Company News
This kind of bag has 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.
The sides that fold in repesent a gusseted. One of the main applications for gussets are their ability to add dimension to objects with height or width. Gusset bags hold significant quantities of material whether in granular, powder, or other forms. The gusset can be printed or without it.
When a bag is manufactured the gussets or the face of a bag can be woven using clear tapes which will display the product inside the WPP bag. This also means that the final user can view the product without having to open the bag to inspect the product.
