TECMI EV 850-50 Film Shrink Wrapper
The EV 850-50 is an automatic continuous wrapping machine that can be used with shrink-wrap film on its own or film combined with a cardboard pad. It works up to a speed of 50 to 100 ppm, depending on whether a double or single lane machine is used, and it has a continuous linear movement. It doesn’t require a welding bar for sealing.
Available in a variety of configurations:
Pad + Film
Tray + Film
Dual Lane Bundling

The basic equipment for the standard 850.50 automatic wrapping machine incorporates a product input conveyor belt with low-friction coefficient thermoplastic chains. Designed for automatic pack preparation, it monitors lines to check when they are full and whether the product remains available.
The EV 850-50 has been manufactured according to a bottle grouping system that features a double set of electronically synchronized pneumatic barriers that allows format changes to be achieved easily. There is excellent product visibility and accessibility during all the stages of the process, which also simplifies the maintenance operation.
The film used for shrink-wrapping is cut with a rotating blade. There is a loading station for a spare reel that is monitored electronically so that there is constant tension while the reel unwinds. A manually operated welding bar is incorporated for joining film when it comes to the end of the reel.
This versatile automatic continuous wrapping machine also features an electronic system for monitoring pack formation. There are protection devices in the form of polycarbonate gates where the wrapping bar is. A two-stage reverse motion releases any bottles that are blocked under dragging bars.
There is also a programmable logic controller (PLC) and operative console that has command operations guidance for production speed, the length of polyethylene and so on. It also controls stop messages that come into play when the polyethylene reel ends, when there are emergency stops, or when there is a lack of air pressure.
The machine incorporates automatic placement of a cardboard pad under the pack whether there is a single or double lane, and the client chooses whether the command panel is on the left or right side.
The TECMI EV 850.50 system is set in place lengthways and feeding of product is achieved through the lower part of the machine. It has ample loading capacity and can accommodate different sizes.
Additionally, there is a pneumatic system that incorporates conveyor belts that lift the product onto a vacuum table to avoid the formation of wrinkles during the packaging product.
