Pinch Bottom Bags

The pinch bottom bag is in the style of an open mouth bag, either with or without a gusset. A stable bottom forms through filling of the bag and allows for an attractive product display at the point of sale. A variety of barrier materials are available to optimally preserve your product. The bag can either be supplied with a step finish with hot melt for heat sealed pinch top closure after filling or alternatively as flat top to be sewn by the customer.

Key Benefits
Excellent sealing properties When using heat seal closure, pinch bottom bags offer airtight sealing on both ends which protects the product from external agents and makes for a sift proof packaging. This closure method simply requires reactivation of the pre-applied hot melt.
Variety of barrier options This packaging solution is available with either a PE coated inner ply, a free film between the paper plies, or greaseproof paper, which can make up the inner and/or the outer ply of the bag.
PE coated paper or HDPE foil / free film (from 15µm to 100µm) or PP coated are available for water vapor transmission barrier.
Optimal palletisation Thanks to square bottom and the tapered form of the bag after filling the bags can be easily stacked and form a nice and stable pallet.
Attractive bag shape
The square bottom shape facilitates attractive product presentation. In combination with the bag tapering off to the top this bag solution appears most appealing.
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.
