adhesive has limited high-temperature resistance. For high-ambient-temperature scenarios, alternatives like VHB acrylic foam tape are recommended.
Humidity: Will it be used in humid or outdoor environments? EVA adhesive has lower water resistance and aging resistance compared with other adhesives.
Chemical Substances: Will it come into contact with solvents, oil, etc.?
Load: What weight or tension must it bear? Static load or dynamic vibration?
Adhesion Strength: Usually expressed in N/10mm or N/25mm; the higher the value, the stronger the adhesion.
Thickness: Total tape thickness, as well as the thickness of the substrate and adhesive layer. Thicker tape has better adhesion on irregular surfaces.
Holding Power: Measures the tape’s ability to resist continuous shear force by testing the time taken for sliding or displacement.
Initial Adhesion: The adhesive capacity of the tape upon initial contact, which is crucial for manual operation and positioning.
