  • 1. PE-PP Blending condition for plastic bag properties
    본 실험의 목적은 다양한 PE 혼합비(0:100, 50:50, 10:90)를 적용하여 Blending한 후, 해당 시료의 TGA 및 DSC 분석을 통해 열적 특성을 평가하는 데 있다. 이를 통해 PE와 PP의 혼합비율에 따라 분해온도(Td)와 융점(Tm)의 변화 양상을 확인하고, PE와 PP의 상용성을 높이기 위한 조건 설정에 참고 자료를 제공하는 데에 있다. 추가로, Hot press를 이용한 필름 제작을 통해 PE와 PP의 물리적 특성 변화를 관찰할 계획이다.

  • 1. PE-PP Blending condition for plastic bag properties
    The blending of polyethylene (PE) and polypropylene (PP) is a common practice in the production of plastic bags to achieve desired properties. The specific blending conditions, such as the ratio of PE to PP, the processing temperature, and the mixing time, can significantly impact the final properties of the plastic bag. To optimize the PE-PP blending for plastic bag properties, several factors need to be considered. The ratio of PE to PP is crucial, as it determines the balance between the flexibility and stiffness of the material. Generally, a higher proportion of PE results in a more flexible and stretchable bag, while a higher proportion of PP leads to a stiffer and more rigid bag. The processing temperature also plays a role, as it affects the viscosity and flow behavior of the polymer blend, which in turn impacts the bag's strength, tear resistance, and overall performance. Additionally, the mixing time and intensity can influence the homogeneity of the blend, affecting the consistency and uniformity of the bag's properties. To achieve the desired plastic bag properties, the PE-PP blending conditions need to be carefully optimized through a combination of experimentation, material characterization, and performance testing. This may involve adjusting the blend ratio, processing temperature, and mixing parameters to find the optimal balance between flexibility, strength, and other key properties required for the specific application. Continuous monitoring and quality control during the production process are also essential to ensure consistent and reliable plastic bag performance.
