The plastic spout shown in your image is a specialized ​​packaging component​​ designed for liquid or semi-liquid dispensing. Here’s a detailed breakdown of its features, applications, and industry context:

​​1. Design & Technical Specifications​​
​​Material:​​ Likely ​​food-grade polyethylene (HDPE/PP)​​ or PET—chosen for durability, chemical resistance, and safety compliance.
​​Structure:​​
​​Top Nozzle (25.0mm outer diameter):​​ Features flanges (4.8mm width) for secure attachment to pouches or bottles.
​​Flow Channel (22.0mm inner diameter):​​ Optimized for medium-to-high viscosity liquids (e.g., sauces, syrups, oils).
​​Hexagonal Base (42.2mm width):​​ Provides anti-rotation stability during filling/sealing processes.
​​Total Height (34.2mm):​​ Compact for space-efficient integration into packaging.
​​2. Primary Applications​​
​​Flexible Packaging:​​ Used in ​​stand-up pouches​​ (e.g., for baby food, detergent, beverages).
​​Industrial Liquids:​​ Dispensing oils, lubricants, or chemicals in bulk containers.
​​Food & Beverage:​​ Common in condiment packets, drink pouches, or dairy products.
​​3. Functional Advantages​​
​​Leak-proof:​​ Flanges create a tight seal when heat-sealed or screwed onto packaging.
​​User-friendly:​​ Wide opening allows easy pouring without clogging.
​​Machine Compatibility:​​ Hex base ensures stability during high-speed filling operations.
​​4. Industry Context​​
​​Supplier Link (www.valuepackaging.cn/store):​​ Suggests this is a ​​customizable OEM/ODM component​​ for packaging manufacturers.
​​Standards:​​ Likely complies with ​​FDA (food contact) or EU 10/2011 regulations​​ if used for consumables.
​​5. Purchasing Considerations​​
​​Minimum Order Quantity (MOQ):​​ Common for such components (e.g., 10,000+ units for cost efficiency).
​​Customization:​​ Colors, diameters, or antimicrobial additives can be tailored.

This image is a detailed technical illustration of a ​​multi-tiered plastic spout​​, likely designed for liquid dispensing (e.g., for bottles, pouches, or industrial packaging). Here’s a breakdown of its features and purpose:

​​1. Key Design Features​​
​​Material:​​ Made of opaque white plastic (likely HDPE, PP, or PET for durability and food safety).
​​Structure:​​
​​Top Cylindrical Nozzle:​​ Features multiple ​​ring-shaped flanges​​ (凸缘) for secure attachment to containers or tubing.
Outer diameter: ​​25.0mm​​
Inner diameter (flow channel): ​​22.0mm​​
One flange width: ​​4.8mm​​ (provides grip or sealing points).
​​Hexagonal Base:​​ Flat six-sided mount with:
Width (across flats): ​​42.2mm​​
Central hole diameter: ​​25.0mm​​ (possibly for threading or locking mechanisms).
​​Total Height:​​ ​​34.2mm​​ (compact for space-efficient packaging).
​​2. Functional Purpose​​
​​Liquid Dispensing:​​ The wide inner diameter (22mm) suggests high-flow applications (e.g., viscous liquids, powders, or industrial fluids).
​​Secure Attachment:​​ The flanges and hexagonal base allow for:
Twist-lock installation into caps or machinery.
Anti-rotation stability during use.
​​Common Uses:​​ Found in ​​flexible pouches, liquid packaging, or bulk containers​​ (e.g., for sauces, chemicals, or automotive fluids).
​​3. Technical & Commercial Context​​
​​Image Style:​​ A ​​CAD-rendered or precision-measured product photo​​ with clear dimension labels, typical for manufacturer catalogs or e-commerce listings.
​​Watermark:​​ Links to ​​www.valuepackaging.cn/store​​, indicating this is a ​​customizable spout​​ sold by a packaging supplier (likely for B2B buyers).
​​4. Why These Details Matter​​
​​Precision Fit:​​ The exact dimensions ensure compatibility with specific filling machines or containers.
​​Material Choice:​​ Food-grade or chemical-resistant plastics would be specified for safety.
