What is Plastic Foil? What Does It Do?

Plastic film is the most preferred choice in the packaging and packaging industry due to the advantages it provides. included in the materials. Plastic bag, packaging materials, food storage These foils, which are preferred as food contact materials, is produced. For this reason, plastics in the pharmaceutical sector, especially in the food sector, The use of foils is quite common.

Plastic foil, which is a thermoplastic material, goes through different production processes. casting and Extrusion is among the most frequently used processes in the production of these foils. bulk and The main purpose of extrusion processes is to give the desired thickness and thickness to the thermoplastic material. to give the desired shape. Particularly in the extrusion process, the foil is doubled. It is possible to obtain the required thinness by pulling in the direction.

What is Plastic Foil?

Plastic foil is a kind of thermoplastic material that can be produced from different raw materials. Most Although the popular raw material is polyethylene, the production process is not limited to polyethylene. Polypropylene, polyester and polyvinyl chloride are also widely preferred in the production of these foils. included in the raw materials. Also cellulose acetate, cellophane and bioplastic Innovative raw materials such as plastic foil are also preferred in the production.

Plastic foils, which have a transparent appearance, form a protective barrier between the product in the external environment. creates a barrier. The foil, which provides protection against biological agents, It also helps prevent product contamination. It is resistant to corrosion This packaging material can be used even in the harshest conditions.

What Does Plastic Foil Do?

The most basic function of plastic foil is to protect the packaged material or product against the effects of the external environment. to protect against. External effects can be polluting agents as well as humidity or sudden temperature change may occur. In many cases, plastic foil packages are at 60 to 200 degrees. It can preserve its form and properties without losing its form and properties.

The raw material to be preferred in the production of plastic foil depends on the sector in which the foil will be used. varies. For example, the moisture permeability of low-density polyethylene higher than polypropylene. In such a case, for a moisture sensitive product While preparing the packaging material, the plastic foil produced from polypropylene can be used more accurately. It will be an option.
