What are printed packaging films?

Printed packaging films are a great way to provide fresh packaging and protect products. These films come in a variety of forms, including shrink, barrier, and multi-layered. They are available in up to 10 colors and can be custom-printed to meet your needs. In addition, they can provide a barrier to moisture and oxygen, and can be manufactured to meet any type of sealing requirements.

There are a variety of packaging films available, including OPP, Collation shrink, and LLDPE Metallocene. These films can be printed to meet your company's unique packaging requirements. They come in rolls of various widths and diameters, making them an easy choice for custom packaging solutions.

When selecting a flexible film, look for a substrate that is at least 1 micron thick. Ideally, the thickness should be as low as possible, but it can be as high as 150 microns. The maximum thickness, on the other hand, should not exceed 5,000 microns.

In addition, when it comes to recyclability, there are a number of factors to consider. For instance, a film that is printed with a UV-resistant pigment is more likely to be recyclable than a film made of a more conventional material. Moreover, some types of films may not be suitable for every type of packaging.

In order to improve the barrier properties of their printed packaging films, manufacturers often use sealant films, also known as packaging laminates. These films provide a protective layer that prevents the ink from rubbing off and maintaining the quality of the print. Moreover, these films add stiffness to pouches and other packages.

The materials used in these films vary according to their densities. Low-density polyethylene is commonly used for preformed bags and roll stock. It is also commonly used for bulk bun lines. Both types of films are available in different gauges. The thickness of these films is measured in mils.

Flexible packaging films may contain a printed image on their interior or exterior major faces. The images may be purely fanciful or useful. They can be printed using any known printing technique, including gravure, ink jet, silk screen, and flexographic printing. Intaglio printing is also available, as is pad printing. These films also come in transparent varieties. The use of transparent packaging films can enhance the appearance of food products.

The thickness of a film is important because it affects heat sealing, printing, and mechanical strength. It is difficult to measure film thickness by hand, but can be done with a micrometer with a head of 25 mm. Another way to measure film thickness is by its basis weight, which is also known as grammage. This measurement allows you to determine the yield of the film.
