  PP/HDPE WOVEN VALVE BAGS with / without Perforation
Technical Name: Polypropylene / bags valve bags for automated filling plants

We offer custom manufactured, Valve Bags. It owns an opening or Valve in one corner through which the bag is filled. The valve is made with an inner flap which functions as a self-closing check valve after filling. It is available with a plain valve or with an extended inner sleeve. If an extended "tuck-in sleeve" is used, the sleeve is manually folded down and back into the pocket under the sleeve for positive closure against sifting. These bags have tiny air holes so called as perforation that allow the product to breath, enhancing the shelf life of the products.

The valve bag includes a bag body having a valve end portion, the valve end portion constructed to form a filling passage in which a valve sleeve is inserted. The valve sleeve has a first end extending into the interior of the valve bag and a second end extending exteriorly from the bag body. A valve protection member is secured to the second end.
