Factory Introduction

Taizhou K.K was founded in 2003 solely by Taiwan K.K. and has been striving for providing the cutting-edge plastic bottles and jars, including MS, SAN, ABS, PP, PET, PETG, PE etc. Over the years, it has invested more than 100 injection/blowing machines, comprehensive decoration equipment and assembly lines.



Taizhou K.K was founded in 2001 solely by Taiwan K.K. at Jiangsu Province, Taizhou developing zone. It’s about 3.5 hours from our factory to Shanghai port which makes it convenient exporting our skincare and cosmetics packaging from Shanghai, China to other countries. Since we have acquired another industrial area of 79500 square-meters in Taizhou for building the new production facility, we plan to move to the new factory in the end of 2018. At that time, our factory scale will be 4 times bigger than now.



Our current plant area is 20,000 square meters in Taizhou developing zone, but soon we will move to a new plant of 80,000 square meters in the end of 2018. With four times bigger area, our annual capacity can lift to 10-15 million pcs per year. There are several departments in our factory which include molding department, forming department, coloring department, printing department, assembling department, Quality Assurance department and warehouse department.

In the molding department, we have both public molds and private molds for certain customers. Currently we have over than 500 sets of public molds and we have professional operator to check the molds regularly in order to maintain the best production condition. In the forming department, we have both injection machine, inject-blow machine & blowing machine which produce different parts of packaging like cap, inner bottle, outer bottle, protective disk, etc.

In the coloring department, we have both paint division and spray painting room. In the paint division, we can adjust any color you want according to the pantone color number. While in the spray painting room, we have both automatic spray painting section and also manual spray painting section which is responsible for different packaging part, and different decoration type. We have set a water wall facility in our spray painting room in order to protect our employee’s healthy. The polluted elements in the air can be taken away by the water fall.

In the printing department, we have both hot stamping machine and silk screen printing machine. After the production, all the parts will be sent to our assembling line for doing 100% on-line quality inspection. All our employee is required to wear hats and uniform in case of any dust or hair falling into our packaging. After assembling, finished products will be moved to warehouse and wait for shipping.
