Our Products

Bancroft bag started providing solutions in 1924, branching out after World War II to offer Multiwall-paper bags to a variety of different industries. Bancroft Bag has always known that a “one size fits all” approach does not always translate into packing efficiency at your plant or the best solution for all products and markets.  This is why Bancroft Bag offers a wide range of packaging formats ranging from multiwall paper bags, to all plastic bags and pouches, and FIBC’s.

Our experienced sales, production, and technical team bring industry know-how by customizing the right bag for your operation.  We begin by thoroughly understanding your exact bag specifications and packing needs. 

Our ability to quickly provide you with both high and low-volume, quality bags accompanied with excellent technical and customer service sets Bancroft Bag apart from the competition.  Our responsiveness and in-house capabilities are second to none.

Self Opening Square

This style bag has gussets on each side of the bag with a square pasted bottom closure. The other end is left open for packing and can be closed by double folding, sewing, stapling or taping. This bag is suitable for a wide range of dry products such as corn meal, food ingredients, pet food, and non-food products such as charcoal, rock dust, and various pelletized products. These bags are suitable for a wide range of filling methods from manual to high speed automated filling lines.


The square end provides a good shape for palletizing and allows the bag to stand up unsupported for filling
