PF & ESI Compliance To Canteen Worker Working Outside Factory

i shared my citehr experience with one of my friend. he has given us a situation to get a solution:
His factory engaged a canteen contractor to cook food in a kitchen outside the factory and bring food inside during lunch/breakfast time and serve to employees. The contractor engaged 17 contract labours for this activity. Labours used to be inside factory during lunch / breakfast time only.
Is it required that those contract labours should be covered under PF and ESI ?? Out of 17 only 9 used to come inside factory. Rest used to manage kitchen/shopping etc outside only.
The company pays contractor per unit of meal /breakfast basis and a lumpsum amt for his admin cost ( kitchen rent/manning cost/untensil rental, fuel etc).

Yes dear,

Definately, its prime responsibility of Principal Employer.

PF and ESI compliance must be done.

The debate here is that the Company take food on per plate cost and the persons are working partly inside, partly outside and not for 8 hrs. if so, then what about agencies/vendors who supply raw material, spare part, packaging material, ppe, stitched uniforms etc to the company...... in a way these all are linked to manufacturing process directly or indirectly.
Is the Company responsible for such labour /contract labour's (who are engaged in above activities) pf/esi compliance...... ??

No need to give the pf & esi facility, why the principle employer give this facility if e'er paying his bill / payment. if any like that law or requirement then pls share me also, i have also like that problem.
