Flow Pack machines (HFFS) are increasingly becoming one of the most commonly used packaging methods.
In recent years, they have become even more popular for the packaging of all types of products, from foods to everyday objects.
According to the Future Market Insight (FMI), the global market for this industry grew by 2.9 % during 2015-2021. It is expected to reach $6.8 billion by 2032, up from $4.8 billion in 2022.
In particular, Flow Pack packaging machines belong to the single-serving packaging. Single portion packs are particularly popular because they can preserve products for a long period of time.
But what specifically is a Flow Pack? What are the benefits of Flow Packs?
In this guide we will analyze and explain in detail:
Flow Pack packaging machines get their name from their packaging technology.
In fact, the materials to be packed are lined up and ‘flow’ one by one on a belt to be heat-sealed by a film: they are wrapped entirely and finally sealed by a welding bar.
The obtained bag, will be similar to the one produced by the vertical packaging machine (VFFS).
This technique involves a series-production in which rollers and reels move, fill, weld and cut films of plastic material: 4 activities are performed in one seamless process.
The bag can be closed in various ways: with lateral and/or longitudinal sealings, with or without a protective atmosphere (MAP).
The MAP packaging allows to lengthen the shelf-life of the product, protecting it from dust and atmospheric agents, factors that could compromise its integrity, quality and conservation.
Packaging rates are quite high. Beside being very safe, the packaging is also aesthetically pleasing, this makes it the ideal solution for shelf products.
Flow pack packaging machines (HFFS) are an increasingly popular choice due to their speed and accuracy in packaging.
Flow Pack packaging is part of horizontal packaging. The sack obtained will thus have the shape of a pillow.
A tab may be present near the longitudinal weld. Each package requires the creation of three welds and one fold.
The horizontal flow pack packaging machine is particularly suitable and indicated for medium-large productions.
Flow wrapping can involve horizontal packaging lines. It will therefore have the shape of a cushion. In the vicinity of the seal there will be a tab placed in the longitudinal direction of the sides of the film. Each pack requires the creation of three seals and one fold.
Several types of films can be employed. Thick or thin, compostable or recyclable. In particular, polypropylene and polyethylene.
It is particularly popular because it is light, non-toxic and extremely resistant.
The speed of flow wrapping varies according to several factors, including machine model and pack size: generally packing speed from 40 to 60 pieces/minute.
Flow Pack packaging is used in many different sectors. Its versatility makes it an ideal and extremely popular solution in many sectors, like:
In particularly, it is used in the food industry and in the packaging of typical products such as snacks, bars, bakery products, dried fruits, chocolate, and many other food products. For example, over-the-counter mini-flow packs are very popular.
The benefits of Flow Packs over other packaging methods are:
It therefore represents one of the most reliable and versatile packaging options of the moment.
