A Shrink Tunnel Machine for Bottles is a heat-application packaging unit used to wrap, bundle, or label bottles using heat-shrink film. There are two main bottle applications: bundling multiple bottles together as a multipack (such as 6-pack or 12-pack water bottles) and applying full-body sleeve labels to individual bottles (such as juice, soft drinks, or pharmaceutical syrup bottles). Both applications use a temperature-controlled tunnel chamber with a conveyor belt—the difference lies in the type of film, the upstream equipment, and whether you use hot air or steam.
Amarpack Machines Pvt. Ltd. has been manufacturing shrink tunnel machines for bottles in India since 1998. Our machines run on bottling lines for Tata’s water plants, Cipla’s pharmaceutical syrup units, Dabur’s cosmetic facilities, and dozens of regional juice and beverage manufacturers—wrapping, bundling, and labeling everything from 200 ml medicine bottles to 5-litre edible oil jars.
This page explains the two bottle packaging methods, the right machine for your bottle type, and what each option costs in India.
Used to bundle multiple bottles together into a single retail or transit pack. The bottles are grouped, wrapped loosely in POF or PE film by a web sealer, and pass through a hot air shrink tunnel where the film contracts tightly around the multipack. This is the dominant method used by:
Recommended setup: Automatic Web Sealer with Heavy-Duty Shrink Tunnel (Amarpack APH series).
Used to apply a printed shrink film sleeve to individual bottles — either as a tamper-evident neck band, a half-body label, or a full-body wrap-around sleeve. The pre-printed sleeve is positioned on the bottle by a sleeve applicator, then shrunk tightly by a steam tunnel (for premium finishes) or a hot air tunnel (for general use). This is the preferred method for:
Recommended setup: Sleeve Applicator + Steam Heat Shrink Tunnel (Amarpack steam series) for premium finishes, or Sleeve Applicator + Hot Air Tunnel for cost-effective production.
The process is simple, but the engineering inside the chamber decides whether your packs come out smooth or wrinkled. There are three stages:
1. Pre-wrap. The product is loosely wrapped or sleeved in shrink film by an L-sealer, web sealer, or sleeve applicator placed before the tunnel.
2. Heat application. The wrapped product enters the tunnel chamber on a conveyor. Calibrated heating coils warm the air, and an internal blower circulates that hot air uniformly across all four sides of the product. The film softens and contracts within seconds.
3. Cool-down and exit. The product exits the tunnel with the film tightly fused around it. A short cooling zone — either ambient or fan-assisted — sets the film and prevents post-shrink distortion.
The quality of the final pack depends on three variables that a good shrink tunnel machine controls precisely: chamber temperature, conveyor speed, and air-flow direction. Cheap tunnels get one or two right. A well-engineered industrial unit gets all three right, every time, for years.
For 200 ml to 2 litre PET water bottles bundled into 6, 12, or 24-pack multipacks. Used by mineral water plants nationwide.
For 250 ml to 1 litre PET juice bottles, both as multipacks and as individual full-body sleeve labels. Steam tunnel preferred for premium juice brands.
For 500 ml to 5 litre edible oil bottles in PET, HDPE, or glass. Heavy-duty tunnel for transit-grade multipack bundling.
For full-body shrink sleeves on shampoo, conditioner, lotion, and premium cosmetic bottles. Steam tunnel recommended for wrinkle-free finish on contoured bottle shapes.
For tamper-evident sleeves and full-body labels on syrup bottles, dropper bottles, and oral liquid containers. PVC and PETG sleeve compatible. Used by Cipla, Sun Pharma, Glenmark, Alkem, Intas.
For glass beverage bottles, sauce bottles, pickle jars, and premium liquor bottles. Steam tunnel ensures uniform shrink on glass without thermal shock.
For tamper-evident neck bands and full-body sleeves on whisky, vodka, gin, and wine bottles. Excise-compliant tamper evidence built in.
For branded sleeves on milk, buttermilk, lassi, and flavoured dairy bottles. Tamper-evident options for cold chain distribution.
For PET and aluminum can multipack bundling — 6-can, 12-can, 24-can configurations. Built for high-throughput beverage and FMCG lines.
Three variables decide which machine fits your line:
1. Bottle material. PET and plastic bottles work with both hot air and steam tunnels. Glass bottles prefer steam (lower thermal shock risk). HDPE and high-temperature plastics need precise temperature control to avoid distortion.
2. Application type. Multipack bundling needs a wider tunnel chamber, longer conveyor, and POF/PE film compatibility. Sleeve labeling needs a narrower chamber with focused heat zones for the sleeve area only.
3. Production speed. For 50-150 bottles per minute, semi-automatic L-sealer + tunnel works. For 150-300 BPM, fully automatic web sealer + heavy-duty tunnel. For 300+ BPM (high-volume water or soft drinks), inline collator + multi-zone tunnel with rapid heat recovery.
If you are unsure which configuration fits your bottle and production target, our application engineers will recommend the right setup based on a sample bottle and your daily output.
