Bags and sacks have a long tradition: even in the early days of civilization, leather, linen and cotton bags simplified the transport and storage of goods. Until the turn of the century, they were the most common packaging material for bulk goods such as grain, flour and salt. 

In the Middle Ages, paper bags and pouches were used, especially for smaller filling products. These were particularly suitable as practical and inexpensive packaging materials for disposable packaging. Since the beginning of the 19th century paper bags have been produced industrially by hand and since the middle of the 19th century also by machine. 

At the beginning of the 1960s, paper as a packaging material was supplemented by more economical plastic foil suitable for the packaging industry. Food and feed products in particular, which are free-flowing, powdery, chunky or granular, are today packed in plastic foil bags.

When it comes to bag packaging, the block bottom bag is a must-have: the special shape of the bottom gives the bag stability and load-bearing capacity and enables it to stand securely. This not only simplifies the storage of several bags, but also ensures easy removal of the packaged product. 

The different versions of the head also make the block bottom bag a real all-rounder that can be used in all markets. 

The decision for a certain variant of the block bottom bag is not only based on the properties and demands of the product, but also on the quickest possible identification of the product at the point of sale and also serves to visually differentiate it from competing products.

Variants of the Block Bottom Bag

Block Bottom Bags with a Gable

Gable bags are used in all markets. Whether in the fields of food, pet food or non-food: the gable provides a consumer-friendly and easy pouring of the bulk material.

Block Bottom Bags with Edge Sealing

Due to the sealing on all four sides, edge sealed bags achieve an even higher strength and stability. They also stand securely without support and are therefore particularly suitable for product presentation at the point of sale.

Block Bottom Bags with a Clip Closure

Resealable bags are particularly handy. The clip enables the consumer to reseal the bag after a partial removal of the product.

Air Free Block Bottom Bags

Low-air bags compress the product when packed into the bag, which not only saves the foil used, but also takes up less space during transport, storage and at the point of sale.

Block Bottom Bags with Folded Head

The »Air Free« block bottom bag is converted into a block pack by folding and flipping the top. After this, a sealable label is attached to the folded top, enabling the bag to be partially emptied and resealed.
