Polyethylene Film

Stretch films are widely used for the production of polyethylene film. Polyethylene is used primarily for packaging and protection products, particularly bulk goods on pallets and packaging various materials and products of large sizes. Due to the small thickness, high durability and ability to guarantee the safety of the cargo, plastic film is the most economical way of packaging different products and materials. Polyethylene film can be divided into three main types: – polyethylene film for further processing, a thickness of 40 to 150 microns. – Polyethylene film for packaging goods in special packaging machines, thickness from 10 to 40 m, roll width from 500 mm to 1500 mm. – A film for manual packaging, the thickness from 10 to 40 m, roll width 450 mm or 500 mm. In recent years, plastic film are increasingly used on industrial enterprises, retail and logistics companies – for goods on pallets.

This is due to the fact that the price of plastic film is very low compared with other packaging materials, and properties allow to keep the transported cargo. In connection with the development of external trade relations of Russia with other countries, the demand for polyethylene film is constantly growing. Plastic film is produced by fully automated, modern production lines. Therefore, the manufacture of the film can only be well equipped in technical terms factories specializing in the processing of polyethylene. The main raw material for the production of stretch film (plastic film) is a linear low density polyethylene (LLDPE).

During the heating period by enclosing parts inevitably occur heat losses, which range from 30 to 80% of the lost energy. The system enables improved thermal insulation to reduce these characteristics, and accordingly, as well as spending more than 5 times. It is not good insulated outer walls, in addition contribute to the creation of unfavorable indoor climate, condensation, resulting in is soaking building elements, as well as mold. These problems can be solved through adequate insulation of exterior walls. At warming facade cottages meneralovatnymi plates in large as reduced noise pollution. The facade of the house can be warmed in 3 ways: inner insulation, outer insulation and the insulation structure inside the wall. For the most part wish to be given to systems outside thermal insulation, as They have several advantages: protect walls from adverse environmental impacts (air, temperature, and biological); protect the walls from cooling, which prevents condensation on the inner surfaces, provide a “breathing” walls, as well as, of course, additional sound insulation, as well as long-term use.

Facade insulation systems depending on the technology falls into the following groups: – light plaster systems insulation – hard plaster thermal insulation system – ventilated facade construction. >. In light of plaster insulation systems plate heater is attached to the wall with glue and dowels, and then covered with a thin plaster layer. The total thickness of the layers does not exceed 15 millimeters. As can be seen that to the heat insulating material in front of the system presents the highest guidance. To perform qualified installation of light plaster systems require workers with relatively high qualifications, as the plaster must be applied evenly and durable layer of glass-fiber reinforcement. Plate heater in heavy plaster system is attached with steel mesh reinforcement, and anchors.

The thickness of the layers of insulation after sometimes can be up to 50 millimetrov.V this facade system, metal mesh protects the carrier topcoat of linear thermal strain. Here, as well as in the lungs of plaster systems, there are high notes on a heater. Ventilated facade system is similar to masonry with an air gap, only instead of the outer wall of various facing materials are used (boards or sheet material). Thermal insulation is fixed to the wall with the load-bearing frame, and anchor fastening system. Such a system insulation Facade provides ventilation of the inner layers, as well as promotes the removal of moisture, which saved the insulating properties of insulation and walls, as well as improves the appearance of the walls, and, importantly, increases the service life of insulation (up to 70 years!) depending on the material used. Used in modern construction of the outer insulation of houses provide an opportunity to not only effectively solve energy conservation, as well as provide opportunities to architects and designers to create a completely new image of the cottages, making them inaccessible to earlier forms.
