Vacuum bag is a multi-layer flexible packaging solution that allows the product to be stored in a oxygen-free environment with the discharge of the air inside. It is preferred to maintain freshness and shelf life in the food industry; it is used in the protection of solid and liquid products such as screws, adhesives, resins in industrial applications.
How to Produce Vacuum Bag?
GKK Foil vacuum bags, coextrusion produced by method. In this method, the layer of one or multiple polyethylene (PE) is combined in one process with at least one layer of polyamide (PA). The resulting film has both high mechanical strength and strong barrier properties.
Tasks of layers
- Polyamide (PA) layer: Provides high tear and puncture resistance; lowers gas and aroma permeability.
- Polyethylene (PE) layer: The water vapor barrier acts as a layer of heat source (sealing) and stabilizes the film.
Advantages of Vacuum Bag
- It significantly extends the shelf life of food by removing oxygen.
- Due to its high mechanical strength, it reduces the risk of drilling in transportation and storage.
- Fits different vacuum machines with wide welding window.
- Protects product quality by blocking aroma and odor loss.
- Increases product visibility thanks to its transparent structure.
Thickness Options and Application Areas
GKK Foil vacuum bags 250 micron with 40 micron can be produced in varying thicknesses. The correct thickness selection should be determined according to the weight of the product to be packed, the sharp edge does not contain inside and storage conditions.
- Meat and meat products: Thicker and puncture resistant structures for bone parts.
- Cheese and dairy products: High-barrier, anti-wear structures.
- Seafood: Scent barrier strong multilayer films.
- Industrial products: Durable bags for products such as screw, mercury, adhesive and resin.
How to Choose The Right Vacuum Bag?
The main criteria to pay attention to the selection of vacuum bags are: the weight and geometry of the product, the required barrier level (oxygen/nem), the type of welding machine and the intended shelf life. necessarily in applications requiring food safety suitable for food contact bags made from raw materials should be preferred.
As GKK Foil, we manufacture vacuum bags in special thickness, size and barrier properties to your requirement. To determine the most suitable solution for your products Contact us.
