The market of polymers: why prognoses do not prove to be correct. The problem of use of polymeric packing materials directly is connected to price “boom” in the world market crude oil. In article the analysis of the different factors (demand, stock rate, idle capacities of production, free capacities of processing) on change of the prices on oil and oil-product. The consequences of influence of increase of the prices on petroleum on volume of production and price for the basic polymeric materials and their homologues are given.
Barrier Films (types, properties, markets) Barrier in packaging can be defined as the ability of a mono or multilayer structure to stop/ or reduce the transmission of gases (oxygen, nitrogen, CO2), flavors, aromas, water vapor or even ultra-violet light between the inside and outside of the package. Glass-like barrier levels are impossible to achieve in flexible packaging, but many multilayer laminated or coextruded structures are ideal high barrier solutions to keep the integrity of food packages (meat, cheese, etc.) and of many other non-food applications (greenhouse films, industrial goods). This article will concentrate on markets and applications of flexible barrier packaging films produced by cast or blown film extrusion, also known as polyolefin based barrier films.
Packing for cosmetics (modern lines of development) In article the data on development of production of cosmetic production in the world and Ukraine are given. The author determines the tendencies of such development, which determine development of packing for cosmetics. The general requirements to packing for cosmetics are considered. The author results the data on development to glass, polymeric, aerosol packing in the world and Ukraine. In clause their advantages and lacks are described. The tendencies of development of packing for cosmetics in Ukraine are determined.
The requirements to processing and packing of tinned products (experience of USA) Market of the USA by virtue of the attractiveness (large capacity, presence of large group of users, cultivate on soviet traditions of grocery stores) it must be good studied from point of comparison with national requirements. The purpose of this article is informing of researchers and producers in relation to requirements and rules, set the normative acts of the USA to packing of faintly acid and acidulated products in an air-tight container.
Singularities of shaping of goods by injection moulding The process of shaping of structure of a material of an goods by injection moulding is enough composite. For deriving an goods of a call-off quantity it is necessary to know not only technologies characteristics of a plastics, the injection machine and moulds but also to understand character of their interaction to know how to drive them during shaping structure of a material of mould piece. In this article are given the analysis of process of shaping of structure of a material of goods and the cases of anisotropy of structure of mould pieces.
Thermodynamical coordinates during pack up of aerated beverages In article the features of stages of preparation of glass tare to immediate pack up of aerated beverages are considered. In modern packing automatic devices find practical realization physical influences on the basis of vacuum blowing and technologies of sharp change of pressure. Their consequences is aseptic preparation of internal volume of bottle and their cooling. Delete of air with such constituent as oxygen from bottles provides colloidal firmness of beer, champagne, aerated drinks.
Arrangement of stream-oriented transport systems Stream-oriented transport system on the enterprises of food industry is a buffer area which smooths out contradiction between stream-oriented principle of production of goods and periodic shipping of this products an external transport. The decision of task of coordination of the modes of operations of lines of productions is achieved because facilities of multiplying freight units transform a freight stream without the change of his intensity. In this article the analysis of rrangement charts of stream-oriented transport systems of food productions and method of determination of the productivity is resulted taking into account the coefficient of transformation of freight stream.
Component errors of dosing dry products The linear metering devices occupy a leading position in a segment of dosing technique for dry products. The methodology of perfecting of metering devices is called to reduce time to development of new metering devices and examination of their performances, guessing a comprehensive approach to projection. In this article the procedure of projection of linear metering devices by measure of a given exactitude grounded on classification most typical both dominating errors and their successive analysis is offered.
Rigid household wastage ( market - state, problem and perspective) The wide application of secondary raw material in production of industrial production carries on to a raise of effectiveness of use of a fixed capital, saving of human resources, cutting of the rates of flux of auxiliary materials, fuel and electric power. Now in Ukraine in conversion with a wastage the system organized by the Ukrainian manufacturing - ecological unit on bar and use of secondary material resources «Ukrvtorma" operates. In this article the outcomes of economic activity "Ukrvtorma" are given and the wishes for a raise of an overall performance of unit and all system on conversion with a wastage are explained.
Mechanical properties of plasticses by basalt filler on the basis of second PETF Today enough perspective is making of Injection goods of the construction setting with high mechanical properties materials of compositions on the basis of second PETF from filling of matrix by a basaltic fibre. In this article the results of researches are resulted on determination of influencing of dispersion of second PETF and maintenance of basaltic filler on mechanical properties of composition material it is set that in Ukraine the production of such plasric materials of compositions has large economic aspects.
