- the film curled in the direction of the maximum shrinkage of the film, which causes the pressure or flow rate of the water to increase when the label floats to the top of the bottle, but in the case of Examples 29 and 30, the label is separated from the bottle. Since shrinkage occurs in both directions at the time to mitigate labeling, the label can be easily floated to the top of the bottle when compared to other embodiments to separate the label, which is advantageous in terms of water consumption and energy saving.
- Comparative Example 4 which does not use a heat-shrinkable polyester-based film, it can be seen that the peeling of the label in the simple hot water is substantially impossible.
- Example 15 without applying the protective layer, the adhesiveness and peeling characteristics are not a problem, but during the printing label peeling process, the phenomenon that the metal deposition layer and the printing layer of the printing label peel off occurs, This may cause a problem of contaminating the present invention, which may cause secondary contamination of the bottle, resulting in a problem of additional cleaning of the bottle.

It can be confirmed that economic efficiency may be reduced. This is caused by a high shrinkage start temperature and a low maximum shrinkage stress, it can be seen that the shrinkage characteristics are preferably controlled to optimize the peelability of the label.

- a deposition film having the same structure as in Example 33 10% by weight of acrylic resin (BPS-5698, Samyoung Toyo) on the metal deposition layer, 80% by weight of methyl ethyl ketone (MEK, chemical instead of ketone) Yellow pigment (Yellow 10G, Hyundai Chemical), Red pigment (Red-FRN, Hyundai Chemical), Green pigment (Green 735, Hyundai Chemical), Black pigment (Black # 30, Hyundai Chemical) and White pigment (R-100, KPIA) was printed with two degrees using a gravure roll from two crude liquids containing 10 wt% of each colorant selected in the present invention and the total amount was adjusted to 100 wt% to form a printed layer (print layer thickness 0.2 ⁇ ).
- the obtained deposition film was evaluated by the above-described method, and the results are shown in Tables 5 and 6 below.
- a deposition film having the same structure as in Example 33 was prepared, except that PET film 50 ⁇ m (H34, Kolon Industries Co., Ltd.) was applied as a base film, and the metal deposition layer thickness was 52 nm and the print layer thickness was 2.0 ⁇ m. , A protective film thickness 0.4 ⁇ m, a bending film having a thickness of 1.0 ⁇ m anti-warp layer was prepared.
- the obtained deposition film was evaluated by the above-described method, and the results are shown in Tables 5 and 6 below.
- Example 33 Prepare a deposited film having the same structure as in Example 33, except for not forming a warpage prevention layer to prepare a deposited film having a metal deposition layer thickness 52nm, printed layer thickness 2.0 ⁇ m, protective layer thickness 0.4 ⁇ m It was.
- the obtained deposition film was evaluated by the above-described method, and the results are shown in Tables 5 and 6 below.
- the label in the type of floating type bleaching machine where water is introduced into the bottle and the label is raised to the surface using water pressure, and the label separated using a hook from the top of the bottle is stretched only in the width direction of the film.
- the film curled in the direction of the maximum shrinkage of the film, which causes the pressure or flow rate to increase when the label floats on the top of the bottle, but in the case of Examples 45 and 46, the label is separated from the bottle. Since shrinkage occurs in both directions at the time to mitigate labeling, the label can be easily floated to the top of the bottle when compared to other embodiments to separate the label, which is advantageous in terms of water consumption and energy saving.
- the thickness of the metal deposition layer is thin, as in Example 48, the total light transmittance of the heat shrinkable deposition film is high, so that the color of the bottle is projected when applied to colored bottles in the printing label, which is the final product, and the printing effect is reduced. As a result, it may be confirmed that the aesthetics of the advertisement may be reduced. Therefore, when considering the visibility it can be seen that the thickness control of the metal deposition layer is required.
- the shrinkage start temperature is high and the maximum shrinkage stress is low, as in Example 49, the printing label is sometimes adhered to the bottle when the printing label is removed from the bottle, and thus the printing label is removed several times. Since economic efficiency may be reduced, it may be confirmed that the shrinkage start temperature, the maximum shrinkage stress, and the like are more preferably controlled.
- Example 47 without the protective layer, the adhesiveness and peeling properties are not a problem, but the printing film peeled off due to the phenomenon that the metal deposition layer and the printing layer of the printing label peel off during the printing label peeling process. This may cause a problem of contaminating the present invention, which may cause secondary contamination of the bottle, resulting in a problem of additional cleaning of the bottle.
- the overall fairness is not a problem, but since the cleaning process of the bottle must be added after peeling off the printing label, it may cause an increase in process cost when the printing label is applied.
