An open mouth bagging machine fills pre-made bags through their open top with an accurately weighed amount of product, typically powders, granules, seeds, pellets or feed. The bag is then closed by sewing or heat sealing. Proquip Solutions is the authorised New Zealand distributor for AT Sack open mouth bagging machines. See the AT Sack open mouth range.

Open mouth filling fills bags through an open top, which is closed after filling, and suits a wide range of free-flowing products. Valve sack filling fills bags through a small valve in one corner, which closes itself after filling. Because the bag stays almost sealed, valve filling is preferred for dusty or fine powders such as flour, cement and chemical powders. AT Sack makes both types. See the AT Sack valve sack range.

AT Sack bagging machines fill free-flowing products including flour, sugar, food powders, seeds, grains, animal feed, pet food, fertiliser, chemical powders, plastic pellets, aggregates and recycled materials. They are used by food manufacturers, pet food producers, horticulture businesses, chemical processors and industrial manufacturers across New Zealand.

AT Sack machines fill a wide range of bag weights, from smaller bags up to 50kg sacks depending on the model. The Simplafill S1000GR weighs and fills granular and powder products accurately across multiple weight ranges. Our team can match the model to your bag size, product and output.

Open mouth sacks are usually closed with a bag sewing machine, which stitches the top of paper or woven bags, or with a heat sealer for plastic bags. Valve sacks close themselves after filling. The right closing method depends on your bag material and product, and can be matched to your AT Sack filler.

Semi-automatic bagging machines have an operator place each bag while the machine weighs and fills it, which suits lower outputs and businesses moving up from hand filling. Automatic systems place, fill and move bags with less labour, and suit higher outputs. AT Sack offers both, so the choice comes down to how many bags per hour you need and your available labour.
