Technical Function of Hot Stamping Foil:

1) Temperature resistance: The temperature scope of golden and silver PET hot stamping film is -40-210, and the highest working temperature is 170
2) Waterlogging tolerance: It can be long preserved at the environment of 90% relative humidity.
3) The heat coefficient is 0.22-0.25w/m.k
4) Stability: Absorb 0.2-0.3% and shrink 0.7-0.8% in 24 hours
5) Radiativity: Good gamma radiation resistance and good UV-resistance
6) Incendivity: V₀ grade, fireresisting (L01) 46-47%
7) Physical function: Vitrification transfer temperature is 215, and the density is 1.27-1.4/cm³
8) Elasticity: The fracture tensile stretch is 59-60%, stretching intensity is 90-100Mpa, the rockwell hardness is 100-110, and the toughness is 50-60J/m
9) Covering (gold, silver) racking strength: (3-10) N/25mm
Specifications of Hot Stamping Film:
The thickness of gold and silver hot stamping foil is 18um-100um, the width is 15mm-1300mm, and the width can be cut arbitrarily according to customers' requirement. We manufacture gold and silver two kinds of hot stamping foil, it 
can be divided into 1#, 2# and 3# three different threadiness drawing stamp, touches and loftex hot stamping film.
