Abstract
Sposób wytworzenia cienkościennego opakowania z polipropylenu PP z etykietą polipropylenową metodą formowania wtryskowego poprzez wtrysk do wnęki formy od strony wewnętrznej przez stempel, po czym otrzymuje się wypraskę, charakteryzuje się tym, że mieszankę polipropylenu PP o wskaźniku płynięcia MFR od 53 g/10 min. do 70 g/10 min., poddaje się reakcji chemicznej w temperaturze od 220°C do 250°C pod ciśnieniem wtrysku wynoszącym od 900 bar do 1000 bar, w czasie od 0,23 do 1 s. Czas chłodzenia wypraski po dotłaczaniu wynosi od 0,7 do 1 s, a temperatura usunięcia wypraski z gniazda wynosi od 100°C do 110°C. Korzystnie, gdy wtrysku dokonuje się w punkcie przecięcia osi symetrii wypraski. Opakowanie cienkościenne w postaci pojemnika o kształcie owalu posiadającego kołnierz (1) na całym obwodzie korpusu oraz usztywniające żebra (1A) charakteryzuje się tym, że żebra (1A) usytuowane są na spodzie kołnierza (1).The method of producing thin-walled polypropylene PP packaging with the polypropylene label by injection molding by injection into the mold cavity from the inside through a punch, after which a compact is obtained, characterized by the fact that the PP polypropylene mixture with an MFR flow index of 53 g / 10 min. up to 70 g / 10 min., subjected to a chemical reaction at a temperature of 220 ° C to 250 ° C under an injection pressure of 900 bar to 1000 bar, for a time of 0.23 to 1 s. The cooling time of the compact after injection is from 0.7 to 1 s, and the temperature of removing the compact from the socket is from 100 ° C to 110 ° C. Preferably, the injection is carried out at the point of intersection of the symmetry axis of the compact. Thin-walled packaging in the form of an oval-shaped container having a collar (1) around the entire perimeter of the body and stiffening ribs (1A) is characterized in that the ribs (1A) are located on the bottom of the collar (1).
