A Dedicated Shrink Sleeve Tunnel Manufacturer

Shanghai KUKO Packing Machinery Co., Ltd. is a China-based shrink sleeve tunnel manufacturer and heat shrink packaging line integrator. Founded in 2004 and headquartered in Songjiang District, Shanghai, we design and build fully automatic sleeve labeling and heat shrink packaging equipment, including sealing stations, heat shrink tunnels, pallet wrapping systems, and end-of-line film wrapping machines.

This Shrink Sleeve Tunnel Manufacturers category represents the core of our output: over 200 models arranged in low-, medium-, and high-speed series. The equipment is engineered for 24/7 continuous operation and can be connected to MES systems, making the range suitable for production plants that need stable, repeatable packaging with measurable line data.

Our Product Range in This Category

We supply complete sealer-and-tunnel systems, not just heating tunnels. The four product families below cover the full shrink wrapping workflow from product infeed to palletized load.

Fully Closed Sealing and Shrink Wrapping Machine

This family integrates film feeding, wrapping, sealing and cutting, and hot-air shrinking in one automated system. The fully enclosed tunnel structure reduces heat loss and prevents film debris from entering the workshop. It is the main choice for mass production in food, daily chemical, hardware, and logistics environments.

Fully automatic versions include side seal, double side, corner seal, motion, rear blade, vertical L-bar, and mix production layouts.
Semi-automatic versions include L-bar and corner seal stations for small-batch or changeover-heavy lines.

Sleeve Sealing Shrink Wrapping Machine

For products that need full sleeve coverage or tamper-evident bundling, this family uses a sleeve of shrink film placed around bottles, jars, cans, or grouped containers before entering the shrink tunnel. Column-type, integral-type, and multi-layer configurations match different bottle shapes and line speeds.

Fully-auto Pallet Stretch Wrapping Machine

This family covers cold stretch hooding and pallet shrink wrapping. Cold stretch hooding applies a five-sided elastic hood for load stabilization in warehousing and transport; pallet shrink wrapping provides a tight, weather-resistant cover for outdoor storage or export.

Fully-auto Film Wrapping Equipment

Fully automatic film wrapping machines combine static sealing and shrink wrapping for high-volume end-of-line applications. They are used when a single machine must handle a continuous product flow without operator intervention.

Application Fit and Selection Variables

The right configuration depends on product shape, film type, line speed, and the degree of automation already present on the line. The table below summarizes the fit of each product family.

Product Family	Typical Applications	Configuration Focus
Fully Closed Sealing and Shrink Wrapping Machine	Single items, trays, cartons, and multi-packs in food, beverage, daily chemical, electronics, and hardware lines	L-bar, side seal, corner seal, double-side, motion, and vertical L-bar; fully-auto or semi-auto loading
Sleeve Sealing Shrink Wrapping Machine	Bottles, jars, cans, and grouped containers requiring full sleeve coverage or bundling	Column-type, integral-type, and multi-layer sleeve sealers matched to a shrink tunnel
Fully-auto Pallet Stretch Wrapping Machine	Palletized bags, cartons, drums, and finished goods in warehousing and logistics	Cold stretch hooding or heat-shrink pallet hood for load stabilization and weather protection
Fully-auto Film Wrapping Equipment	High-volume lines where static sealing and shrink wrapping must run without operator intervention	Fully automatic film feed, sealing, tunnel, and line interface

Engineering and Line Integration Value

Because we build the equipment in our own factory, we control the mechanical precision, thermal design, and control interface of the complete system. Our two production bases in Kunshan Zhouzhuang Industrial Park and Shanghai Sheshan Industrial Park total 34,000 square meters of workshop space, allowing us to run standardized production and custom projects on the same site.

Sheet metal fabrication uses German IPG high-precision laser cutting machines and imported high-accuracy servo bending machines for accurate tunnel bodies, sealing frames, and conveyor sections.
Closed tunnel design with stable temperature control and balanced air flow gives consistent film shrinkage and protects products from dust, moisture, and impact.
Intelligent sensing controls material infeed, sealing, and shrink parameters, reducing the need for constant supervision.
MES integration allows packaging data to flow into production management systems.
We also supply non-standard conveyor lines and end-of-line integration, including connections to existing upstream and downstream equipment.

Quality Control and Compliance

KUKO is ISO9001 quality management system certified and holds EU CE certificates for heat shrink packaging machines and conveyors. The company is recognized as a Shanghai High-Tech Enterprise and a Specialized and Sophisticated Enterprise, with numerous invention and utility model patents supporting the mechanical design and control methods used in these machines.

Our in-house manufacturing chain covers precision sheet metal processing, assembly, and final testing. This vertical structure allows us to maintain consistent quality across the sealing section, tunnel, and conveyors before equipment leaves the factory.

Information We Use to Configure Your Solution

Our proposal is based on the working point, material, and production target. Send us the following data so the sealer and shrink tunnel can be matched to your line:

Product dimensions, weight, and shape, including fragile or heat-sensitive areas.
Film type and thickness currently used or planned: POF, PVC, PE, or other shrink films.
Target throughput in packages per minute and the number of operating shifts.
Packaging pattern: single product, multi-pack, tray, carton, or palletized load.
Existing line height, conveyor type, available floor space, and desired infeed and outfeed direction.
Required automation level: manual loading, semi-automatic, fully automatic, or MES-connected.
Compliance or market-specific requirements such as CE marking or material contact needs.

Operation and Maintenance Considerations

These machines are designed for continuous operation with straightforward routine maintenance. The main service points are the sealing and cutting station and the oven chamber.

Clean the sealing bars, silicone pads, and sealing base regularly to maintain seal strength.
Remove film residue from the oven chamber and check thermal sensors and fan airflow.
Inspect wiring, transmission components, and conveyor belts periodically.
Place the machine on a level floor and keep personnel clear of the high-temperature tunnel body during operation.

All equipment is supplied with a one-year free warranty and life-cycle maintenance support. Our service package also includes troubleshooting guidance for common film defects such as swelling, hazing, fish eyes, fishtail wrinkles, dog ears, and crushed product corners.

Frequently Asked Questions

What is the difference between a fully closed sealing machine and a sleeve sealing machine?

The fully closed sealing and shrink wrapping machine cuts and seals flat film around the product before shrinking, while the sleeve sealing machine draws a sleeve of film over the product and then shrinks it. Flat-film sealers are flexible for many product shapes; sleeve sealers are often a better fit for bottles, jars, and multi-packs that need full coverage.

Which shrink films can these tunnels handle?

Our tunnels work with standard POF, PVC, and PE shrink films. Temperature, airflow, and conveyor speed are adjusted according to the film type and the product's heat sensitivity, so we normally confirm the film specification during project review.

Can the tunnel be integrated with our existing conveyor and MES system?

Yes. We configure the infeed and outfeed height, conveyor direction, and control interface to match your line. MES integration is available so packaging data can be collected and monitored centrally.

How do you size a shrink tunnel for our product?

We need product dimensions, film type, target line speed, and any heat-sensitive product areas. The typical proposal then specifies tunnel temperature, airflow, dwell time, and sealing configuration needed to achieve that throughput.

What maintenance is required on the sealing and shrink tunnel?

Routine maintenance is limited to cleaning the sealing bars and oven chamber, checking conveyor and transmission components, and watching for film defects that indicate a temperature or airflow adjustment. We provide troubleshooting guidance and life-cycle support.
