Key parameters for PP plastic ampoules include specifications (1.5–5 ml), dimensional tolerance (≤0.2 mm), plastic type (PP), and surface treatment (silk-screen printing).
Notably, strict control over dimensional tolerance directly impacts both sealing integrity and user experience; for instance, an excessive deviation in the bottle neck diameter can result in difficulties when snapping the ampoule open or lead to liquid leakage.
During the manufacturing process, rigorous testing of parameters-such as bottle wall thickness and stress line strength-is conducted to ensure that every production batch meets established standards.
Furthermore, the simple packaging design-utilizing small outer plastic bags-serves to further reduce transportation costs.
