Shrink Tunnel Machine for Bottles Multipack Wrapping & Sleeve Labeling Solutions Shrink Tunnel Machine for Bottles | Manufacturer India – Amarpack Machines Pvt. Ltd. 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. Get a Quote in 2 Working Hours → The Two Methods of Bottle Shrink Packaging Method 1: Multipack Bundling (Web Sealer + Hot Air Tunnel) 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: Mineral water plants — 6-bottle, 12-bottle, and 24-bottle multipacks Soft drink and beverage producers — 6-pack and 12-pack bundles Edible oil bottlers — multi-bottle retail bundles Wholesale distribution — transit-grade bundling for warehouses and modern trade Recommended setup: Automatic Web Sealer with Heavy-Duty Shrink Tunnel (Amarpack APH series). Method 2: Sleeve Labeling (Sleeve Applicator + Steam or Hot Air Tunnel) 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: Juice and beverage brands — full-body printed sleeves with vivid graphics Pharmaceutical syrup bottles — tamper-evident neck bands Cosmetic and personal care brands — full-body sleeves on shampoo, lotion, conditioner bottles Spirits and liquor brands — premium tamper-evident seals Dairy and milk bottles — branded sleeves with date coding Recommended setup: Sleeve Applicator + Steam Heat Shrink Tunnel (Amarpack steam series) for premium finishes, or Sleeve Applicator + Hot Air Tunnel for cost-effective production. How a Shrink Tunnel Machine Works 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. Bottle Types We Package — Full Application Coverage Amarpack shrink tunnel machines are running in India today for every common bottle category. Here is what we build for each: Water Bottle Shrink Tunnel For 200 ml to 2 litre PET water bottles bundled into 6, 12, or 24-pack multipacks. Used by mineral water plants nationwide. Juice Bottle Shrink Tunnel 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. Oil Bottle Shrink Tunnel For 500 ml to 5 litre edible oil bottles in PET, HDPE, or glass. Heavy-duty tunnel for transit-grade multipack bundling. Shampoo & Cosmetic Bottle Shrink Tunnel For full-body shrink sleeves on shampoo, conditioner, lotion, and premium cosmetic bottles. Steam tunnel recommended for wrinkle-free finish on contoured bottle shapes. Pharmaceutical Bottle Shrink Tunnel 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. Glass Bottle Shrink Tunnel For glass beverage bottles, sauce bottles, pickle jars, and premium liquor bottles. Steam tunnel ensures uniform shrink on glass without thermal shock. Liquor & Spirits Bottle Shrink Tunnel For tamper-evident neck bands and full-body sleeves on whisky, vodka, gin, and wine bottles. Excise-compliant tamper evidence built in. Milk & Dairy Bottle Shrink Tunnel For branded sleeves on milk, buttermilk, lassi, and flavoured dairy bottles. Tamper-evident options for cold chain distribution. Soft Drink & Beverage Can Shrink Tunnel For PET and aluminum can multipack bundling — 6-can, 12-can, 24-can configurations. Built for high-throughput beverage and FMCG lines. Choosing the Right Tunnel for Your Bottle 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 +
