Effects of Process Parameters in Thermoforming of Unidirectional Fibre-Reinforced Thermoplastics
Process-induced defects during thermoforming are widespread problems in laminate manufacturing. The aim of this study is to describe the effects of holding time and pressure on several properties of the manufactured laminate. A design of experiments is performed, followed by an analysis of variance to examine significant effects. Subsequently, a regression model is created to predict the laminate’s properties, which is also validated. A significant interaction between holding time and pressure is determined for the resulting tensile strength and elongation at break with a p-value of 1.52 · 10−16 and 0.02, respectively…

Pioneering Sustainable Packaging in Southeast Asia
The inception and growth of Surya Indo Plastic (SIP), a thermoforming packaging manufacturer based in Indonesia, reflect a unique journey shaped by technical expertise, commitment to sustainability and a keen understanding of market dynamics, particularly in Indonesia and Southeast Asia. Being the region’s only company dedicated solely to producing 100% recycled PET (rPET) food packaging, by using post-consumer recycled materials rather than creating new plastic, SIP sets the example that packaging can and should be made sustainably. Their purpose is to make a difference through innovation, responsibility, and collaboration…
