Shrink Wrapping Machine
Here is a comprehensive comparison and specification breakdown of Automatic and Semi-Automatic Shrink Wrapping Machines, which are used to wrap products (like bottles, boxes, cans, etc.) with shrink film and heat to seal them tightly.
🔧 1. Automatic Shrink Wrapping Machine – Specification
These machines handle film feeding, sealing, shrinking, and product conveying automatically.
Feature | Specification |
Operation | Fully automatic – product feeding, wrapping, sealing, and shrinking |
Speed | 10 – 60 packs/min (depends on model and pack size) |
Product Types | Bottles, cans, cartons, jars, trays |
Film Type | LDPE, Polyolefin, PVC (shrinkable) |
Film Thickness | 40 – 100 microns |
Sealing System | L-bar sealer / sleeve wrapper with hot knife or impulse sealing |
Shrink Tunnel | Electric or steam-based with adjustable temp (100–250°C) |
Max Product Dimensions | L: up to 800 mm, W: up to 500 mm, H: up to 400 mm (varies) |
Conveyor Type | Roller or mesh belt with variable speed drive |
Control System | PLC with touchscreen HMI |
Power Requirement | 8 – 20 kW (depending on tunnel size) |
Air Requirement | 5 – 6 bar (for pusher or sleeve type) |
Material Construction | SS304 or powder-coated MS |
Safety Features | Emergency stop, overload protection, auto shutdown |
Popular Brands | Multipack, Sevan, Webomatic, Krones, Sidhivinayak |
🛠️ 2. Semi-Automatic Shrink Wrapping Machine – Specification
Semi-auto systems require manual product loading or film feeding. Ideal for low to medium volume production.
Feature | Specification |
Operation | Manual loading → automatic/semi-auto sealing and shrinking |
Speed | 4 – 12 packs/min |
Product Types | Bottles, boxes, trays, cans |
Film Type | LDPE, Polyolefin, PVC |
Film Thickness | 40 – 80 microns |
Sealing System | Manual or pneumatic L-bar/sleeve sealer |
Shrink Tunnel | Electric heating chamber, 100–250°C |
Max Product Dimensions | L: 500 mm, W: 400 mm, H: 250 mm (typical) |
Conveyor Type | Manual or semi-auto with basic drive |
Control System | Timers, basic switches, temperature controller |
Power Requirement | 3 – 8 kW |
Material Construction | MS frame or SS304 for hygiene areas |
Labor Required | 1–2 operators |
Popular Brands | Gempac, Akanksha, Packtech, Allpack Engineers |
🔄 Automatic vs Semi-Automatic Shrink Wrapping
Feature | Automatic | Semi-Automatic |
Speed | High (10–60 ppm) | Low to Medium (4–12 ppm) |
Labor Requirement | Minimal (1 monitor) | Medium (1–2 operators) |
Precision | High | Operator dependent |
Film Wastage | Low | Medium |
Cost | Higher investment | Lower cost |
Best For | Large production lines | Startups, SMEs, batch packing |
Integration | Inline with filling/labeling lines | Standalone use |
