Description

{Adhesion adjustable labeling device of pet bottles and labels}

The present invention relates to a labeling device that can control the adhesion of the PET bottle and the label, and more particularly, to a labeling device capable of adjusting the adhesion of the PET bottle and the label to facilitate the removal of the label attached to the PET bottle for recycling the PET bottle.

In general, a label is attached to the outside of the PET bottle containing the name, source, and information about the contents contained therein.

In the past, this information was printed directly on the surface of the container, or a label sticker was attached to the outside of the container, such as a sticker labeling device, to provide consumers and buyers with information about the product. It is difficult to print on plastic bottles or glass bottles of plastic materials, and when the container is to be recycled, it is very difficult to remove the sticker from the container.

Accordingly, in the "labeling apparatus using a heterogeneous adhesive and a PET bottle manufactured by the apparatus" of Korean Patent Application Publication No. 10-1926127, which is filed and filed recently by the present applicant, adsorption is performed between the feeding drum and the rotary table along the feeding direction of the label. It proposes a technique for labeling device comprising an adhesive applying means is installed in close proximity to the outer peripheral surface of the drum, the adhesive applying means comprises a first spreader for applying a water-soluble adhesive and a second spreader for applying a hot melt adhesive It was.

As a result, the water-soluble adhesive applied between the label and the PET bottle was dissolved in water when recycling, so the label and the PET bottle were classified due to the specific gravity difference, so that only pure PET can be collected, but it is cumbersome to have two different adhesives. Due to the structure in which the water-soluble adhesive is applied only to the center portion of the film, it was found that the label was easily removed from the PET bottle during the distribution and sale of the beverage product.

In addition, the PET bottle is recycled in small pieces to be made into flakes. In this case, when the adhesive area of the label paper is wide, the labels are stuck on the cut flakes.
