Question

A single laminate layer is thicker than _____

(a) 15 μm

(b) 6 μm

(c) 1 μm

(d) 10 μm

I had been asked this question in an international level competition.

Asked question is from Coating and Laminating in Thermoplastics in section Thermoplastic Polymers Properties & Processing of Food Packaging Technology

Answer 1

The correct choice is (b) 6 μm

To explain: A single laminate layer is thicker than 6µm. A laminate is made up of two or more layers which can be plastic or non-plastic. But at least one layer must be a plastic. All layers to make a laminate must be thicker than 6 μm. However, there is no upper limit for this.
