Shanghai KUKO Packing Machinery Co., Ltd. designs and builds POF Film Shrink Wrapping Machine supplier systems that produce clear, tight, low-temperature polyolefin packaging for single products, multi-pack groups and retail displays. Our POF line is part of a broader Shrink Wrapping Machine family covering low-, medium- and high-speed series, with more than 200 models engineered for 24/7 continuous production.
POF film shrink wrapping machine range and positioning
As a POF Film Shrink Wrapping Machine manufacturer based in Shanghai, China, we supply both standalone sealing-and-shrink systems and machines prepared for automatic line integration. The range is positioned around two proven platforms, supported by the same sealing, heating and control technology used across our fully automatic shrink wrapping equipment.
SF-4525
Long-lasting, durable heat shrink packaging machine for compact product formats. Suited to cartons, boxes, electronics accessories and single-pack applications.
SF-4525 details
SF-5030LG
Premium heat shrink packaging machine for medium-size products and grouped packs where film clarity, seal strength and output stability matter.
SF-5030LG details
Application fit: products and materials suited to POF
POF film gives a glossy, transparent finish with good puncture resistance and a lower shrink temperature than PVC or PE. That makes it attractive for food and beverage, pharmaceutical, daily chemical, electronics and logistics applications where heat sensitivity or product appearance is a concern.
Typical workpieces include:
- Cartons and boxes, single or multi-packs
- Bottles, cans, jars and irregular containers
- Books, stationery, printed materials and media
- Electronic components, 3C accessories and small appliances
- Pharmaceutical boxes and medical consumables

Configuration, controls and automation integration
We configure each POF machine around the working point, not the other way round. The proposal is based on product dimensions, pack weight, film specification and line speed, and the machine is built with the sealing frame, tunnel length and conveyor arrangement to match.
- Sealing: Temperature-controlled sealing bars with adjustable dwell and pressure for clean, pinhole-free seams.
- Shrink tunnel: Circulating hot air with adjustable temperature, conveyor speed and air distribution; vent-hole patterns are set to evacuate air without distorting the film.
- Controls: PLC-based operation with clear changeover settings; machines can be prepared for MES integration and line signal handshaking.
- Conveying: Infeed, spacing, outfeed and cooling sections can be added to create a continuous flow from cartoner to pallet.
- Auxiliary equipment: Space and bracketry can be arranged for date coding, labeling or inspection before or after the shrink process.
Engineering precision and quality assurance
Our two production bases in Kunshan Zhouzhuang and Shanghai Sheshan give us a total workshop area of 34,000 square meters. We use German IPG high-precision laser cutters and imported high-accuracy servo bending machines for sheet metal fabrication, which keeps frame and guarding tolerances consistent across the machine range.
We are ISO9001 certified and hold EU CE conformity for our heat shrink packaging machines. All machines are built for continuous operation and are adjusted and test-run before release, with the electrical and mechanical documentation needed for installation and acceptance. Our equipment is used in food, daily chemical, electronics, logistics, pharmaceutical and furniture production, including installations for P&G, Johnson & Johnson, L'Oreal, JD.com, SF Express, CATL and Mars Group.
Installation, acceptance and service scope
Each project includes the machine, guarding, operator documentation and the film and format parameters agreed during configuration. We provide a one-year warranty and life-cycle maintenance support, and our service engineers can commission the machine and train line operators as part of the delivery scope.
Maintenance is concentrated on the sealing bar insulation, film feeding rolls, conveyor chain and tunnel fans. Spare parts and consumable kits are available through our Shanghai production base.
Information We Use to Configure Your Solution
To prepare a precise POF shrink wrapping proposal, we use the following project data:
- Product dimensions, weight and material
- Pack pattern: single, multi-pack, tray or display pack
- Target output per minute and shift pattern
- POF film type, reel width and thickness, if already selected
- Current line layout and conveyor height
- Electrical supply, voltage and frequency
- Regulatory or customer-specific documentation requirements
POF Film Shrink Wrapping Machine FAQs
Can POF film be used for food and pharmaceutical packaging?
Yes. POF has a low shrink temperature, good clarity and is widely used for food, beverage and pharmaceutical packs. Our machines are configured with the tunnel temperatures and seal settings needed for heat-sensitive products.
What information is needed for a quotation?
Send us the product dimensions, pack weight, film specification if known, target speed, electrical supply and the current layout of the line. We use this data to define the sealing frame, tunnel configuration and conveyor arrangement.
Can a POF shrink wrapping machine be integrated into an existing line?
Yes. We can add infeed and outfeed conveyors, spacing guides, and control signal interfacing to upstream fillers, cartoners or labeling machines. MES connectivity is available for machines operating as part of a larger automated line.
How is sealing quality controlled for soft or irregular products?
The sealing bar temperature, dwell time and pressure are adjusted to the product, and the tunnel airflow and conveyor speed are set to avoid crushing. Vent-hole patterns are arranged to prevent trapped air and dog ears.
What support is provided after delivery?
All equipment comes with a one-year warranty and life-cycle maintenance support. Spare parts, sealing bar consumables and film guides can be supplied from our Shanghai production base.
Which certifications apply to KUKO shrink wrapping machines?
Our machines are manufactured under an ISO9001 quality management system and CE certified for the EU market. We also hold recognition as a Shanghai High-Tech Enterprise and a Specialized and Sophisticated Enterprise.
