Description

Intelligent paper straw manufacturing facility and paper straw manufacturing method using the same}

The present invention relates to an intelligent paper straw manufacturing facility and a method of manufacturing paper straws using the same. More specifically, the present invention relates to an intelligent paper straw manufacturing facility and a method of manufacturing paper straws using the same. In more detail, it has oil resistance and water resistance, does not require special separation when discharging, and does not cause environmental pollution by biodegrading after disposal. The present invention relates to an intelligent paper straw manufacturing facility capable of manufacturing straws of a predetermined shape by significantly improving the automation and convenience of the manufacturing process compared to coated paper and existing paper straw manufacturing methods using existing base paper, and a paper straw manufacturing method using the same.

Plastic is usually cheap and durable, so it is often used as a material for straws that suck up food and beverages.

Plastic is known to be a recyclable raw material. However, in general, during the manufacturing process of plastic products, they are made difficult to recycle from the manufacturing stage, or are often discarded as is due to contamination or damage during the discharge or collection stage. The recent video of a plastic straw being pulled out of a sea turtle's nose and the plastic waste pile Plastic Island clearly show this reality.

Accordingly, there has recently been a movement to ban the use of plastic straws.

Paper straws are sufficient as a substitute for plastic straws.

Paper straws have been used in the past, but due to manufacturing cost issues, their sales are known to be only 0.1% of plastic straws.

In addition, existing paper straws inevitably require adhesive due to their structure, which causes the problem of adhesive separation (migration) during the user's drinking process. Adhesives such as PLA (Polylactic Acid) or PVAc (Polyvinyl acetate) are dissolved in high-temperature drinking water and enter the user's mouth. This ultimately leads to increased manufacturing costs, including the need to use adhesives that are harmless to the human body.

In addition, coated paper made with a water-soluble adhesive using starch such as tapioca absorbs moisture quickly due to the nature of starch, and there is a risk that the straw will easily unravel or bacterial growth due to difficulties in managing humidity in the summer, leading to other distribution and storage problems.

Accordingly, in recent years, there has been a need to provide paper straws that are harmless to the user's human body and to develop eco-friendly paper straws that can be naturally decomposed after use.
