| Small, targeted personal care | Lip balm, eye cream, or spot treatment | 5–20 mL | Choose a compact tube that supports controlled dispensing and fits the intended application area. |
| Travel-size skincare | Moisturizer, facial cleanser, or hand cream | 30–100 mL | Allow enough capacity for the expected trip or usage period, while keeping the package easy to carry. |
| Everyday facial care | Cleanser, sunscreen, or facial moisturizer | 50–150 mL | Match the opening and closure to the product’s thickness and the amount users typically dispense. |
| Daily oral care | Toothpaste or tooth gel | 50–150 mL | Consider repeated use, product flow, and whether the tube can be squeezed comfortably as it empties. |
| Family-size personal care | Body lotion, shower gel, or hand wash | 150–300 mL | A larger tube can reduce refill frequency, but should remain stable and manageable during use. |
| Sun protection for regular use | Sunscreen or after-sun lotion | 50–200 mL | Consider how often the product is applied and whether a flip-top cap or other closure suits on-the-go use. |
| Hair styling and grooming | Hair gel, styling cream, or shaving cream | 50–200 mL | Thicker formulas may need a wider dispensing opening; test the package with the actual product. |
| Small-dose topical application | Ointment, gel, or treatment cream | 5–50 mL | Choose a capacity that supports the intended treatment period and a nozzle that enables precise application. |
| Food dispensing | Sauce, condiment, or decorative food topping | 100–500 mL | Use packaging materials and closures suitable for the food and filling process; check dispensing and storage requirements. |
| Craft or household application | Craft glue, repair gel, or cleaning paste | 10–100 mL | Base the capacity on the amount needed per task, and confirm that the tube material is compatible with the formulation. |
