All you hear sound like waterproof, water boring and water resistant but you may not know about their differences and uses. All types are meant for water protection and are very essential for bags and baggage.
Bags are available with three types of water protection.
Water Resistant Bag: They are made with special processed material and are woven tightly to prevent water. But the zippers here are formed with the standards of waterproof jopar, but after the supply of water at the specified level, the bag can be entered. Use these standard zippers, traditional stitching techniques with holes in their teeth. It does not actually cover the holes placed in the jeep, which allow the water to enter. Such bags will eat completely during heavy rain or water drowning.
Waterproof Bag: They are well prepared with high cloth and are coated with good finish to prevent water from inside. When the water hits, the fabric becomes composed of small beads on the surface. In this way, water resistant bags provide better water protection than water resistant bags. However, instead of keeping the water lip instead of waterproof zipper, the standard jeeps are still used in the bag.
Waterproof bags: The thermoplastic polythene (TPU) or PVC plastic that is used to wear waterproof bag fabric. Thereby providing complete protection from water. These bags are prepared with seams that are ultrasonically welded before installing waterproof zippers. No holes and needles are found in the waterproof japars, thus they can not leak through the water. Moreover, more than two roll-top closures are used after the opening of the bag. This bag leads to fully airtight and waterproof.
The main differences found in all the above water-protected bags are:
• Used in a special fabric water resistant bag, which is tightly woven without specific coating, when various types of plastic coatings are used in water to prevent biting and waterproof bags from sharp water.
Waterproof bags are welded ultrasound to prevent water, when the water gates of water resistant and water boring bags are allowed.
• Waterproof bag also roll top closure system, which is an add-on protection of water. However, these extra features are not a part of the water boring and water-resistant bag.
Therefore, it can be observed that waterproof bags use waterproof razors instead of standard zipper used in water resistant and waterproof bags.
SBS bags provide waterproof jap with different materials to make it more annoying. There is a thin layer of TPU film on the coil zipper for rubberizing plastic tape and water retrieval. Glittery, matte and semi-matte surfaces are available according to the requirements of zippers customers. In addition to this type, there is a water-painted or air-tight yippers, known as sealed airtight waterproof metal h ipper. They are made of two fabric tape and both ends are sealed with chloroprene rubber and fixed outer by an internal tooth fabric tape. This pressure and bending are open while providing protection against water, air, dust, sunlight.
