BS-4522N Shrink Wrap Heat Sealer Plastic Film Bag Automatic Internal Circulation Heating Packing Machine for Food Box

Product description

The BS-4522N Internal Circulation Heat Shrink Machine is a professional, energy-saving, and efficient packaging device designed for food boxes, gift boxes, bottles, cosmetics, stationery, electronics, and daily necessities. Adopting advanced internal circulation heating technology, it provides uniform, stable, and fast shrink wrapping with low energy consumption, making it widely used in food processing factories, packaging workshops, e-commerce warehouses, and assembly lines that require high-quality and high-efficiency packaging.

This machine uses 380V 50Hz three-phase power supply, ensuring stable power output for long-term continuous operation. It has a maximum load capacity of 20 kg, which is stronger than conventional models and can safely transport medium and heavy products without deformation or slipping. The heating tunnel measures L1300×W450×H220 mm, suitable for products within W300×H150 mm. The lengthened cavity provides sufficient heating time to achieve perfect shrinkage even for thick films and large-sized items. The conveying speed is adjustable from 0 to 10 meters per minute, allowing users to set the most suitable speed according to product material, film type, and production tempo, ensuring tight, wrinkle-free, and beautiful packaging.

The BS-4522N supports PVC, PP, POF and other common heat-shrink films, featuring strong compatibility and wide application. The internal circulation hot air system distributes heat evenly inside the tunnel, avoiding local overheating or insufficient shrinkage. This design greatly improves heat utilization, reduces power consumption, and achieves obvious energy-saving effects. The overall machine dimension is 176×77×143 cm, with a stable structure suitable for long-term placement in industrial workshops and production lines.

In terms of performance, the machine is equipped with an intelligent temperature control system that keeps the temperature stable and accurate, ensuring consistent shrink effect in mass production. The conveyor runs smoothly with low noise, no jamming, and no deviation, improving product stability during transmission. The operation panel is simple and intuitive; temperature and speed can be adjusted easily, enabling workers to master operation quickly without professional training, greatly improving packaging efficiency and reducing labor costs.

Durability and safety are fully considered in the design. The machine is made of high-strength metal materials with high temperature resistance and long service life. It is equipped with over-temperature protection, emergency stop, leakage protection, and overload protection functions to ensure safe and reliable operation during long hours of work. The internal structure is easy to clean and maintain, adapting to high-frequency daily use. Low failure rate and low energy consumption effectively reduce long-term operating costs and bring economic benefits to enterprises.

The internal circulation design makes this machine more efficient in heat utilization and more uniform in shrinkage, especially suitable for food boxes and regular-shaped products that require neat appearance. It can achieve transparent, flat, and tight packaging, enhancing product aesthetics, sealing, dustproofing, and moistureproofing performance. It is widely used in food boxes, gift boxes, bottled drinks, cosmetics sets, electronic products, stationery, and other industries.

Compared with traditional shrink machines, the BS-4522N has obvious advantages: more uniform heating, higher energy efficiency, larger load capacity, and more stable performance. It is an ideal choice for enterprises pursuing energy saving, high efficiency, and high-quality packaging.

In summary, the BS-4522N Internal Circulation Heat Shrink Machine is a reliable, efficient, and energy-saving industrial packaging equipment. With internal circulation technology, strong load capacity, wide film compatibility, stable conveying, and safe structure, it becomes the preferred equipment for medium and high-speed production lines. It helps enterprises improve packaging efficiency, optimize product appearance, ensure packaging quality, and provide stable and professional packaging support for various industries.
