You are right ,Meirs Client sharing is about two products sharing the same client (cliente compartido). On top of that, the other advantage of producing both HDPE and PET is the possibility of sharing costs between the two production lines

meirs, You might be right. I think we need more context to decide for a correct answer.

client sharing versus cost sharing This is how I understand:
client sharing (is not cost sharing with the client) = the same client for HDPE may also be a PET client - so you have one client for two products (two birds with one stone :-) - less expenses and more business volume
cost sharing = maybe sharing costs with the client (unlikely) / maybe manufacturing both HDPE and PET (in the same plant) is less costly than the sum of manufacturing costs of each one separately
