What impact do coatings of different thicknesses have on the performance of woven bags?

Different thicknesses of coatings have a significant impact on the performance of woven bags, which is reflected in waterproof performance, strength and durability, chemical resistance, UV resistance, printing quality, flexibility and operability, cost and environmental impact, etc. aspect. A thicker coating provides better waterproofing performance because it forms a stronger barrier that effectively blocks moisture penetration while increasing the overall strength and durability of the woven bag, allowing it to withstand greater weight and frequent use. Used to reduce the likelihood of tearing and wear. In addition, the thicker coating can better protect the contents of the bag and resist the erosion of chemical substances when encountering corrosive substances such as acids and alkalis.

In terms of ultraviolet protection, thicker coatings can more effectively resist ultraviolet erosion, extend the life of woven bags when used outdoors, and prevent materials from aging and embrittlement due to ultraviolet radiation. In terms of printing quality, thick lamination provides a flatter surface, which facilitates high-quality printing, and the printed pattern is not easy to fall off due to friction or moisture. However, although the strength and durability are enhanced, an excessively thick coating may make the woven bag harder, affecting its flexibility and ease of operation, such as inconvenience during filling or sealing.

Relatively speaking, although the thinner coating is slightly weaker in terms of waterproofing, durability and chemical resistance, it maintains the flexibility and maneuverability of the woven bag, making it easier to operate and handle, while also reducing cost. More economical, with less impact on the environment during production and processing. However, woven bags with thinner coatings sacrifice strength and durability, and may age and damage faster, especially when exposed to UV rays or high humidity for a long time.
