Introduction to waterproof bags

Waterproof bags are essential items for water activities, outdoor travel, and diving. The bag is made of waterproof material, and the seams are waterproofed.

During water sports and outdoor activities, you can put your belongings into waterproof bags to ensure that they are dry.

There are two types of waterproof bags, one is a general waterproof bag and the other is a professional waterproof bag.

General waterproofing: General waterproofing refers to the waterproof fabric sewn with needlework technology, and then attached with waterproof tape to prevent water from entering the needleholes.

Professional waterproofing: Professional waterproofing can be divided into two types:

1. The waterproof level is the highest requirement in terms of technology and materials. This kind of waterproof bag is mostly used for outdoor rafting. The material is mainly 500D-1000D clip mesh or TPU composite. The process uses high-frequency voltage to heat-melt the two pieces. The materials are seamlessly fused, and then reinforced with about 15CM of transparent material that is transparent and smooth at the bag mouth. The outer part is folded in three parts and the inner part is folded in three parts. This processing method makes it truly waterproof (it can be used as a lifebuoy after inflating).

2. Submersible grade waterproof: There is a waterproof bag for phones or cameras on the market that can be waterproof to a depth of 10 meters. The waterproof degree of the waterproof clip can reach a depth of 10 meters to 20 meters underwater.
