Packaging solutions

Logogroup factories specializing in the manufacture of plastic packaging of varying complexity, with barrier materials of various types. This includes lines for blowing a polyethylene sleeve, a polypropylene film and a film of combined materials - polypropylene / polyethylene / polyethylene tetraflate / foil / paper. 

The basic packaging technology has not changed for many years, improving in detail. One of the directions of development is the improvement of the components of the polymer resin. This includes a range of additives and additives for changing and adjusting packaging properties.

The most common way to make plastic packaging, for example, from polyethylene, is called film extrusion or the “tubular film process”. The production process may differ depending on a number of nuances, for example, original or secondary raw materials, such as density of blowing polyethylene or film structure, but the general essence is the same and the whole process consists of preparing the mixture, blowing, cooling, applying the image and cutting / soldering the finished packages.

The starting stage (1) in the production of a polyethylene sleeve is the preparation of raw materials. Polyethylene is introduced into production in granular form, which is called resin. Raw plastic granules HDPE, LDPE or LLPDE are mixed (2) in a hopper with additional components, for example:
anti-block component - prevents blocking (sticking) during the drying phase;
slip component - helps the finished plastic bag open easier and allows sliding surfaces;
an ultraviolet inhibitor (UVI) protects the plastic from UV radiation, which can weaken the strength of the plastic under certain conditions.
A complete list of the components that the company uses, as well as mix schedules, cannot be shared. However, a general description of the process and its understanding are important for collaboration.

For each individual order, a unique mixture is prepared, depending on the desired characteristics of the package. This leads to large minimum order volumes and the inability to manufacture products in small batches.

The prepared resin is fed to extruders - special pumps for superdense liquids (3). There, the material is heated to the desired temperature and mixed. The heating temperature of the resin depends on a number of parameters and can fluctuate around 260 ° C. A material in a heated container, having reached a molten plastic state, is blown through a die into the shape of a sleeve (4). The shape of the stamp adjusts the size and thickness of the sleeve and the future package. After passing the Frostline point (5), the molten polyethylene solidifies into a film (6).

The final step of the extrusion process directs the sleeve through a series of rollers at the top of the cooling tower (nip rolls) and inserts a flattened film, which is then wound into rolls (7-8). The heights of the extrusion tower can range from 7 to 10 meters. This height is necessary for sufficient cooling of the plastic film. Further, if necessary, the film is treated with an electrostatic current wave. This is part of the film printing process (activation).

Prepared sleeves fall into Flexo machines - rotary machines for printing on flexible surfaces.

 A unique cliche is made for each order. This is another reason for the large circulation of products. 

Please note that the color components are used for the basic painting of the plytilen film (package). The addition of fast components occurs at the initial stage, before extrusion.

After the printing process is completed, the film rolls are cut into the required sizes. When cutting, the process of soldering and perforation can occur. For the manufacture of directly the products (packages themselves), the semi-finished film is fed into machines (automatic machines) with specialized equipment, where the characteristic features of each product are formed: side and bottom folds, zip locks, bonding valves, ventilation valves, reinforced ventilation holes stitches, and the like.

When it comes to finished products, rather than rolls on the finished product, it is important to understand that each type of packaging is my characteristic design features that change the package functionally. Follow our blogs in the social networks and on this site, where we talk in more detail about each type of package design and how to choose the right package.

The process of extrusion of the film to create plastic bags has not changed for many years. But what has changed is how we use plastic bags in our daily lives - when the novelty is now an everyday convenience that makes our life better.

 Logogroup is a reliable partner

Technical Information on ADX-Biodegradable Additives

Product Name: ADDITECH ® OX 004 РLL concentrate oxo-biodegradable additives.
Regulatory document: TU U 24.6-21628777-003-2007 "Superconcentrates of granular modifying additives."
Hygienic conclusion of the Ministry of Health of Ukraine SSES: 05.03.02-04 / 81620.
Carrier polymer: linear low density polyethylene.
Characteristic: heat resistance - 260 °C.
Mass fraction of moisture - ± 0.05%.
Bulk density - 0.55 ± 0.1 g/cm3.
PTR of the polymer base - 4-6 g / 10min (190 °C / 2.16 kg)
Active substances: synergistic mixture of activators of polymer degradation.

It is used to reduce the time of decomposition of waste polymeric products, primarily packaging films of polyethylene under the influence of the environment: light, moisture, elevated temperatures, mechanical stress, biological effects, etc. The concentrate contains a synergistic mixture of catalysts (degradant) of oxidative degradation of polymers, leading to the destruction of molecular chains, the complete loss of mechanical properties and the destruction of products. The resulting low molecular weight products of oxidative degradation, gradually assimilated by bacteria, is the actual biodegradation. Ultimately, water, carbon dioxide and biomass (humus) are formed, which are safe for the environment and humans.

The product does not contain toxic and abrasive particles; it can be processed at high temperatures (up to 260 °C) together with chalk and talc-like concentrates. In the case of re-processing, the concentrate can be turned off by special stabilizers.

It is used for packaging, shrink, stretch and other films, bags, garbage bags made of polyethylene, bottles, pots for seedlings, disposable tableware, etc.
