Referring to Fig. 1, a method for producing a plastic particle composition having a tea aroma according to an embodiment of the present invention comprises the steps of: performing a tea aroma extraction process to obtain a substance having a tea aroma (step S101); drying the substance (step S103); The dried substance is granulated with the first thermoplastic material to form a plastic granule composition (step S105).

In step S101, the tea residue which still has a large amount of tea aroma after the water extraction method is extracted by a tea aroma extraction process, for example, supercritical carbon dioxide fluid extraction, the operation pressure is between 100 and 400 atm, and the temperature is set. The extraction time is set to 60 to 360 minutes at 25 to 70 ° C to obtain a soluble substance, an insoluble matter or a combination thereof having a tea aroma. A soluble substance having a tea aroma can be further added to the tea beverage to increase the tea aroma. However, in this embodiment, the substance having the aroma of the tea leaves may contain a soluble substance having an aroma of the tea leaves, an insoluble matter, or a combination thereof.

In step S103, the tea aroma substance in the above step is dried at a temperature of -50 ° C to 50 ° C, preferably -40 to -20 ° C, to a moisture content of 0 to 20%, and A preferred moisture content is 8% or less. The substance having the tea aroma by this step has a lower water content, making it easier to form when it is granulated with the first thermoplastic material in a subsequent process. However, too high a drying temperature will cause the tea aroma in the substance having a tea aroma to be lost, so the drying temperature must be controlled at an appropriate temperature.

In step S105, the added content is 0.5-20% by weight relative to the total weight, preferably 1 to 10% by weight based on the total weight of the substance having a tea aroma and the content is 0.5-10 with respect to the total weight. The first thermoplastic material of the weight % is granulated at a temperature of 105 to 200 ° C, preferably 110 to 150 ° C, to form a plastic granule composition having a tea aroma. The first thermoplastic material may be selected from the group consisting of styrenes, olefins, polyesters, polyvinyl chlorides, and any combination thereof, which is selected according to the products to be manufactured in the subsequent process, and is preferably selected. It is an olefin. Among them, the styrene may be polystyrene (PS), the olefin (POF) may comprise polyethylene (PE), polypropylene (PP), and the polyester may be polyethylene terephthalate (PET), poly The vinyl chloride type may be polyvinyl chloride (PVC), but is not limited thereto.

In detail, a substance having a tea aroma and a first thermoplastic material are added to, for example, a high-mixer to obtain a premix, and then the premix is transferred to an extruder to be heated and kneaded to form a strand. Further, it is cut into a pellet composition such as pellets, but the shape is not limited thereto. Similarly, an excessively high granulation temperature in this step also causes loss of aroma components in the substance having a tea aroma, and therefore the granulation temperature must be controlled at an appropriate temperature. In addition, in step S105 In addition, additives such as pigments, dispersants, antibacterial agents, antioxidants and the like may be additionally added to increase the color or functionality of the plastic granule composition.

In the manufacturing method of this embodiment, since the source of the plastic particle composition is a soluble substance, an insoluble matter or a combination thereof with a tea aroma extracted by a tea aroma extraction process, the insoluble substance usually becomes a food processing. Waste, so by increasing the utilization rate of waste, it can not only reduce environmental pollution, but also save waste disposal costs. Further, in the process, drying and granulation are carried out using an appropriate temperature, so that the manufactured plastic granule composition can completely retain the aroma of the tea leaves.

Please refer to FIG. 2, which is a flow chart of manufacturing a packaging material using a plastic granule composition according to another embodiment of the present invention. In the present example, the process steps are similar to the previous embodiments, and the similarities are not described herein.

The composition and content are from 90 to 99.5% by weight, preferably from 95 to 99% by weight, based on the total weight, of the second thermoplastic material at a temperature of from 150 to 220 ° C, preferably from 160 to 180 ° C. At the temperature, the injection is performed to form a packaging material (step S107). The packaging material has a content of from 0.2 to 5% by weight, based on the total weight, preferably from 0.5 to 1.5% by weight, based on the total weight, of a tea aroma. The second thermoplastic material may be selected from the group consisting of styrenes, olefins, polyesters, polyvinyl chlorides, and any combination thereof, which are selected according to the packaging material to be produced, preferably olefins. . Among them, styrene can be polystyrene The olefin (PS), the olefin (POF) comprises polyethylene (PE), polypropylene (PP), the polyester may be polyethylene terephthalate (PET), and the polyvinyl chloride may be polyvinyl chloride (polyvinyl chloride). PVC), but not limited to this.

Specifically, the plastic granule composition having the tea aroma and the second thermoplastic material are subjected to a molding machine, for example, a compression molding machine, at a cylinder temperature of normal temperature, a mold temperature of 20 ° C, and a molding pressure of 50 bar to 150 bar. Press to obtain the packaging material.

In one example, 1% by weight of the tea aroma relative to the total weight and 99% by weight of the first thermoplastic material relative to the total weight, which is added to the high mixer after mixing, obtains a premix. Then, the premix was transferred to an extruder and heated at 130 degrees, kneaded to form a strand, and then cut to obtain a plastic pellet composition. Next, 10% by weight of the total weight of the plastic granule composition having tea aroma and 90% by weight of the second thermoplastic material relative to the total weight, which is a polyethylene using a molding machine, at a cylinder temperature of normal temperature ° C, The injection is carried out under the conditions of a mold temperature of 20 ° C and a molding pressure of 50 bar to 150 bar to obtain a packaging material, for example, a bottle cap, but is not limited thereto.
