Buying PET preforms may look simple from the outside, but every packaging manager, bottling plant owner, and FMCG procurement head knows one thing: one wrong decision can cost lakhs in losses. From poor-quality preforms that crack during blow moulding to suppliers who fail to deliver on time, the mistakes often go unnoticed until it’s too late.
Whether you're a new brand entering the beverage market or an established bottler scaling operations, understanding these mistakes will save money, time, and frustration. As a leading PET preform supplier, Frystal Pet has worked with businesses who learned these lessons the hard way and those who avoided the problems altogether.
