Jute bags are not naturally waterproof due to the absorbent nature of jute fibres. They may become damp when exposed to moisture. If you require waterproof bags, you might consider alternatives like:

Waterproof coated bags:
Some jute bags have a waterproof coating or lining added to make them water-resistant.

Less water consumption:
It is a water-efficient crop, requiring less water to grow than cotton or linen. This makes jute a more sustainable option from an environmental standpoint.

Synthetic fibre bags:
Bags made from materials like polyester or nylon offer water resistance and can be suitable for wet conditions.

Specialty waterproof bags:
Look for bags explicitly designed for waterproof purposes, such as dry bags used for outdoor activities.

While jute bags have their unique eco-friendly qualities, these alternatives can help fulfil your need for waterproof bags in specific situations
