In transparent types, Colored, white or milky is produced.
It is used in the market with thicknesses between 25 and 100 microns.
Compared to other quality packaging films. It has a lower print.
For printing on poly films Ethylene is used more than flexo printing in Iran, and there are few printing houses that can print on polyethylene film with a roto machine.
In single-layer, three-layer, five-layer and even Nine layers are produced, each of which is used in different industries.
Polyethylene, due to its very good resistance to liquids and excellent sewing ability, is used in multi-layer materials for sealing and laminating. It is used in the inner layers.

It is the most widely used thermoplastic film among all packaging wrappers.
It can be found in the Iranian market with thicknesses between 15 and 40 microns.
Two glossy and matte models. each of them can be shell or metallized.
It has weaker sewing ability than polyethylene and CPP, but its print quality is much higher and better compared to these two. may
It is used as a printing layer and laminate layer in multi-layer materials.
In flexo and gravure printing, OPP is used to print the packaging of many food products.
Wrapper
CPP films are very similar to OPP films, but compared to OPP they have better tear resistance.
Of CPP and OPP It is used as a laminate together in products such as pasta and beans.
CPP has better sewing ability than OPP, but since it is less transparent than OPP. Yes, the print quality is not up to his feet
One layer of CPP can be used in the packaging of toast.
Polyamide wrap
With a thickness of about 15 microns, it is used in the packaging industry.
It does not have the characteristic of thermal adhesion and is laminated with a layer capable of flooding.
Characteristic It has a high level of protection and is very suitable for preserving and protecting food. The main purpose of using different grades of polyamides in the food packaging industry is to reduce permeability to oxygen and preserve the aroma. is.
Sausage packaging and Sausage is an example of the use of polyamide wrapping in the packaging industry.
The benefits of using wrapper package
