| 1 | Bottle Capacity | 10 ml, 30 ml, 50 ml, 75 ml, and 100 ml are common formats. | Choose the capacity according to the product position. Small sizes suit samples, travel products, and discovery sets, while 50–100 ml formats are more suitable for regular-use perfumes. | Compare the stated nominal capacity with the required fill volume and leave suitable headspace for filling and closure fitting. |
| 2 | Aluminum Grade and Inner Protection | Common options include aluminum containers with an internal lacquer, coating, or compatible liner. | Select an interior treatment that is suitable for alcohol-based fragrance, essential oils, or other ingredients in the formula. | Request compatibility information and perform a storage test using the actual fragrance formula before mass production. |
| 3 | Closure and Neck Compatibility | Typical closures include screw caps, crimp pumps, fine-mist sprayers, and roll-on fittings. | Make sure the bottle neck, thread, crimp profile, dip tube, gasket, and actuator are designed as one matching system. | Check neck dimensions, closure torque or crimp specifications, leakage performance, and spray output with assembled samples. |
| 4 | Customization Options | Available treatments may include anodizing, colored coating, embossing, debossing, screen printing, labeling, and laser marking. | Choose finishes that support the desired appearance while remaining resistant to rubbing, fragrance contact, and normal handling. | Review a physical decoration sample for color consistency, logo placement, adhesion, scratch resistance, and readability. |
| 5 | Shape, Dimensions, and Ergonomics | Common shapes include cylindrical, rectangular, oval, and compact travel formats; dimensions vary by capacity and closure. | Confirm that the bottle is comfortable to hold, stable when placed upright, and suitable for the intended carton or gift set. | Measure height, diameter or width, base stability, total height with closure, and available label or decoration area. |
| 6 | Leak, Pressure, and Surface Performance | Performance checks should cover leakage, closure security, coating adhesion, corrosion resistance, and transport handling. | Select a construction that can withstand filling, storage, shipment, temperature variation, and repeated opening and closing when applicable. | Conduct upright and inverted leak tests, vibration or transport simulation, temperature cycling, and surface inspection after testing. |
| 7 | Quantity, Sampling, and Compliance Documents | Samples should be evaluated before confirming the production quantity, packaging method, and delivery schedule. | Confirm minimum order quantity, sample lead time, production tolerance, packing configuration, inspection criteria, and applicable packaging requirements. | Approve a signed sample or specification sheet and retain test records for capacity, dimensions, decoration, closure fit, and leakage results. |
