4, food packaging should have sufficient thickness and strength, in order to ensure food bag.

custom packaging requires the following process:

a: design

good packaging specification, material, thickness and type bag, and according to these data to make design draft packing bags of the designer or manufacturer, can design a few more, design to give some reference and ultimately determine the bag. Especially when the design should pay attention to the words on the packet information, pay attention to the following content: packaging manufacturer name, ingredients such as iron, calcium sodium, etc. , product introduction, origin, turnning is mainly a g/kg, specifications, food labels, QS certification, hygiene license number, production date, storage conditions and shelf life, food use method, name of manufacturer, address and contact phone number, including QS and barcode must not be less.

step 2: plate making

after the drawings to determine, need professional technicians to design color separation, do repair for some not clear place, at the same time also need a dozen process to complete the process, here not introduce one by one, if you need to understand the details can be seen. Third step:

print

after the raw material to prepare using high-speed presses will be printing surface membrane ( When printing each color has a plate roll, plate rolling is carved intaglio engraving) , when the printing ink is continuously flowing, because the ink condenses, during the printing ink printing and membrane with a scraper, scraper is on board scrape ink roll out, such a hollow plate rolling can be printed. If the blade is stained with dirt on strips of ink pollution phenomenon will occur. Because ink for dot ink pollution phenomena in rolling printing ink splashed onto the packaging film and cause the dot of ink pollution.

step 4: composite

after the printing surface membrane and easy to heat sealing layer of film with special glue dedicated high-speed peritoneal machine for composite.

step 5: curing

after the compound need in more than 45 degrees curing chamber for 24 hours aging, in order to make food packaging is not easy to take off a layer.

step 6: bag

the packing bags of food production has been coming to an end, bag making technician is the need to have certain skills, must ensure that the color bags not leak sealing side is good, the temperature control of the hot knife has certain technical. After the qc inspectors inspection factory.

step 7: quality

main test items: packet size (long mm） , wide ( mm） , thick ( 嗯) , appearance, overprint error, off color, peel strength, heat sealing strength.

1, the length, the width is the ruler, the thickness of the test using the thickness gauge, detection methods are the same as we test.

2, to examine the color difference, mainly is through sealed samples with the standard check at arm distance color difference should be consistent. In terms of color in the printing factory also through a magnifying glass to 50 times to check the print color, color is general by a branch of a combination, if the wrong color so outlets will be irregular distribution. Are the rules of the general branch and branch are round

3, to overprint error checking is mainly visual presence of the phenomenon of double printing.

step 8: put in storage

on the packing bag of quality inspection qualified, good for packaging, at the same time into the unified management of warehouse, so that the late delivery is convenient.

step 9: shipment

after packaging warehousing, customer contact, according to the near and far, far logistics, close to delivery. Far logistics distribution ( Ensure no damage to the goods) , close to free delivery to the door.
