Abstract
The invention discloses a production technology of a plastic-coated three-dimensional bag. The production technology comprises the steps of plastic coating, gum solution preparing, printing, bag making, finished product inspecting and storage in a storehouse. The production technology has the advantages that the technology is simple, operation is simple, in the gum solution preparation process, the gum solution is clear without impurities, the next step namely printing is facilitated, and the packaging bag made through the technology is good in breathability and bacteria resistance and is firmly sealed; after sterilization, objects in the packaging bags can not be bonded with the packaging bag.
Description
Technical field
The present invention relates to a kind of production technology of plastic-coated stereoscopic bag, belong to medicine equipment flexible package production field.
Background technology
There is following shortcoming in the now packaging bag in medicine equipment Flexible Package Market: resistance bacterium property is poor, it is insecure to seal; Packaging bag is airtight; Packaging bag cannot be torn, and tearing rear breakage has paper scrap; Because glue preparing process is different, to dissolve not thoroughly, temperature is not controlled well, and other techniques are affected, and cause the packaging bag quality produced general.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The object of this invention is to provide a kind of production technology of plastic-coated stereoscopic bag simple to operate, the paper bag that this production technology prepares has gas permeability and hinders the advantages such as bacterium property is good, sealing is firm, be convenient to tear.
The technical solution used in the present invention is:
The production technology of plastic-coated stereoscopic bag, comprises the following steps:
A, plastic-coated: get the medical body paper of 38g and low density polyethylene (LDPE) particle according to technological requirement from raw material storage, low density polyethylene (LDPE) particle dissolves through 280 DEG C-320 DEG C of compounding machines, form film-form, is bonded together through compression roller with medical body paper.After oven dry, rolling moulding.Cut into different specifications according to production requirement, i.e. plastic-coated paper roll.Inspection plastic-coated paper grammes per square metre 62g/ ㎡ ± 3g/ ㎡, surface-coated is evenly without holiday, burning silk, greasy dirt, black impurity etc.;
B, printing: require plastic-coated paper roll and the ink got according to technique list, plastic-coated paper roll is placed on the unwinding rack of printing machine, allocate by customer requirement getting ink, allocate after qualified and pour ink fountain into, open printing machine power switch, regulate unwinding and rewinding tension force, bring into operation, plastic-coated paper is through the positive printing of traction paper, after 70 DEG C of-120 DEG C of hyperthermia dryings, rolling is embarked on journey, and becomes plastic-coated printing volume; Be up to the standards and hand over semi-finished product warehouse;
C, bag: require to get from semi-finished product warehouse plastic-coated paper printing volume according to technique list, plastic-coated printing volume is fixed on to unreeling on support of three side sealing bag machines, material is compressing through mould sealing through drawing-off, sealing compressing temperature is 170 DEG C ± 5 DEG C, speed reaches 50-80/point, 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, inspection envelope is wide, whether overhead width, printing outward appearance, heat seal strength all meet code requirement, and the friendship surge chamber that is up to the standards, waits for product inspection;
D, 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;
E, warehouse-in: finished product is paid stores keeping, guarantee that product storage is intact.
In described a step, bake out temperature is 300 DEG C-320 DEG C.
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 the packaging bag gas permeability that this technique prepares and resistance bacterium property are good, sealing is firm; Packaging bag is torn rear without paper scrap; Packaging bag, after sterilizing, can not cause content and packaging bag bonding.
