Food printed packaging film
is a versatile material used to wrap and package food products. It consists of a flexible film substrate made from a material that resists water and oxygen penetration. It also features a pair of major faces on which a printed image is applied. This film is then covered with a barrier coating made of a water vapor-impermeable organic film forming material.
The film may be made from a variety of synthetic materials. A common choice for this application is polyolefin shrink film, which is FDA-approved and is highly durable. It offers high seal strength and puncture resistance, as well as high levels of clarity. It can also be perforated and is widely used in food packaging.
Another material used to produce food printed packaging film is shellac. This substance has a long history of food preservation and is often applied to fruits like apples. This helps prevent decomposition of fruit by atmospheric oxygen and moisture. It also improves the barrier properties of flexible food packaging film. A shellac barrier coating is inexpensive and easy to apply.
Food printed packaging film can have a printed image applied to the inside or outside of its major face. The images can be purely fanciful or contain useful information. Printed images on food packaging film are usually applied to the inside major face of the substrate. The outside face of the film will be the view of the consumer.
The most common method of printing packaging film is rotogravure printing. The process involves marking an image with a series of dots on a steel roll and transferring the ink to the film when it contacts the film. The depth of the dots can be adjusted for tone control. Excess ink is removed using a doctor blade.
Flexible film packaging is an excellent option for companies looking to increase shelf space and appeal to new audiences. It also has the added benefit of reducing waste due to spoiled food. This film material also helps reduce shipping costs. For example, it is possible to create single-serving portions, which saves money and resources.
A barrier coating on a food product can also improve shelf life. It provides greater protection against moisture and oxygen, and it improves visibility in a display case.
