B, glue preparation: take polyurethane binder and ethyl ester, mix by the weight ratio of 2:3, stir;
C, dry multiple: require to get polyester volume and polyethylene volume from raw material storage according to production technology list, polyester volume is put on the unwinding rack in the middle of dry compound machine, polyethylene volume is fixed on to unreeling on support before machine, utilize roller the glue in b step to be evenly applied on the corona surface of polyester volume inner side, heat through baking oven bonding with polyethylene sheets, by extruding and the oven dry of compression roller, rolling forms composite membrane volume;
Require to get the polyester film printing volume easily tore film volume and a step from raw material store according to production technology list, polyester film printing volume is put on the unwinding rack in the middle of dry compound machine, easily tore film volume is fixed on to unreeling on support before machine, utilize roller the glue in b step to be evenly applied on the corona surface of polyester film printing volume inner side, heat through baking oven bonding with easily tore film, by extruding and the oven dry of compression roller, rolling forms print film volume;
D, inspection: the outward appearance of film: without obvious fold, no marking, without bubble and black impurity;
E, slaking: dry composite membrane of answer is rolled up and print film is rolled up to send and between slaking, utilized the slaking of automatic composite aging machine, 50 DEG C-60 DEG C of curing temperatures, curing time≤48h;
F, cut: according to manufacturing technique requirent photoelectricity cutting machine, the composite membrane after slaking and print film volume are cut into needed width by bag requirements, the friendship semifinished product warehouse that is up to the standards is for subsequent use;
G, bag: get print film volume and composite membrane volume in f step, print film volume is fixed on to unreeling on upper bracket of three side sealing bag machines, composite membrane volume puts down and unreels on support, simultaneously compressing through becoming mould type to seal through drawing-off, through cutting final generation finished product, finished product is 100 one bundles after sheet inspection is qualified, 500 a bundles, packaging is handed over storehouse, and inspection envelope is wide, whether overhead width, printing outward appearance, heat seal strength all meet code requirement, the friendship surge chamber that is up to the standards, waits for product inspection;
H, product inspection: press final inspection code requirement, each batch of finished product inspected by random samples, the qualified qualified mark of mark, waits to be released; Underproofly do over again or scrap;
I, warehouse-in: finished product is paid stores keeping.
In described c step, oven temperature used is 42-48 DEG C, and baking roll temperature is 39-45 DEG C, and rotating speed is 25-30m/min.In described g step, sealing compressing temperature is 155-165 DEG C, and speed is 55-70/point.
Advantage of the present invention is: preparation technology is simple, easy and simple to handle, preparation glue process, and the limpid no-sundries of glue, is convenient to next step printing, and packaging bag air-tightness that this technique prepares is high, intensity is high; There is good resistance bacterium property, bacterial barriers and clean openability; Packaging bag is torn rear without paper scrap; Packaging bag, after sterilizing, can not cause content and packaging bag bonding.
