As a result, the rear-side film is constructed of a plurality of co-extruded layers.

The PP materials used form the core layer and the outer layers of the backing film.

These polypropylene (PP) grades form the core layer as well as the outer layers of the backsheet.

Such a rear-side film can be inexpensively produced by way of co-extrusion with layers that are directly interconnected with each other.

The total thickness of the rear-side film remaining behind the front layer is advantageously further divided into layers.

The suitability of a backsheet film to withstand certain system voltages without any great difficulty is measured by a parameter called resistance to partial discharge.

Upon request, they can be also made with black backsheet and black frames.

Our PVC Mesh Banner has 380 g per square meter (10.47 square feet) including the back film.

Inspection includes the whole panel (frame, junction box, cells, backsheet, glass)

It is of course not cogently necessary to supply the bottom sheeting web, but it is also possible to produce bags in which the front and rear side sheetings are simply welded together along the bottom edge 6b of the bag.

The closure strip furthermore is held at a second weld between front and rear side sheetings to the lateral seams 5 of the beverage container.

The technology according to the invention offers the advantage that, for example, a print on the rear side sheeting may be dispensed with, so that a working step involving very high costs in foil or sheeting production is saved completely.

The backing foil is sealed to the EVA copolymer at the outer edge of each piece at 130° C. under 27 kg.

To increase the power yield of modules we develop an optical simulation tool allowing to forecast the gain brought by using new materials (lamination foils, structured glass, back sheet).

The "solvent rub test" has proved to be a reliable test method. In this test, a cloth is soaked in the chemical and then rubbed to and fro on the backsheet 50 times with a defined pressure.

Back sheet: This back sheet consists of several layers of various high quality plastics which cannot be separated from each other.

Diaper Surface material, sap, weight, back sheet material, elastic wasit, magic tape are free to choose.

A: We use super soft non-woven fabric for the surface, anti-slip back-sheet, and imported Japan SAP as in our domestic selling product to ensure the practical apply.

As adhesive layers are not used for the backing film, the risk of delamination between the individual film layers is eliminated.

In the state of the art, solar modules are produced by the solar cells being connected electrically in series to form so-called cell strings and being laminated between the front glass, an encapsulating material and a rear-side film.

The layer system may, for example, be based on a glass substrate, which is transparent for the relevant components of the solar radiation, or a rear-face film, between which the solar cells and the electrical connectors which connect them are enclosed.

In known production methods for solar panels, some of the electrical connectors have been passed through the rear-face film to the outside in order to produce the electrical connections, before the lamination of the layer system.

A layer system is formed on this glass plate 10, consisting of a first transparent plastic layer 20 composed of ethylene vinyl acetate (EVA), a plurality of solar cells 30, which are known per se, a second plastic layer 40 composed of ethylene vinyl acetate (EVA) and a rear-face film 50 composed of polyester.

Intermediately positioned layers are in particular provided with an inorganic stabilizing filler with a weight proportion of up to 40%, relative to the total weight of the rear-side film, in order to achieve thereby higher mechanical strengths as well as an increased temperature resistance and to counteract shrinkage tendencies during the lamination process of the EVA as well as during long-term use.

Another method for producing a rear-side film that is of interest under the aspect of manufacturing costs and realizable in practice in a particularly simple way resides in the manufacture of a multi-layer blown film hose with co-extrusion of several layers of or with a polypropylene, wherein the blown film hose, after extrusion and blow forming, is deflected and laid flat across rollers or is flattened by being compressed between rollers so that the blown film hose is formed to a flat film strip by inner blocking at the inner layers that are resting on each other.

An intermediate layer of the blown film that after blocking is then repeated symmetrically in the layered arrangement in the rear-side film can in particular accommodate suitable fillers.

Both methods for producing the rear-side film, i.e., the co-extrusion of a flat cast film as well as co-extrusion of a blown film with subsequent blocking can be performed on an industrial scale in an easily controllable and also cost-efficient way and open up the possibility of providing a film based on polypropylene that remains stable and without shrinkage in particular thermally during a lamination process of the solar modules and that also in long-term use, often conceptualized for decades, of the solar module ensures weather resistance and mechanical stability as well as fixed cohesion with the EVA embedment of the solar cells.
