Sewn Open Mouth Bags

Open mouth bags are closed on one side of the tube, either by sewing or by gluing. The high quality materials and types of construction offered provide a longer shelf life for your products. Re-opening devices can be applied, so that the product remains protected for a longer period by the end user. A choice of bleached or unbleached paper is available, with basis weights ranging from 40# to 70#. Design facilities and printing with up to 8 colors can be provided, including process printing. Coatings can also be optionally applied to give a gloss finish or improve frictional characteristics. For special protection via a barrier, open mouth bags are available with a film liner, such as PE-Inliner.

Key Benefits
Yields a neat, stable pallet Open mouth bags can be designed with different bottoms, resulting in a sturdier bag with a nicer shape – for an optimal pallet.
Self-supporting for display Special folding techniques and gussets help form a nicely shaped bottom during the filling process, thereby providing a pleasing, self-supporting display at the point of sale.
Various closure techniques. The available bag closure techniques meet a variety of customer requirements, including sewing or folding over/ gluing down, or the bags can be equipped with a re-opening device.
Meets various filling prerequisites Open mouth bags can be used with a wide range of filling equipment for fully automated or manual filling.

Optional Features
Easy Open An integrated tear-open strip allows easy opening of the bag to quickly release the content. This feature avoids paper shreds, which may contaminate the filling good when opening the bag with common devices  and at the same time eliminates risks of injury.
Security Label The highly sophisticated anti-counterfeiting label successfully combats product forgery.
