The quality of cosmetic packaging needs to be checked during the production process, so that the specified value is kept within a reasonable range. After purchasing products, consumers should check the packaging to determine whether the product packaging meets the manufacturing technical requirements and whether it is damaged during transportation.
Consumers must not check packaging products, which is related to their own interests. If there is too much information to be inspected, you can choose the method of sampling inspection. However, no matter what method is used, the following procedures need to be carried out: 1. Formulate evaluation specifications for packaging technology scope. 2. Use credible tools and inspection methods. 3. Record the data. 4. Provide valid opinions through the test results.
The shape of the glass bottle is limited by the type and quantity of the product. After the shape of the glass bottle is determined, the sample pattern needs to be drawn. Generally, the front view, side view, top view, etc. are selected. The position of the bottle mouth also needs to be enlarged by a partial position. image.
The size of the glass bottle needs to be marked on the drawing, giving tolerance, volume or capacity. Dimensions and tolerances need to be customized with the manufacturer, because the manufacturer's machine has limitations. Generally, the height of the common machine to the bottle can is between 25-300MM. The diameter of the bottle is related to the quantity produced by the machine. The diameter is generally between 12-150MM.
Because of the influence of some external factors during the manufacturing process, the shape and size will be different, so it is necessary to give an acceptable range of varying sizes or tolerances. Standard tolerances are suitable for volume (ML), mass (KG), diameter (MM) and height.
