Thermoresistant films

Shrink films are called films that have the ability to contract in the longitudinal and transverse directions under the influence of temperatures higher than the softening temperature of the material and after tightening the packed objects to maintain the newly obtained (shortened) shape.

Due to these properties, such films are widely used in various industries, where the manufactured product requires group (or individual) packaging.

Unlike other types of product packaging, such as cardboard, wood, plastic, etc., shrink film has several advantages:

• tightly presses the packaged products to each other, preventing them from rubbing or beating against each other during their transportation;
• Reliably protects the packaged goods from atmospheric precipitation, dust, dirt and other undesirable environmental factors while maintaining the appearance of the product itself and the label on it;
• due to transparency, it ensures the aesthetics of the package and its information content if the primary package carries any information about the product;
• due to its strength and other physical and mechanical properties, it requires a very small amount of material to form one or another package, which in turn gives significant savings in money spent on packaging;
• The recycling of used film is widely developed throughout the country, due to which there will always be an enterprise that will gladly buy your used film for quite decent money, which in turn will have a beneficial effect on the cost of goods.

JIZZAX POLIMER PLAST LLC produces polyethylene thermoshrinkable film of various types and types:

• Thickness is from 20 microns to 200 microns;
• Width from 20 cm to 100 cm;
• In the form of: linen, sleeves, half-sleeve;
• Top grade (transparent);
• First grade (with the addition of recycled materials).

Depending on the applied special grades of raw materials and technological methods, the Shrinkage coefficient can vary taking into account the needs of the consumer:

• in the longitudinal direction from 25% to 60%;
• in the transverse direction from 10% to 30%.

Film for greenhouses.

The service life of a greenhouse film depends on the intensity of exposure to ultraviolet rays of the Sun. As a result of exposure to ultraviolet radiation, the molecular bonds of polyethylene break with time, the film loses its elasticity, strength, becomes brittle and collapses under the influence of wind. Depending on the weather conditions prevailing in a given year, on the geographical latitude of the region of use, i.e. on the number of sunny days, the service life can vary significantly. So, in the southern regions of our country, a greenhouse film without special stabilizing additives (not stabilized) usually stands for no more than 4-5 months, after which it collapses and becomes unsuitable for further use.

In order to extend the service life of the greenhouse film, JIZZAX POLIMER PLAST LLC produces stabilized premium greenhouse film. In appearance, it does not differ from non-stabilized, as special additives are transparent and have no color.

In the production of stabilized film, special technological additives (stabilizers) are introduced into high-pressure polyethylene, which add additional qualitative properties to this type of film. The introduction of stabilizers into the film increases its resistance to the harmful effects of ultraviolet radiation, resists irreversible dusting, as a result of which it maintains translucency, elasticity for a long period of time, its service life is significantly increased and can reach two to three years of continuous operation.

In recent years, interest in this type of film among farmers is constantly increasing. Despite the fact that the use of expensive additives in the production of stabilized films increases its cost and, consequently, the sale price, the additional costs incurred by consumers more than pay off by increasing their service life and increasing yields.

The film is made in the form of:

• sleeves with a width of 2000 mm (in a turn of 4000 mm)
• half sleeve (sleeve cut from one side) with a width of 2000 mm (in a turn of 4000 mm)
• Film thickness: 80 microns, 100 microns, 120 microns, 150 microns.

Low-Pressure Polyethylene Film (HDPE)

Low-pressure polyethylene film (HDPE) is made from high-density low density polyethylene. Films made from this material fundamentally differ in their properties from films from high-pressure polyethylene.

Films based on low-pressure polyethylene are more rigid, durable, and crisp to the touch. The softening temperature of HDPE is higher than that of LDPE, (110 ° C), so it can withstand steam sterilization. Frost resistance up to minus 60 degrees Celsius. Such films have a higher tensile strength, but are weaker in puncture and also in tearing than LDPE films. Due to the increased strength indices, in many cases for the same purposes, it is possible to use HDPE films 2-3 times thinner than LDPE films. Accordingly, material costs, in this case, are reduced by 2-3 times. The permeability of HDPE is lower than that of LDPE, about 5-6 times, so it is an excellent barrier to moisture.

In terms of chemical resistance, HDPE also surpasses LDPE, especially in resistance to oils and fats. With increasing density, the solubility in organic solvents decreases, as does the permeability with respect to solvents.

Due to these properties, a low-pressure polyethylene film (HDPE) is successfully used instead of parchment, since the costs in this case are significantly reduced. Such a film is widely used for packaging molded products such as floorboards, baseboards, plastic panels, etc.

Low pressure polyethylene film (HDPE) is made to order in the form of:

canvases
sleeves
half sleeve
Film sizes may vary:

1. Width from 10 cm to 90 cm
2. In thickness from 10 microns to 100 microns in increments of 1 micron
