Substrate: PP polypropylene film (biaxially oriented BOPP) coated with pressure-sensitive adhesive (acrylic/rubber adhesive), which is the most common transparent sealing tape on the market.
✨Core Features
- Advantages: high tensile strength, good transparency, low cost, moisture and chemical resistance, not easy to break, can print logos as printing tape
- Disadvantages: The temperature resistance is average, and it is prone to softening when it exceeds 60 ℃ for a long time; Low temperature environment viscosity decreases; It's difficult to tear by hand and requires a knife/cutting machine
- Common thickness: film 23-32 μ m, total adhesive thickness 42-60 μ m; Common Width 42/45/48/60mm
Two major adhesive systems
- Acrylic adhesive (regular version): UV resistant, not easily aged, suitable for storage and sealing at room temperature; Low temperature viscosity is weak, and there is a loud tearing noise
- Natural rubber adhesive: stronger initial adhesion, good low-temperature performance; Afraid of direct sunlight and not suitable for long-term outdoor use, heavy box sealing is preferred
📌main purpose
- E-commerce cardboard box sealing and packaging (most mainstream), customizable printing tape available
- Temporary fixing and bundling of light industry
- Cable industry: Non adhesive PP isolation tape (only for isolation, without adhesive), cable core separation insulation identification
- Pipeline anti-corrosion: PP cold wrapped anti-corrosion tape (butyl rubber, buried pipeline anti-corrosion)
PP tape vs PET tape (industrial comparison)
| project |
PP (BOPP) tape |
PET Polyester tape |
| feel |
Slightly brittle, with a crisp sound when torn apart |
Slightly harder and more resilient |
| heat-resistant |
‑20～60℃，High temperature is prone to deformation |
‑40～120℃，Better temperature resistance |
| Price |
cheap |
relatively high |
| residual adhesive |
Ordinary style, easy to peel off adhesive residue |
Less residual glue, stable size |
| typical scenario |
Sealed packaging |
Electronic insulation, high temperature shielding, industrial fixation |
Attention: OPP tape commonly referred to as BOPP/PP tape is the same thing.
Usage Precautions
- Best operating temperature: 10-35 ℃, the surface should be dry and clean; Rubber rubber is preferred for low temperature environments
- Not suitable for long-term outdoor exposure and high temperature conditions, PET tape should be used instead in high temperature environments.
