For a wide range of products, when it comes to packaging and making items easy to store and transport, keeping them fresh and free from contamination is a key factor to consider.
In recent years, producers in the food package, medical and pharmaceutical industries, and technical product manufacturers have increasingly turned to flow wrapping for packaging and to protect their products.
Flow Wrapping
In flow wrapping, the product moves horizontally along a machine, then wrapped in film and sealed at either end by horizontal flow wrapping machines.
When your product is flow-wrapped, you end up with a similar bag to what a Vertical Form Fill Seal service produces. Flow wrapping is also called horizontal bagging, pillow-pouch wrapping, fin-seal wrapping, and crimp-seal wrapping.
Any solid item that can be pushed along a horizontal belt is suitable for flow wrapping. Any product that needs to be put into a bag that can ultimately be pushed can be flow wrapped, including:
Flow wrappers are “popular because they’re simple and make an attractive package. Flow wrapping can preserve your raw material and offer protection. Good flow wrapping restricts the packaging around the product so that it won’t move much in the package and be disturbed. The material used to seal the pack is also kept to a minimum so that the tails aren’t too long.
This means the pack can be neatly placed in outer packaging, reducing the number of resources needed and aiding transport. Flow wrapping can also be combined with gas flushing. Gas flushing helps preserve your food by injecting a nitrogen mix into the pack. This displaces the oxygen in the bag.
Flow Wrapping of Edibles
Packaging materials for a flow wrapper are made of the following plastic films:
It is a BOPP Coex film grade with a matt surface. The matt finish reduces transparency and may boost the luxury appeal of your product. BOPP matte film is available in a low seal grade. This film is being used both on horizontal (HFFS) machines for flow wrapping and vertical (VFFS) packaging machines.
This film is made with a common polyester family’s thermoplastic polymer resin. It is often used for containers of liquids and food.
PE film is the most common plastic film in use today. It has several key usages including plastic packaging.
BOPP matte film is highly preferred for flow wrapping in these plastic films due to its extreme versatility, durability, stiffness, transparency, sealability, and barrier properties.

A horizontal flow wrapper helps to preserve and protect a wide range of products by providing a tight seal against oxygen. Gas injection technology can also be used to help produce a protective atmosphere to increase the shelf life of products.
Flow wrapping also helps to restrict the movement of a product within the packaging, preventing it from being disturbed or damaged.
Flow Wrap Packaging
Flow-wrapped products can be packed neatly, whether in outer packaging for transit or storage or displayed on a retail shelf, without the need for extra resources.
Flow wrapping allows products such as food products to be sold in smaller quantities rather than sold in bulk. As a result, selling smaller units leads to increased margins and creates added value from products.
An automated flow wrapping system allows businesses to quickly react to customer orders and achieve complete packaging of even considerable orders in a short period of time.
As a result, short lead times can be met, making businesses more appealing to customers and helping them to grow by packaging larger volumes of products.
Flow-wrapped products provide excellent opportunities for increased branding. BOPP matte flow wrap films offer customers an unobstructed view of your products. Optimal for produce packaging, these films can increase product visibility and improve retail sales.
Customized BOPP Flow Wraps
Flow-wrapped products benefit from an added layer of protection from outside contamination. This contamination can be in the form of dust, moisture, or harmful UV rays. Flow-wrapped products also benefit from less direct handling.
This limits “pick through” damages that can occur at retail. For products within the food, pharmaceutical, and medical industries, protecting products from outside contamination is extremely important for the safety of the consumer or end users. Flow wrapping provides a protective barrier and seal.
BOPP matte films are designed to run high speed over wrappers or flow wrap machines. BOPP matte Horizontal flow wrapper film is usually a hot sealing type. BOPP matte film is widely used in flow wrapping due to the following properties:
