Flexible Packaging

← Back

The term “packaging” is used in two values. First, it is materials, objects or devices that are used to ensure the safety of goods and raw materials, their movement and storage. In other words, these are the materials, objects and devices from which the packaging is made or which itself serves as packaging. And secondly, it is a process (a set of events) that prepares goods and raw materials for storage and transportation, and also provides safety by placing them in the specified materials, objects or devices.

In this article, we will talk about the first meaning of the term, namely, flexible packaging. Moreover, it will be a question of some types (types) of flexible packaging, and not about the most flexible packaging as a whole (the features of flexible packaging and differences from rigid packaging will be discussed in another article).

Flexible packaging is a plastic material from which a container of any shape or size is formed, adapting to external action by compressing or expanding without losing its functions to preserve the product. Accordingly, packaging made from such a plastic material will also be called flexible packaging.

There are two main types of flexible packaging: a wrapper and a bag (sack). A wrapper is a material that has not been given a packaging form. It simply wraps around the item to be stored, and is held in such a way in one way or another (twisting, clip, clip, etc.). In a package (bag) the material is given a definite form either in advance or at the time of packing the product.

If we consider polymer films and composite materials (laminated foil and paper) as the main materials for making packages (sacks) that allow the formation of such packages (sacks) both in advance and at the time of packing in them the product.
