Secondary Packaging Why do products need to be protected? Species vary over time, evolving from simpler forms into more and more complex forms, thanks to a mechanism of natural selection that favors the survival of those individuals best suited to the environment in which they live. Charles Darwin (synthesis of the concept expressed in “The Origin of Species by Means of Natural Selection”, 1859) ver recent years, the evolution of distribution platforms has globally triggered a process of reciprocal interference between consumer habits and packaging technologies. This interaction may be seen mainly...

OCME Secondary packaging The Bundle, history and technology undamentally, two types of technology may be used to create a bundle using heat shrink film: the sealing bar shrink wrapping machine or the continuous shrink wrapping machine. Sealing bar technology uses film originating from two reels that is laminated together and wrapped around a bundle of containers. The film is sealed using a bar/counterbar sealing unit containing a heating element that is activated to cut and seal the film around the pack. The pack then enters the oven where the film is heat shrunk. However, this type of technology...

Picture 5 Pack film wrapping and shrinking scheme. Picture 6 Detail of film wrapping belt on a Vega HT. containers transit over the front end of the film itself. As the pack advances with the front edge underneath it, a rotating bar accompanies the film, wrapping it around the pack until the rear end of the film is underneath the front of the bundle. In this way, the pack with the film enters the oven with the 2 ends overlapping underneath it: the hot air and the weight of the pack itself ensure that the two ends are welded together, guaranteeing pack stability and leaving the other sides of...

OCME Secondary packaging Vega HT, the fruit of over 25 years of packaging with heat shrink film he advent of the heat shrunk bundle revolutionized the approach of consumers and distributors towards many products. In 1986, OCME began developing this technology with a degree of flexibility never before reached. Vega HT is the result of a process that has optimized the solutions to concrete problems in bundle packaging: handling thinner films and lighter bottles, simultaneously guarantying complete adaptability to any type of format, fast format changes and low energy consumption. The novelties...

The forced ventilation oven allows for rapid and uniform temperature control: thanks to the care given to oven insulation and heating element temperature regulation. The heating elements are oversized, in order to reach the operating temperature quickly. Significant improvements have also been made in terms of energy savings. The latest generation of Vega HT heat shrink ovens consumes 30% less than the previous model. Flow control channels the hot air only where it is needed: pipes made of a heatresistant material channel the hot air incoming from the fan-heating unit to the side blowers to heat...

OCME Secondary packaging Vega HT in detail The Vega HTV shown in the these pages is a flexible machine, able to produce film only packs, pad and film packs, tray and film or tray only packs. This machine has been equipped with optional items designed to reduce the changeover time and improve the handling of containers, such as the centralized adjustment of infeed guides and the electronic selection of containers. Container infeed It is of fundamental importance that the infeed be shaped in such a way that the containers do not jam. Therefore, Vega HT has been equipped with solutions that render...

Brushless Plug & Play Glue group: it can also be Operator panel touch screen: Film wrap group, it is easily servomotor to avoid all the operations of mechanical re-phasing it can be moved along the machine frame and it is equipped with a USB slot for data storage accessible and requires a few minutes for the replacement of the carpet The Vega HT is fitted with total-vision guards for complete control of all machine components and the machine may be easily inspected even while it is running. The operator side is easily accessible as it is absolutely obstacle-free. The operator panel may be shifted...

OCME Secondary packaging 9 Reel unwinding OCME has designed various systems to feed the film to the cutting unit without tugging it and at the speed requested by the machine, adopting the various solutions based on the speed ranges. For output speeds up to 60 cycles/minute, the spindle on which the reel is fitted is controlled by a hydraulic brake, but to handle thinner films the reel may be unwound by a brushless motor that subjects the film to less strain. The standard solution for outputs of over 60 cycles/minutes is reel unwinding controlled by brushless motors. 10 Reel sealing Whether manual...
