When sourcing paper table cloths, the basis weight (GSM - Grams per Square Meter) is the primary indicator of quality. For standard events, 50-70 GSM is sufficient, while premium settings require 80-120 GSM or multi-ply (2-ply or 3-ply) tissue bonded with a poly-film. Ensure the product features liquid resistance or waterproof PE film backing to prevent spills from damaging the underlying furniture. For high-end hospitality, look for 'Airlaid' paper, which mimics the feel of linen while remaining disposable.
