What kind of VOCS Leakage cover

1. Slider zipper is a type of zipper that has a slider or a puller that moves along the teeth of the zipper to open and close it. It is also known as a regular zipper or a conventional zipper. A slider zipper consists of two fabric tapes with teeth that interlock when the zipper is closed, and a slider that moves up and down the teeth to adjust the opening. The puller can be made of metal, plastic, or nylon materials, and can come in different shapes and designs for easy use and decoration purposes.

2. Double flange zipper is a type of zipper that has fabric flanges or tapes on both sides of the zipper chain. The two flanges provide a wider surface area for easy sewing and attachment to the fabric, and they also help to prevent the zipper from getting caught in the fabric when opened or closed. Double flange zippers are commonly used in heavy-duty applications such as industrial covers, where a stronger and more durable zipper is required. They are available in different sizes, materials, and colors, and can be customized to meet the needs of the product.
