Motor oil is an engine lubricant that is used for lubricating internal combustion engines or moving parts. The main function of these lubricants is to reduce wear on moving parts; they also clean, inhibit corrosion, improve sealing, and cool the engine by carrying heat away from moving parts.
Motor oils are derived from petroleum-based and non-petroleum- synthesized chemical compounds. It can be either mineral, semi-synthetic or synthetic.
Target & requirements
The target was to replace commonly used HDPE containers with PET containers with similar shapes. Target PET containers’ weight should be lower. Containers’ main features should be: easy to handle and pouring easiness. Square or rectangular shapes are preferable to have a good arrangement in box or packed on pallet.
Development & challenges
Chemical compatibility between plastic PET and content has to be previously checked. Biggest challenge is to produce an asymmetrical bottle with oval shape, with or without an off-center neck. Also, rectangular profile and sharp edges have to be well designed and formed during blowing and particular attention has to be put in case of long neck or high/sloped shoulder during production process.SFL with preferential heating
or ECS SP
Sipa machines are suggested for the manufacturing of these containers.
Results & Packaging Features
The new PET bottles were 10-15% lighter than the HDPE containers.
Containers can be transparent or with opaque colours.
