SELF ADHESIVE LABEL- ENVELOPE (SEALED IN ROLL)
The product Self-adhesive Label - Envelope (sealed in a roll) is a self adhesive envelope in roll (1) that includes a sticker or a simple card (2) completely enclosed, that does not have any contact with the exterior environment of the self-adhesive envelope.
It functions as a self-adhesive label (envelope) that we can apply on a package with a labeling machine.
Then the consumer by pealing of the top layer of the lamination (drawing 3 numberl)from the specific- without adhesive- corner can reveal a sticker or a simple card for communicational or promotional purposes etc (drawing 3 number2) .
The raw materials that we use for the production of the self-adhesive envelope are:
a) For internal product sticker A double self adhesive material [liner (drawing 2, . a number 4) - intermediate self adhesive (drawing 2 . a number 3) -
Self adhesive material (drawing 2. a number 2)1.
b) For internal product simple card: Simple self adhesive [liner (drawing 2.b number 3) - self - adhesive material (drawing 2.b number 1)].
The self-adhesive material can be:
a. Any flexible material such as paper, plastic etc. b. Cold lamination with glue (removable without release varnish or permanent with release varnish) .

Description of production process.
Stages of production (drawing 4) . We import the double self adhesive material in the printing machine (drawing 4 number 1. We separate the liner (drawing 4 number 2) from the double self adhesive material. We print on the back side of the intermediate self- adhesive material. (Drawing 4 number 3) . We destroy the ' glue of the intermediate self-adhesive material, precisely behind the area that is defined from the artwork that will be printed on the front surface of the self-adhesive material. (Drawing 4 number 4) . Recombination of separated materials (drawing 4 number 5) . We print our artwork on the front surface of the self-adhesive material. The printing area will be perimetrically- approximately- from half up to one centimeter smaller than the final dimension of the envelope and precisely right above the area of printing and destruction of the glue (drawing 4 number 6) . We laminate with cold lamination in the lamination station the double self adhesive material . (drawing 4 number 7) . We destroy the adhesive on the back surface of the lamination on the corner from where the lamination will be peeled of at the final product, (drawing 4 number 8) . We separate the material that has resulted (lamination, self-adhesive material, intermediate self-adhesive material) from the liner (drawing 4 number 9) . In the first station of die cutting we engrave on reverse (back cutting) the intermediate self-adhesive material and the self- adhesive material, on the dimensions and the area where the glue is destroyed, by using the lamination as a base for the withholding of the sticker that we have created internally, (drawing 4 number 10) . We remove the waste of the engraving from the sticker or the plain card. (Drawing 4 number 11) . We recombine the separated materials. (Drawing 4 number 12). In the second die cutting station, we engrave in front the final dimension. We engrave what is called as sandwich of materials (lamination, self-adhesive material, intermediate self-adhesive material) using as a base the liner of the double self-adhesive material (drawing 4 number 13) . The area of engraving will be perimetrically from half up to one centimeter bigger than the interior cut (back side cut) . In the waste rewinder we collect the external part of the final cutting of the materials (drawing 4 number 14) . We collect the final product (envelope) in roll ready for the final slicing and quality control, (drawing 4 number 15) . The differences of "The product Self- adhesive Label - Envelope (sealed in a roll)" in comparison with other type of envelope-labels are: 1. Referring to the production process:
a) The seperation of materials for a second time before the first die cutting station (drawing 4 number 8 number 9 and number 10) .
b) The destruction of adhesive at the lamination material on the specified corner (drawing 4 number 8) c) The reverse die cutting (back and internally) of the intermediate self-adhesive material of the double self adhesive material, at the dimensions and the area where the glue is destroyed (for product simple card) , by using the lamination material as a base for the withholding of the sticker that we have created internally (drawing 5) . d) The removal of the waste from the sticker or the plain card (drawing 5) .
e) The recombination of the separated materials before the second die cutting station (drawing 4 number 12) .
This innovation in combination with the configuration of production as described in drawing 4 gives us as a result this pioneering final product.
2) Referring for the final product:
By using the above described pioneering technique, the sealed envelope that includes either a sticker either a simple card can be applied on a package with a labeling machine (drawing 1) . By using the appropriate materials, the self adhesive envelope can be also applied internally in a food package.
Drawing 1 portrays the Self-adhesive Label - Envelope (sealed in a roll) in a roll.
Drawing 2a portrays the Self-adhesive Label Envelope (sealed in a roll) with internal product sticker which is constituted by cold lamination with removable adhesive (drawing 2a number 1) , the self- adhesive material without release varnish (drawing 2a number 2) the intermediate sticker (drawing 2a number
3) and the liner (drawing 2a number 4) .
- Drawing 2b portrays the Self-adhesive Label
Envelope (sealed in a roll) with internal product simple card which is constituted by cold lamination with permanent adhesive (drawing 2b number 1) , the self-adhesive material with release varnish (drawing 2b number 2) and the liner (drawing 2a number 3) .
Drawing 3 portrays the Self-adhesive Label Envelope (sealed in a roll) placed on the product. By pealing of the top layer of the lamination from the specific- without adhesive- corner (drawing 3 numberl) then a sticker or a simple card is revealed (drawing 3 number2) .
- Drawing 4 portrays the stages of production for the Self-adhesive Label - Envelope (sealed in a roll) (sealed in a roll) that come in this order: Import a roll of double self adhesive material in the printing machine (drawing 4 numberl) , separation of the liner from the double self adhesive material (drawing 4 number 2) , printing on the back side of the intermediate self-adhesive material (drawing 4 number 3) , printing for the destruction of the adhesive of the intermediate self-adhesive material [precisely behind the area that is defined from the artwork]
(drawing 4 number 4), recombination of separated materials (drawing 4 number 5) , printing our artwork on the front surface of the self-adhesive material (drawing 4 number 6), cold lamination
(drawing 4 number7), destruction of adhesive on the specified corner (drawing 4 number 8), a second separation of the material that has resulted
(lamination- self-adhesive material - intermediate self-adhesive material) from liner (drawing 4 number 9) , reverse die cutting (back cutting of the intermediate self-adhesive material and the self- adhesive material) (drawing 4 number 9) , removal of the waste (drawing 4 number 10) , second recombination of the separated materials (drawing 4 number 11) , die cutting in front the lamination of the self adhesive material and the intermediate self adhesive material)
(drawing 4 number 12), collecting the waste of the final cutting (drawing 4 number 12) and collecting the final product (drawing 4 number 14) .
- Drawing 5 portrays analytically the intermediate stage of production of Self-adhesive Label - Envelope
(sealed in a roll) , where the printed and laminated double self-adhesive material, with the printed and destructed glue at the intermediate sticker [precisely behind the printed area of the self- adhesive material] (drawing 5 number 1) is separated from the liner (drawing 5 number 2) is die cut on the back (the intermediate self-adhesive material and the self- adhesive material at the area of back printing and glue destructed) (drawing 5 number 3) , the waste is removed from the sticker or the simple card
(drawing 5 number 4), the product (sticker or card) is created by using as a base the lamination (drawing 5 number 5) and finally the material is recombined with the liner (drawing 5) .
