Material Features

White PET Insulation Tape — ≥5kV Dielectric Strength

Biaxially oriented white opaque PET film provides dielectric strength ≥ 5kV — delivering reliable electrical insulation for LED strip PCB assemblies, transformer components, motor windings, and electronic assemblies in demanding manufacturing environments. White opacity prevents light bleed-through in LED applications.

White Polyester Tape for Film Splicing — Dimensional Stability

Thiswhite polyester acrylic tape provides exceptional dimensional stability under the mechanical tension of high-speed roll-to-roll converting, flexographic printing, and laminating processes — ensuring flat, secure splices that run through printing presses and converting lines without splice-related downtime or web breaks.

White Polyester Masking Tape — 150°C Heat Resistance

Withstands continuous temperatures up to 150°C and short-term peaks up to 180°C — covering LED reflow soldering, powder coating oven cycles, and electronics assembly processes without adhesive migration or white PET film yellowing or deformation.

Solvent-Based Acrylic Adhesive — Long-Term Stability

Thispolyester tape uses solvent-based acrylic adhesive — offering superior aging resistance, chemical resistance, and moisture resistance versus rubber-based alternatives, with clean residue-free removal from film substrates, LED PCBs, and precision electronic components.

Clean & Stable Removal

Leaves zero adhesive residue after removal — critical for film splicing (where adhesive contamination affects downstream printing quality) and LED assembly (where residue on PCB contacts impacts electrical performance).

Applications of White Polyester Acrylic Tape

• White PET Tape for Film Splicing — Printing & Converting
  Used for roll splicing in flexographic printing, rotogravure printing, laminating, and film converting lines — the strong PET backing withstands converting line tension and the white surface provides visual confirmation of splice position during high-speed roll changeovers.
• LED Strip Insulation — Reflective White PET Backing
  Provides electrical insulation between LED strip PCB and aluminum channel/metal substrate — the white opaque surface maximizes light output by reflecting LED light forward, while ≥5kV dielectric strength prevents short circuits between strip contacts and metal mounting surfaces.
• High-Temperature Electrical Insulation — Transformer & Motor
  Provides reliable inter-layer insulation for transformer coils, motor windings, and capacitor assemblies — the white color enables easy visual inspection of winding layers during quality control in transformer and motor manufacturing.
• White Polyester Masking Tape — Electronics & Powder Coating
  Used for masking precision surfaces during powder coating, electroplating, and electronics assembly — the white surface provides clear visual confirmation of masked areas and enables on-tape marking or labeling during complex multi-zone masking operations.
• Precision Industrial Labeling & Surface Protection
  White PET backing provides a printable, writable surface for on-tape identification — used in medical device assembly, cleanroom manufacturing, and precision electronics where surface labeling and clean visual inspection are both required.

Q1 | What is white polyester acrylic tape used for?

White polyester acrylic tape is primarily used for film splicing in printing and converting lines, LED strip PCB insulation (leveraging the white PET film's high reflectivity), high-temperature electrical insulation, and masking applications up to 150°C. The white opaque backing provides unique advantages in LED assembly, visual inspection environments, and surface identification applications.

Q2 | Can white polyester tape be used for film splicing?

Yes. This white PET tape for film splicing provides the dimensional stability and adhesive strength required for roll splicing in flexographic printing, rotogravure printing, laminating, and film converting lines — the strong PET backing withstands converting line tension without lifting, and the white surface provides visual confirmation of splice position during high-speed roll changeovers.

Q3 | Is white PET tape suitable for LED strip insulation?

Yes. This white polyester tape is widely used for LED strip PCB insulation — the white opaque PET film reflects LED light forward (maximizing luminous efficiency), while ≥5kV dielectric strength prevents short circuits between the LED strip contacts and aluminum channel or metal mounting surfaces.

Q4 | What temperature can white polyester tape withstand?

Thiswhite PET insulation tape withstands continuous temperatures up to 150°C and short-term exposure up to 180°C — covering LED reflow soldering processes, converting line oven temperatures, and electronics assembly processes without adhesive migration or white PET film yellowing or deformation.

Q5 | Do you support OEM customization?

Yes. We offer full OEM services including custom width, thickness, color, die-cutting, and private label packaging with low MOQ.

Q6 | Are free samples available?

Yes. We provide free samples; express shipping cost is covered by the buyer.

Q7 | What payment methods are accepted?

We accept T/T, PayPal, and L/C.

Q8 | What is the MOQ?

Low MOQ — 1 piece accepted for sample testing. Contact us for bulk order pricing.

Q9 | How long does shipping take?

We ship via DHL, UPS, FedEx, or TNT. Delivery typically takes 5–8 business days worldwide.

Q10 | How is white polyester tape different from white paper masking tape or white PVC tape?

Unlike white paper masking tape (max 120°C, tears easily, solvent-sensitive) or white PVC tape (max 80°C, low tensile strength), this white polyester acrylic tape uses a biaxially oriented PET film backing — providing 150°C heat resistance, ≥5kV dielectric strength, superior tensile strength ≥120 N/25mm, and clean residue-free removal. It is engineered for demanding industrial environments — film converting, LED manufacturing, and electronics assembly — where paper and PVC tapes cannot perform.
