Electric Shrink Sleeve Tunnel | Steam Shrink Sleeve Tunnel
An electric shrink sleeve tunnel and a steam shrink sleeve tunnel are both used for heat shrink packaging, but they differ in heating methods and applicable scenarios. Here are the main differences: 1. Heating Method: Electric Shrink Sleeve Tunnel: This uses electric heating elements (like heating tubes or infrared heaters) to generate heat, warming the air and circulating it to heat the shrink film. This method heats up quickly and can rapidly reach the required shrink temperature. Steam Shrink Sleeve Tunnel: This uses steam heat to shrink the packaging, providing a more even heat distribution that helps avoid localized overheating and is gentler on the product surface, reducing potential film damage. 2. Suitable Film Materials: Electric Shrink Sleeve Tunnel: Typically used for films like PVC or POF, which are suited for rapid heating and shrinking. Steam Shrink Sleeve Tunnel: Better suited for PET and other materials that require even heat distribution, especially for products requiring high transparency and precise packaging. 3. Application Scenarios: Electric Shrink Sleeve Tunnel: Commonly used for products with less stringent shrink packaging requirements, such as everyday consumer goods, stationery, and cosmetics. Steam Shrink Sleeve Tunnel: Frequently used for high-end packaging, such as beverage bottles and cosmetic containers, especially for plastic labels that need to fit tightly around the bottle. 4. Energy Consumption and Maintenance: Electric Shrink Sleeve Tunnel: Generally has higher electricity consumption, but a simpler structure with lower maintenance costs. Steam Shrink Sleeve Tunnel: Requires a steam generator and piping system. Though it consumes less energy, it needs additional steam equipment and piping maintenance. In summary, an electric shrink sleeve tunnel is better suited for quick heating and more economical applications, while a steam shrink sleeve tunnel is ideal for high-end products requiring precise heat distribution and a more refined shrink effect.
