45.8mm Black A-PET Plastic Round Sealing Disc

What this packaging is

Precision-fit at 45.8mm, this black A-PET round sealing disc is engineered specifically for the Sirius 30ml Cosmetic Jar, sitting cleanly between the product and the lid to create a functional barrier that protects formulas and finishes the interior with a polished look. At just 1 gram and 3.5mm in height, it's lightweight enough for efficient production handling without sacrificing the snug fit that keeps contents secure. The matte black finish pairs naturally with deep-toned Miron glass jars, supporting a cohesive premium aesthetic. Manufactured in Europe, it suits creams, powders, and balms, and is available with stock availability for smaller orders.

Why brands choose this

• Built for a specific jar, no guesswork required: Designed to fit the Sirius 30ml Cosmetic Jar exactly, this disc drops into production workflows without compatibility testing or modification — saving brands development time and reducing component risk.
• Black finish that earns its place on shelf: The matte black disc creates a clean visual break between product and lid, complementing deep-toned glass packaging and reinforcing a premium, intentional aesthetic that reads as considered design rather than an afterthought.
• European manufacturing with stock availability for smaller orders: Produced in Europe and available in smaller quantities through stock availability, this component gives brand teams the flexibility to test, reorder, or run limited editions without committing to large bulk runs upfront.
