DESCRIPTION:

BRIEF SUMMARY
The present invention relates to a method, wherein a tubular wrapping used as a package and consisting of an inner and outer film is produced in a packaging machine and an article to wrapped is sealed by means of air or some other gas to be blown into a space between the films included in the tube.
U.S. Pat. No. 4,918,904 discloses a wrapping method, wherein the package comprises a double bag having an opening on one side. When wrapping, an article must be inserted inside the bag through the opening. The wrapped article is fixed in the bag by means of air or other gas to be blown into a space between the films. This bag is poorly adaptable to automatic wrapping as the bag must be opened along the open side separately and in an individual operation. Bags of different sizes are required for articles of different sizes. Bags must be pre-designed and pre-produced for various products. Thus, this method is primarily suitable for manual wrapping and has a limited range of applications.
Prior known are also methods employing moulds and various foam plastics, such as expanded polystyrene or urethane, for producing a protective material for various products. This is an expensive method which also produces a lot of package material waste. An individual mould must be separately constructed for each product or article, which is a tedious and uneconomical solution. Packing an article in these protective materials requires a lot of manual labour and calls for a separate package storing facility and also intermediate storages for the actual packaging or wrapping materials.
An object of this invention is to provide a novel wrapping method which does not involve the above drawbacks.
Among the most important benefits offered by the invention are the facts that the method is extremely well adaptable to automated wrapping and that the method not only produces a package but also packages an article and that the inner and outer films can have different compositions, for example the inner film can be antistatic and the outer film non-antistatic or the inner film resistant to sharp objects and the outer film impervious to light and that, by replacing the mould, one and the same plastic material can be used for quickly producing packages of varying sizes in compliance with the production of articles in question and that the usable materials include environmentally friendly film materials. Since the tube is open at both ends thereof, the insertion of an article in the tube is easy by using automatics and since the inner film moulds itself around an article to be wrapped regardless of its shape, the article will be well protected against external impacts and the article to be wrapped remains immobilized in the package. Thus, this method is highly adaptable to the automated wrapping of articles of varying sizes and requiring various protective materials as a part of production regardless of the degree of automatization used in the production of articles to be wrapped.
This method reduces considerably the waste and recycling problem of spent packages if compared, for example, to foam-plastic based, article-protecting materials, such as expanded polystyrene or urethane, since an empty tube requires just a fraction of space if compared to the above foam-plastic based solutions or other solid-structure based solutions. The method also enables the elimination of moulds carefully designed for a particular article to be wrapped and solid materials used in a package. The demand for storage space is reduced as the package is produced as a result of the wrapping process and there is no need for producing empty packages.
Referring to what is described above, this method is more flexible, environmentally more friendly, quicker and more economical than the prior known solutions.
A method of the invention for producing a package and for wrapping an article will now be described in detail by way of an exemplary embodiment with reference made to the accompanying drawings.
