Polymer Sealing and Bonding Resistance to the Tensile Strength of Flexible Food Packaging

Polymer is a very important material when used as packaging, such as flexible food packaging which is engaged in the industrial world. The packaging process is carried out using a rotogravure printing machine with the procedure stage. To test the feasibility of the polymer material used, several samples will be taken to be tested at the Quality Control Laboratory, one of the parameters is Sealing and Bonding. Sealing and Bonding are types of tensile testing with the aim of measuring the tensile strength of seals or bonds of an object, while the function of testing in companies engaged in the packaging sector is to find out whether the polymer material being processed is in accordance with packaging company standards or in accordance with consumer demand. In this study, the seal strength temperature used was in accordance with packaging standards (150°C) with a speed of 280 mm/min, while for bonding strength using a speed of 250 mm/min with a withdrawal distance of 50 mm (5 cm), the thickness of the specimen tested approximately 70μmm
