Abstract
The present invention provides a multilayer plastic bottle comprising layers of PET and a polyamide such as, for example, MXD6, that is free from occurrence of delamination upon dropping or upon exposure to impact. The present inventors have found that when forming a barrier layer containing an adhesion promoting agent according to the present invention, an impact energy applied to the barrier layer is well reduced and the resultant multilayer bottle is improved in interlaminar bonding strength and prevented from suffering from delamination upon dropping, etc.
