Products Description
Our thin double sided PET film tape features an ultra-thin, dimensionally stable polyester backing coated on both sides with a high-performance acrylic adhesive matrix. Engineered for critical industrial bonding where standard filmic tapes fail under physical strain, this PET film tape delivers outstanding holding power and strong peel adhesion (≥15 N/25mm) on both high surface energy and low surface energy substrates. The rigid polyester carrier acts as a stabilizer during high-speed rotary slitting and precision press-stamping, preventing backing deformation and securing clean edge definition across automated packaging and electronics manufacturing lines.
Products Features
Exceptional 180° Peel and Shear Balance: Formulated to achieve an adhesion strength exceeding 15 N/25mm on stainless steel, ensuring immediate bonding integrity upon initial pressure application.
Elevated Thermal Tolerance: Sustains operational stability across thermal profiles ranging from 80°C long-term up to 150°C short-term peak exposures without adhesive mass degradation.
Superior Dimensional Stability: The high tensile strength PET carrier prevents longitudinal stretching during automated dispensing, maintaining strict tolerances on narrow-width rolls.
Versatile Material Compatibility: Establishes strong mechanical anchoring across HSE and LSE materials, including metals, glass, ABS, Polycarbonate, PP, PE, and PVC.
Die-Cutting and Converting Precision: High internal cohesive strength prevents adhesive stringing, bleeding, or edge oozing during complex die-cutting, kiss-cutting, and laser processing.
Chemical and Environmental Endurance: Resists degradation from humidity, UV radiation, industrial oils, and common solvents, locking component position over extended service lifespans.

Products Application
This double coated polyester tape serves as an essential structural fixing media across high-precision assembly lines where bond-line height must be strictly controlled:
Electronics and Optoelectronics Assemblies: Secure mounting of LCD reflective films, touch-screen lens surrounds, membrane switches, and battery pack insulating wrap layers.
Automotive Interior and Exterior Components: Bonding ABS plastic badges, decorative interior trims, side mirror heating elements, and cable harness positioning tags.
Plastic and Film Web Splicing: High-speed continuous flying splices for plastic films (PP, PE, PVC), paper webs, and commercial sign lamination.
Gasket and Component Attachment: Fixing thin metallic nameplates, rubber dampening pads, and shielding foams where thin double sided PET film tape eliminates profile bulking.
FAQ
Q1: How does the viscoelastic loss factor (tan δ) of this PET adhesive tape prevent bond degradation under continuous thermal-mechanical cycling?
A: Our acrylic adhesive matrix is engineered with a optimized viscoelastic loss factor to absorb high-frequency vibrational stress and thermal expansion differences between dissimilar substrates (such as aluminum to glass). Under cyclic temperature changes from 80°C to 150°C, the cross-linked polymer network prevents shear creep and interfacial micro-cleavage, locking the bond line without adhesive fatigue or edge lifting.
Q2: Will the 0.01 mm ultra-thin option of this PET adhesive tape suffer from adhesive squeeze-out during heavy nip-roller lamination?
A: No. The high internal cohesive strength of our cross-linked acrylic formulation, combined with strict coat-weight control, prevents lateral adhesive migration under high pressure. This preserves crisp perimeter edges and prevents roller contamination during continuous roll-to-roll lamination.
Q3: How does this double sided polyester tape maintain structural bond integrity when exposed to industrial cleaning agents or aliphatic hydrocarbon solvents?
A: The fully cross-linked solvent acrylic adhesive matrix provides exceptional chemical inertness against surface contact with aliphatic solvents, motor oils, and alcohol-based cleaning agents. The impermeable PET film carrier prevents liquid penetration into the adhesive interface, maintaining high static shear holding power without adhesive swelling or edge lifting.
