Power Sealer ©

Power Sealer is the name of Audion’s range of industrial compressed-air-operated impulse sealers with bi-active sealing bars and a stainless steel housing. They are designed for bags requiring a strong, reliable seal: food products, parts, medical supplies and high-tech components. The range extends from a time-controlled entry-level model to fully validatable, cleanroom-certified and explosion-proof versions, all available with vacuum and MAP if required.

The range comprises the entry-level model (5 mm, time-controlled), the Power Sealer TC (temperature-controlled), the Validatable Power Sealer, the Power Sealer PLUS (the most precise validation), the PLUS IP65 (dust-tight and splash-proof), the PLUS IP65 Bag-in-Box, the TC XL and PLUS XL (2500 mm), and the steam-powered Power Sealer EX. Base your choice on four factors: validation requirements, environment, seal length and whether you need vacuum packaging.

Audion does not publish machine prices because each Power Sealer is configured according to seal length, validation, vacuum system and options. Prices for wear parts are available in the webshop.

Bag sealer, plastic sealer, plastic bag heat sealer and heat sealer for plastic bags all refer to a device that closes a plastic bag using heat and pressure. The difference lies in the design: from a hand sealer for occasional bags to an industrial compressed-air-operated sealer for daily use. The Audion Power Sealer belongs to the latter category.

With a hand sealer or sealing tongs, the operator applies pressure manually, so it varies from one seal to the next. A Power Sealer applies pressure using compressed air, ensuring consistent force. It is started with a foot pedal to keep both hands free, produces seals up to 2500 mm long and stores settings for each product as a recipe. A hand sealer is often sufficient for small volumes and thin film; a Power Sealer is needed for thick film, vacuum packaging or applications where process validation matters.

A power sealer makes one seal per cycle while the bag remains stationary, making it ideal for heavy bags, vacuum packaging and controlled sealing. A band sealer or continuous sealer seals continuously as bags pass through it, which is useful for large quantities of identical bags. An L-sealer uses shrink film and is usually combined with a shrink tunnel that shrinks the packaging around the product for a tight fit. Audion supplies all three machine types.

With a constant-heat sealer, the sealing bar stays hot continuously. An impulse sealer heats the sealing wire only briefly during sealing, after which the seal cools under pressure before the bars open. This produces a neat [sentence incomplete in the Dutch source]. Heat sealers are often better suited to laminated films. All Power Sealers are impulse sealers; sealing and cooling times can be set for each film, as can the sealing temperature on TC and PLUS models.

With a nozzle vacuum sealer, the bag stays outside the machine; a nozzle extracts the air, after which the bag is sealed. This also allows very large bags, big bags or bags inside a box to be processed. With a vacuum chamber machine, the entire bag is placed inside a closed chamber. Vacuum Power Sealers use a nozzle; Audion also supplies chamber machines in the Audionvac range (link to Audionvac).

You need a sealer that monitors sealing temperature, sealing time and sealing pressure and triggers an alarm if deviations occur. Within the Power Sealer range, these are the Validatable Power Sealer, the Power Sealer PLUS, the PLUS IP65, the PLUS IP65 Bag-in-Box and the PLUS XL. These models are compatible with EN 868-5 and DIN 58953 Part 7 and comply with ISO 11607-2 and ISO/TS 16775. Audion also provides calibration and IQ/OQ.

The Power Sealer PLUS is certified by the Fraunhofer Institute for ISO Class 5 cleanrooms when combined with the optional external air exhaust system. The PLUS IP65 includes this external air exhaust as standard. Additional cleanroom solutions are available for all validatable models, including a low-silicone machine design (SILA), ESD, external extraction and various filters. White polyamide wheels for the frame are also available for cleanrooms.

Yes, with the Power Sealer EX: a steam impulse sealer that operates without an electrical power supply. Instead of a heated sealing wire, it uses pressurised steam, eliminating an ignition source. The machine is suitable for explosion zones 1 and 2 (Class 1, Divisions 1 and 2) and ATEX.

The entry-level model, TC and Validatable Power Sealer are available in 520, 720 and 1020 mm lengths; the PLUS is also available in 1320 mm. The PLUS IP65 is available in 720 and 1020 mm, the Bag-in-Box in 1720 mm, the Power Sealer EX in 610, 800 or 1000 mm, and the TC XL and PLUS XL in 2500 mm. The entry-level model produces a 5 mm seal; the other models produce an 8 mm seal.

PE (polyethylene), aluminium-laminated bags, special laminates and thick films; the XL models can also seal antistatic film. The entry-level model and TC handle film up to 2 x 300 microns, the Validatable Power Sealer up to 2 x 200 microns, the PLUS models from 2 x 20 to 2 x 300 microns, and the XL up to 400 microns. A thick-film configuration is available for films over 150 microns or multiple layers.

Yes, all Power Sealers use compressed air to press the sealing bars together.

Most models are benchtop machines that can also be mounted on a mobile frame. Only the Power Sealer Bag-in-Box and XL versions are supplied with a stand as standard.

The manual industrial frame (806 x 760 x 1624 mm, 30 kg) offers stepless height adjustment and 90-degree tilting. A motorised frame lets you adjust the sealing height electrically; on PLUS models this can even be done through the recipe. Other options include a roller conveyor, a height-adjustable bag support and worktable, and an electric foot pedal for hands-free operation.

The entry-level model stores 9 recipes and the Validatable Power Sealer uses 1 recipe. The Power Sealer TC, PLUS, PLUS IP65, Bag-in-Box and XL models store up to 50 recipes using Audion Touch Techware. On PLUS models combined with a motorised frame, the working height can also be saved in the recipe.

The standard pump is an oil-free, virtually maintenance-free venturi pump, available in 11 or 20 m³ versions. For large bags, a heavy-duty venturi pump is available with modified pipes, valves and hoses, or a Busch side-channel pump rated at 85 m³/h, also available in an ATEX version. The Bag-in-Box includes a Busch centrifugal pump as standard.

Yes, a cutting device removes the film above the seal. This creates cleaner, smaller packaging and prevents dirt or dust in the bag opening. The entry-level model has a maximum cutting length of 440 mm. A cutting system can be integrated into the TC, PLUS and PLUS IP65, and a pneumatic cutter is optional on XL models.

The wear parts are the PTFE strips, silicone rubber strips and sealing wire. Audion supplies them separately and as a spare parts kit suitable for the 520, 720, 1020 and 1320 models, including TC, PLUS, IP65 and SILA. The parts are easy to replace and available from stock.

In the Audion webshop, under Service & Parts. Individual wear parts and the complete Power Sealer spare parts kit are listed with item numbers and prices, and you can filter by machine type. The electric foot pedal, which replaces the standard foot pedal on PSR models, can also be ordered there. Contact the service department for repairs or calibration.

Yes. Audion has its own certified calibration service, which measures critical process parameters such as sealing temperature, sealing pressure and sealing time using traceable measuring equipment, after which you receive a calibration certificate. Audion performs IQ/OQ for validatable models. On the Power Sealer TC, the sealing temperature can be calibrated through factory calibration. Audion also offers seal integrity testing, including peel testing, seal checks and ink testing.

Yes. Audion offers a no-obligation demonstration with your own product and packaging, at its headquarters in Weesp or through its dealer network. Seal integrity testing (peel testing, seal checks and ink testing) can demonstrate that the seal meets your requirements. Audion also supplies matching film and bags, ensuring the machine and material are compatible.

An impulse sealer with bi-active sealing bars that heat the film from both above and below and apply consistent pressure using compressed air. This is exactly how the Audion Power Sealer works. The entry-level model produces a 5 mm seal and the other models an 8 mm seal, with pressure distributed evenly across the full seal length. This allows PE film and aluminium-laminated bags up to 2 x 300 microns to be sealed, even during intensive use.

By extracting the air from the bag and, if required, replacing it with a protective gas (MAP, modified atmosphere packaging) before sealing. Every Power Sealer can be configured with an integrated vacuum and gas flushing system featuring an oil-free, virtually maintenance-free venturi pump. Audion lists powders, spices, granules and large cuts of meat among the applications and describes case studies involving cheese and chips.

A vacuum sealer removes air from the packaging, reducing package size and the space it occupies in the warehouse and truck. On vacuum Power Sealers, a venturi pump empties the bag through a nozzle, after which the sealing bars close the bag immediately. For large bags, a heavy-duty venturi pump or an 85 m³/h Busch side-channel pump helps extract large volumes of air quickly.

In two ways. Vacuum packaging or MAP prevents metal parts from oxidising during storage and transport and is available on any Power Sealer with an integrated vacuum system. An ESD (Electro Static Discharge) option also protects the operator against electrostatic shocks and prevents damage to electronic components; Audion recommends it for the high-tech market. Digital vacuum control allows fragile electronics to be vacuum-packed gradually and gently.

The Power Sealer PLUS IP65. Its AISI 304 stainless steel housing is dust-tight and splash-proof to IP65, preventing dust and moisture from reaching internal components and making the machine easy to clean. Audion builds this model for applications including food packaging and powder packaging in the pharmaceutical and chemical industries. The Bag-in-Box version is available for vacuum-packing large bags inside a box or drum.

With a Power Sealer XL. The TC XL and PLUS XL have a seal length of 2500 mm, the longest in the Power Sealer range, with an 8 mm seal width and a generous 45 mm sealing-bar opening. This lets you seal custom bags and protective covers in one operation so large products can move safely through the supply chain. A worktable is available to support long, narrow products during sealing.

With the Vacuum Power Sealer PLUS IP65 Bag-in-Box. The box or drum is positioned beneath the sealer using a conveyor, support or Euro pallet; a motorised frame automatically lowers the sealing head and extra-wide vacuum nozzle into the bag, allowing air to be extracted close to the product. The sealing bars are 1720 mm long and produce an 8 mm seal. Multiple vacuum and gas flushing cycles are possible to reduce residual oxygen levels.

Use bag stretchers that pull the bag taut beside the sealing bar to prevent wrinkles in the seal. You can also set sealing and cooling times for each film in a recipe, while the compressed-air-operated bi-active sealing bars distribute pressure evenly along the full bag length. For thick films or multiple film layers, a configuration with special rubber strips and modified settings provides optimum sealing pressure.

Audion offers a powder filter with a quick-cleaning system, a liquid separator and the Particle Ejection System (PES), which blows residual product out of the vacuum system after every vacuum cycle. An external venturi pump, mounted on the frame or rear of the housing, prevents contamination inside the machine and simplifies cleaning. This also prevents cross-contamination with the next product batch.

Bi-active means that both the upper and lower sealing bars are actively heated. Heat therefore enters the film from both sides, producing a complete, uniform seal, especially on thick films and laminates. Compressed air presses the bars together, keeping pressure even across the full seal length. All electrically heated Power Sealers have bi-active sealing bars.

Validatable sealing controls and monitors the main sealing process parameters, such as temperature, time and pressure. Ordinary sealing closes the packaging without controlling all these process parameters. Validatable sealing therefore provides greater control and assurance of the quality and reproducibility of every seal. Validatable Power Sealers automatically flag deviations and can record process data. This is particularly important in sectors requiring a reliable, verifiable sealing process.

MAP stands for Modified Atmosphere Packaging: after air is extracted, the bag is filled with a protective gas before being sealed. For food, this extends shelf life; for medical instruments, it can provide sterile protection; and for electronics and metal parts, it prevents oxidation. Power Sealers allow multiple vacuum and gas flushing cycles for optimum MAP results.
