Industry Standards For Felt Placemats

Industry standards typically measure the quality of felt placemats by parameters such as weight per square meter, thickness, and tensile strength. For example, household placemats usually weigh between 100g and 500g and are about 2-5mm thick, providing basic protection; while industrial placemats can weigh up to 20,000g and are over 20mm thick to withstand heavy loads or frequent use. Furthermore, environmental friendliness is also an important indicator; high-quality products must pass testing by organizations such as SGS to ensure no release of harmful substances such as formaldehyde and heavy metals.
