Flexible packaging is made from materials that can be easily deform and return to their original shape just as easily, without getting damaged. Another characteristic of this type of packaging is that it can be molded onto the product, taking its shape, combining functional and aesthetic roles. In addition, flexible packaging from a digital printing Colorado company significantly reduces transportation costs and increases shelf space.
Here are some of the features of flexible packaging:
It is absolutely necessary that the packaging keeps the product safe during transportation, and stays closed tightly while the product is being handled.
Water/ humidity barrier
It is known that in the case of certain products, the packaging must not allow water or humidity infiltrations to the product, in order to preserve its quality. The best material in this regard is aluminum, but it can be replaced by polypropylene, polyethylene or polyester.
Oxygen barrier, controlled atmosphere
Flexible packaging can keep the freshness of the products longer, because they allow the oxygen to be removed from the package and replaced with a mixture of gases, CO2 + N, which helps to extend the shelf life. The material that provides a total gas barrier is, once again, aluminum, but where it cannot be used it can be replaced by metalized PP, metalized PET etc.
It is known that fats rancid in the presence of UV rays. To counteract this phenomenon, a special foil can be easily inserted into a flexible packaging structure to prevent the penetration of light.
