Abstract
현재 포장 공정에서 사용되고 있는 stretch wrapping 공정은 초기 포장기의 장치 구비 등의 가격문제와 사용 후 폐기되는 포장재의 처리문제가 심각하다. 이에 대해 미끄럼 방지 접착제(Slip-resistant adhesive)를 사용하여 물류를 고정하여 운반하는 방식은 간단한 접착제의 도입으로 폐기물 발생이 없고 공정이 간단하며 비용이 매우 낮은 장점을 지닌다. 본 연구에서는 다습한 환경에서 polyethylene 필름 상에 미끄럼 방지 접착제를 적용했을 경우 접착력이 저하되는 것을 peel test를 통해 확인하고 적절한 첨가제의 선정 및 도입을 통해 접착력을 개선하는 연구를 수행하였다. 이를 통해서 maltodextrin의 첨가 시에 내습성에 대한 개선으로 인해 미끄럼 방지 접착력의 저하가 억제되었으며 10 wt% 도입 시에 최적의 성능을 나타내었다.
Stretch wrapping processes that are used to the packaging process had a serious problem of high price and treatment of used wraps. On the other hand, slip-resistant adhesive provides the advantage of simple process, low cost, and free from after-use treatment. In this research, adhesion deterioration of aqueous slip-resistant adhesive adhered to polyethylene film under the moisture condition using aqueous slip-resistant adhesive was observed by the Peel Test._x000D_
Improvement of adhesive property under the moisturizing condition could be obtained by the selection of appropriate additives. As a result, introduction of maltodextrin reduced the deterioration of slip-resistant adhesion owing to the improved moisture resistance and introduction amount of 10 wt% of maltodextrin showed optimal performance.
