Exploring the impact of coating grammage reduction and temperature-speed relation in paper cup production

Abstract

The purpose of the study is to examine how coating grammage reduction affects the overall quality, leak resistance, and structural integrity of paper cups. It also explores the effect of temperature-speed variations on achieving proper side seam and bottom sealing throughout the paper cup manufacturing process and estimating the required temperature settings at high production speeds. To accomplish this objective, two main manufacturing trial runs for two Reference and Experimental materials has been employed followed by the range of qualitative and quantitative methodologies. This study's methodology includes the Fibre Tear Evaluation, which analyses sealing integrity, liquid tests to examine the tightness and integrity of paper cups, and dimensional measurements and data analysing tools. The results of this thesis show that, irrespective of the type of material, leaks appear at the bottom of paper cups. This emphasises how vital it is to regulate bottom temperature to lessen sealing issues. In addition, the temperature sensitivity of the Experimental material was larger than that of the Reference material. Considerable variations in temperature between the side seam and bottom of the Experimental material indicate possible difficulties in preserving structural integrity and consistent sealability. Considerable variations in temperature between the side seam and bottom of the Experimental material indicate possible difficulties in preserving structural integrity and consistent sealability. This study also includes a method for determining temperature settings at high speed rates, which makes the temperature monitoring and adjustments easier.
