| titleOfInvention | Twisted Polyester Film |
| abstract | The present invention relates to a polyester film for excellent twist packaging that can be used for individual packaging such as candy, chocolate, caramel and the like, as well as for flowers or other gift packaging, wherein the elongation value (MD) in the elongation value of the film is in the transverse direction (TD). Small compared to the elongation value and the difference is within 10-30%; Fold holding angle obtained by calculating the angle (θ) of the folded part in half under the condition of pressure 0.2MPa, pressurization time 1 sec. And 60 ° or less in transverse direction; Using a twist gauge, apply tension to both ends of the film under a load of 270 g, then twist 20 laps, remove the grip, and let it stand at room temperature for 24 hours. The kink retention rate derived by is 65% or more; It is characterized by a density of 1.30 to 1.37 g / cm3 measured by a 25 ° C thermostat density tube, and such a polyester film inherently has excellent mechanical properties, printability, transparency, thickness uniformity, and cutting. It is useful as a packaging material such as candy, caramel or chocolate packaging material with excellent kinkability and kink retention rate while having sex and harmlessness.n n n n Equation 1n n n n θ = 2sin -1 (F / 2L)n n n Where F is the length of the imaginary line between the two ends of the film folded in half, and 2L is the total length of the film folded.n n n n Equation 2n n n n Twist Retention Rate (%) = (X / 20) × 100 |
