Key Features:

L-shaped Sealing and Cutting Integration: Utilizing a classic L-shaped sealing and cutting structure, the machine automatically feeds the product into the shrink oven after sealing and cutting, completing the heat shrinking process seamlessly.

Multi-functional Sliding Film Carrier: Equipped with an adjustable sliding bracket, it can accommodate various sizes of heat shrink film. Combined with the perforation device, it operates smoothly to meet different packaging needs.

Convenient Height Adjustment: Featuring a handwheel adjustment mechanism, the conveyor belt height can be flexibly adjusted, easily calibrating the sealing and cutting position to ensure a centered and neat seal.

Precise Sealing and Cutting Control: Utilizing a time relay to control sealing and cutting time, parameters can be finely adjusted, resulting in stable and uniform sealing and cutting effects.

Rich Optional Functions: A pressing device can be added as needed, and imported horizontal and vertical detection sensors can be selected for precise sealing and cutting even for thin and small items.

Safe Anti-Mis-Cutting Design: The cutter has an automatic protection function, effectively avoiding the risk of accidental cutting and improving operational safety.

Durable Sealing and Cutting Blades: The sealing blade is made of alloy steel and coated with DuPont Teflon non-stick coating, which is high-temperature resistant, does not easily stick to the film, and will not cause problems such as edge cracking, charring, or smoke during operation, making it environmentally friendly and pollution-free.

High-Quality Core Components: The machine uses multiple internationally renowned brand components, ensuring reliable performance of the temperature control, transmission, and electrical systems, stable equipment operation, and a long service life.

Temperature-Controlled Shrink Tunnel: The shrink oven has precise temperature control, allowing the heat shrink film to adhere tightly to the product, providing dustproof, moisture-proof, and wear-resistant protection.

Applications: Widely used in packaging food, daily chemical products, cosmetics, small electronic products, gift boxes, general merchandise, and small industrial parts. It is especially suitable for bulk packaging of various regular boxed, bottled, and small combination goods, and is a cost-effective packaging choice for stores, small processing plants, and small and medium-sized production lines.
