Exploring the Applications of Four Side Seal Bag Flow Wrappers

In this blog, the Record Packaging Solutions team are sharing their thoughts on four side seal bags — so, what are they, and how can we help your business to use them?

What is Flow Wrapping?

Flow wrapping is a high-speed packaging process in which products are placed on a sheet of film or paper, which is then sealed around each product using heated jaws and cut to size. This can be done using a horizontal or vertical flow wrapping machine, depending on product specifications. Flow wrapping is used in a wide variety of industries, as the modular machinery is particularly adaptable and versatile.

The Benefits of Four Side Seal Flow Wrapping

Four side seal wrappers are a specific style of flow wrapper — a flat package, sealed on all four sides. Offering flexibility and superior product protection, this style allows full product visibility, ideal for food products like sliced meats or cheese. Four side seal wrappers can also be used for Modified Atmosphere Packaging (MAP), in which the atmospheric air is replaced by nitrogen or carbon dioxide to slow down the process of decay.

Four Side Seal Bags: Industries and Applications

Four side seal wrappers can be adapted to include easy open reclose strips, or seal strips, to help prolong the life of the product. Due to the portable nature of this packaging, it can be utilised in almost any industry — it is ideal for sample-sized items, can accommodate multi-use and closable options, and can also be easily sterilised (ideal for medical settings). The accessibility and ease of four side seal wrappers make them a popular choice for businesses of all types worldwide.
