The production process of geomembrane is divided into two types: one is calendered film, the other is blown film process

Due to the different production processes of geomembranes, the geomembranes produced have their own advantages and disadvantages:

1. Calendering geomembrane production process:

Calendered film, also known as lamination film, is a plastic film produced by hot melt cast extrusion of polyethylene raw materials.

The advantage of the geomembrane of the calendering process is that the surface brightness is high, like a mirror surface, and the price is cheaper than the geomembrane of the blow molding process; disadvantages: the thickness is uneven; the strength of the materials used is not high and it is brittle.

2. Production process of blown film:

Blow molding, also known as blown film, refers to heating and melting polyethylene plastic particles and stretching them into film by air cooling. Plastic processing technology for blown film.Anhui Zhonglu (www.zlgeo.com).

The advantages of geomembrane products produced by blow molding process are stable quality, uniform thickness, high vertical and horizontal tensile strength, and long service life. The disadvantage is that the price is higher than that of the calendered geomembrane because special materials can be used for blow molding.
