Plastic sleeve: characteristics, application

The Most common types of packaging are made from polyethylene film. It is popular and packs t-shirts, and materials for wrapping products. However, in terms of convenience, the best option is package in sleeve. Its advantages include the possibility of using material of different lengths. That is, in a way, the user can vary the parameters of the package. At the same time, a plastic sleeve retains all the advantages of classic packages, which include strength, ease of handling and to ensure the tightness.

Which uses a sleeve of polyethylene?

The Film is a basis for further manufacturing of packages. So it can be called universal. The sleeve may be consumable in the construction industry, providing catering, and in household economy. As a rule, plastic sleeve for packaging used where you plan to work with large volumes of product or product. For example, for packaging bulk materials. The absence of pronounced seams and perforations allows automatic packing line, which does not need to connect operators.

Applies the film in the form of a sleeve and in specialized areas. So, there are polyethylene, originally designed for use in electrical purposes. With this package you can isolate devices to protect them from moisture. Also distributed plastic sleeve for seedlings, which are increased requirements from the point of view of ecological purity.

Production Technology

Again, the polyethylene initially is the raw material for the manufacture of bags with handles and other specialized or household containers. The sleeve in turn is derived from the General process of film material. For its production using plastic pellets with defined quality characteristics. In the process of melting formed plastic sleeve for packaging in the form of a film. In the future, manufacturers can divide the roll into segments, creating prefabricated for a bag with handles.

In order to enhance the strength of the manufacturers also contribute to the primary composition of special additives, plasticizers and modifiers. In the result, the plastic sleeve takes high quality tensile strength. Technological process may include printing and the creation of folded inserts. But such operations usually are performed on special orders.

Features

Along the length of the packing is usually not fixed – the sleeve is available in solid form. As for width, the most common formats 20, 30 and 40 cm, although depending on the capabilities of the equipment this corridor sizes may increase. The thickness of most films within the range of 30-200 mm. Despite the thin structure, a plastic sleeve can withstand heavy loads - a few dozen pounds. It is noteworthy that the materials made from recycled polyethylene, are thicker layers that leads to high strength.

Operational properties of the film

As already mentioned, the technical features of polyethylene are determined to a large extent the additives that are added during the manufacturing process. In particular, moving modifiers to give the material a lower coefficient of friction. This simplifies the opening of the sleeve, gives the film a specific Shine, but at the same time, eliminates static effect. Specifically to prevent sticking of the interior walls of material used also antibioticbuy supplements. With such addition the film does not just gets rid of the clumping effect, but acquires a roughness of the surfaces. Widespread and means of ensuring external security, which is complemented by a polyethylene film. The sleeve, in the treatment which used the flame retardant, for example, are resistant to fire. The principle of fire suppression is implemented by introducing layered silicate composites, which form a carbonaceous layer. The result is a fire barrier and separation of volatile products during combustion.

Material Cost

Typically, manufacturers price individually, focusing on the parameters of a particular order. The cost depends and the size of the web, and the thickness and performance properties, which are endowed with plastic film. Price rolls of a width of 15 to 150 cm in average 180-200 rubles per 1 kg. the thickness can vary from 40 to 120 microns. More of the same thick film can increase the price tag on 50 roubles for kg, but here much depends on the amount of the order.

The Distributed and small sized products in the form of sleeves width from 6 to 15 cm With such a film it is possible to form a small filling bags at food service establishments. However, there are many industrial enterprises, which uses a small sized plastic film. The price in this case is 250-300 rubles per 1 kg. increase in the cost due to the complexitythe manufacturing process of coils with small width.

Conclusion

Using practical material from polyethylene to provide mechanical protection of the product and to protect it from exposure to high temperatures with humidity. While technologists tend to and new performance of the material due to the improved modifiers. In particular, if you plan to use plastic sleeve in places exposed to sunlight, you should pay attention to the content in the structure of stabilizers. So, if the film is sold to cover greenhouses, the sun will not harm heat resistant coating. Conversely, to maintain the elasticity and strength in low temperatures, you should use the wrap, which provides cold-resistant additives.
