ASS450-AI

ASS450-AI Shrink Sealing and Wrapping Machine – Sealer and Tunnel Combo

Product Description

The SunAura ASS450-AI is an integrated shrink packaging system that combines an L-bar sealer (ASS450) and a shrink tunnel (BSD3520A) in a single compact unit. This all-in-one design eliminates the need for separate machines and connecting conveyors, saving floor space and reducing installation complexity. The sealer cuts and seals shrink film around the product, then the sealed package passes directly into the shrink tunnel where heat shrinks the film tightly around the product for a professional retail-ready package.

The ASS450 sealer features a 220V power supply, 1.35 KW power, and an infinite sealing length with a 350mm sealing width. The conveyor speed of 15 m/min provides high throughput for medium to high-volume packaging operations. The BSD3520A shrink tunnel features 6.5 KW heating power, a tunnel size of 800x350x200mm, and adjustable speed from 0-15 m/min. The integrated design ensures perfect synchronization between sealing and shrinking, producing consistent, high-quality shrink packages.

Advantages of Integrated Sealer and Tunnel Design

The integrated ASS450-AI design offers several advantages over separate sealer and tunnel machines. First, the compact footprint saves valuable floor space, as the combined machine requires less area than two separate units plus connecting conveyors. Second, the integrated conveyor system ensures smooth product transfer from the sealer to the tunnel without manual handling or conveyor alignment issues.

Third, the synchronized operation means the sealing and shrinking cycles are perfectly timed, eliminating the timing mismatches that can occur with separate machines. Fourth, the single PLC control system simplifies operation, as the operator manages both functions from one interface. Finally, the integrated design typically costs less than purchasing separate machines, making it an economical choice for medium-volume packaging operations.

Frequently Asked Questions

What is the advantage of a combo machine over separate sealer and tunnel?

The ASS450-AI combo machine saves floor space (approximately 30-40% less than separate machines), eliminates conveyor alignment issues, ensures perfect synchronization between sealing and shrinking, simplifies operation with a single control interface, and typically costs 15-20% less than purchasing separate machines. However, if one component needs maintenance, the entire machine must stop. For very high-volume operations, separate machines may provide more flexibility and easier maintenance access.

What shrink films does the ASS450-AI support?

The ASS450-AI supports polyolefin (POF) shrink film, PVC shrink film, and PE shrink film. POF is recommended for most retail packaging due to its clarity, strength, and food-safe properties. PVC is economical for non-food applications. PE is used for heavier products. The sealer handles film thicknesses from 15 to 60 microns. The tunnel temperature should be adjusted based on film type: POF typically requires 150-180 degrees C, PVC 140-160 degrees C, and PE 160-200 degrees C.

What is the maximum product size the machine can handle?

The ASS450 sealer has a sealing width of 350mm and infinite sealing length, meaning products up to 350mm in width can be packaged. The BSD3520A tunnel has dimensions of 800x350x200mm (LxWxH), so the maximum product size is approximately 350mm in width and 200mm in height. The product length is limited by the tunnel length of 800mm. For products larger than these dimensions, we offer separate sealer and tunnel models with larger capacities.

How many packages can the machine produce per hour?

The ASS450-AI can produce approximately 900-1800 packages per hour, depending on product size, film type, and operator feeding speed. The conveyor speed of 15 m/min enables continuous product flow through the sealing and shrinking stations. For optimal throughput, products should be consistently spaced on the infeed conveyor. An automatic product feeding system can be integrated for fully automated operation to maximize throughput.

Does the machine require compressed air?

Yes, the ASS450 sealer component requires compressed air at 0.4-0.6 MPa with a flow rate of approximately 100L/min for the pneumatic L-bar sealing head. The BSD3520A tunnel component does not require compressed air. A standard industrial air compressor with a 50L tank is sufficient. The machine includes an integrated air filter, pressure regulator, and lubricator (FRL unit) for clean, stable air supply to the pneumatic sealing system.

Can the machine handle printed shrink film?

Yes, the ASS450-AI can handle printed shrink film with registration marks. The sealer includes a photoelectric sensor that detects the registration mark on the film and positions the seal cut precisely between printed designs. This ensures the printed graphics are properly positioned on each package without cutting through printed elements. For printed film applications, the film feeding speed and sensor sensitivity should be adjusted to match the film registration mark spacing.

What is the maintenance schedule?

Daily: Clean the L-bar sealing blade of film residue, check film supply, and wipe the conveyor belts. Weekly: Inspect the pneumatic system for air leaks, clean the photoelectric sensor, and lubricate the film feeding guide rails. Monthly: Check the sealing blade for wear, verify temperature controller accuracy, inspect the tunnel conveyor belt, and clean the tunnel interior of film residue. The non-stick coating on the sealing blade should be replaced when worn to prevent film sticking.
