BSD450B

BSD450B Heavy Duty Shrink Tunnel Machine – Large Capacity Shrink Oven

Product Description

The SunAura BSD450B is a heavy-duty shrink tunnel machine designed for large-capacity shrink wrapping applications. As the largest model in the BSD series, the BSD450 features an 8 KW heating system and a maximum load capacity of 10 KG, making it suitable for packaging heavier and larger products that exceed the capacity of the BSD400 model. The machine uses hot air circulation technology to shrink film tightly around pre-sealed products, creating professional, secure packages for retail display and distribution.

The BSD450B features the same adjustable conveyor speed (0-10 m/min) and maximum temperature (200 degrees C) as other BSD models, but with a larger tunnel chamber and more powerful heating system. The 8 KW heating capacity ensures rapid temperature recovery when heavy products enter the tunnel, maintaining consistent shrink quality even during continuous high-load operation. The machine is compatible with POF, PVC, and PE shrink films, and the insulated double-wall housing provides energy efficiency and operator safety.

Applications of BSD450B Shrink Tunnel

• Heavy Product Packaging: Shrink wrapping for heavy multipacks, bulk product bundles, and industrial product packages weighing up to 10 KG. The reinforced conveyor and powerful heating system handle heavy loads with ease.
• Beverage Multipacks: Shrinking film around beverage 6-packs, 12-packs, and 24-packs. The large tunnel accommodates multipack dimensions and the 8 KW heating system ensures complete shrink around heavy liquid containers.
• Industrial Products: Shrink wrapping industrial components, hardware kits, and mechanical parts for corrosion protection and secure packaging during storage and shipping.
• Food Bulk Packaging: Packaging bulk food products, canned goods multipacks, and large food gift sets. The stainless steel interior meets food packaging standards.
• Building Materials: Shrink wrapping building material samples, tile bundles, and construction product packages for retail display and protection.
• Large Gift Sets: Packaging premium gift sets, holiday bundles, and corporate gift packages in professional shrink film for premium retail presentation.

BSD450 vs BSD400: When to Upgrade

The BSD450 offers two key advantages over the BSD400: higher heating power (8 KW vs 6.5 KW) and higher load capacity (10 KG vs 5 KG). The 8 KW heating system provides faster temperature recovery when products enter the tunnel, which is critical for continuous high-volume operation where the tunnel temperature would otherwise drop when processing heavy products. The 10 KG load capacity allows packaging of heavier multipacks and industrial products.

Consider upgrading to the BSD450 when your products weigh more than 5 KG, when you process heavy products continuously and experience temperature drops with the BSD400, or when you plan to package larger multipacks in the future. The BSD450 is also recommended for operations using PE shrink film, which requires higher shrink temperatures and more heating power than POF or PVC films.

Frequently Asked Questions

What is the difference between BSD450B and BSD400B?

The BSD450B has an 8 KW heating system (vs 6.5 KW on BSD400B) and a 10 KG maximum load capacity (vs 5 KG on BSD400B). The BSD450B also has a larger tunnel chamber to accommodate bigger products. Both models share the same conveyor speed range (0-10 m/min), maximum temperature (200 degrees C), and film compatibility (POF, PVC, PE). Choose the BSD450B for products over 5 KG or for high-volume continuous operation where faster temperature recovery is needed.

What is the maximum product weight the machine can handle?

The BSD450B can handle products weighing up to 10 KG. This is double the capacity of the BSD200, BSD350, and BSD400 models (all 5 KG). The reinforced conveyor belt and heavy-duty tunnel construction support the higher load capacity. For products exceeding 10 KG, we offer custom heavy-duty shrink tunnel models with extended conveyor reinforcement and additional heating capacity. contact us with your product weight and dimensions for a recommendation.

How fast does the tunnel recover temperature after products enter?

The BSD450B 8 KW heating system provides rapid temperature recovery compared to the 6.5 KW BSD400 model. When a heavy product enters the tunnel, the temperature typically drops 5-15 degrees C. The 8 KW heating system recovers this temperature drop within 3-5 seconds, maintaining consistent shrink quality. For continuous operation with heavy products, the BSD450B maintains more stable tunnel temperature than lower-power models, ensuring uniform shrink results across all packages.

Can the machine handle PE shrink film?

Yes, the BSD450B is well-suited for PE (polyethylene) shrink film, which requires higher shrink temperatures (160-200 degrees C) than POF or PVC films. The 8 KW heating system provides sufficient power to maintain the high temperatures required for PE film shrink, even during continuous operation. PE film is typically used for heavier products and industrial applications due to its thickness and strength. The BSD450B is the recommended BSD model for PE film applications due to its superior heating capacity.

What are the tunnel dimensions?

The BSD450 model features a larger tunnel chamber than the BSD400 model. The exact tunnel dimensions depend on the specific configuration, but the BSD450 typically has a tunnel length of 1000-1200mm, width of 450mm, and height of 250mm. The larger tunnel accommodates wider and taller products than the BSD400. For specific tunnel dimension requirements, please contact us with your product dimensions and we will confirm compatibility or recommend a custom configuration.

Does the machine require a separate sealer?

Yes, the BSD450B is a shrink tunnel only and requires a separate L-bar sealer (such as our FQL450LA) to cut and seal the shrink film before products enter the tunnel. For operations that prefer an integrated solution, we offer the ASS450-AI combo machine that combines a sealer and tunnel in one unit. However, for heavy products requiring the BSD450 tunnel capacity, a separate sealer and tunnel configuration provides more flexibility and easier maintenance access.

What is the power consumption during continuous operation?

The BSD450B has a power rating of 8 KW. During continuous operation, the heating elements cycle on and off to maintain the set temperature, resulting in average power consumption of approximately 4-5 KW. The actual consumption depends on the set temperature, product throughput, and ambient temperature. The insulated double-wall tunnel housing minimizes heat loss, improving energy efficiency. For facilities with limited power capacity, the machine can be configured for 380V three-phase power to distribute the load.
