AWE Pinch Bag Closer For Open Mouth Bags
AWE’s Pinch Bag Closer PBC Series can reduce or eliminate the need to manually perform repetitive tasks of sealing the plastic inner liner with a hermetic heat seal and closing the paper open mouth bags. The Pinch Bag Closer seals multi-wall paper bags with a fast and reliable process. The Pinch Bag Closer is capable of handling Stepped End Bags, which have a pre-applied, hot melt adhesive strip positioned along the top flap of the bag. The Pinch Bag Closer folds the flap and then heat & pressure are applied, to seal and close bag. Your bag is now sift-proof.
Sealing Your Sack Could Not Be Any Easier
Your PBC series Pinch Bag Closer uses HEAT and PRESSURE to seal and close your bags. The Pinch Bag Closer is designed to perform 2 primary functions: Seals the inner plastic liner within a multi-wall bag.
Close reactivates (melt) reapplied hot melt adhesive on the stepped top edge of the bag and then folds this over to form a closure.
The heat, pressure and time are electronically controlled from the HMI Screen.
The bag slides along on either gravity rollers or conveyors and the top of the bag is positioned manually in the infeed guides and continues along the conveyor until bag is positioned centrally. Once the foot switch or push button is engaged the PBC controls take over, the bag faces are flattened together by the mating faces to ensure even pressure and correct alignment.
To fuse an inner poly liner of a multi-wall paper bag requires heat from the seal bar which has 2 elements in the aluminum heated die. This process is controlled by a temperature control module within the PLC.
Once the top edge of the bag hits the bag stop plate, the fold line is formed against the stainless steel folding blade which is incorporated into the sealing bar. The folding plate rotates to 80° folding the top 40-50mm (1½” – 2”) of the bag with a parallel fold.
Finally the folding plate rotates back, applying pressure to the molten adhesive and then it to cools, bonding with the paper, creating siftproof bag. The Hot melt adhesive bonds to the paper and fill gaps to produce high-integrity barrier seals, eliminating the need for costly over-wraps or bags.
This results in a hermetically sealed bag and is commonly used in toxic products or products that are hydroscopic. Widely used to package fine powder products, premium pet foods, premix food products, animal feeds, chemical and hazardous products.
The closed sealed bag is then transferred to a non-stick compression belt section, providing a well fused seal.
For Sealing Your Open Mouth Bags
For best results, make sure the bag is central in the PBC to ensure the sealing bar has contact with the entire face of the bag.
A good closure should have ‘fibre tear”. That is, the paper should tear, rather than the adhesive releasing when the closure is opened.
The Pinch Bag Closer is designed to operate with one of the smallest head spaces of any sealer available, but it still needs some head space above the product for efficient operation.
Note: Insufficient head space (ullage) to the unfilled space in a container of liquid above the product will make sealing and closing difficult, if not impossible. The correct bag size is therefore required to suit the product density/dustiness.
