Recovery and utilization of packaging


PP and PE (or AA) and the PE composite with aluminum foil for chocolate,[link widoczny dla zalogowanych], fast food such as soup and tea packaging a11. BOPP and PE (or AA) PVDC cellophane, and the PE composite, advanced packaging for cooked meat. 12. BOPP and PE (or AA) and paper and composite PE for tea packaging. 13. BOPP and PE and EVA compound for ice cream packaging. 14. Vacuum metallized BOPP film, used as decorative materials and ice cream packaging. Production method for producing biaxially oriented polypropylene, there are two main methods. A method for the tenter. About raw materials by heating in the T type die out into a thick film after the heat at a certain temperature for both horizontal and vertical stretch leek, in order to achieve the orderly arrangement of molecules in the film's purpose. This method has the advantage of uniform thickness produced the film, you can control, in addition to individual can be used as packaging materials, plastic film can and a variety of other phase compound to make composite materials for a variety of purposes, leek with a sealing sex. High production rate of this method is suitable for mass production. Drawback for the production of large one-time investment of equipment. Another approach is blown (or pipe-bubble. This method will melt extrusion of resin or plastic material blown out by the thick-walled ring after the model prototype tube, the horizontal stretch by the compressed air in a controlled Inflation temperatures in order to obtain transverse tensile direction, the same time, enhance the take-up device in the vertical (ie,[link widoczny dla zalogowanych], machine direction, MD) sequential extraction stretching direction. drawback of this method is not for the high rate of production, so production than the previous method is less; another uneven film thickness, as a single packaging material is beyond reproach, it is difficult to rent the other plastic film composite into composite materials meet the quality requirements, limited by the rule of law into the BOPP film applications. But the production one-time investment in equipment smaller, easy-to-be launched. According to the material at our disposal shows that most of the foreign industrialized countries use the first method of production, that is, after T mold out of the mechanical way tenter method, product quality requirements of Taiwan, almost . This is a widely used, high efficiency and production volume production methods; it is also a strong adaptive approach, it is easy to produce different thickness requirements of coral I BOPP film. On the pull amplitude method PP film (BOPP) and PP pipe-bubble film (IOP) and technical indicators of the characteristics of the comparison, see Table 4. BOPP film suggested the only drawback is that sealing is poor. but it can be remedied If and PVDc film composite,[link widoczny dla zalogowanych], may improve the sealing, while oxygen barrier, c02, and steam water blocking performance can be improved, for (continued on page 19) on the China Packaging 199o 1o No. 1 / 1989 ships Eurostar recorded EurostarPackagingCompetition'89 packaging competition winners sponsored by the European Packaging Federation 1989 Eurostar package design selection activities in 1989} O 26 in Milan, Italy. from European countries in 37 entries . won the Eurostar Competition Honor Award and the works of the eight. all the winning works in Milan Packintec what-installed exhibition (November 7El-l】 E1) on to the display. from the United Kingdom.
