Question

In __________ no sealing is required.

(a) Plating

(b) Laminating

(c) Stretch wrapping

(d) Shrink wrapping

I had been asked this question in a national level competition.

My question is taken from Thermoplastic Polymers in section Thermoplastic Polymers Properties & Processing of Food Packaging Technology

Answer 1

Right choice is (c) Stretch wrapping

Explanation: In stretch wrapping, no sealing is required. Its main function is pallet unitizing. During stretch wrapping, the material is covered in such a way that the film’s elasticity holds the load tightly together and hence, no sealing is required.
