Precautions
  • Torque Calibration for Capping Machines: When deploying these ribbed caps on automatic production lines, please calibrate the capping machine's torque appropriately. Excessive torque can deform the double-coated PE liner, while insufficient torque may compromise the airtight seal.
  • Chemical Sealing Compatibility Check: Although the double-coated PE liner offers vast chemical resistance to most essential oils and solvents, highly aggressive chemical formulations should be pre-tested. We provide complimentary samples for your quality control team to perform a 48-hour compatibility test.
  • Strict Storage Environment Guidelines: To maintain the shape of the plastic caps and the optimal elasticity of the PE liners, bulk inventory should be stored in a cool, dry warehouse away from direct sunlight, UV exposure, and heat sources.
  • Complete Packaging Solution Sourcing: For a guaranteed 100% leak-proof fit, we highly recommend purchasing these closures alongside our matching DIN 18/410 amber glass essential oil bottles, eliminating any micro-tolerance variance between different manufacturers.
