| WYDDDARY Mesh Type Shrink Wrap Machine | High-speed production with 3-phase power | Digital control with clear status indicators |
| HQHAOTWU Shrink Tunnel Packaging Machine | Industrial use with PVC/POF films | Uniform heating and adjustable speed |
| HayWHNKN Industrial Shrink Wrap Machine | Heavy-duty mesh-belt packaging | Leakage protection and observation window |
HayWHNKN Heat Tunnel Shrink Wrap Machine
The HayWHNKN model uses a mesh conveyor belt designed for heavy loads and square product shrinkage. It features a cooling fan and vent for continuous cooling, plus a power overload protection device to prevent overheating. With dual temperature control, users can set upper and lower levels separately, enabling energy efficiency and precise shrinkage. Best for manufacturers packaging varied shapes where stable, even heat is essential. A potential limitation is that the mesh belt may imprint on some delicate, highly polished finishes if contact is high.
LGXEnzhuo 220V Heat Tunnel Shrink Wrap Machine
This model uses a quartz far-infrared tube to heat PVC/POF shrink film, enabling strong compression packaging. It is suitable for packaging foods, beverages, candy, stationery, and hardware tools, including multi-item trays. It adopts a steel mesh conveyor with heat-resistant silica gel insulation to minimize film deformation. Choose this if you need flexible sizing (max 300×150 mm) and a compact footprint. Caution: 0-10 m/min conveyor speed may require slower lines for very delicate items.
WYDDDARY Shrink Wrap Machine
WYDDDARY offers a 7,000W, 220V three-phase system with a 40×35 cm max shrinking size and a 10 kg max feeding weight. Its digital control panel provides easy temperature and speed adjustments, with LED indicators for status. Best for operations needing faster cycles and clear process visibility. Limitation: mesh belt can imprint on products with high bottom contact or strong patterns; use for items with minimal bottom contact or a flat bottom profile.
HQHAOTWU Shrink Tunnel Packaging Machine
HQHAOTWU emphasizes a quartz far-infrared heating tube for uniform heating of PVC/POF films and adjustable upper/lower temperatures with 0-10 m/min conveyor speed. It is designed to match varied shrink film needs and industrial packaging demands. Best for facilities needing consistent heat distribution and flexible film compatibility. Caution: 7000W power draw requires a suitable electrical setup and proper ventilation in tight spaces.
HayWHNKN Industrial Shrink Wrap Machine
This mesh-conveyor model is designed for heavy-duty use with a leakage breaker, transparent observation window, and an intelligent control panel. It highlights fast and even heat distribution with a fan to spread heat in the chamber. Best for larger-scale packaging where operators need to monitor progress. Limitation: mesh belts can leave imprint marks on items with maximum bottom-area contact; consider non-mesh lines for highly delicate bottoms.
Buying Guide
What to consider when selecting a shrink tunnel wrapping machine:
- Conveyor type: Mesh belts provide fast heat transfer but can imprint on sensitive bottoms. Solid belts reduce imprint risk but may heat less evenly.
- Power and electrical needs: Many models are 220V with high wattage; ensure your facility supports three-phase or single-phase as required.
- Temperature control: Look for adjustable upper and lower temperatures, and digital/stepless controls for consistent shrinkage.
- Size and throughput: Check max shrink size, conveyor speed, and feed weight to match your product dimensions and batch sizes.
- Safety features: Overload protection, leakage breakers, cooling fans, and observation windows improve operator safety and uptime.
- Film compatibility: Confirm PVC/POF film compatibility and whether the machine supports tray or multi-item packaging.
FAQ
- What is the typical max shrink size on these machines?
Most models list a max shrink size around 300×150 mm or 15×13 inches, suitable for small to medium items. - Do mesh conveyors cause imprinting on products?
Yes, for items with soft or highly formed bottoms. For delicate items, consider non-mesh lines. - Is three-phase power necessary?
Some models use 3-phase power for high throughput; verify your facility’s electrical capacity before purchase. - How do I adjust temperature and speed?
Most machines offer digital or stepless controls for upper/lower temperature and conveyor speed. - Are these machines suitable for PVC/POF films?
Yes, several models are designed for PVC and POF shrink films with uniform heating. - What maintenance is required?
Regular cleaning, inspection of mesh belts, and checking the cooling system help maintain consistent results.
