Shanghai KUKO Packing Machinery Co., Ltd. designs and builds continuous sleeve sealing and heat-shrink wrapping systems in Shanghai, China. As a Fully-auto Sleeve Sealing Shrink Wrapping Machine manufacturer, we supply low-, medium- and high-speed models from a portfolio of more than 200 packaging machines. These systems are used for single-pack and multi-pack wrapping of bottles, cans, cartons, rolls, coils and irregular products in food, beverage, daily chemical, pharmaceutical, electronics, logistics and furniture production.
In the Sleeve Sealing Shrink Wrapping Machine family, the fully automatic category is the right choice when manual film loading and sealing become bottlenecks. The machine forms a heat-shrinkable sleeve around the product, seals it accurately, and sends the pack through a temperature-controlled shrink tunnel. The result is a tight, dust-resistant and tamper-evident package that also stabilises multi-item sets before secondary packing.
Product Range and Application Fit
Our fully automatic sleeve sealing range is organised around the physical shape of the product, the number of packs per minute, and the space available in the line. Each layout uses the same core sealing and shrinking principle, but the film path, sealing frame and tunnel dimensions are configured for the application.
| Configuration |
Layout |
Typical Use |
| Column type |
Compact vertical film holder beside the sealing station |
Bottles, jars, cans and multi-packs on existing conveyor lines |
| Integral type |
Sealer and shrink tunnel combined in one frame |
Medium-speed production where floor space is limited |
| Multi-layers / multi-rows |
Multiple sealing heads or multiple lanes in one system |
Large grouped bundles and small consumer goods needing high unit output |
| For tapes / round wire |
Dedicated guides and sealing stations for cylindrical coils and adhesive tape rolls |
Masking tape rolls, adhesive tapes, wire coils and wound products |
| Motion / straight servo |
Servo film feed and continuous sealing for high-output lines |
Regular cartons and high-speed lines requiring precise film control |
| Vertical linear / circle type |
Vertical sleeve placement for long profiles or circular products |
Extrusions, profiles, circular parts and products needing 360-degree cover |
| Luggage shrink wrapper |
Oversized sealing and tunnel opening |
Luggage, large household items and industrial components |
For example, the column-type sealer and shrink tunnel is a common starting point for beverage and daily chemical lines because it fits beside existing conveyors without a major layout change. Multi-row and multi-layer systems are specified when a single wrapping point must handle several product streams or stacked groupings in one cycle.
Engineering and Configuration Approach
We size the sealing station and shrink tunnel around three inputs: product envelope, bundle pattern and target throughput. The fully automatic control system manages film feeding, sealing dwell, film cutting and tunnel conveyor speed so that each pack receives the same seal position and shrink quality. Typical configuration details we define during engineering include:
- Sealing width and height range, including motorised or tool-less adjustment for format changeover
- Shrink tunnel temperature zones, air circulation direction and conveyor speed settings for the selected film
- Infeed and outfeed conveyor heights matched to your existing line
- Photoelectric registration for printed film, tear tape or perforated sleeve material
- Protective guarding, emergency stops and interlocked access panels designed to CE principles
Line Integration and Control
Fully automatic sleeve wrappers are built for continuous operation rather than occasional use. Our machines are engineered for 24/7 stable running and can be connected to MES systems for cycle counts, fault reporting and line status monitoring. The control platform is selected according to the interface required by your factory, and the machine can be supplied with indexing conveyors, spacing belts, diverters or integration to labelers and cartoners.
After the shrink stage, many customers protect the unit load before shipment. We also manufacture the Fully-auto Pallet Stretch Wrapping Machine, so the same supplier can provide wrapping, shrinking and pallet-level protection as one coordinated end-of-line system.
Quality Assurance and Manufacturing Backing
KUKO operates two production bases in Kunshan Zhouzhuang Industrial Park and Shanghai Sheshan Industrial Park, with a total workshop area of 34,000 square metres. Our fabrication uses German IPG high-precision laser cutters and imported servo bending machines, giving us consistent sheet-metal accuracy across standard and non-standard machines. The company holds ISO9001 quality management certification and EU CE certification, and is recognised as a Shanghai High-Tech Enterprise and a Specialized and Sophisticated Enterprise.
Before despatch, each machine is assembled, mechanically aligned and run through a pre-delivery test sequence. We confirm seal strength, film shrinkage, conveyor synchronisation and electrical safety, then release the machine for export packing. Documentation supplied with the machine includes operating and maintenance instructions, electrical drawings and the relevant CE declaration for the configuration delivered.

Frequently Asked Questions
What is the difference between fully automatic and semi-automatic sleeve sealing machines?
Fully automatic models feed the film, form the sleeve, seal and shrink without an operator placing material on each product. Semi-automatic machines use the same sealing and shrinking principle but require manual loading or manual film positioning. We supply both categories within the Sleeve Sealing Shrink Wrapping Machine family.
Which films can be used on these machines?
The systems are configured for heat-shrinkable films such as POF, PVC and PE. Tunnel temperature, air volume and conveyor speed are adjusted according to film formulation, thickness and shrink ratio, so we need film samples or specifications before final machine settings are confirmed.
Can the machine be connected to an MES or an existing production line?
Yes. The control system can exchange operating data with MES platforms, and the machine can be integrated with existing conveyors, labelers, cartoners and inspection systems. We confirm the communication protocol and data points during project engineering.
What information do you need to prepare a proposal?
We need product dimensions, bundle pattern, target speed, film details, available floor space and utility conditions. With these inputs, we specify the sealing width, tunnel length, conveyor height and control interface needed for your line.
What after-sales support do you provide?
Our equipment is covered by a one-year free warranty and lifetime maintenance support. Spare parts for normal wear items such as sealing wires, heat-resistant cloth and conveyor belts are available, and we provide the documentation needed for your maintenance team to operate the machine safely.
