PET material is more robust, durable, and heat-resistant compared to PP.
However, PP is softer, lighter, and easier to process and mold than PET.

GSM (grams per square meter); oz/yd² (Ounces per Square Yard).
In the nonwoven fabric industry, GSM is a key indicator that represents the weight of nonwoven fabric per square meter. It directly reflects the thickness and density of the material and is an important parameter for measuring the quality, strength, and use of nonwoven fabric. To convert from oz/yd² to GSM, use the formula: GSM = oz/yd² * 33.906, which means 1 oz/yd² is roughly equal to 33.906 GSM.
