ABSTRACT:
DESCRIPTION OF THE INVENTION
The present invention relates to a packaging wrapper or container and a process for the production thereof. Packaging containers of transparent synthetic material are suitable for receiving products such as for example socks and stockings, knitted underwear, compact discs, leather goods, books, hardware goods, tobacco, frozen goods, food products, pharmaceuticals or the like but they can also act as a packaging wrapper for more bulky articles such as for example pullovers, shirts or blouses or vests or footwear. It is known that the above-indicated articles are frequently packaged by using containers or wrappers of transparent synthetic material, being a thermoplastic material which is usually welded along the peripheral sides to join together the two superposed layers of film of synthetic material.
The wrappers or containers produced with superposed layers which are welded along the edges are often provided with printing on the outside thereof in order to afford the advertising slogans.
The operation of printing the advertising slogans is relatively complicated, the quality achieved is not outstanding and in practice the printing operation cannot be implemented in regard to a small numbers of packaging containers and wrappers.
In addition the advertising effect of the slogans which are printed directly on the synthetic material is not high quality.
A further disadvantage of the known containers or wrappers which are welded along the edges is that frequently the weld is not sufficiently strong for the use for which the container is intended.
In addition the containers which are known from the state of the art involve a reduced degree of three-dimensional stability. That fact requires that, during the packaging procedure, that is to say during introduction of the article into the wrapper, the article will have to be disposed within a reinforcing cardboard container. Such a packaging system is laborious and therefore expensive, leaving a generally unattractive part of the packaged product in view.
From the prior art are known packaging wrappers or containers printed with an offset of flexographic process, the result obtained is not of high quality and the known proceedings are useable only for volume production. The aim of the present invention is therefore to avoid the disadvantages which are encountered in the state of the art formed by the common holders or cases of paper and bags of welded material, and to propose a packaging wrapper or container and a process for the production thereof, which do not suffer from the disadvantages of the state of the art, which is resistant to the mechanical stresses involved and which has a layer of stiffening material acting as a reinforcement and at the same time as a carrier for advertising.
Another aim of the invention is to provide wrappers or containers of higher quality, making it possible to produce even small quantities in a rational and economic manner in a short time and with the optimum colour representation and efficiency.
That aim is achieved by a packaging wrapper or container which is composed of a first film of material which is partially covered by a reinforcing sheet containing advertising messages, and that joined to the first film of transparent material and the reinforcing sheet containing the advertising messages is a second film of transparent material which, on the side towards the reinforcing sheet having the advertising messages and towards the first film of transparent material, receives an adhesive layer.
The process as proposed in accordance with the present invention provides for the feed of a first film in roll form on which are disposed individual sheets acting as a reinforcement and an advertising carrier, that a second transparent film is then disposed on the first film and the reinforcing sheets, said second film being joined under pressure and by means of a layer of glue to the reinforcing sheets and to the peripheral edges which are not covered of the first film.
Thus the invention provides a wrapper in the form of a container, by means of two transparent layers. The two transparent films of synthetic material are glued together along the peripheral edges forming a very resistant wrapper or container and a reinforcing insert, for example a cardboard insert, having an advertising message on one or two faces, is precisely positioned and laminated and fixed in position in the interior of the wrapper or container.
Advantageously, a material involving the same chemical base (mono-product), for example a product based on cellulose or polypropylene, is used both for the sheet containing the advertising messages and for the films to be joined together.
The subject of the present invention will now be described in greater detail and illustrated by means of an embodiment given solely by way of example with reference to the accompanying drawings.
