- the second film layer was coated with amorphous polylactic acid (a product of SKC Co., Ltd.) having a thickness of about 1 ⁇ m as the third film layer without coating the first film layer on the second film layer.
- a biodegradable film was prepared.
- a three-layered biodegradable film was prepared in the same manner as in Example 1, except that the third film layer was coated with an OP coating-based compound (Yulchon's ECOBY-OPP product) having a thickness of about 1 ⁇ m.
- an OP coating-based compound Yulchon's ECOBY-OPP product
- Example 1 and Comparative Examples 1 and 2 have physical properties suitable for packaging of cigarettes, thermal shrinkage, oxygen permeability, moisture permeability, airtightness and haze were measured and shown in Table 1 below.
- the method for measuring each physical property basically followed a general method in the relevant technical field, and was specifically measured according to the method specified in the above description.
- the heat shrinkage rate is a value obtained by subtracting the lower value from the higher value among the heat shrinkage rates in the longitudinal direction and the width direction.
- Example 1 physical properties suitable as in Example 1 for packaging tobacco products by introducing the first film layer and the third film layer as appropriate materials even after filling the second film layer with a biodegradable film of about 90% by volume or more It can be confirmed that a biodegradable film having a can be prepared.
- a biodegradable film having such physical properties may be difficult to achieve without any one of the first film layer and the third film layer as in Comparative Example 1, and as in Comparative Example 2, a well-known coating material in the coating field Even coating can be difficult to achieve.
