The dimensions of Paper packaging External valve port vary, depending on the overall size of the paper bag, application requirements and filling equipment requirements. The following is a detailed explanation of the dimensions of Paper packaging External valve port:
1. Basic size range
The dimensions of Paper packaging External valve port usually include parameters such as bag width, length and height. Among them, the bag width is the maximum width at the opening of the valve mouth, and the common width ranges from 10mm to 50mm, which depends on the characteristics of the material to be filled and the adaptability of the filling equipment. The length of the valve mouth depends on the overall size of the paper bag, and the length range can range from tens of millimeters to hundreds of millimeters. The height refers to the vertical distance from the surface of the paper bag to the bottom of the valve mouth, which is usually related to the capacity and shape of the paper bag.
2. Customized size
For some special application scenarios, such as food, chemical, pharmaceutical and other industries, it may be necessary to customize Paper packaging External valve port of specific size. These customized sizes are usually based on the specific needs of customers, such as the interface size of the filling equipment, the physical properties of the packaging content (such as fluidity, density, etc.), and the market positioning of the final product. Therefore, the range of customized sizes is very wide, and it is necessary to design and produce according to the actual situation.
3. Dimension tolerance
In order to ensure that the Paper packaging External valve port can perfectly match the filling equipment, its dimensional tolerance needs to be strictly controlled. Common tolerance ranges include ±1mm to ±5mm for bag width, ±5mm to ±10mm for length, etc. The specific values of these tolerance ranges depend on the material of the paper bag, the manufacturing process, and the particularity of the application scenario.
4. Structural dimensions
Paper packaging External valve port is usually composed of multiple layers of materials, including kraft paper, plastic film, etc. These material layers have different thicknesses and sizes, which together constitute the overall structure of the valve port. When designing the structure, factors such as material strength, wear resistance, and sealing need to be considered to ensure the stability and reliability of the valve port during use. At the same time, the shape of the valve port may also affect the size specifications. For example, valve ports in round, square, and other shapes may differ in size.
5. Example size
Take a common food packaging paper bag as an example, the size specifications of its external valve port may be as follows: bag width is 25mm, length is 100mm, and height is 20mm. Such size specifications are suitable for most food filling equipment and can meet the needs of general food packaging. However, for different products and application scenarios, these size specifications may need to be adjusted to meet specific needs.
The size specifications of paper packaging external valve port vary depending on application requirements, paper bag size, and filling equipment requirements. When selecting or customizing the valve port size, multiple factors need to be considered comprehensively, such as product characteristics, filling equipment interface size, market demand, etc. By strictly controlling dimensional tolerances and optimizing structural design, it can be ensured that the paper packaging external valve port has good sealing performance and user experience.
