Flow Pack packaging machines get their name from their packaging technique.
The materials to be packaged, in fact, are aligned and 'flow' one by one on a belt to be heat-sealed by a film: the products are wrapped entirely in a plastic film (standard or recyclable) and finally closed by a sealing bar.
The kind of bag we get will be similar to the one produced by a vertical packaging system (VFFS).
This packing system involves a mass-production in which rollers and reels move, fill, seal, and cut sheets of plastic material.
Four tasks are performed in one continuous operation.
The pouch can be closed in different ways: with or without weldings, with or without modified atmosphere injection (MAP).
The MAP packaging allows to extend the shelf-life of the product, protecting it from dust and atmospheric agents that could compromise its integrity and quality.
Packing rates are quite high. As well as being very secure, the packaging is also aesthetically pleasing, making it the ideal solution for off-shelf products.
Flow pack wrappers (HFFS) represent an increasingly popular choice for their speed and precision.
Flow Pack packaging is part of the horizontal packaging.
The pouch thus obtained will have the shape of a pillow.
A tab may be present close to the longitudinal weld. Each package requires the creation of three seals and a fold.
The horizontal flow pack packaging machine is recommended for medium-large productions.
Different types of film can be utilized. Thick or thin, compostable or recyclable. Particularly, polypropylene and polyethylene.
This is especially popular because it is lightweight, nontoxic and extremely durable.
The speed of flow packing varies depending on various factors including machine type and package size: average speed of packaging from 40 to 60 pieces/minute.
The Flow Pack packaging is used in various sectors. Its versatility makes it an ideal solution and extremely popular in many area sas:
In particular, it is used in the food industry and in the packaging of typical products such as snacks, bars, baked goods, nuts, chocolate, and many other food products. For example, over-the-counter mini flow packs are very common.

Whether you’re a seasoned packaging professional seeking to optimize your processes or a newcomer exploring the packaging landscape, understanding the intricacies of flow wrap packaging is essential.
In this comprehensive guide, we delve into the world of flow wrap packaging, unraveling its core principles, exploring the myriad benefits it offers, and shedding light on the types of materials that suit various products.
Flow wrap packaging, often referred to simply as “flow wrapping,” is a packaging technique that has gained widespread popularity due to its ability to meet these essential criteria.
Flow wrap packaging is a versatile and highly efficient method used to package a wide range of products.
Also known as horizontal form-fill-seal (HFFS), this process involves wrapping a product in a flexible film, creating a tightly sealed package that showcases the item while providing protection and tamper resistance.
It’s a continuous process where products move horizontally through the machine, passing through various stages, including film unwinding, product loading, sealing, and cutting.
At its core, flow wrap packaging consists of three primary elements:
The packaging film, typically made from materials like polyethylene (PE) or polypropylene (PP), is supplied on a roll. This film is crucial as it forms the protective outer layer of the packaged product.
This is where the product to be packaged is introduced into the flow wrap machine. It can handle a variety of items, ranging from food products like chocolates and granola bars to non-food items like soap bars and disposable razors.
In this section of the machine, the film is sealed around the product, creating a tight seal. Simultaneously, the excess film is trimmed or cut off to ensure a clean and professional appearance.
One of the standout features of flow wrap packaging is its versatility.
It is suitable for a diverse array of products, making it an ideal choice for manufacturers in various industries. Some common applications include:
Food Products: Flow wrap is commonly used for packaging bakery items, snack bars, fresh produce, and confectionery products.
Non-Food Items: Beyond food, flow wrap is employed for packaging items like toiletries, pharmaceuticals, and promotional materials.
Flow wrap packaging is a packaging technique that comes with a host of advantages, making it a preferred choice for many industries. Let’s explore the key benefits it offers:
Efficiency is at the core of flow wrap packaging. The continuous and automated nature of the process reduces labor costs and ensures high-speed production.
This efficiency translates to lower overall packaging costs, particularly when handling large quantities of products.
It also minimizes material waste since the packaging film is precisely cut to fit each product.
Flow wrap packaging provides excellent protection for products.
The tight seal formed around the item not only keeps it secure but also guards against external contaminants, moisture, and tampering.

This makes it an ideal choice for packaging items that need to maintain their quality and freshness, such as food products.
Flow wrap can handle a wide range of product shapes and sizes.
From irregularly shaped food items to standard-sized non-food products, flow wrapping adapts seamlessly.
This versatility allows manufacturers to package various products on the same production line without the need for frequent adjustments, saving both time and resources.
For products requiring tamper-evident packaging, flow wrap is an excellent choice.
Once sealed, any attempt to open the package is evident, providing consumers with peace of mind that the product is secure and has not been tampered with.
Flow wrap packaging can also contribute to prolonging the shelf life of certain products.
By creating a barrier against oxygen and moisture, it helps prevent spoilage and extends the freshness of food items. This can lead to reduced food waste and improved product quality.
As sustainability becomes a more significant concern, flow wrap packaging can be adapted to align with eco-friendly packaging practices.
Manufacturers have the option to use recyclable and biodegradable films, reducing the environmental impact of their packaging.
Flow wrap machines are known for their high-speed production capabilities.
This rapid packaging process ensures that products can be packaged quickly, meeting demand and keeping production lines running smoothly.
Automation in flow wrap packaging reduces the need for manual labor. This can result in cost savings and improved consistency in packaging quality.
Different products have distinct requirements, and the choice of material can impact the packaging’s functionality and appearance.
Let’s explore some common types of flow wrapping materials:
Polyethylene is one of the most widely used materials in flow wrap packaging.
It’s known for its flexibility, clarity, and excellent sealing properties.
PE films come in various thicknesses, making them suitable for a wide range of products. Low-density polyethylene (LDPE) is often chosen for packaging items like bread, vegetables, and textiles, while high-density polyethylene (HDPE) is used for heavier or bulkier products.
Our PE sealants are a blend of both HDPE and LDPE. We have selected these films for their excellent seal initiation and tackability and well as their ability to seal through contamination
BOPP films are a subset of polypropylene films that have been stretched in two directions to enhance their strength, clarity, and barrier properties.
BOPP films are commonly used for packaging products like candies, cookies, and greeting cards. They offer a glossy, high-quality appearance that is visually appealing on store shelves. BOPP is also known for its lower cost compared to other film types.
Polyester films are known for their strength, durability, and exceptional clarity.
They are often chosen for packaging products that require a high level of transparency, such as fresh-cut fruits and vegetables, sandwiches, and salads. PET is our typical print film for its excellent clarity
PET films provide an excellent barrier against moisture and oxygen, preserving the freshness of the contents. PET doesn’t have much OTR barrier and is also not great on MVTR barrier. We use PET for its clarity and dimensionally stability as printing web for graphics. We also laminate PET with a more functional film such as PE (to add sealing) or METPET/EVOH (to add oxygen and moisture barrier)
Cellophane is a biodegradable and compostable packaging material made from wood pulp.
It offers a unique, natural appearance and is often used for wrapping items like chocolates, gift baskets, and artisanal products.
While cellophane is less common in industrial packaging, it is favored for its eco-friendly properties.
Metallized films are used to add a metallic or reflective finish to flow wrap packaging. Mainly they are added for barrier properties, metallic finish is a secondary use.
They are often seen in products like snack bags and specialty food items, giving them an eye-catching appearance.
Metallized films can also provide added barrier properties, protecting products from external factors like light, moisture, and oxygen
As environmental concerns continue to grow, manufacturers are increasingly turning to recyclable and sustainable flow wrap materials.
These may include films made from bio-based plastics or recycled materials. (We don’t have bio-based ready to go at a commercial level). in choosing such materials can align with sustainability goals and appeal to eco-conscious consumers. Our Recyclable PE/PE structures and our PCR (post consumer recycled) structures can fall into recyclable and sustainable films
All of the film we sell is laminated and made up of 2 to 3 films.
They are suitable for products that require tailored packaging solutions.
When selecting a flow wrap packaging material, consider factors like the product’s characteristics, required barrier properties, and desired shelf presentation. Our sales team will help answer any questions a customer has and walk them through what kind of film they need for their application
It’s also important to ensure the chosen material complies with any regulatory requirements specific to your industry.
