23rd Happy Conference Report: Spreading Joy and Unity
Guan Yi Container's 23rd Happy Conference gathered the whole team in Dongguan for welcome ceremonies, department awards and a birthday celebration.

Standard PET and PE bottles from existing tools, or a custom mould for food, medical, cosmetics and industrial fills. Moulding, decoration and packing in one plant in Dongguan.
Standard bottles come from existing tools; custom projects start with a mould and are organised by the application they serve.

PET bottles from 10 mL to 120 mL and PE bottles from 250 mL to 2.5 L, moulded on tools that already exist.

A bottle usually fails at a hand-over: the moulder blames the decorator, the decorator blames the capper. We keep tooling, printing, coating and export packing in the same plant, so one project engineer owns the part from drawing to pallet.
