Question

For Flame Treatment prior to laminating and coating, the temperature time combination is _____

(a) 2000-4000°C, 5s

(b) 1000-2800°C, 1s

(c) 3000-5000°C,10s

(d) 1000-2800°C, 15s

The question was posed to me in an online quiz.

I need to ask this question from Coating and Laminating in Thermoplastics topic in section Thermoplastic Polymers Properties & Processing of Food Packaging Technology

Answer 1

Correct option is (b) 1000-2800°C, 1s

The best explanation: For Flame Treatment prior to laminating and coating, the temperature time combination is 1000-2800°C, 1s. If the temperature or time increases, the film degrades and becomes weak. If the temperature or time is less than required, the film would have a lower surface energy than required.
