The production process of container inflatable bag is mainly to tell you how to make the container inflatable bag, which is divided into 9 steps:
Step 1: Cut out the inner pocket membrane
According to the required inner bag size, the technical worker adjusts the film cutting machine data, and the sample is checked without error, and then the worker begins to operate. The first 50 sheets of intima need to check the sealing edge one by one. After that, spot check every 100 (5-10 in a row) for sealing of the edge. After completion, it is divided into 10-20 inner bags according to their size for twice folding, and then transported to the next station neatly.
Step 2: punch holes in the inner pocket
(1) For the inner pocket transmitted from the first working position, small or large air valve holes shall be set according to the order requirements.
(2) When punching, punch should be carried out according to the punching position marked on the punching machine to avoid skewering, which may lead to inconsistency with the outer bag hole.
Step 3: Install air valve and hot melt seal
(1) For the perforated inner bag transmitted from the second working position, the air valve is installed at the perforated inner bag, and the hot melt seal is carried out by the hot melt equipment.
(2) Before the hot melt machine starts working, it is necessary to check whether the temperature of the machine reaches the specified temperature. After the hot melt seal is completed, it is transferred to the next station.
(3) Special attention: due to the unstable temperature of the machine before starting, the sealed edge will appear and the hand can be torn apart. After the hot melt sealing of the first 50 inner bags, the sealing effect of the air valve and edge sealing should be checked one by one.
Step 4: Drill the kraft paper outer bag
(1) The kraft paper outer bag is cut according to the corresponding specifications by the bag cutting machine, and the small air valve hole or large air valve hole is set according to the order requirements.
(2) When punching, punch should be carried out according to the punching position marked on the punching machine to avoid skewering, which may lead to inconsistency with the inner pocket hole.
(3) The perforated outer bag is placed in the designated position to facilitate the work of the next station.
Step 5: Combine inner and outer pockets
This position is completed by two workers.
(1) Two people work together to stretch the outer bag into a similar cylinder. The worker in charge of the inner bag folds the inner bag twice, holds the upper part of the outer bag with one hand, and slowly pushes the inner bag into the outer bag with the other hand, and inserts the air valve into the outer bag (don't leave long fingernails).
(2) The worker at the other end will receive the inner bag in time. After two people are connected, the inner bag will be straightened together until there is no folding.
(3) The workers at the air valve end decide whether to fold the inner bag according to the actual situation of the inner bag to prevent air leakage caused by sewing into the inner bag.
(4) Workers without air valve ends should fold the inner pocket inward 10cm to prevent air leakage from being sewn into the inner pocket during sewing.
(5) Workers without air valve ends should fold the inflatable bags according to the regulations and put them neatly at the next station after the completion of both processes.
Bagging Note: After the inner bag is packed, pay attention to check whether the edge is sealed and make the last check.
Step 6: Sewing
(1) According to the inflatable bag passed by the staff at the last working station, the sewing work shall be carried out according to the prescribed sewing edge distance and needle distance.
(2) Before sewing, check whether the inner pockets at both ends are folded or not. If the inner pockets are not folded, sew them after folding. Remind the bagging personnel to fold the inner pockets.
(3) After the sewing is finished, put it neatly into the next station.
Step 7: Glue
(1) Take the neatly stacked inflatable bags to the gluing place, and check whether the machine temperature and gluing speed are up to the standard.
(2) Two people cooperate with each other to use glue equipment to seal the sewing areas on both sides of the inflatable bag with kraft paper hot melt tape
(3) personnel conveying inflatable bag over glue, pay attention to the inflatable bag and inflatable bag over glue to maintain at least 1cm distance between the middle, easy to shear.
(4) When using scissors to cut short hot melt tape, we must pay attention to the cutting position, do not cut to the inside of the inflatable bag, to prevent cutting to the inner membrane, resulting in air leakage.
(5) when the first side is gluing, the cutting should be placed neatly to facilitate the operation of the second side.
After gluing the second side, the shearing personnel can throw the inflatable bag straight on the designated desk.
(6) When the last inflatable bag is too glue-filled, the shear personnel should tighten the hot melt tape to prevent the tape from being wrapped on the machine and affecting the work.
Step 8: Pack into a bundle
(1) After gluing, 10 inflatable bags should be packed together into bundles. Before packing, excess thread ends and hot melt tape should be cut off to ensure beautiful appearance.
(2) Pack the first 10 together and place them on the packing table. Small air valves are installed with handle, black inner plug and air valve cover in turn, and tighten; The large air valve is directly installed with the handle, and make sure the handle is stuck in the slot.
(3) After the installation of the air valve is completed, the valve should be packed according to the specified size and placed neatly on the specified tray.
(4) In the case of less than 10 packages, mark the actual number with labels to avoid errors in packing quantity.
Step 9: Pack
(1) According to the size of the kraft paper inflatable bag and the corresponding carton size, pack it neatly and orderly, and label the packed carton.
