Sleeve Sealer & Shrink Tunnel

A Sleeve Sealer and Shrink Tunnel is a versatile shrink wrapper for large products, offering numerous benefits for businesses aiming to enhance their packaging efficiency. These systems are a crucial part of any modern packaging line, serving as reliable shrink wrappers that ensure precision and speed in wrapping. Our automatic sleeve shrink wrapping machines seamlessly feed, transport, seal, and shrink products. Compatible with various shrinkable materials such as PE and POF films, our industrial shrink wrap machines and shrink film wrapping machines cater to diverse packaging standards and purposes. These heat shrink wrapping machines deliver high-standard packaging that is waterproof, dustproof, transparent or customized in design, and impeccably neat.

The versatility of a sleeve sealer makes it an ideal solution for shrink-wrapping a wide range of products using shrink film. This type of shrink wrapping machine is commonly used for packaging bottles and jars, including those for cosmetics, beverages, or food, as well as boxes, cartons, pallets, and cases. Sleeve sealers are particularly well-suited as shrink wrappers for multipacks of bottles or cans, electronic devices and accessories, and household products like cleaning supplies and toiletries. These machines are also effective for shrink wrapping health and wellness products, various consumer goods, and promotional items.

In addition to their broad applications, these systems are highly compatible with different types of shrink wrap equipment, ensuring seamless integration into production lines. Whether used as a shrink packing machine or customized as a shrink packaging machine, sleeve sealers combined with a shrink tunnel provide reliable and efficient solutions for single products or multipacks.

Investing in our high-speed sleeve sealer and shrink tunnel offers numerous advantages:

• Superior Packing Quality: Product-sensing horizontal and vertical eyes, along with time relays, ensure consistent film applications and prevent product movement, tampering, or damage during transit.
• Precision Control: Operators can precisely manage angular and linear positions, as well as packaging velocity, ensuring high accuracy.
• High Wrapping Speed: Achieve wrapping speeds of up to 28 collations per minute (1,680 per hour), depending on pack size.
• Modular Design: Easily integrate with existing lines, featuring automatic temperature control, alignment, adjustable feeding sensors, and precision lock-up sleeves for enhanced efficiency.
• Adjustable Conveyor Speeds: Infeed and dispatch conveyors can be adjusted through a variable speed drive system.
• Automatic Cool Down Cycle: Ensures packaging is cooled efficiently post-sealing.
• Adjustable Sealing Plate: Guarantees clean sealing lines and smooth cuts without film cracking or sticking. Sealing temperature is fully adjustable.
• User-Friendly Interface: Bilingual PLC touch screens and HMI control technology optimize coordination between servo motors and photo-electric sensors, enhancing sleeving accuracy and efficiency.
• Durable Construction: Stainless-steel frames with safety guards protect operators and ensure longevity.
• Easy Product Changeovers: Precise coordination between modules facilitates quick and easy changes between different products.
• Consistent Seals at High Speeds: Heavy-duty, height-adjustable sealing jaws maintain strong seals even at high operational speeds.
• Integrated Programming: Allows for single to multi-row packaging without the need for separate molds.
• Automatic Pack Counting: Enhances production volume tracking and statistics.
• Cost Efficiency: Integrating a shrink tunnel reduces time and labor expenses, significantly boosting production efficiency.

Our automatic sleeve sealer and shrink tunnels are engineered for high production volumes, making them ideal for display, transportation, and distribution purposes. Here’s how the process works:

1. Product Feeding: Products are fed onto an inverter-driven, heat-resistant mesh belt conveyor.
2. Alignment and Stability: Smart photo-electric sensors detect product instabilities and relay information to an onboard micro-controller, ensuring products remain aligned as they move towards the sealing chamber.
3. Sealing Chamber: The sealing station houses top and bottom film roll holders that create a curtain of PE, PVC, BOPP, or POF shrink film at the chamber’s entrance. Products pass through this film curtain.
4. Sleeve Formation: A two-way vertical drive system forms sleeves around the products. With the help of product pack clamps, sleeves can be configured in long, single or multi-row, or collated tray formats, resulting in two small openings on opposite sides of the wrapped products.
5. Consistent Wrapping: Product-sensing horizontal and vertical eyes, combined with time relays and an adjustable sealing blade, ensure neat and durable wrapping that prevents in-transit movement and product tampering.
6. Final Shrink Wrapping: Additional packaging components such as guides, pad-feeding magazines, dye-cut cardboard sheets, and stacking mechanisms can be incorporated before the packaging enters the shrink tunnel for final shrink wrapping.
