• How do I choose the right closure for my product?

  • Product Compatibility: The closure material must be chemically compatible with your product (e.g., resistance to oils, acids, or alcohols) to prevent interaction.
  • Barrier Requirements: Does your product require an oxygen or moisture barrier? We offer closures with specialized liners for enhanced preservation.
  • Functionality: Consider how the end-user will interact with the product (pouring, spraying, dispensing one unit at a time).
  • Tamper Evidence & Safety: Legal requirements or brand trust may mandate tamper-evident or child-resistant features.
  • Brand Image: The closure is a key part of your packaging aesthetics. We offer custom colors, printing, and finishes (matte, gloss) to align with your brand.

• How do you ensure the closure provides a leak-proof seal?

  A leak-proof seal is achieved through the precise combination of the glass bottle finish (the threading and sealing surface) and the closure’s internal sealing mechanism. We use:

  **Liner Seals: A foam, pulp, or plastic liner compressed against the bottle’s lip.

  **Flow-In Liners: A liquid gasket material is dispensed into the cap, forming a perfect seal upon curing.

  **Molded-in Seals: The sealing component is molded directly into the cap during manufacturing.
  We conduct rigorous leak tests (e.g., vacuum decay tests, torque testing) to guarantee performance.

• Can you customize the color, size, and branding on the closures?

  **Color Matching: We can match any Pantone color.

  **Branding: Hot stamping, silk-screen printing, and embossing/debossing of your logo or design are available.

  **Size: We produce closures in a vast range of diameters and heights to fit your specific bottle.

• How can I test if your closure is compatible with my bottle and filling line?

  We strongly recommend testing before full-scale production.

  Samples: We provide production-quality samples of both our bottles and closures for your evaluation.

  Line Trials: We can coordinate to have our components tested on your filling and capping equipment to ensure smooth operation and correct seal application torque.

• How are the closures packaged for shipment to prevent damage?

  Cartons: Most of our caps are packed in cartons in alignment, with pearl foam and dust proof bag to prevent scratches and dust.

  Palletization: All shipments are securely palletized and wrapped to prevent shifting during transit.

• Do you offer stock options for common closure sizes?

  Yes. To help reduce lead times for our customers, we maintain a stock program for popular sizes and styles of standard closures (e.g., 18-410, 18-400, 28-400, 38-400, 50-410, 53-400 neck finishes). Inquire about our stock list for quick-ship options.
