Our hot water shrink tunnels complement vacuum packaging machines and vacuum chamber belt machines with an automated shrinking process. After vacuuming and sealing, the packaged product passes through a hot water shower system, where a suitable shrink bag contracts evenly and tightly around the product.
The continuous process is particularly suitable for higher production volumes. Conveyor speed and temperature can be adjusted to different products and packaging requirements. The stable product position throughout the process also facilitates downstream operations such as conveyor handling, robotic handling or palletizing.
Our hot water shrink tunnels can be integrated with vacuum packaging machines and vacuum chamber belt machines to create a continuous, automated packaging line.
Our Shrink Tunnels with hot water shower process deliver consistent, hygienic and efficient results for vacuum-packed food and non-food products. They combine simple operation with high process reliability.
What our technology offers you:
After vacuuming and sealing, the product is transported into the hot water shrink tunnel in a suitable vacuum shrink bag. Inside the tunnel, the package is exposed to controlled hot water via the integrated shower system.
The heat causes the shrinkable packaging material to contract tightly around the product. The packaged product then leaves the tunnel via the conveyor and can be transferred to subsequent processing steps.
Water temperature and conveyor speed can be adjusted according to the product, packaging material and required shrink result.
Our Hot Water Shrink Tunnels are versatile and the perfect complement to vacuum machines and Vacuum Chamber Belt Machines. They ensure hygienic, durable and visually appealing packaging – both in the food industry and in the non-food sector. Continuous throughput and precise temperature control ensure consistent quality and product protection, even at high production volumes.
Typical areas of application:
Our DEAPST2 shrink tunnels offer robust construction, high efficiency and flexible equipment. In addition to the standard version, various options are available to optimally adapt the machine to your production requirements.

Vacuum Bags
Vacuum bags have ideal barrier properties and are the ideal protective packaging for food, especially fish, meat and vegetables.
Thermoforming Film
Thanks to its multi-layer structure, the thermoforming film guarantees an ideal barrier effect and achieves top marks in terms of strength, moisture and oxygen barrier properties, heat resistance and weather resistance.
Vacuum Sealing Machine
Powerful vacuum technology for professional preservation and packaging of food and sensitive products with significantly extended shelf life.
Vacuum Chamber Belt Machine
Automated vacuum packaging of meat, fish, cheese, ready meals and non-food products at high cycle rates. Hygienic, efficient and reliable.
Infeed & Output Technology
Intelligent transport solutions for optimised and smooth material flow in production lines.
Metal Detectors & Checkweighers
Intelligent quality assurance systems for reliable detection of foreign objects and weight deviationsOur metal detectors & checkweighers.
Weighing & Filling Systems
High-precision dosing and filling technologies for consistent product quality and minimal material losses.
A Hot Water Shrink Tunnel is used after vacuuming to apply the film tightly and evenly to the product. This gives you hygienic, durable and visually appealing packaging. The tunnel perfectly complements our Vacuum Machines and Vacuum Chamber Belt Machines in the production line.
Our Hot Water Shrink Tunnels are suitable for many products: meat and sausage products, fish, cheese, ready meals, baked goods, chocolate, fruit, vegetables and non-food items such as cosmetics or medical products. In combination with our Vacuum Bags and Thermoforming Films, you get the right packaging solution for your industry. Get in touch with us: info_at_alphapack.de
Hot Water Shrink Tunnels work with a water curtain that completely surrounds the product. This ensures particularly even results and a smooth packaging surface. Hot air systems are simpler, but less consistent. For high-quality food packaging, we clearly recommend the hot water process.
Yes, our Shrink Tunnels can be flexibly integrated into existing lines and combined with filling systems, labellers, metal detectors or palletisers. Together with our Vacuum Chamber Belt Machines, this creates a continuous packaging solution – from vacuuming to perfect shrink wrapping.
As a manufacturer, we offer you a complete packaging line including packaging materials. Get in touch with us: info_at_alphapack.de
Our Shrink Tunnels are compatible with shrink films and sealing films. As a manufacturer, we not only supply you with the machine, but also with the appropriate packaging material: vacuum bags and thermoforming films tailored to your products.
We advise you on the optimal packaging solution for your needs: info_at_alphapack.de
Various types of film can be used in Shrink Tunnels, for example polyolefin (POF), polyethylene (PE) or special sealing films. Each film has its own shrink behaviour and reacts differently to hot water or hot air. The right temperature and the appropriate process are crucial to ensure that the packaging shrinks evenly. If the wrong film is chosen, wrinkles, damage or an uneven appearance may result. That's why we not only supply you with the right Shrink Tunnel, but also the appropriate shrink and vacuum films that are perfectly suited to your products.
As a manufacturer, we not only advise you on your optimal packaging line, but also offer you the right packaging material.

The price depends on factors such as performance, heating type (electric or steam), degree of automation and accessories. We will advise you individually and provide you with a suitable quote. Contact us by email at info_at_alphapack.de or by telephone on +49 2235 79479 0.
Many customers ask how large the tunnel needs to be and how fast the conveyor belt should run. This depends on the product size, film material and desired production output. The width, height and length are important, as is ensuring that the tunnel is compatible with your existing production line.

A Shrink Tunnel can operate in a very energy- and resource-efficient manner if it has the right equipment. Insulated tanks ensure that heat loss is reduced and less energy is required. A timer function allows automatic heating to be controlled so that the tunnel only consumes energy when it is actually needed. In addition, efficient heating elements can significantly reduce power consumption. There are also opportunities to optimise water consumption, for example through economical hot water showers. In combination with recyclable films, this creates a packaging process that is not only efficient but also sustainable.
