Thickness of the bopp packing tape
1. Basic unit
BOPP tape thickness is marked in micron (μm),1 mm = 1000 μm.
2. Most common daily standard
40μm–45μm: Light duty → Small parcel, daily household sealing, light carton
48μm: Standard general duty → Regular express parcel, ordinary carton (most used by courier/shop)
50μm–55μm: Heavy duty → Thick carton, heavy goods, long-distance shipping, easy to not break or burst
60μm+: Super heavy duty → Industrial packing, export cargo, overweight large cartons
3. Simple analogy
Thinner tape = thinner paper, easy to tear by hand, only for light small boxes
Standard 48μm = normal bank receipt paper thickness, balanced toughness & cost, daily shipping perfect
Thicker 55μm+ = thicker notebook cover paper, strong tensile, not easy to snap, hold heavy packages tight
4. So in one words
The higher the micron number, the thicker, tougher and harder to break the BOPP tape; lower micron is thinner, cheaper, only for light simple packing.
Industry real shipping standard, per roll regular width 48mm/50mm BOPP tape, one layer sealing carton:
| BOPP Thickness | Suitable Max Carton Weight |
| 40 μm | ≤ 5 kg |
| 45 μm | 5 – 8 kg |
| 48 μm | 8 – 12 kg |
| 50 μm | 12 – 15 kg |
| 55 μm | 15 – 25 kg |
| 60 μm+ | 25 kg + Heavy industrial goods |
1. Width base: 48mm / 50mm standard width
2. If use double-layer sealing, can hold 30%–50% heavier
3. Long-distance / export shipping: choose one level thicker than actual weight
4. Cold weather: tape brittle, also upgrade 1 thickness grade
