Full name: Polyethylene terephthalate film, density 1.34g/cm ³
Temperature resistance: * * -60 ℃~120 ℃ * * Long term use, thermal shrinkage rate<1.3% (120 ℃/15min)
Physical properties: high tensile strength, puncture resistance, excellent airtightness, resistance to oil and weak acids, not heat sealed itself, requiring composite PE/aluminum foil/EVOH for heat sealing layer
Conventional thicknesses: 12 μ m, 16 μ m, 23 μ m, 36 μ m, 50 μ m (VIP vacuum bags are most commonly used with 23/36 μ m substrates
